概述

The TPA131C is a family of high-voltage, high-side current-sense amplifiers with voltage output, internal comparator, and voltage reference. The TPA131C can sense drops across shunts at common-mode voltages from –4 V to 80 V. The TPA131C has five output voltage scales: 20 V/V, 50 V/V, 100 V/V, 200 V/V, and 500 V/V with up to 1-MHz bandwidth.

The TPA131C features one open drain comparator with internal 0.6-V references. The comparator works with a latching capability.

The TPA131C operates from single 3.0-V to 5.5-V supply, offers breakthrough performance throughout the −40°C to +125°C temperature range. It features a zero-drift core, which leads to an offset drift of 0.5 μV/°C throughout the operating temperature range and the common-mode voltage range.

The TPA131C is offered in the MSOP8 package.
