The circuit below uses AD620AN instrumentation amp and allows
the use of a single power supply: a 9V battery.
The gain of the AD620AN chip is set by the resistor across the
pins G- and G+, and is given by G = 1+ 49.4kΩ / RG so we
have set the gain to be approximately 50 by setting RG
as 1K. This, coupled with the back end op-amp gain of 24 will
result in a combined gain of 1,200. This...

Q1. You are given a 12 V DC power supply. You are expected to develop a voltage divider to achieve a voltage of nominal 5V value using a pair of resistors from the E 12 range, with the restrition that you are not expected to draw a current of more than 1 mA from the 12 V DC supply i. Develop a simple circuit showing the possible values for each resistor pair, and the range of the DC output possible...
