ADA4895-1

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

Product Details

The ADA4895-1 is a single, 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 ADA4895-1 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 ADA4895-1 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 ADA4895-1 is available in a 8-Lead SOIC package and 6-Lead SOT package and operates 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

Product Details

The ADA4895-xxx-EBZ evaluation board aids in the testing of the ADA4895-1 single high speed low noise low power amplifier. The ADA4895-xxx-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, which minimizes risk and reduces time to market.

Used for photodetectors, good performance, no oscillations like other amplifiers.

The reason I order ADA4895 is for its high-speed performance. And yet its high-gain stable criteria seems not fit for high-speed oscillator, especially for sine wave oscillator.

Good CMRR
It is exactly what I looked for: gain of 10 for frequencies DC to 100MHz with high CMRR in whole frequency range. Very usefull information in datasheet about compensation capacitors for equalization of frequency characteristics. It really works like data sheet says.
