Analog Devices claims industry’s fastest, low noise, low power, rail-to-rail amplifiers
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/ms slew rate while consuming only 3 mA of supply current. Further, the 1/f noise at 10Hz is a low 2.4 nV/√Hz.
Also announced as part of this high-speed amplifier series was the ADA4895-2 dual de-compensated high-speed amplifier. The device delivers 1.5-GHz gain-bandwidth product at gains of +10 and greater, making it ideal as a high-speed, high-gain pre-amplifier.
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.
The ADA4897-1 (single, disable) packaged in a 8-lead SOIC or 6-lead SOT is in full volume production costs $1.89 each per 1,000.
The ADA4897-2 (dual, disable) packaged in a 10-lead MSOP is sampling now and costs $3.20 each per 1,000.
The ADA4896-2 (dual) packaged in a 10-lead MSOP or a 8-lead LFCSP is in full volume production and costs $3.20 each per 1,000.
The ADA4895-2 (dual, disable) packaged in a 10-lead MSOP is sampling now and costs $3.20 each per 1,000.
