APPLICATION CIRCUITS
MEDICAL ECG APPLICATIONS
Figure 9 shows the INA332 configured to serve as a low-cost
ECG amplifier, suitable for moderate accuracy heart-rate
applications such as fitness equipment. The input signals are
obtained from the left and right arms of the patient. The
common-mode voltage is set by two 2M
resistors. This
potential through a buffer provides optional right leg drive.
Filtering can be modified to suit application needs by chang-
ing the capacitor value of the output filter.
LOW-POWER, SINGLE-SUPPLY DATA
ACQUISITION SYSTEMS
Refer to Figure 4 to see the INA332 configured to drive an
ADS7818. Functioning at frequencies of up to 500kHz, the
INA332 is ideal for low-power data acquisition.
