Dual 5-V op amp sports 50-MHz gain-bandwidth, low input offset voltage, 6.5 nV/√Hz input voltage noise
STMicroelectronics’ TSV792 dual 5V operational amplifier (op-amp) combines 50MHz gain-bandwidth with precision attributes including low input offset voltage and extremely low input voltage noise of just 6.5nV/√Hz. The typical 50MHz gain-bandwidth product enables accurate amplification of high-frequency signals. Adding a fast slew rate of 30V/µs, the TSV792 is suited to photodiode-signal conditioning in battery-powered smoke detectors. […]
Single-chip drivers for low- to mid-power motor control designs

STiD135 demodulator chip targets satellite use
STMicroelectronics announced the volume production of the world’s first 500Mbaud High Symbol Rate (HSR) integrated tuner-demodulator chip, selected by its lead customer Newtec, a specialist in designing, developing, and manufacturing equipment and technologies for satellite communications. Designed to increase bandwidth-usage efficiency and throughput in high-end satellite and hybrid broadband-broadcast applications, the STiD135 demodulator supports the […]
Tiny 3-MHz chopper op amps feature rail-to-rail input and output
The TSZ182 dual precision op amp from STMicroelectronics combines low and extremely temperature-stable input-offset voltage with the added advantages of a 3MHz gain-bandwidth, rail-to-rail inputs and outputs, and ultra-small 2mm x 2mm DFN8 or Mini-SO8 package options. Complementing ST’s popular conventional op amps, the chopper-stabilized TSZ182 enables superior precision in instruments like body-signal monitors, blood-glucose […]
MEMS sensors extend battery life of devices hosting always-on activity-tracking apps
STMicroelectronics has introduced three new sensors, the LIS2DS12 3-axis “pico” accelerometer, LSM6DSL/M 6-axis inertial module, and the new LSM303AH eCompass help track movement continuously with minimal impact on device battery life by performing various motion-related calculations efficiently on-chip instead of using the main system processor. Pre-embedded algorithms that include high-precision pedometer, step detection, step counting, […]
Nano-Power op amp boosts sensing accuracy
With its tiny 1.2mm x 1.3mm outline and typical current of only 900nA, the TSU111 nano-power op amp from STMicroelectronics helps cut the size and energy needs of analog circuits to the bare minimum in medical monitors, wearable electronics, gas detectors, pH sensors, infrared motion sensors, and payment tags. The TSU111’s extremely low operating current […]
