Low-Power, Single-Channel 22-Bit Delta-Sigma ADCs

MCP3550-50 The Microchip Technology Inc. MCP3550 MCP3551 MCP3553 devices are 2.7V to 5.5V low-power, 22-bit Delta-Sigma Ana- log-to-Digital Converters ADCs). The devices offer ( output noise as low as 2.5 , with a total RMS unadjusted error of 10 ppm. The family exhibits 6 ppm Integral Non-Linearity (INL) error, 3 V offset error an less than 2 ppm full-scale error. The MCP3550 MCP3551 MCP3553 devices provide high accuracy and low noise performance for applications where Sensor measurements (such as pressure, temperature and humidity) are performed. With the internal Oscillator and high oversampling rate, minimal external components are required for high-accuracy applications. By Microchip Technology Inc.
