Designed for portable, multi-channel and low power instrumentation and healthcare equipment, Analog Devices released a series of high-speed amplifiers, which includes the ADA4896-2 (dual), ADA4897-1 (single) and ADA4897-2 (dual) devices. According to ADI, they 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/vHz and 120-V/µs slew rate while consuming only 3 mA of supply current. Further, the 1/f noise @10Hz is a low 2.4 nV/vHz. The 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.
Also announced as part of this high-speed amplifier series was the ADA4895-2 dual de-compensated high-speed amplifier. It delivers 1.5-GHz gain-bandwidth product at gains of +10 and greater.
