Description
The MCP3905A/05L/06A devices are energy-metering
ICs designed to support the IEC 62053 international
metering standard specification. They supply a
frequency output proportional to the average active real
power,
proportional to the instantaneous power for meter
calibration. The MCP3905L offers reduced pulse width
of calibration output frequency and mechanical counter
drive for lower power meter designs. They include two
16-bit, Delta-Sigma ADCs for a wide range of I
I
designs. It includes an ultra-low drift voltage reference
with < 15 ppm/°C through a specially designed band
gap temperature curve for the minimum gradient across
the industrial temperature range. A fixed-function DSP
block is on-chip for active real-power calculation. A no-
load threshold block prevents any current creep
measurements. A Power-On Reset (POR) block
restricts
situations. These accurate energy metering ICs with
high field reliability are available in the industry standard
pinout.
