Product Code : ADS1148

Product Specification

Description

The ADS1146, ADS1147, and ADS1148 are highly-integrated, precision, 16-bit analog-to-digital converters (ADCs). The ADS1146/7/8 feature an onboard, low-noise, programmable gain amplifier (PGA), a precision delta-sigma ADC with a single-cycle settling digital filter, and an internal oscillator. The ADS1147 and ADS1148 also provide a built-in voltage reference with 10mA output capacity, and two matched programmable current digital-to-analog converters (DACs). The ADS1146/7/8 provide a complete front-end solution for temperature sensor applications including thermal couples, thermistors, and resistance temperature detectors (RTDs).

An input multiplexer supports four differential inputs for the ADS1148, two for the ADS1147, and one for the ADS1146.
