The CS5451A is a highly integrated, Delta Sigma analog/digital converter (ADC) developed for the power measurement industry. The CS5451A combines six Delta Sigma 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.
Features
16-bit, fourth-order modulator
Synchronous sampling
Simple 4-wire serial interface
Charge pump driver output generates negative power supply
Ground-referenced bipolar inputs
Power supply configurations
VA+ = 3 V; VA- = -2 V; VD+ = 3 V
Supply tolerances ±10%
On-chip 1.2 V reference (25 ppm/°C typ.)
Low-power consumption
Package: 28-pin SSOP; lead-free assembly
