The ADA4896-2/ADA4897-1 are unity-gain stable, low noise, rail-to-rail output, high speed voltage feedback amplifiers with 3 mA quiescent current, 2.4 nV/√Hz (10 Hz) 1/f noise, and spurious-free dynamic range of -80 dBc (2 MHz), making them ideal solutions for a variety of applications such as ultrasound, low noise preamplifiers, and high performance ADC drivers. It is Analog Devices' proprietary next-generation SiGe bipolar process and innovative architecture that enable such high performance amplifiers.
With a bandwidth of 230 MHz, a slew rate of 120 V/μs, a 0.1% settling time of 45 ns, and a wide operating voltage range (3 V to 10 V), the ADA4896-2/ADA4897-1 are ideal for systems requiring high dynamic range, accuracy, and speed.
The ADA4896-2 is available in 8-lead LFCSP and 8-lead MSOP packages. The ADA4897-1 is available in 8-lead SOIC and 6-lead SOT-23 packages. The ADA4896-2 and ADA4897-1 operate over a wide industrial temperature range of −40°C to +125°C.
