Product Overview
The AD5941BCPZ-RL7 is an ultra-low power, high-precision electrochemical AFE from Analog Devices, optimized for portable & wearable sensing devices. This single-chip IC integrates all circuits needed for EIS, cyclic voltammetry and amperometric testing, including a 16-bit 800kSPS SAR ADC, waveform generator and dual low-noise potentiostat channels. Built-in hardware accelerators offload filtering work from host MCUs to cut system power draw. Packaged in compact LFCSP-48, it delivers stable, repeatable measurement performance while shrinking PCB footprint for medical patches, gas detectors and bio-sensing instruments.
Core Advantages
Comprehensive Electrochemical Integration
Consolidates a fast 16-bit SAR ADC, dual programmable potentiostat loops, a TIA (Transimpedance Amplifier), and hardware accelerators onto a single die, replacing multiple discrete precision op-amps and data converters.
Integrated High-Precision EIS Engine
Features an onboard digital waveform generator and hardware complex frequency tracking (DFT), allowing highly accurate Electrochemical Impedance Spectroscopy mapping up to 200 kHz to easily identify sensor aging or degradation.
Ultra-Low Active Power Architecture
Engineered with dynamic power-down modes and low-power bias channels, drawing negligible operating currents to effectively maximize the battery lifespans of remote gas monitors and wearable wellness trackers.
Excellent System Isolation & Rejection
Utilizes advanced high-input impedance differential tracking nodes that inherently cancel ambient thermal drifts and local high-frequency power rail noise, preserving absolute micro-ampere level signal fidelity.

Frequently Asked Questions
Q1: Is your currently available stock of the AD5941BCPZ-RL7 component fully original and authentic?
A: Yes, we guarantee that all AD5941BCPZ-RL7 AFE chips in our inventory are 100% brand-new, factory-original products from Analog Devices Inc., kept inside temperature-controlled and anti-static ESD shielding pipelines.
Q2: What unique analytical capabilities does the integrated EIS engine offer?
A: The Electrochemical Impedance Spectroscopy (EIS) engine lets the device sweep a multi-frequency AC signal into a chemical sensor or biological tissue up to 200 kHz. The internal digital processor calculates real and imaginary impedance values directly, allowing real-time degradation checks or body tissue characterizations without heavy host MCU math overhead.
Q3: What does the suffix “-RL7” mean in the part number?
A: The “-RL7” suffix designates the specific factory packaging format, signifying that the components are delivered on a 7-inch standard tape and reel containing a defined volume of parts formatted for high-speed automated SMD pick-and-place assembly lines.
Q4: How can our engineering development group request register initialization scripts, evaluation board files, or ask for tiered volume discount quotes?
A: Please complete our Quick Inquiry web form on this page with details about your processing parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
