Analog to Digital Converters

ADS1148IPW Description

The ADS1148IPW from Texas Instruments is a high-precision, 16-bit, delta-sigma analog-to-digital converter (ADC) designed for low-power, high-accuracy measurement applications. It integrates a programmable gain amplifier (PGA) with gains from 1 to 128, enabling direct interfacing with low-level sensor signals. The device supports 2k samples per second (SPS) and operates with both differential and single-ended inputs, offering flexibility for diverse signal conditioning requirements. With 4 or 7 configurable inputs, it accommodates multi-channel systems while maintaining excellent noise performance. The ADC features SPI-compatible serial interface for seamless communication with microcontrollers or DSPs. Its dual-supply operation (2.7V to 5.25V) ensures compatibility with a wide range of systems, making it ideal for industrial, medical, and instrumentation applications.
