Rochester Electronics Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps AD8229HDZ

The AD8229HDZ is an ultralow noise instrumentation amplifier designed for high-temperature applications, capable of operating up to 210¬8C. It features a low input noise of 1 nV/,àöHz and an output noise of 45 nV/,àöHz, making it suitable for measuring small signals in the presence of large common-mode voltages. The amplifier offers a high common-mode rejection ratio (CMRR) of 126 dB at a gain of 100, which increases with gain, ensuring minimal interference from unwanted signals. With a bandwidth of 15 MHz at a gain of 1 and 1.2 MHz at a gain of 100, the AD8229HDZ is one of the fastest instrumentation amplifiers available. It has a slew rate of 22 V/Oºs and excellent total harmonic distortion performance of ,àí130 dBc at 1 kHz with a gain of 1. The gain can be set from 1 to 1000 using a single resistor, and it operates on a dual supply voltage ranging from ¬±4 V to ¬±17 V. The device is packaged in an 8-lead side-brazed ceramic dual in-line package (SBDIP) and is suitable for applications such as down-hole instrumentation, harsh environment data acquisition, exhaust gas measurements, and vibration analysis. The AD8229HDZ is designed to meet the demands of high-performance applications while maintaining reliability in extreme conditions.
