Microchip Technology Inc. announced its first high-accuracy, stand-alone six-channel analog front end
(AFE) for three-phase energy metering.
MCP3903 AFE
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
Extended Temperature Range: -40°C to +125°C
28-pin SSOP package
