CS5531-AS - 16-bit and 24-bit ADC

General Description

The CS5531/32/33/34 are highly integrated  Analogto-Digital Converters (ADCs) which use charge-balance techniques to achieve 16-bit (CS5531/33) and 24-bit (CS5532/34) performance.

Key Features

  • Chopper-stabilized PGIA (Programmable Gain Instrumentation Amplifier, 1x to 64x).
  • 12 nV/Hz @ 0.1 Hz (No 1/f noise) at 64x.
  • 1200 pA Input Current with Gains >1 Delta-sigma Analog-to-digital Converter.
  • Linearity Error: 0.0007% FS.
  • Noise Free Resolution: Up to 23 bits Two- or Four-channel Differential MUX Scalable Input Span via Calibration.
  • ±5 mV to differential ±2.5V Scalable VREF Input: Up to Analog Supply Simple Three-wire Serial Interface.
