MCP3550 Datasheet (Microchip) - Single-Channel 22-Bit Delta-Sigma ADCs

MCP3550, Single-Channel 22-Bit Delta-Sigma ADCs

The Microchip Technology Inc.

MCP3550/1/3 devices are 2.7V to 5.5V low-power, 22-bit Delta-Sigma Analog-to-Digital Converters (ADCs).

The devices offer output noise as low as 2.5 µVRMS, with a total unadjusted error of 10 ppm.

The family exhibits 6 ppm Integral Non-Linearity (INL) error, 3 µV offset
