AD8232ACPZ-RL

Specialized ICS Overview

The AD8232ACPZ-RL is a single-lead, integrated signal conditioning block designed for ECG and other biopotential measurement applications. It extracts, amplifies, and filters small biopotential signals in the presence of noisy conditions, such as those created by motion or remote electrode placement. Key specifications include a high signal gain (G = 100) with DC blocking capabilities, an 80 dB common-mode rejection ratio (DC to 60 Hz), and a typical supply current of 170 µA. The device operates on a single supply voltage ranging from 2.0 V to 3.5 V. It features a 2-pole adjustable high-pass filter, an uncommitted op amp used for a 3-pole adjustable low-pass filter, and an integrated right leg drive (RLD) amplifier. The component is housed in a 20-lead, 4 mm × 4 mm LFCSP package.

Specialized ICS Procurement Notes

Verify the 'RL' suffix indicates Tape & Reel packaging when sourcing. Confirm the specific grade (A or W) required for the target operating temperature range, as A grade is specified from 0°C to 70°C while W grade covers -40°C to +105°C. Ensure the order quantity aligns with reel specifications.
