Low Power, 1 nV/√Hz, G ≥ 10 Stable, Rail-to-Rail Output Amplifier
Manufactured by:

Product Details

The ADA4895-2 is a dual, high speed voltage feedback amplifier that is gain ≥ 10 stable with low input noise, rail-to-rail output, and quiescent current of 3 mA per amplifier. With a 1/f noise of 2 nV/√Hz at 10 Hz and a spurious-free dynamic range of −72 dBc at 2 MHz, the ADA4895-2 is 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 this high performance amplifier.

The ADA4895-2 has a large signal bandwidth of 146 MHz at a gain of +10 with a slew rate of 943 V/μs, and settles to 0.1% in 22 ns. The wide supply voltage range (3 V to 10 V) of the ADA4895-2 makes this amplifier an ideal candidate for systems that require high dynamic range, high gain, precision, and high speed.

The ADA4895-2 is available in a 10-lead MSOP package and operates over the extended industrial temperature range of −40°C to +125°C.

Applications

  • Low noise preamplifier
  • Ultrasound amplifiers
  • PLL loop filters

Product Details

The ADA4895-2ARM-EBZ evaluation board aids in the testing of the ADA4897-2 a dual high speed low noise low power amplifier. ADA4895-2ARM-EBZ is a bare board, that is there are no components soldered to the board. This enables users to customize the circuit and quickly prototype a variety of low noise, low power amplifier circuits, which minimizes risk and reduces time to market.
