1 nV/√Hz, Low Power, Rail-to-Rail Output Amplifier Known Good Die ADA4897-2-KGD FEATURES GENERAL DESCRIPTION Low wideband noise
The ADA4897-2-KGD1 is a unity-gain stable, low noise, rail-to-
1 nV/√Hz
rail output, high speed voltage feedback amplifier that has a
2.8 pA/√Hz
quiescent current of 3 mA. With a 1/f noise of 2.4 nV/√Hz at
Low 1/f noise: 2.4 nV/√Hz at 10 Hz
10 Hz and a spurious-free dynamic range of −80 dBc at 2 MHz,
Low distortion: −115 dBc at 100 kHz, VOUT = 2 V p-p
the ADA4897-2-KGD is an ideal solution in a variety of
Low input offset voltage: 500 μV maximum
applications, including ultrasound, low noise preamplifiers, and
High speed
drivers of high performance analog-to-digital converters (ADCs).
−3 dB bandwidth: 230 MHz (G = +1)
