Product details
Overview
AD4114BCPZ-RL7 from Analog Devices is a 24-bit sigma-delta ADC with integrated analog front end (AFE), supporting up to 8 differential or 16 single-ended ±10 V inputs, 31.25 kSPS maximum output data rate, 17.3 noise-free bits at 1007 SPS, and on-chip 2.5 V reference with ±0.12% initial accuracy - deployed in industrial PLC analog input modules for high-accuracy sensor signal acquisition.
For engineers reviewing the AD4114BCPZ-RL7 datasheet, AD4114BCPZ-RL7 pinout, AD4114BCPZ-RL7 application, or AD4114BCPZ-RL7 equivalent, key selection criteria include bipolar ±10 V input range, 120 dB 50/60 Hz rejection at 20 SPS, 1 MΩ input impedance, single-supply operation (AVDD 3.0–5.5 V), and 40-lead LFCSP package compatibility with isolated industrial I/O designs.
Technical Context
The AD4114BCPZ-RL7 implements a proprietary iPassives®-enhanced sigma-delta modulator with sinc5 + sinc1 and sinc3 digital filter options, enabling simultaneous 50 Hz and 60 Hz rejection at 27.27 SPS. Its automatic channel sequencer supports up to 16 configurable input channels with individual setup registers for gain, offset, and filter per channel.
It integrates dual LDOs (1.8 V analog/digital rails), internal 2.5 V reference with ±5 ppm/°C drift, and Schmitt-triggered SPI-compatible serial interface (3-/4-wire) operating up to 2.048 MHz clock. Absolute input pin voltage tolerance reaches ±20 V (AVDD ≥ 4.75 V), with VINx absolute max rating of ±65 V relative to AVSS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 24-bit no missing codes; delivers 17.3 noise-free bits at 1007 SPS for high dynamic range in low-frequency measurement. |
| Input Range | ±10 V differential or single-ended; supports industrial sensor outputs (e.g., 4–20 mA with precision shunt) without external scaling. |
| ODR Range | 1.25 SPS to 31.25 kSPS; enables flexible trade-off between noise performance and throughput across multi-channel scans. |
| CMRR | 120 dB at 50/60 Hz (20 SPS); eliminates mains interference in factory-floor environments without external notch filters. |
| Reference | On-chip 2.5 V band gap with ±0.12% initial accuracy and ±5 ppm/°C drift; reduces BOM count and improves system-level TUE stability. |
| Power | Total IDD = 3.9 mA (AVDD + IOVDD); enables low-power operation in thermally constrained PLC backplanes. |
| Temp Range | −40°C to +105°C; qualified for extended industrial ambient conditions in control cabinet deployments. |
Pinout & Package
The AD4114BCPZ-RL7 is housed in a 40-lead, 6 mm × 6 mm LFCSP package with exposed thermal pad soldered to AVSS. Pin functions support full analog input multiplexing, reference buffering, crystal/clock interface, and four GPIO/GPO pins for system-level control signaling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN0–VIN15 | Analog Input | 16 single-ended or 8 differential inputs; each configurable independently for range, filter, and settling time. |
| VINCOM | Common Reference | Single-ended input reference node; must be connected to analog ground for proper biasing. |
| REF+, REF− | Reference Interface | Accept external reference (1–AVDD V) or connect to internal REFOUT; selectable per channel via setup register. |
| DOUT/RDY | Dual-function I/O | Serial data output during read cycles; active-low data-ready interrupt when CS is low and no read in progress. |
| GPIO0, GPIO1, GPO2, GPO3 | General-Purpose I/O | Configurable as inputs or outputs referenced to AVDD/AVSS; usable for status indication or external multiplexer control. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated AFE with iPassives® | Factory-calibrated 0.07% total unadjusted error at 25°C eliminates need for system-level calibration in most PLC applications. |
| Flexible Digital Filtering | Sinc5+sinc1 and sinc3 modes allow simultaneous 50/60 Hz rejection and single-cycle settling for fast channel scanning (6.21 kSPS). |
| High-Voltage Input Tolerance | ±65 V absolute pin rating and ±20 V operational input range enable robustness against field wiring transients and misconnections. |
| Galvanic Isolation Support | Single-supply operation (AVDD only) and independent IOVDD simplify integration with isolated power domains and digital isolators. |
| Embedded Temperature Sensor | ±2°C accuracy after user calibration at 25°C; provides on-chip thermal monitoring without external components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision, multi-channel sigma-delta ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD4112BCPZ-RL7 | 8-channel version (vs. 16-channel); identical architecture, same 24-bit resolution, ±10 V inputs, and 31.25 kSPS ODR. | Limited to 8 differential inputs; suitable for lower-channel-count modules where board space or cost is constrained. | Select AD4112BCPZ-RL7 when fewer than 8 differential inputs are required and footprint reduction is prioritized. |
| ADS131M08IPBSR | TI 24-bit delta-sigma ADC with 8-channel differential inputs, ±10 V range, but no integrated reference; requires external 2.5 V reference and higher supply current (5.5 mA). | Lacks on-chip reference and iPassives® trimming; demands additional passive components and calibration effort for equivalent TUE. | Choose ADS131M08IPBSR only if TI ecosystem alignment or specific timing features (e.g., faster wake-up) outweigh added design complexity. |
Compared with AD4112BCPZ-RL7, the AD4114BCPZ-RL7 offers double the channel count in the same LFCSP package, enabling higher I/O density without layout change; versus ADS131M08IPBSR, it delivers lower system-level TUE and reduced BOM count due to integrated reference and factory calibration.

FAQ
What is the maximum channel scan rate of the AD4114BCPZ-RL7?
The AD4114BCPZ-RL7 achieves a maximum channel scan rate of 6.21 kSPS per channel with 161 µs settling time for fully settled data. This is enabled by its automatic channel sequencer and optimized sinc5 + sinc1 digital filter configuration, allowing rapid cycling across all 16 single-ended or 8 differential inputs while maintaining specified accuracy and noise performance in the AD4114BCPZ-RL7.
Does the AD4114BCPZ-RL7 require an external reference voltage?
No, the AD4114BCPZ-RL7 includes an integrated 2.5 V band gap reference with ±0.12% initial accuracy and ±5 ppm/°C typical drift, buffered and available at the REFOUT pin. External reference use is optional and supported via REF+ and REF− pins, but the AD4114BCPZ-RL7 delivers full specified performance using its internal reference, reducing component count and board space.
What is the absolute maximum input voltage rating for the AD4114BCPZ-RL7?
The AD4114BCPZ-RL7 has an absolute maximum rating of ±65 V on any VINx pin relative to AVSS, and a functional input voltage range of ±20 V (at AVDD ≥ 4.75 V). These ratings provide robust protection against field-induced transients and wiring faults, making the AD4114BCPZ-RL7 suitable for harsh industrial environments without external clamping circuitry.
Can the AD4114BCPZ-RL7 operate with a single supply only?
Yes, the AD4114BCPZ-RL7 operates from a single analog supply (AVDD = 3.0 V to 5.5 V) and a separate digital I/O supply (IOVDD = 2 V to 5.5 V), enabling true single-supply system integration. Its architecture supports galvanically isolated designs where AVDD and IOVDD can be independently powered, and the AD4114BCPZ-RL7 maintains full specification compliance across this supply range.
How many general-purpose I/O pins does the AD4114BCPZ-RL7 provide?
The AD4114BCPZ-RL7 provides four general-purpose I/O pins: GPIO0 and GPIO1 (bidirectional, AVDD/AVSS referenced), and GPO2 and GPO3 (output-only, AVDD/AVSS referenced). These pins support system-level functions such as external multiplexer control, status signaling, or synchronization - configurable via the GPIO Configuration Register in the AD4114BCPZ-RL7's register map.
