The ADA4896-2/ADA4897-1 are unity gain stable, low noise, rail-to-rail output, high speed voltage feedback amplifiers that have a quiescent current of 3 mA. With the 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 are an ideal solution in a variety of applications, including ultrasound, low noise preamplifiers, and drivers of high performance ADCs. The Analog Devices, Inc., proprietary next generation SiGe bipolar process and innovative architecture enable such high performance amplifiers.

TheADA4896-2/ADA4897-1 have 230 MHz bandwidth, 120 V/μs slew rate, and settle to 0.1% in 45 ns. With a wide supply voltage range (3 V to 10 V), the ADA4896-2/ADA4897-1 are ideal candidates for systems that require high dynamic range, precision, 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. Both the ADA4896-2 and ADA4897-1 work over the extended industrial temperature range of −40°C to +125°C.

Applications

  • Low noise preamplifier
  • Ultrasound amplifiers PLL loop filters
  • High performance ADC drivers
  • DAC buffers
