High-res audio amp designed for automotive apps

March 3, 2021 By Charlie Flor

The HFDA801A from STMicroelectronics is a high-resolution audio amplifier that is specifically designed for compact, cost-effective automotive applications. The HFDA801A is a 2MHz switching pulse-width modulation (PWM) Class-D amplifier with a quad-bridge configuration. An integrated high-performance digital-to-analog converter (DAC) ensures hi-fi quality sound under any load condition, with noiseless turn-on/turn-off and without creating any output artifacts. With a signal-to-noise […]

Dual 5-V op amp sports 50-MHz gain-bandwidth, low input offset voltage, 6.5 nV/√Hz input voltage noise

December 8, 2020 By Redding Traiger

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. […]
