MAX5420AEUA+

The MAX5420AEUA+ is a digitally programmable precision voltage divider for digitally programmable gain amplifier (PGA) configurations in 8 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 MAX5420A achieves a resistor ratio accuracy of 0.025%. It is typically designed for general purpose programmable non-inverting amplifiers.
