The STMicroelectronics TSV772 dual operational amplifier (op-amp) combines high accuracy, low power consumption and the option of an extremely small 2,0 x 2,0 mm DFN8 package.
Extending ST’s high-performance 5 V op-amp family, the TSV772 has rail-to-rail inputs and outputs, 20 MHz gain-bandwidth (GBW), and is unity-gain stable. With a slew rate of 13 V/µs, 7 nV/√Hz input noise density and 4 kV ESD capability (HBM), the TSV772 is a strong all-round performer.
The maximum input-offset voltage of 200 µV (at 25°C) ensures accurate handling of low-amplitude signals. The inherent accuracy also saves using expensive, precision external resistors and helps avoid trimming or calibrating circuits in production. The TSV772 is characterised for an output capacitance of 47 pF, simplifying use as an A/D converter input buffer.
Capable of operating from a supply voltage as low as 2,0 V, the TSV772 can be connected to the same rail as a low-power microcontroller to simplify design. The low minimum voltage also allows longer operation with a deeply discharged battery.
The TSV772 is suited for applications such as smoke detectors. These can leverage the op-amp’s speed and efficiency to save battery energy for powering smart features, wireless connectivity and extended operating lifetime. The device also enables accurate current measurement as the starting point for efficient power conversion in systems such as solar generators, telecom infrastructure equipment and computer servers.
In addition to the TSV772, ST’s high-performance 5 V op-amp family includes the dual-channel 50 MHz TSV792 and 22 MHz TSV7722. The TSV7722 is optimised for low-side current sensing and is trimmed for a common-mode close to ground.
