Highly integrated: features a low-noise 24-bit Σ-Δ ADC, programmable gain instrumentation amplifier, precision voltage reference, and matched programmable excitation current sources.

Low noise: typical RMS noise of 40 nV at a data update rate of 4.17 Hz, allowing direct acquisition of weak differential signals at maximum gain (64×).

Flexible configuration:

• 3 differential analog input channels

• Programmable output data rate: 4.17 Hz to 470 Hz

• Compatible with SPI, QSPI, MICROWIRE, DSP and other serial interfaces
