Product Summary

The INA105KU 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 differential amplifier is the foundation of many commonly used circuits. The INA105KU provides this precision circuit function without using an expensive precision resistor network. The INA105KU is available in 8-pin plastic DIP, SO-8 surface-mount and TO-99 metal packages. The applications of the INA105KU are: (1)Differentiaamplifier; (2)Instrumentation amplifier building block; (3)Unity-gain inverting amplifier; (4)Gain-of-1/2 amplifier; (5)Noninverting gain-OF-2 amplifier; (6)Average value amplifier; (7)Absolute value amplifier; (8)Summing amplifier; (9)Synchronous demodulator; (10)Current receiver with compliance to rails; (11)4mA TO 20mA transmitter; (12)Voltage-controlled current source; (13)All-pass filters.
