MAX34406FETG+T

Current Regulation/Management Overview

The MAX34406FETG+T is a quad current sense amplifier from the Analog Devices / Maxim Integrated MAX34406 series. It features four independent channels in a TQFN-24 package, supporting surface mount installation. The device operates with a common-mode voltage range of 2 V to 28 V and offers selectable gains of 25 V/V, 50 V/V, 100 V/V, or 200 V/V. Key electrical specifications include a 120 dB common-mode rejection ratio (CMRR), an input offset voltage of 100 uV, a gain error of 0.6%, and a 3dB bandwidth of 125 kHz. It provides a voltage output type and functions within a temperature range of -40°C to +85°C.
