ADS1246IPW Description

Short technical summary and product information.

The ADS1246IPW is a precision 24-bit sigma-delta ADC designed for sensor measurement applications. It integrates a low-noise programmable gain amplifier (PGA) and supports both differential and single-ended inputs via a single input channel. The device achieves a sampling rate of up to 2 kSPS with single-cycle settling, making it suitable for multiplexed systems.

 

Operating from analog and digital supplies of 2.7V to 5.25V, the ADC consumes low power. It includes an internal 2.048V reference with low drift of 10 ppm/°C (max) and supports external reference for increased flexibility. The SPI-compatible digital interface simplifies connection to microcontrollers. Additional features include a temperature sensor and sensor burn-out detection.

 

Housed in a 16-pin TSSOP package, the ADS1246IPW is surface-mountable and operates over the industrial temperature range of -40°C to 105°C. The device is RoHS3 compliant and has an MSL rating of Level-1 (unlimited). It is ideal for temperature sensors (RTDs, thermocouples, thermistors), pressure measurements, flow meters, and industrial process control.
