ADS1148IRHBT TI Analog Front End | 32-VQFN (5x5) | 16-Bit, 2kSPS, 8-Channel

Product Overview

The ADS1148IRHBT is a precision, 16-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC) from Texas Instruments. It features an integrated programmable gain amplifier (PGA), voltage reference, and an internal oscillator, making it a complete analog front-end for high-resolution measurement applications. Housed in a compact 32-VQFN (5x5 mm) package, it offers 8 differential or 16 single-ended inputs, a maximum data rate of 2 kSPS, and low power consumption (2.3 mW typical). The device is designed for industrial process control, temperature sensing, and portable instrumentation.
