Technical Support www.analog.com FEATURES Low wideband noise 1 nV/√Hz 2.6 pA/√Hz Low 1/f noise: 2 nV/√Hz at 10 Hz Low distortion (SFDR): −96 dBc at 100 kHz, V OUT = 2 V p-p Low power: 3 mA per amplifier Low input offset voltage: 350 µV maximum High speed 236 MHz, −3 dB bandwidth (G = +10) 943 V/µs slew rate 22 ns settling time to 0.1% Rail-to-rail output Wide supply range: 3 V to 10 V Disable feature APPLICATIONS Low noise preamplifier Ultrasound amplifiers PLL loop filters High performance ADC drivers DAC buffers GENERAL DESCRIPTION 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.
