MAX5421BEUB+

The MAX5421BEUB+ is a digitally programmable precision voltage divider for digitally programmable gain amplifier (PGA) configurations in 10 pin µMAX package. The device operates from single +5V supply or dual ±5V supply and consumes only 3µA supply current. It consists of digitally selectable resistor array that provides four precision non-inverting gains of 1, 2, 4 and 8 for PGAs. The MAX5421B achieves a resistor ratio accuracy of ±0.09% and includes an on-chip matching resistor for op amp bias current compensation. It is typically designed for general purpose programmable non-inverting amplifiers.
