19-2222; Rev 1; 1/02 www.DataSheet4U.com ±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 resistor-dividers. Each device has digitally controlled contacts 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.
