Microchip Technology Inc. announced its first high-accuracy, stand-alone six-channel analog front end (AFE) for three-phase energy metering.
The MCP3903 AFE includes six 16-/24-bit Delta-Sigma analog-to-digital converters (ADCs) and delivers signal-to-noise and distortion (SINAD) of 89 dB (typical) and total harmonic distortion (THD) of -99 dB (typical) .
Additional integrated features include programmable gain amplifiers, a low-drift voltage reference and phase-delay compensation, for a reduced external component count that increases design flexibility and lowers costs. The MCP3903 AFE is intended for the utility and industrial markets, such as in utility meters, power-monitoring devices and instrumentation devices.
Key highlights :
Six simultaneously sampled 16/24-bit resolution delta-sigma A/D converters
91 dB SINAD, -100 dBc THD, 102 dB SFDR
Programmable data rate up to 64 ksps
Internal voltage reference with low drift of 5 ppm/°C
Internal PGAs on each channel with gain of 32 V/V
Phase delay compensation between channels with 1 µs resolution
