MAX5420 Datasheet (Maxim Integrated Products) - Digitally Programmable Precision Voltage Divider

MAX5420, Digitally Programmable Precision Voltage Divider

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
