The MAX5430/MAX5431 are digitally programmable
high-precision resistor arrays for PGAs. The MAX5430/
MAX5431 operate from a single 15V supply or dual
±15V supplies, and consume only 35µA 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 1, 2, 4,
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.
The MAX5430/MAX5431 are available in space-saving
8-pin SOT23 and 10-pin µMAX
fied over the extended temperature range of (-40°C to
+85°C).
