The TPA1295 family is of high voltage, Bi-directionalcurrent sense amplifier with voltage output. The TPA1295 cansense drops across shunts at common-mode voltages from –0.3V to 70 V. The TPA1295 are available with three outputvoltage scales: 20V/V, 50V/V, 100V/V, with up to 500KHzbandwidth.The TPA1295 operates from single 3V to 18V supply, offersbreakthrough performance throughout the −40°C to +125°Ctemperature range. It features a zero-drift core, which leads toa typical offset drift of 0.4μV/°C throughout the operatingtemperature range and the common-mode voltage range.The TPA1295 family is offered in 8-pin SOP package.
