AD8233ACBZ-R7

Specialized ICS Overview

The AD8233ACBZ-R7 is a fully integrated single-lead ECG front end designed for wearable and portable health monitoring applications. It features a low quiescent supply current of 50 µA (typical) and operates on a single supply voltage ranging from 1.7 V to 3.5 V. The device provides high signal gain (G = 100) with DC blocking capabilities, accepting up to ±300 mV of half-cell potential. Key electrical parameters include an 80 dB common-mode rejection ratio (DC to 60 Hz), 8 kV HBM ESD rating, and rail-to-rail output. It incorporates a two-pole adjustable high-pass filter and a three-pole adjustable low-pass filter using an uncommitted op amp.

• Wearable and remote health monitors
• Biopotential signal acquisition such as EMG

Specialized ICS Procurement Notes

Verify the package type matches the requirement, as the AD8233 is available in a 2 mm × 1.7 mm WLCSP package. Confirm the suffix -R7 indicates tape and reel packaging. Ensure the operating temperature range (-40°C to +85°C) aligns with the specific application environment requirements.
