STCD1020/40 - multi-channel clock distribution circuit

The multi-channel RF clock distribution circuits, STCD1020/40, are the first in the market that can be used in mobile phones, MIDs and other applications. Their design provides key advantages over traditional buffers, such as cost savings (requiring only one source crystal for common frequency applications), board space savings, exceptionally good phase noise performance, good channel-to-channel isolation and low quiescent current.

The features enabled by the two new families allow mobile network operators to enhance differentiation and expand revenue growth by delivering richer services to subscribers. More

SuperMESH3™ MOSFETs - lower conduction and switching losses in lighting and SMPS applications

The innovative 625 V and 525 V SuperMESH3 power MOSFETs guarantee higher efficiency thanks to their lower on-resistance. They exhibit excellent dv/dt performance and higher breakdown-voltage margins, providing enhanced reliability and safety for your design. More

TS4961T mono class D audio power amplifier with dedicated analog switch

ST has introduced the TS4961T filter-free, mono class D audio amplifier system for portable applications using an ultra-high off isolation analog switch with advanced pop and clickless circuitry. The TS4961T mono class D amplifier is part of a new line of products focused on handset architectures. As this is the first device to combine audio amplification and high off isolation analog for all handset speakers, the TS4961T saves more that 50% of board space compared to previous integrated solutions using two ICs with external resistors, and up to 80% compared to alternative discrete solutions. All necessary biasing circuitry is also integrated, thereby minimizing external components. The TS4961T proposes versatile features for the latest generation of portable applications. More

TSH122 ultra-low-power video buffer unlocks extra battery life for mobile video products

The TSH122 combines low operating current and the industry’s lowest standby power for longer time-before-recharge in portable consumer devices. Mobile video devices, including digital cameras, camera phones and personal media players, can run longer using the new TSH122 video buffer IC. This new device has a low operating current of 1.7 mA and draws the lowest standby current among comparable devices, at just 4 nA typical, 500 nA maximum. More

TS507 high-precision ultra-low input offset voltage rail-to-rail op-amp

The TS507 is a new high-precision, single-channel op-amp featuring an ultra-low input offset voltage of only 25 µV typical and 100 µV maximum. This high precision is obtained by trimming after packaging, using a patented adjustment technique. The main advantage of adjustment after packaging is that you eliminate offset voltage drift due to encapsulation. In addition to a low offset voltage, the TS507 demonstrates excellent DC parameters, an open-loop gain of 131 dB (typ.) on a 5 V supply and a PSRR of 105 db (typ.). Operating at low supply voltages from 2.7 to 5.5 V, the TS507 has a rail-to-rail configuration on both its input and output. It can also deliver high output current (up to 130 mA in a short-circuit configuration) and can drive high capacitive loads. It consumes 850 µA and has a gain bandwidth product of 1.9 MHz. The TS507, like the recent TSV91x and TSV99x, has an exceptional ESD tolerance of above 5 kV in HBM. More

SMA6F: 600W high temperature TransilTM in flat SMA package

The SMA6F is the first 600 W Transil series packaged in a flat SMA, so offering real space saving without compromising the performance. The increased thinness of this package (1 mm) provides a greater flexibility in the PCB design. More

ST releases first speech-codec software library with STM32

ST is expanding the STM32 family capabilities by releasing the first speech-codec software library. The library is based on the Speex open-source format and enables you to transmit longer messages and store more speech data. The Speex codec high-compression format and low e-memory footprint allows developers to design cost-effective solutions for narrowband bit rates. The library is free and available for download from ST's web site. More

ST715 -high input voltage, 85 mA micro-power low dropout regulator prolongs battery life

The ST715 prolongs battery life by sinking a small current, even in the worst operating conditions. It delivers 85 mA while consuming only 3.8 µA at ambient temperature. The wide input voltage range (from 2.5 to 24 V) and the low dropout voltage prolong the battery’s life allowing it to deliver power to loads even with minimum input-to-output voltage differentials. Output voltage stability is also guaranteed by ceramic capacitors. The device has a full set of protection features such as short-circuit current limitation, and thermal shutdown and is housed in the extremely small SOT23-5L or MLP 3 x 3 8L packages. More

TS4601 high-performance stereo headphone amplifier with capacitorless outputs and I²C bus interface

The TS4601 is a flexible, high-performance stereo headset amplifier, dedicated to high audio quality in portable applications, and provides long playback times. It is based on a low power dissipation amplifier core technology. It can drive headphones with a minimum 16-ohm load, whilst demonstrating high stability. The traditionally used output-coupling capacitors can be removed thanks to the ground referenced outputs, and a dedicated common-mode sense pin removes parasitic noise from the jack. The TS4601 performs the highest PSRR (107 dB) of the portable headset amplifier industry. More

TSV91x and TSV99x rail-to-rail CMOS input op-amps

Two new families of low-voltage single, dual and quad op-amps, the TSV911/2/4 and TSV991/2/4, are now available from ST. With rail-to-rail inputs and outputs, and offering up to 20 MHz of bandwidth, these multi-segment products provide an excellent speed/consumption ratio. Their supply range extends from 2.5 up to 5.5 V. The new TSV91x and TSV99x families feature CMOS inputs with a bias current of only 1 pA (typical value, 10 pA maximum), making them ideal for high-impedance sensor signal conditioning. The high merit factor of these op-amps allows for relatively low consumption while providing a high gain bandwidth product at 2.5 V. More
