General Description

The MAX5430/MAX5431 are digitally programmable high-precision resistor arrays for PGAs. The MAX5430/ MAX5431 operate from a single 15V supply or dual ±15V supplies, and consume only 35µA supply current.

Features

♦ Four Noninverting PGA Gain Configurations: AV = 1, 2, 4, and 8

♦ Precision 0.025 Ratio Accuracy

♦ On-Chip Matching Resistor for Op Amp BiasCurrent Compensation (MAX5431)

♦ Single-Supply +12V to +15V, or Dual-Supply ±12V to ±15V Operation

♦ Low 35µA Supply Current

♦ CMOS/TTL Logic Compatible 2-Wire Parallel Interface

♦ Space-Saving 8-Pin SOT23 and 10-Pin µMAX Packages

♦ +3V Logic Compatibility
