Product details
Overview
AD4130-4BCPZ-RL7 from Analog Devices is a 24-bit sigma-delta ADC with integrated PGA, FIFO, and sensor biasing circuitry, delivering 25 nV rms noise at 1.17 SPS (gain = 128), 32 µA continuous current draw, and 4 differential / 8 pseudo-differential inputs. It targets ultra-low-power battery-operated measurement systems such as wireless sensor nodes and portable instrumentation.
For engineers reviewing the AD4130-4BCPZ-RL7 datasheet, AD4130-4BCPZ-RL7 pinout, AD4130-4BCPZ-RL7 application, or AD4130-4BCPZ-RL7 equivalent, key selection criteria include its 1.71 V minimum supply, duty-cycling capability (1/16 ratio), on-chip 15 ppm/°C reference, matched RTD excitation currents (100 nA–200 µA), and autonomous FIFO interrupt functionality for host processor offload.
Technical Context
The AD4130-4BCPZ-RL7 integrates a 24-bit Σ-Δ ADC core with programmable gain amplifier (1× to 128×), crosspoint multiplexer supporting 4 differential or 8 pseudo-differential channels, and configurable digital filters including Sinc3/Sinc4 with simultaneous 50 Hz/60 Hz rejection. Its smart sequencer enables per-channel configuration of gain, ODR, filter, and reference source across 16 channels.
It features embedded diagnostics including burnout current-based open-wire detection, analog input overvoltage/undervoltage monitoring, reference detection, CRC-protected SPI, and internal temperature sensing. Power management includes four modes: 32 µA continuous, 5 µA duty-cycled (1/16), 0.5 µA standby, and 0.1 µA power-down - all supported by a single 1.71–3.6 V supply.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7124-4BRUZ | Same 32-lead LFCSP footprint and pinout; higher 385 µA typical current in continuous mode; no duty cycling or FIFO | Targeted at mains-powered or higher-throughput systems where power is less constrained | Select AD7124-4BRUZ when higher ODR (up to 19.2 kSPS) and lower INL (±4 ppm vs. ±15 ppm) are prioritized over ultra-low power |
| ADS1220IPWR | 8-pin TSSOP; 1.8 V min supply; 250 µA typical current; no integrated excitation or FIFO; SPI interface only | Cost-sensitive, space-constrained designs with simpler sensor types (e.g., single RTD) | Select ADS1220IPWR when board area and BOM cost outweigh need for autonomous operation and multi-sensor biasing |
Compared with AD4130-4BCPZ-RL7, AD7124-4BRUZ offers higher speed and precision but lacks power-saving features essential for battery life, while ADS1220IPWR reduces size and cost but requires external biasing and increases host firmware complexity.

FAQ
What is the minimum supply voltage required for AD4130-4BCPZ-RL7 to operate correctly?
The AD4130-4BCPZ-RL7 operates down to 1.71 V on its AVDD analog supply rail, enabling extended battery life in coin-cell applications. At this voltage, the internal reference remains stable, PGA functionality is preserved, and the ADC maintains full 24-bit resolution with specified noise performance. Operation below 1.71 V may cause reference instability or conversion errors and is outside guaranteed specifications.
Does AD4130-4BCPZ-RL7 support simultaneous 50 Hz and 60 Hz line frequency rejection?
Yes, AD4130-4BCPZ-RL7 supports simultaneous 50 Hz and 60 Hz rejection using its Sinc3 + REJ60 filter configuration or specific post-filter modes. When configured with FS = 48 (50 SPS), it achieves ≥115 dB rejection at both frequencies. This capability is verified in the datasheet's Table 6 and enables robust operation in globally deployed equipment without manual filter reconfiguration.
How does the FIFO in AD4130-4BCPZ-RL7 reduce host processor load?
The AD4130-4BCPZ-RL7's 256-deep FIFO buffers conversion results autonomously, allowing the host microcontroller to remain in deep sleep until a programmable threshold (e.g., 64 samples) is reached. This eliminates polling overhead and frequent wake-ups, reducing system-level power consumption significantly - especially critical in battery-powered sensor nodes where MCU activity dominates total energy use.
Can AD4130-4BCPZ-RL7 directly interface with 4-wire RTDs?
Yes, AD4130-4BCPZ-RL7 supports direct 4-wire RTD interfacing using its matched IEXC0 and IEXC1 excitation current sources (±0.5% matching) and dedicated AIN pins. The device provides programmable currents from 100 nA to 200 µA, low-drift PGA gain, and built-in open-wire detection via burnout currents - eliminating need for external current sources, op-amps, or discrete diagnostics circuitry.
Is AD4130-4BCPZ-RL7 pin-compatible with any other Analog Devices ADCs?
Yes, AD4130-4BCPZ-RL7 in the 32-lead LFCSP package is pin-compatible with AD7124-4 in the same package variant, sharing identical pin assignments for AVDD, DGND, AINx, REFIN, SCLK, DIN, DOUT/RDY, and CS. This enables drop-in migration for designs upgrading from AD7124-4 to leverage AD4130-4BCPZ-RL7's ultra-low power, FIFO, and duty cycling features without PCB revision.
