The AD4131-4BCPZ is an ultra-low-power, high-accuracy measurement solution for low-bandwidth battery-powered applications. The fully integrated analogue front end (AFE) includes a multiplexer (up to 8 single-ended or 4 differential inputs), programmable gain amplifier (PGA), 16-bit sigma-delta (Σ-Δ) analogue-to-digital converter (ADC), on-chip references and oscillators, optional filter options, flexible sequencers, transducer bias and excitation options, diagnostics, and additional features to improve battery operating life ( duty cycle).
Product Features
Ultra-low current consumption (typical)
32 μA: continuous conversion mode (gain = 128)
5 μA: Duty cycle mode (ratio = 1/16)
0.5 μA: Standby mode
0.1 μA: Power-down mode
Built-in functions for system-level power saving
Current saving duty cycle: 1/4 or 1/16
