概述
The TPA158 is a series of high-side current-sense amplifiers with high common voltage. The TPA158 series has very high precision and accuracy specifications of VOS less than 150 μV (max) and gain error less than 0.55% (max). Five fixed gains are available: 20 V/V, 50 V/V, 100 V/V, 200 V/V, and 500 V/V. These options provide a wide dynamic range for current-sensing applications.
The TPA158 series features an input common-mode voltage range from 3 V to 150 V with 1-MHz bandwidth, which makes it ideal for small-signal conditioning interfacing with a SAR ADC.
The TPA158 offers breakthrough performance throughout the −40°C to +125°C temperature range. It features a zero-drift core, which leads to a maximum offset drift of 0.1μV/°C throughout the operating temperature range and the common-mode voltage range. The TPA158 is offered in the SOT23-5 package.
