Ultra-compact dual-channel operational amplifier 'TSV772'

STMicroelectronics (hereinafter ST) has introduced a 20MHz operational amplifier that achieves high accuracy and low power consumption.

On the 28th, ST released the TSV772 dual-channel operational amplifier (Op Amp) with an ultra-small 2.0mm x 2.0mm DFN8 package option.

The TSV772, a new addition to ST's high-performance 5V operational amplifier family, features rail-to-rail input and output, a gain-bandwidth of 20 MHz, a slew rate of 13 V/µs, an input noise density of 7 nV/√Hz, and 4 kV ESD performance (HBM).

The TSV772 accurately processes low-amplitude signals with a maximum input offset voltage of 200µV (at 25°C), helping users skip the task of trimming or correcting circuits during production and avoiding the use of expensive external precision resistors.

In addition, it is characterized by an output capacitance of 47pF, making it easy to use as an input buffer for an A/D converter.

Because the TSV772 can operate at a low supply voltage of 2.0V, it simplifies the design by connecting to the same rail as low-power microcontrollers, and due to its low minimum voltage, it can operate even when the battery is significantly discharged It has the feature of being able to operate for a long time.

It is suitable for applications such as smoke detectors, and these applications can save battery energy required for smart functions, wireless connectivity, and long operating times by utilizing the speed and efficiency of this operational amplifier.

In addition, accurate current can be measured at the input for efficient power conversion of systems such as solar power generators, communication infrastructure equipment, and computer servers.

In addition to the TSV772, ST's high-performance 5V operational amplifier family includes the dual-channel 50MHz TSV792 and the 22MHz TSV7722. The TSV7722 is optimized for low-side current sensing and is trimmed to common mode close to ground.

The new 20MHz TSV772 dual-channel operational amplifier is currently in production and is available in SO-8, MiniSO-8, and small DFN8 packages.
