  • Product Details

    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, 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.

    The MAX5430/MAX5431 are available in space-saving 8-pin SOT23 and 10-pin µMAX packages, and specified over the extended temperature range of (-40°C to +85°C).
