  • Output data rate: 1.17 SPS to 2.4 kSPS
  • Operates from 1.71 V to 3.6 V single supply or ±1.8 V split supplies
  • Band gap reference with 15 ppm/°C maximum drift
  • PGA with rail-to-rail analog input
  • Adaptable sensor interfacing functionality
  • Matched programmable excitation currents for RTDs
  • On-chip bias voltage generator for thermocouples
  • Low-side power switch for bridge transducers
  • Sensor open wire detection
  • Internal temperature sensor and oscillator
  • Self and system calibration
  • Flexible filter
  • Simultaneous 50 Hz/60 Hz rejection (on selected filter options)
  • General-purpose outputs
  • Diagnostic functionality
  • Crosspoint multiplexed inputs
  • 8 differential/16 pseudodifferential inputs
  • 5 MHz SPI (3-wire or 4-wire)
  • Available in 35-ball, 2.7 mm × 3.56 mm WLCSP and 32-lead, 5 mm × 5 mm LFCSP
  • Temperature range: -40°C to +105°C (WLCSP), -40°C to +125°C (LFCSP)
  • AD4131-8 LFCSP pin compatible with AD7124-8 LFCSP
