ADA4895-2 low-power, 1NV/√Hz, G≥10-stable, rail-to-rail output amplifier
The ADA4895-1 is a G≥10 stable, single-channel, high-speed voltage-feedback amplifier with low input noise, rail-to-rail output, and a quiescent current of 3 mA per amplifier. With a 1/f noise of 2 nV/√ Hz (10 Hz) and a spurious dynamic range of -72 dBc (2 MHz), it is an ideal solution for a wide range of applications such as ultrasonic, low-noise preamplifiers, and high-performance ADC drivers. It is Analog Devices' proprietary next-generation SiGe bipolar process and innovative construction that make such high-performance amplifiers.
The ADA4895-1 has a large signal bandwidth of 146 MHz at a gain of +10, a slew rate of 943 V/μs, and a 0.1% settling time of 22 ns. It has a wide operating voltage range (3 V to 10 V), making it ideal for systems that require high dynamic range, high gain, high accuracy, and high speed.
The ADA4895-1 is available in an 8-pin SOIC package and a 6-pin SOT package with an extended industrial temperature range of −40°C to +125°C.
