More Information

The ADS1148-Q1 is a highly-integrated, precision, 16-bit analog-to-digital converter (ADC) that includes many integrated features to reduce system cost and component count for sensor measurement applications. The device features a low-noise, programmable gain amplifier (PGA), a precision delta-sigma (ΔΣ) ADC with a single-cycle settling digital filter, and an internal oscillator. The ADS1148-Q1 integrates a low-drift voltage reference, and two matched programmable excitation current sources (IDACs).
