The ADS1148 from Texas Instruments is a precision 16-bit Analog-to-Digital Converter (ADC) designed for sensor measurement applications. It features a delta-sigma architecture with single-cycle settling, enabling data rates up to 2 kSPS. The device includes an onboard, low-noise programmable gain amplifier (PGA) with selectable gains from 1 to 128.
This ADC supports multiple input configurations, including 4 differential and 7 single-ended inputs, making it versatile for various sensor types. It also incorporates features such as simultaneous 50/60 Hz rejection at 20 SPS, sensor burnout detection, and dual-matched programmable current sources (IDACs). An internal voltage reference and temperature sensor are also integrated.
The ADS1148 operates with analog and digital supply voltages ranging from 2.7V to 5.25V. It communicates via an SPI-compatible serial interface. The device is available in VQFN and TSSOP packages and operates across a wide temperature range of -40°C to 105°C (manufacturer page) or -40°C to 125°C (datasheet).
Key applications include temperature sensor measurements, thermistors, and resistance temperature detectors (RTDs), providing a complete front-end solution for precision measurement systems.
