Maxim Integrated MAX5431AEUB T

Description
The MAX5430/MAX5431 are digitally programmable precision resistor arrays designed for programmable-gain amplifiers (PGAs). They operate from a single 12V to 15V supply or dual ±12V to ±15V supplies, consuming only 35μA of supply current. These devices consist of fixed resistor-dividers with digitally controlled contacts, providing four noninverting gain configurations: Ay = 1, 2, 4, and 8. The MAX5431 includes an on-chip matching resistor for op-amp input bias-current compensation.
