ADA4807-2 Rail-to-Rail Input/Output Amplifier Evaluation Board
The ADA4807-1/ADA4807-2 are low power, low noise, rail-to-rail voltage feedback amplifiers with exceptionally high performance. They are designed to have the lowest input noise (3.1 nV/√Hz and 0.7 pA/√Hz) among high speed, rail-to-rail amplifiers in the industry while operating on only 1 mA or less of quiescent supply current, making them 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 operate over a wide range of supply voltages from ±1.5 V to ±5 V, as well as from 3 V to 10 V single supplies, and include a disable feature that allows reduction of the typical quiescent supply current to 2.4 μA or less when asserted. For systems with high dynamic range signals, the output voltage swings to within 50 mV of each rail, maximizing the output cdynamic range, and the full, rail-to-rail input stage permits input operation up to and beyond the supply rails. The ADA4807 feature high speed performance of 180 MHz small signal −3 dB bandwidth, a 225 V/μs slew rate, and a settling time of 47 ns to 0.1% (4 V step) with a low input offset voltage of ±20 μV and 0.7 μV/°C drift. For ±5 V supplies, the HD2 is −112 dBc and HD3 is –115 dBc for a 2 V p-p, 100 kHz output signal driving a 1 kΩ load. The low distortion and fast settling time make these amplifiers ideal for driving high speed single-supply precision ADCs with up to 18-bit resolution. The ADA4807 deliver this excellent performance while consuming 1 mA or less of quiescent current. The ADA4807-1 (single) is available in space-saving 6-lead SC70 and 6-lead SOT-23 packages. The ADA4807-2 (dual) is available in 10-lead LFCSP and 8-lead MSOP packages. The ADA4807 operate over the −40°C to 125°C industrial temperature range.
