Analogue Front End

AD823x Heart Rate Monitor Front End The AD823x devices are integrated signal conditioning blocks for ECG and other biopotential measurement applications. They are 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. • Fully integrated, single-lead electrocardiogram (ECG) front-end • Common-mode rejection ratio: 80dB (dc to 60Hz) • 2- or 3-electrode configurations • High signal gain (G = 100) with dc blocking capabilities • 2-pole adjustable high-pass filter • Accepts up to ±300mV of half cell potential • Fast restore feature improves filter settling • AC/DC leads on/off detection • Right leg drive (RLD) amplifier • Integrated reference buffer generates virtual ground • Uncommitted op amp for optional 3-pole adjustable low-pass filter • Rail-to-Rail output • Internal RFI filter • Shutdown pin • 8kV human body model (HBM) ESD rating • Power supply: +2.0V to +3.5Vdc ( AD8232 ), +1.7V to +3.5Vdc ( AD8233 ) • Quiescent supply current: 170μA ( AD8232 ), 50μA ( AD8233 ) RS Product Codes • 786-3145 AD8232ACPZ-WP Heart Rate Monitor AFE • 130-1032 AD8233ACBZ-R7 Heart Rate Monitor AFE for Wearable Products Analogue Front End (AFE), Analog Devices

MCP3912 Energy Measurement ICs Energy/Power Measurement - Microchip

The ATM90E36A is a high-performance energy metering device for three-phase four-wire (3P4W, Y0) or three-phase three-wire (3P3W, Y or Δ) systems. It is also applicable in Data Acquisition Terminal. With the measurement and Fourier analysis functions, the ATM90E36A can also be used in power monitoring instruments which need to measure voltage, current, THD, DFT, mean power, etc. Poly-phase solutions up to class 0.2 accuracy. 6000:1 dynamic range improves performance and reduces OEM's overall cost of manufacturing and bill of materials. Lowest temperature drift in the industry for this type of device.
