ADI ADA4897-1SRJZ-EPR7

The ADA4896-2/ADA4897-1/ADA4897-2 are unity-gain stable, low noise, rail-to-rail output, high speed voltage feedback amplifiers that have a quiescent current of 3 mA. With a 1/f noise of 2.4 nV/√Hz at 10 Hz and a spurious-free dynamic range of -80 dBc at 2 MHz the ADA4896-2/ADA4897-1/ADA4897-2 are ideal solutions in a variety of applications, including ultrasound, low noise preamplifiers, and drivers of high performance ADCs. The proprietary next-generation SiGe bipolar process and innovative architecture enable such high performance amplifiers. The ADA4896-2/ADA4897-1/ADA4897-2 have 230 MHz bandwidth, 120 V/μs slew rate, and settle to 0.1% in 45 ns. With a wide supply voltage range of 3 V to 10 V, the ADA4896-2/ADA4897-1/ADA4897-2 are ideal candidates for systems that require high dynamic range, precision, low power, and high 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 ADA4897-2 is available in a 10-lead MSOP package. The ADA4896-2/ADA4897-1/ADA4897-2 operate over the extended industrial temperature range of -40°C to +125°C
