Description
The CS5451A is a highly integrated delta-sigma (
Σ)
an-
alog-to-digital converter (ADC) developed for the power
measurement industry. The CS5451A combines six
Σ
ADCs, decimation filters, and a serial interface on a sin-
gle chip. The CS5451A interfaces directly to a current
transformer or shunt to measure current, and to a resis-
tive 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.
