Analog Devices Inc. ADA4807-1/-2/-4 Operational Amplifiers
Analog Devices ADA4807-1 Single-Channel, ADA4807-2 Dual-Channel, ADA4807-4 Quad-Channel Operational Amplifiers are low power, low noise, rail-to-rail voltage feedback amplifiers with exceptionally high performance. The ADA4807-1/ADA4807-2/ADA4807-4 op-amps are designed to have a low input noise while operating on only 1mA or less of quiescent supply current. The low quiescent current operation makes the ADA4807-1/ADA4807-2/ADA4807-4 ideal for a wide range of applications from battery-powered, portable instrumentation to high-speed systems where component density requires lower power dissipation.
The ADA4807-1/ADA4807-2/ADA4807-4 op-amps operate over a wide range of supply voltages from ±1.5V to ±5V, as well as from 3V to 10V single supplies. The op-amps include a disable feature to reduce the typical quiescent supply current to 2.4μA or less when asserted.
Operating over the -40°C to +125°C industrial temperature range, ADA4807-1/ADA4807-2/ADA4807-4 op-amps deliver a high-speed performance of 180MHz with small signal −3 dB bandwidth, a 225V/μs slew rate, and a settling time of 47ns to 0.1% (4V step) with a low input offset voltage of ±20μV and 0.7 μV/°C drift. For ±5V supplies, the HD2 is −112dBc and HD3 is -115dBc for a 2Vp-p, 100kHz output signal driving a 1 kΩ load. The low distortion and fast settling time make the ADA4807-1/ADA4807-2/ADA4807/4 op amps ideal for driving high-speed single-supply precision ADCs with up to 18-bit resolution.

Integration and Collaboration at the Heart of a High Performance Image Sensor Reference Design
In collaboration with Hamamatsu Photonics, Inc., Analog Devices has built a high-performance analog front-end (AFE) board to interface with the Hamamatsu G920x linear array NIR/SWIR InGaAs Image Sensor Family. Image sensors in the 920x family include an integrated Thermoelectric Cooler (TEC) to cool the optical detectors for extremely low noise operation, making them an excellent choice for high-performance NIR/SWIR spectroscopy applications such as gas and mineral identification.
Can You Really Get ppm Accuracies from Op Amps?
There is a march toward 1 ppm accurate systems, especially now that 1 ppm linear ADCs are becoming common. This article presents op-amp accuracy limitations and how to choose the few op-amps that have a chance of 1 ppm accuracy.
