MAX132 - 18-Bit ADC with Serial Interface

General Description

The MAX132 is a CMOS, 18-bit plus sign, serial-output, analog-to-digital converter (ADC).

Multi-slope integration provides high-resolution conversions in less time than standard integrating ADCs, allowing operation up to 100 conversions per second.

Key Features

  • o Low Supply Current: 60µA (Normal Operation) 1µA (Sleep-Mode Operation) o ±0.006% FSR Accuracy at 16 Conv/sec o Low Noise: 15µVRMS o Serial I/O Interface with Programmed Output for Mux and PGA o Performs up to 100 Conv/sec o ±2pA Input Current o 50Hz/60Hz Rejection _______________General.
