Mikroe GainAMP 3 Click

Mikroe GainAMP 3 Click features the Analog Devices ADA4254 zero drift, high voltage, programmable gain instrumentation amplifier. It features 12 binary weighted gains and three scaling gain options resulting in 36 possible gain settings. It comes with an input multiplexer providing ±60V protection to the high impedance inputs of the amplifier. The GainAMP 3 has an excitation current source output available to bias sensors like resistance temperature detectors (RTDs). The ADA4254 zero-drift amplifier topology self-calibrates DC errors and low-frequency noise. This achieves excellent DC precision over the entire specified temperature range, maximizing dynamic range, and significantly reducing calibration requirements in many applications.
