Information

The CS5451A is a highly integrated delta-sigma (DS) analog-to-digital converter (ADC) developed for the power measurement industry. The CS5451A combines six DS ADCs, decimation filters, and a serial interface on a single chip. The CS5451A interfaces directly to a current transformer or shunt to measure current, and to a resistive divider or transformer to measure voltage. The product features a serial interface for communication with a microcontroller or DSP. The product is initialized and fully functional upon reset, and includes a voltage reference.

Key Features

  • Synchronous Sampling
  • On-chip 1.2 V Reference (25 ppm/°C typ.)
  • Power Supply Configurations:
    • VA+ = +3 V; VA- = -2 V; VD+ = +3 V
    • Supply Tolerances: ±10%
  • Power Consumption
    • 23 mW Typical at VD+ = +3 V
  • Simple Four-wire Serial Interface
  • Charge pump driver output generates negative power supply.
  • Ground-referenced Bipolar Inputs
