TSV77xシリーズ：20MHzの広帯域かつ200µVの入力オフセット電圧を特徴としたレール･ツー･レール入出力の5Vオペアンプ

Designed to accurately measure current with the minimum shunt resistor value, TSV771 (single) and TSV772 (dual) op amps reduce power dissipation avoiding hot spots on the PCB and minimizing the cost of the shunt.

Primarily used to measure current in power conversion systems, these high-bandwidth 5V op amps are ideal for solar panels, telecom infrastructure or computer servers. An automotive-grade version is also available to meet the most demanding quality standards of this market segment.

Able to accurately amplify small-amplitude input signals with 200 µV accuracy, these fast op amps can also be used with photodiodes, which are widely used in smoke detectors. In addition to enabling a longer battery lifetime, their low input bias current is perfect for interfacing with connected devices as the energy saved by using TSV77x can be used to supply a microcontroller and wireless connection.
