General Description
The MAX5420 and MAX5421 are digitally programmable
precision voltage dividers optimized for use in digitally pro-
grammable gain amplifier configurations. The MAX5420/
MAX5421 operate from a single +5V supply or dual ±5V
supply, and consume only 3A supply current. These
devices consist of a digitally selectable resistor array that
provides four precision noninverting gains of 1, 2, 4, and 8
for PGAs. The MAX5420 and MAX5421 achieve a resistor
ratio accuracy of 0.025% (MAX542_A), 0.09% (MAX542_B),
and 0.5% (MAX542_C). The MAX5421 includes an on-chip
matching resistor for op amp bias-current compensation.
The MAX5420 and MAX5421 are available in 8-pin and
10-pin MAX packages. The devices are specified over
the extended temperature range (-40°C to +85°C).
