AD8225

The AD8225 is an instrumentation amplifier with a fixed gain f 5, which sets new standards of performance. The superior MRR of the AD8225 enables rejection of high frequency ommon-mode voltage (80 dB Min @ 10 kHz). As a result,higher ambient levels of noise from utility lines, industrial quipment, and other radiating sources are rejected. Extended MV range enables the AD8225 to extract low level differential ignals in the presence of high common-mode dc voltage levels ven at low supply voltages.

Ambient electrical noise from utility lines is present at 60 Hz nd harmonic frequencies. Power systems operating at 400 Hz reate high noise environments in aircraft instrument clusters. ood CMRR performance over frequency is necessary if power ystem generated noise is to be rejected. The dc to 10 kHz MRR performance of the AD8225 rejects noise from utility ystems, motors, and repair equipment on factory floors, switching ower supplies, and medical equipment.

Low input bias currents combined with a high slew rate of 5 V/s ake the AD8225 ideally suited for multiplexed applications.The AD8225 provides excellent dc precision, with maximum nput offset voltage of 150 V and drift of 2 V/°C. Gain drift is   ppm/°C or less.

Operating on either single or dual supplies, the fixed gain of 5 nd wide input common-mode voltage range make the AD8225 ell suited for patient monitoring applications.

The AD8225 is packaged in an 8-lead SOIC package and is pecified over the standard industrial temperature range, 40°Cto +85°C.
