AD8205WHRZ-RL

Instrumentation, Op Amps, Buffer Amps Overview

The AD8205WHRZ-RL is a single-supply difference amplifier designed for high-side current sensing in automotive and industrial systems. It features a fixed gain of 50 V/V, an operating common-mode voltage range from −2 V to +65 V, and a survival range up to +75 V. The device operates on a 4.5 V to 5.5 V supply with a quiescent current of 2 mA. It offers excellent DC performance with offset drift of 15 µV/°C and gain drift of 30 ppm/°C. The component is qualified for automotive applications and supports bidirectional operation within an 8-lead SOIC package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'W' indicates automotive qualification and 'H' denotes the extended temperature grade up to +150°C. Confirm the '-RL' suffix corresponds to the 13-inch tape and reel packaging format. Ensure the design accounts for the 8-lead SOIC_N physical dimensions and thermal characteristics appropriate for the target application environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this model when automotive reliability is required alongside extended temperature operation up to +150°C. The W-grade designation ensures compliance with automotive manufacturing standards. Consider the fixed 50 V/V gain and high common-mode rejection ratio for precise current measurements in noisy electrical environments typical of vehicle powertrains.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the AD8205 family of single-supply difference amplifiers. The AD8205 series provides high accuracy for measuring small differential voltages in the presence of large common-mode signals. The W and H grades specifically address automotive durability and high-temperature operational requirements compared to standard commercial variants.
