Part Details
The MAX5420 and MAX5421 are digitally programmable precision voltage dividers optimized for use in digitally programmable gain amplifier configurations. The MAX5420/MAX5421 operate from a single +5V supply or dual ±5V supply, and consume only 3µA supply current. These devices consist of a digitally selectable resistor array that provides four precision noninverting gains of 1, 2, 4, and 8 for PGAs. The MAX5420 and MAX5421 achieve a resistor ratio accuracy of 0.025% (MAX542_A), 0.09% (MAX542_B), and 0.5% (MAX542_C). The MAX5421 includes an on-chip matching resistor for op amp bias-current compensation.
The MAX5420 and MAX5421 are available in 8-pin and 10-pin µMAX packages. The devices are specified over the extended temperature range (-40°C to +85°C).
