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.
