Low-power sigma-delta analog-to-digital converter provides 16-bit resolution for precision bridge and sensor measurement applications. The device includes three differential analog inputs, an integrated low-noise instrumentation amplifier, and programmable gain from 1 to 128. It operates from a 2.7 V to 5.25 V supply, supports SPI-compatible serial communication, and provides update rates from 4.17 Hz to 470 Hz. The converter is specified for industrial temperature operation and is supplied in a 16-lead TSSOP package.
