Overview
The TPA1295 is a series of high-voltage, Bi-directional current sense amplifiers with voltage output. The TPA1295 can sense drops across shunts at common-mode voltages from −0.3 V to 70 V. The TPA1295 is available with three output voltage scales: 20 V/V, 50 V/V, and 100 V/V, with up to 500-kHz bandwidth.
The TPA1295 operates from single 3-V to 18-V supply, and offers breakthrough performance throughout the temperature range from −40°C to +125°C. It features a zero-drift core, which leads to a typical offset drift of 0.4 μV/°C throughout the operating temperature range and the common-mode voltage range.
The TPA1295 series is offered in the SOP8 package.
