Product Details

The ADA4807-1 is a low power, low noise, rail-to-rail voltage feedback amplifier with exceptionally high performance. It is 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 it 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 operates 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 includes a disable feature that allows reduction of the typical quiescent supply current to 2.4 μA when asserted.

For systems with high dynamic range signals, the output voltage swings to within 50 mV of each rail, maximizing the output dynamic range, and the full, rail-to-rail input stage permits input operation up to and beyond the supply rails.

The ADA4807-1 features high speed performance of 200 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 125 μV (maximum) 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 makes this amplifier ideal for driving high speed single-supply precision ADCs with up to 18-bit resolution. The ADA4807-1 delivers this excellent performance while consuming 1 mA or less of quiescent.


The ADA4807-1 (single) is available in space-saving 6-lead SC70 and 6-lead SOT-23 packages, and each operates over the −40°C to +125°C industrial temperature range.

Applications
  • High speed, battery operated systems
  • High component density systems
  • High resolution analog-to-digital converter (ADC) drivers
