STMicroelectronics’ TSV792 dual 5V operational amplifier 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. By efficiently processing the photodetector output signal, the TSV792 saves energy for extra features such as wireless networking that add value to smart-home products.

With typical input offset voltage of 50µV (at 25°C), the TSV792 performs accurate low-side current sensing in motor-control applications and power systems such as industrial power supplies, telecom and network infrastructure supplies, and renewable-energy conversion (more info).
