19-2222; Rev 2; 7/05
±15V Digitally Programmable
Precision Voltage-Dividers for PGAs
General Description
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® packages, and speci-
fied over the extended temperature range of (-40°C to
+85°C).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
