Use a PGIA to avoid getting burned by switch parasitics

Instrumentation Amplifiers (In-Amps) with programmable gain are typically used to maximise dynamic range in precision sensor measurements. Most in-amps use an external gain resistor, Rg, to set the gain, so the desired gains can be achieved by multiplexing a set of resistors. Three major issues must be considered before implementing a system this way, however: supply limitations, switch capacitance and on-resistance. By Scott Hunt, Product Applications Engineer, Analog Devices.
