概述
The TPA3531 and TPA3532 operational amplifiers feature very low input bias current. They operate from 4.5 V to 16 V (±2.25 V to ±8 V), and feature rail-to-rail output swing in addition to an input common-mode range that includes ground. The integrates guard buffer isolates the input pins from leakage in the printed circuit board. They minimize board component counts and enable easy system design.
The TPA3531 and TPA3532 are ideal for portable medical and industrial applications that require low-bias current analog front-end performance, such as photodiode transimpedance and chemical sensor interface circuits.
The TPA3531 and TPA3532 are available in the SOT23-5, MSOP8, and SOP8 packages, and are specified over the industrial temperature range from –40°C to +125°C.
