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
5mm 14-pin TSSOP package.
19-2318; Rev 0; 1/02
Pin Configuration and Functional Diagram appear at
end of data sheet.
