Product Summary

The INA105 is a monolithic Gain = 1 differential amplifier consisting of a precision op amp and on-chip metal film resistors. The resistors are laser trimmed for accurate gain and high common-mode rejection. Excellent TCR tracking of the resistors maintains gain accuracy and common-mode rejection over temperature. The applications of the INA105 include differential amplifier, instrumentation amplifier building block, unity-gain inverting amplifier, gain-of-1/2 amplifier, noninverting gain-of-2 amplifier, average value amplifier, absolute value amplifier, summing amplifier, synchronous demodulator, current receiver with compliance to rails, 4ma to 20ma transmitter, voltage-controlled current source and all-pass filters.
