ADA4897-2-KGD 1 nV/√Hz, Low Power, Rail-to-Rail Output Amplifier
●GENERAL DESCRIPTION
■The ADA4897-2-KGD1 is a unity-gain stable, low noise, rail-to-rail output, high speed voltage feedback amplifier that has a quiescent current of 3 mA. With a 1/f noise of 2.4 nV/√Hz at 10 Hz and a spurious-free dynamic range of −80 dBc at 2 MHz, the ADA4897-2-KGD is an ideal solution in a variety of applications, including ultrasound, low noise preamplifiers, and drivers of high performance analog-to-digital converters (ADCs). The Analog Devices, Inc., proprietary next generation silicon germanium (SiGe) bipolar process and innovative architecture enable such high performance amplifiers.
■The ADA4897-2-KGD has a 230 MHz bandwidth, a 120 V/μs slew rate, and settles to 0.1% in 45 ns. With a wide supply voltage range of 3 V to 10 V, the ADA4897-2-KGD is ideal for systems that require high dynamic range, precision, low power, and high speed.
■The ADA4897-2-KGD is rated to work over the industrial temperature range of −40°C to +125°C.
