Description

The AD4114BCPZ is a low-power, 24-bit, sigma-delta (Σ-Δ) ADC from Analog Devices, designed for precision industrial applications. It features four differential/single-ended analog inputs, a built-in PGA (Programmable Gain Amplifier), and on-chip reference buffers.
Key specifications:
- Resolution: 24-bit
- Data Rate: Up to 31.25 kSPS
- Input Range: ±10 V (with internal attenuator)
- Low Power: 1.8 mW at 31.25 kSPS
- Interface: SPI-compatible
The ADC integrates diagnostic functions, including open-circuit detection, and supports 2.5 V to 5.5 V supply operation. It is ideal for process control, PLCs, and sensor interfaces, offering high accuracy with minimal external components.
Package: 32-lead LFCSP (5 mm × 5 mm).
For detailed specs, refer to the datasheet on Analog Devices' website.
