ADS1148QPWRQ1 General Description

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).

The device offers a fully flexible multiplexer that allows both positive and negative inputs to be selected independently. In addition, the multiplexer integrates sensor burn-out detection, voltage bias for thermocouples, system monitoring, and eight general-purpose digital I/Os (GPIOs). The PGA provides selectable gains up to 128 V/V. These features provide a complete front-end solution for temperature sensor measurement applications, including thermocouples, thermistors, and resistance temperature detectors (RTDs), and other small-signal measurements. The digital filter settles in a single cycle to support fast channel cycling when using the input multiplexer and provides data rates up to 2 kSPS. For data rates of 20 SPS or less, both the 50-Hz and 60-Hz interference are rejected by the filter.
