MAX5426：Precision Resistor Network for Programmable Instrumentation Amplifiers

The MAX5426 is a precision resistor network optimized for use with programmable instrumentation amplifiers. The MAX5426 operates from dual ±5V to ±15V supplies and consumes less than 40µA of supply current. Designed to be used in the traditional three op amp instrumentation amplifier topology, this device provides noninverting gains of 1, 2, 4, and 8 that are accurate to 0.025% (A-grade), 0.09% (B-grade), or 0.5% (C-grade) over the extended temperature range (-40°C to +85°C). The MAX5426 is available in the 6.4mm x 5mm 14-pin TSSOP package.
