The ADA4896-2/ADA4897-1 is a unity-gain-stable, low-noise, rail-to-rail output, high-speed voltage-feedback amplifier with a quiescent current of 3 mA, a noise of 2.4 nV/√Hz (10 Hz) of 1/f noise, and a stray-free dynamic range of -80 dBc (2 MHz), making it an ideal solution for a wide range of applications such as ultrasonic, low-noise preamplifiers, and high-performance ADC drivers. It is Analog Devices' proprietary next-generation SiGe bipolar process and innovative construction that make 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 is ideal for systems that require high dynamic range, accuracy, and speed.
The ADA4896-2 is available in 8-pin LFCSP and 8-pin MSOP packages. The ADA4897-1 is available in 8-pin SOIC and 6-pin SOT-23 packages. Both ADA4896-2 and ADA4897-1 have an operating temperature range of −40°C to +125°C wide industrial temperature range.
