TSV772 is a dual operational amplifier extending ST’s 5V op-amp family. The op-amp has rail-to-rail inputs and outputs, it is a dual 20MHz-bandwidth, unity-gain stable amplifier. It offers a maximum of 200µV as input-offset voltage and ensures accurate handling of low-amplitude signals. The op-amp is capable of starting from a low input voltage of 2V and can be connected to the same rail as a low-power microcontroller to simplify the design. The Op-amp offers a slew rate of 13V/µs, 7nV/√Hz input noise density, and 4kV ESD capability (HBM). The component comes in a compact DFN8 package.
According to the company, the 5V, 22MHz TSV7722 is optimized for low-side current sensing and is trimmed for a common mode close to the ground. The op-amp ensures a maximum input offset voltage of 200µV (at 25°C) which 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 characterized by an output capacitance of 47pF, simplifying its use as an A/D converter input buffer.
The TSV772 dual operational amplifier combines high accuracy, low power consumption, and the option of an extremely small 2.0mm x 2.0mm DFN8 package. It can be employed in applications which require high efficiency, high-speed operations in order to improve accuracy and extend the operating lifetime of the system. This op-amp can also enable accurate current measurement as the starting point for efficient power conversion in systems such as telecom and communication infrastructure, solar farms and solar generators, data centres and computer servers. Other application includes smoke detectors which can utilize the op-amps
The 5V op-amp family includes a 50 MHz TSV792 along with the 22 MHz TSV772. The TSV772 is in production and available in SO-8, MiniSO-8 and the compact DFN8 package. Free samples of the device can be obtained from the authorized distributors.
