●GENERAL DESCRIPTION
●The AD8232 is an integrated signal conditioning block for ECG and other biopotential measurement applications. It is designed to extract, amplify, and filter small biopotential signals in the presence of noisy conditions, such as those created by motion or remote electrode placement. This design allows for an ultralow power analog-to-digital converter (ADC) or an embedded microcontroller to acquire the output signal easily.
●FEATURES
●Fully integrated single-lead ECG front end
●Low supply current: 170 µA (typical)

●Two or three electrode configurations
●High signal gain (G = 100) with dc blocking capabilities
●2-pole adjustable high-pass filter
●Accepts up to ±300 mV of half cell potential
●Fast restore feature improves filter settling
●Uncommitted op amp
●3-pole adjustable low-pass filter with adjustable gain
●Leads off detection: ac or dc options
●Integrated right leg drive (RLD) amplifier
●Single-supply operation: 2.0 V to 3.5 V
●Integrated reference buffer generates virtual ground
●Rail-to-rail output

●Shutdown pin
●20-lead 4 mm × 4 mm LFCSP package
●APPLICATIONS
●Fitness and activity heart rate monitors
●Portable ECG
