Analog Devices High Speed, 1nV/√Hz, Low Power, Rail-to-Rail Output Amplifiers

Analog Devices High Speed, 1nV/√Hz,
Low Power, Rail-to-Rail Output Amplifiers

Analog Devices High Speed, 1nV/√Hz, Low Power, Rail-to-Rail Output Amplifiers are unity-gain stable, low noise, rail-to-rail output, high speed voltage feedback amplifiers that have a quiescent current of 3mA. With a 1/f noise of 2.4nV/√Hz at 10Hz and a spurious-free dynamic range of −80dBc at 2MHz, these are ideal solutions 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 such high performance amplifiers.
