Analog Devices 

Precision Amplifiers (Bandwidth < 50 MHz)

Ultralow Offset Voltage (VOS ≤ 250 µV Max) Amplifiers

AD8597/AD8599: Ultralow Distortion, Ultralow Noise Operational Amplifier

The AD8597 (single) and AD8599 (dual) are very low noise, low distortion operational amplifiers ideal for use as preamplifiers. The low noise of 1.1 nV/√Hz

and low harmonic distortion of −120 dB (or better) at audio bandwidths give the devices the wide dynamic range necessary for preamplifiers in audio,

medical, and instrumentation applications. The excellent slew rate of 14 V/µs and 10 MHz gain bandwidth make them highly suitable for medical

applications. The low distortion and fast settling time make them ideal for buffering of high resolution data converters.

Features

• Low noise: 1.1 nV/√Hz at 1 kHz

• Low distortion: –120 dB THD @ 1 kHz

• Bandwidth: 10 MHz

• Supply current: 4.8 mA/amp typical

• Low offset voltage: 10 µV typical

• CMRR: 120 dB

Applications

• Professional audio preamplifiers

• ATE/precision testers

• Imaging systems

• Medical/physiologic measurements

• Precision data conversion

AD8622: Dual, Low Power, Low Noise, Precision Amplifier

The AD8622 is a dual, precision, rail-to-rail output operational amplifier with a low supply current of only 350 µA maximum over temperature and supply

voltage. It also offers ultralow offset, drift, and voltage noise combined with very low input bias current over the full operating temperature range. It is

perfectly suited for applications where large error sources cannot be tolerated.

Features

• Very low offset voltage: 125 µA maximum

• Supply current: 215 µA/amp typical

• Input bias current: 200 pA maximum

• Low input offset voltage drift: 1.2 µV/°C

maximum

• Very low voltage noise: 11 nV/√Hz

Applications

• Portable precision instrumentation

• Laser diode control loops

• Medical instrumentation

• Strain gage amplifier

• Thermocouple amplifiers
