The AD4114BCPZ device is a single-supply, multichannel, 31.25 kSPS, 24-bit Σ-∆ ADC with ±10 V input.


Features:

24-bit ADC with integrated AFE

Fast and flexible output rates: 1.25 SPS to 31.25 kSPS

Channel scan data rate of 6.21 kSPS per channel (161μs setup time)

There are 17.3 noise-free bits per channel at 1007 SPS

At 20 SPS, the 50 Hz and 60 Hz common mode rejection ratio for each channel is 120 dB

±10 V input, 8 differential or 16 single-ended

VIN pin absolute maximum rating: ± 65 V

Absolute input pin voltage up to ±20 V

Minimum 1MΩ impedance

At 25°C, 0.07% TUE

On-chip 2.5V reference voltage source

Initial accuracy of ±0.12% for 25°C, drift ±5 ppm/°C (typical value)

Internal or external clock

Power source

AVDD = 3.0V to 5.5V

IOVDD = 2 V to 5.5 V

Total current consumption: AVDD + IOVDD (IDD) = 3.9 mA

Temperature range: −40°C to +105°C

3-wire or 4-wire serial digital interface (Schmitt flip-flop on SCLK)

Compatible with SPI, QSPI, MICROWIRE and DSP


Description:

The AD4114BCPZ is a low-power, low-noise, 24-bit sigm-∆ analog-to-digital converter (ADC) that integrates an analog front end (AFE) to support a fully differential or single-ended high-impedance (≥1 MΩ), bipolar ±10 V input. The device integrates key analog and digital signal conditioning modules and can be configured with eight separate Settings for each analog input channel used. For fully established data, the AD4114 has a maximum channel scan rate of 6.21 kSPS(161 μs).
