GENERAL DESCRIPTION
The ADA4807-1 (single), ADA4807-2 (dual), and ADA4807-4 These amplifiers are fully specified at +3 V, +5 V, and ±5 V supplies (quad) are low noise, rail-to-rail input and output, voltage and can operate over the industrial −40°C to +125°C feedback amplifiers. These amplifiers combine low power, low temperature range. noise, high speed, and dc precision to provide an attractive The ADA4807-1 is available in 6-lead SOT-23 and space-saving solution for a wide range of applications from high resolution 6-lead SC70 packages. The ADA4807-2 is available in an 8-lead data acquisition instrumentation to high performance battery- MSOP and a compact, 3 mm × 3 mm, 10-lead LFCSP. The powered and high component density systems where power ADA4807-4 is available in a 14-lead TSSOP package. consumption is of key importance. With only 1.0 mA of supply current per amplifier, the ADA4807-1/
