BIOE 415 Lab Report 3 Monday Section Introduction Similar to the protocol(s) in lab 3, this lab focuses on a specific device, known as the  instrumentation amplifier. Several measurements were taken to find the electrical behavior  of an instrumentation amp, the AD622. In order to manipulate the behavior and amplifier  characteristics, a variety of resistors and input voltages were used to discover the effects  and capabilities of the AD622. Methods   (NOT FINISHED – draw in circuit for 3.2 Input Protection) The procedure was obeyed except for the following modifications: 3.1 – The following circuit was constructed to produce a gain of 100 (without load) HAND-DRAWN PICTURE HERE (100 Hz signal, 511 ohm resistor) 3.4 – The potentiometer was not set exactly to 10 kohms, but rather 9.66 kohms. 4 –

Results  3.1 – Gain of 100 – A 511 ohm resistor was used; but since the output voltage was clipped,  the gain could not be accurately determined 3.1.2 Voltage Divider – A gain of 79.2 V/V was calculated at a 100 Hz frequency signal. At a  375 mV input signal an output of 29.7 V was obtained. See Methods 3.1 for the orientation  of these inputs and outputs.
