Delta-Sigma ADC incorporates low-power architecture.(Microchip Technology Expands Low-Power, 22-Bit Delta-Sigma A/D Converter Family)
Available in 8-pin, 3.1 x 3.1 x 1.18 mm MSOP, 22-bit MCP3550 comes in models that reject noise greater than 120 dB in 50 and 60 Hz line frequencies and offer respective 12.5 and 15 samples/sec sample rates. Integral nonlinearity is [+ or -]2 ppm typ, and output noise is 2.5 [micro]Vrms min. Along with low-current operation of 120 [micro]A typ and power consumption of 0.6 mW max @ 5 V, both versions offer auto calibration and operate over temperature range of -40 to +125[degrees]C.
