Ultra-low-noise op amp

28 May 2008 Analogue, Mixed Signal, LSI

Analog Devices introduced the ADA4898 unity gain stable operational amplifier, offering design engineers broadband noise less than 1 nV/rt Hz), 1/f noise of 1,2 nV/rt Hz at 10 Hz, distortion of -110 dBc at 500 kHz, and DC precision that optimises the performance of analog-to-digital converters (ADCs). Particularly suited for 16- and 18-bit systems, the device features high speed with a -3 dB bandwidth of 70 MHz at G=+1 and slew rate of 40 V/μs, providing an optimal combination of amplifier speed and precision. It has a wide supply range from ±5 to ±15 V. Designed to work with Analog Devices' precision data converters, including the AD7631 and AD7634, the ADA4898 is especially suited for radar-based collision avoidance, medical instrumentation and other precision instrumentation applications. The device is available in an 8-lead SOIC (small outline integrated circuit) package and is rated to operate over the extended industrial temperature range of -40°C to +125°C.
