MAX11410

MAX11410 24-Bit Multi-Channel Low-Power 1.9ksps Delta-Sigma ADC with PGA General Description The MAX11410 is a low-power, multi-channel, 24-bit delta-sigma ADC with features and specifications that are optimized for precision sensor measurement. The input section includes a low-noise programmable gain amplifier (PGA) with very high input impedance and available gains from 1x to 128x to optimize the overall dynamic range. Input buffers provide isolation of the signal inputs from the switched-capacitor sampling network when the PGA is not in use, making the ADC easy to drive even with high-impedance sources. Several integrated features simplify precision sensor applications. The programmable matched current sources provide excitation for resistive sensors. An additional current sink and current source aid in detecting broken sensor wires. The 10-channel input multiplexer provides the flexibility needed for complex, multi-sensor measurements.  GPIOs reduce isolation components and ea...
