AD8232ACPZ-R7

Specialized ICS Overview

The AD8232ACPZ-R7 is a single-lead, integrated signal conditioning front end designed for ECG and biopotential measurement applications. It extracts, amplifies, and filters weak bio-signals in noisy environments. Key electrical parameters include a typical supply current of 170 µA at 3 V, a fixed gain of 100 V/V with DC blocking, and an 80 dB common-mode rejection ratio (DC to 60 Hz). The device operates on a single supply voltage ranging from 2.0 V to 3.5 V. It features a two-pole adjustable high-pass filter and utilizes an uncommitted operational amplifier to create a three-pole adjustable low-pass filter.

Specialized ICS Feature Summary

• Integrated instrumentation amplifier with 100 V/V gain and DC blocking capabilities
• Built-in right leg drive (RLD) amplifier for improved common-mode rejection
• Leads-off detection supporting both AC and DC modes
• Fast restore circuitry to reduce high-pass filter settling time after signal interruptions

Specialized ICS Applications

• Wearable heart rate monitors
• Portable ECG devices
• Remote health monitoring systems
• Biopotential signal acquisition

Specialized ICS Procurement Notes

Verify the package type matches the required footprint; the datasheet specifies availability in 20-lead LFCSP packages. Confirm the temperature grade aligns with system requirements, as the 'A' suffix indicates an industrial temperature range of -40°C to +85°C. Ensure the ordering suffix '-R7' corresponds to the correct tape and reel quantity.

Specialized ICS Selection Notes

Select this component when a fully integrated, low-power solution for single-lead ECG is required. The internal RLD amplifier simplifies noise reduction compared to discrete designs. Consider the uncommitted op amp for custom low-pass filtering if specific bandwidth constraints exist beyond standard implementations. Verify that the 2.0 V to 3.5 V supply range fits the target battery or power architecture.
