Analog Devices Announces Industry’s Fastest, 1nV/root Hz, Low Power, Rail-to-Rail Amplifiers
Analog Devices unveiled a series of high-speed amplifiers that establish a new performance standard with the best combination of high-speed, low noise and low power. Designed for portable, multi-channel and low power instrumentation and healthcare equipment, the ADA4896-2 (dual), ADA4897-1(single) and ADA4897-2 (dual) high-speed amplifiers provide the highest large-signal bandwidth and slew rate with the lowest noise available today in a rail-to-rail amplifier under 10 mW.
Each amplifier features low noise of 1 nV/√Hz and 120-V/vs slew rate while consuming only 3 mA of supply current. Further, the 1/f noise @10Hz is a low 2.4 nV/rootHz.
The new rail-to-rail amplifiers operate across the extended industrial temperature range of -40˚C to +125˚C and offer a 3-V to 10-V supply range. The ADA4895-2 and ADA4897-1/ -2 include an output disable feature.
