ADS1246IPWR 24-Bit Analog-to-Digital Converter for Sensor Measurement
The ADS1246IPWR is a highly-integrated, precision 24-bit analog-to-digital converter (ADC) designed for sensor measurement applications. This device features an onboard low-noise programmable gain amplifier (PGA), a precision delta-sigma (ΔΣ) ADC with single-cycle settling digital filter, and an internal oscillator.
An input multiplexer supports one differential input and includes sensor burn-out detection, voltage bias for thermocouples, system monitoring, and general-purpose digital I/Os.
