GENERAL DESCRIPTION
The ADA4895-1 (single) and ADA4895-2 (dual) are high speed voltage feedback amplifiers that are gain ≥ 10 stable 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 at 10 Hz and a spuriousfree dynamic range (SFDR) of −72 dBc at 2 MHz, the ADA4895-...
