Analog Devices Inc. (Wilmington, MA) introduced its new AD8225 instrumentation amplifier that guarantees a minimum CMR of 80dB at frequencies up to 10kHz, which enables the AD8225 to extract low-level differential signals in the presence of high common-mode voltage levels, even at low supply voltages. Applications include ECGs, respiration monitors, portable defibrillators, pacemaker monitors, vital sign monitors and surgical support equipment.
The AD8225 features a 900kHz bandwidth, a 5V/µsec (minimum) slew rate, 80dB (minimum) CMR to 10kHz, a 5ppm/degree C (maximum) gain drift, 150µV (maximum) input offset voltage, 2µV/degree C (maximu) offset drift, and a 1.2nA (maximum) input bias current.
The AD8225 is packaged in an eight-lead SOIC and is rated to work over the industrial temperature range of -40 to +85 degrees C. Samples and production volumes are available now. The AD8225 is priced at $2.95 per unit in 1,000-piece quantities.
