High Temperature Analogue OP Amp from Inertial Aerosystems

This precision low power op amp offers very low input offset voltage and drift over an ambient temperature range of -55 to +225۫ C, with a minimum life of 5 years. Built in auto zeroing techniques mean input offset voltage is continuously sampled and compensated.

An internal oscillator and logic provides all necessary auto-zero clock signals, and no external capacitors are needed. The auto-zero clock generator produces a pseudo-random clock frequency operating between 2kHz and 4kHz that effectively 'spreads out the clock noise frequency. This versatile device has high gain, CMRR: 100dB min. It has single 5V supply operation, with 5.0mA maximum supply current.

Ideal where space and weight are at a premium, this product is available in 14 lead DIP package or die configurations.

Prime applications include Aircraft engine electronics, Downhole drilling measurement, Production tools, Strain gauge transducers, RTD temperature sensing and High temperature measurement.
