ꢃrecision ꢀoltaꢁe-Dividers for ꢃGAs

General Description

Features

The MAX5430/MAX5431 are digitally programmable

high-precision resistor arrays for PGAs. The MAX5430/

MAX5431 operate from a single 15V supply or dual

15V suppliesꢀ and consume only 35ꢁA supply current.

These devices are intended for programmable-gain

amplifier (PGA) applications and consist of fixed resis-

tor-dividers. Each device has digitally controlled con-

tacts with four precision noninverting gains of 1ꢀ 2ꢀ 4ꢀ

and 8 with ratio accuracy of 0.025% (MAX5430A/

MAX5431A)ꢀ 0.09% (MAX5430B/MAX5431B)ꢀ or 0.5%

(MAX5430C/MAX5431C). The MAX5431 includes an

on-chip matching resistor for op amp input bias-current

compensation.

Packages

The MAX5430/MAX5431 are available in space-saving

8-pin SOT23 and 10-pin ꢁMAX packagesꢀ and speci-

fied over the extended temperature range of (-40°C to

+85°C).
