TSV772 Series Operational Amplifiers

STMicroelectronics' TSV772x are a series of dual 20 MHz or 22 MHz bandwidth unity-gain-stable amplifiers. The input offset voltage of 200 μV max (50 μV typ.) at room temperature, optimized for common-mode close to ground, make them ideal for low-side current measurement. They operate from a single supply range and are fully specified on a load of 47 pF, allowing them easy usage as A/D converters’ input buffer.

The TSV7722IST can operate from 1.8 V to 5.5 V single supply. It offers rail-to-rail output, excellent speed/power consumption ratio, and 20 MHz gain bandwidth while consuming just 1.7 mA at 5 V. The device features an ultra-low input bias current that enables connection to photodiodes and other sensors where current is the key value to be measured.

The TSV772IQ2T can operate from a 2.0 V to 5.5 V single supply. It is a dual 20 MHz bandwidth unity-gain-stable amplifier. The rail-to-rail input stage and the slew rate of 13 V/µs make it ideal for low-side current measurement. The excellent accuracy provided by maximum input voltage of 200 µV allows accurate amplification of small-amplitude input signal.

The TSV7723IST can operate from 1.8 V to 5.5 V single supply. It is a dual 22 MHz bandwidth unity-gain-stable amplifier. It offers rail-to-rail output, excellent speed/power consumption ratio, and 22 MHz gain bandwidth product, while consuming just 1.7 mA at 5 V. The device also features an ultra-low input bias current that enables connection to photodiodes and other sensors where current is the key value to be measured.
