APPLICATION CIRCUITS
Medical ECG Applications
Figure 9 shows the INA321 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
Ω
resistors. This potential, through a buffer, provides an
optional right leg drive. Filtering can be modified to suit
application needs by changing the capacitor value of the
output filter.
Low-Power, Single-Supply Data Acquisition
Systems
Refer to Figure 5 to see the INA321 configured to drive an
ADS7818. Functioning at frequencies of up to 500kHz, the
INA321 is ideal for low-power data acquisition.
