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.

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 3A 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 MAX packages. The devices are specified over the extended temperature range (-40°C to +85°C).
