Description
The CS5451A is a highly integrated Delta-Sigma (
Σ)
Analog-to-Digital Converter (ADC) developed for the
Power Measurement Industry. The CS5451A combines
six
Σ
ADCs, decimation filters, and a serial interface on
a single chip. The CS5451A interfaces directly to a cur-
rent transformer or shunt to measure current, and
resistive divider or transformer to measure voltage. The
product features a serial interface for communication
with a micro-controller or DSP. The product is initialized
and fully functional upon reset, and includes a Voltage
Reference.
