Introduction

AI Translation

The AD4129-8 is an ultra-low power, high precision, measurement solution for low bandwidth battery operated applications. The fully integrated analog front end (AFE) includes a multiplexer for up to 16 single-ended or eight differential inputs, programmable gain amplifier (PGA), 16-bit sigma-delta (Σ←Δ) analog-to-digital converter (ADC), on-chip reference.

Features

AI Translation
  • Ultra-low current consumption (typical):
    • 32 µA: continuous conversion mode (gain = 128)
    • 5 µA: duty cycling mode (ratio 1/16)
    • 0.5 µA: standby mode
    • 0.1 µA: power-down mode
  • Built-in features for system level power savings:
    • Current saving duty cycle ratio: 1/4 or 1/16
    • Smart sequencer and per channel configuration minimizes host processor load
    • Deep embedded FIFO minimizes host processor load (depth of 256 samples)
    • Autonomous FIFO interrupt functionality, threshold detection
    • Single supply as low as 1.71 V increasing battery length
  • RMS noise: 25 nV rms at 1.17 SPS (gain = 128) to 48 nV/√Hz
  • Up to 22 noise free bits (gain = 1)
  • 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/℃ 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 options
