Gain programmable circuit offers performance & flexibility - 12/24/04 EDN-Design Ideas: (design idea added 12/04) You can use a standard precision instrumentation amplifier, such as the INA118 or AD623, as a gain-programmable amplifier with high accuracy and wide gain range. However, the gain range of such parts is fixed at certain values, limiting their flexibility. To solve the problem, a usual way is to use a gain-adjustable circuit controlled by a microcomputer
