Product Overview

The ADS1248IPW is a 24-bit Analogue-to-digital Converter features an onboard, low-noise, programmable gain amplifier (PGA), a precision delta-sigma (ΔΣ) ADC with a single-cycle settling digital filter and an internal oscillator. The ADS1248 also provides a built-in, very low drift voltage reference with 10mA output capacity and two matched programmable current digital-to-analogue converters (DACs). The ADC provides a complete front-end solution for temperature sensor applications including thermal couples, thermistors and RTDs. An input multiplexer supports four differential inputs. In addition, the multiplexer has a sensor burnout detect, voltage bias for thermocouples, system monitoring and general-purpose digital I/Os. The onboard, low-noise PGA provides selectable gains of 1 to 128. The ΔΣ modulator and adjustable digital filter settle in only one cycle, for fast channel cycling when using the input multiplexer and support data rates up to 2kSPS.
  • Single-cycle settling for all data rates
  • 4 Differential/7 single-ended inputs
  • Matched current source DACs
  • 10ppm/°C Maximum very low drift internal voltage reference
  • Sensor burnout detection
  • 4/8 General-purpose I/Os
  • Internal temperature sensor
  • Power supply and VREF monitoring
  • Self and system calibration
  • Green product and no Sb/Br
ESD sensitive device, take proper precaution while handling the device.
