1. Describe

ADA4807-1AKSZ-R2 (single), ADA4807-2 (dual) and ADA4807-4 (quad) is a low noise, rail-to-rail input and output, voltage feedback amplifier. These amplifiers combine low power consumption, low noise, high speed and DC accuracy to provide attractive Solutions for a variety of applications from high resolution Data acquisitioninstruments for high performance battery powered and high component density systems where power Consumption is the top priority. With only 1.0 mA supply current per amplifier, the ADA4807-1/The ADA4807-2/ADA4807-4 have the lowest input voltage noise between high-speed, rail-to-rail input/output amplifiers industry and provide wide bandwidth, high slew rate, fast settling time and excellent distortion performance. Furthermore, these The amplifier provides very low input offset voltage and drift performance, making them ideal for driving multiplexing and high throughput Precision 16-bit/18-bit Successive Approximation Register (SAR) and a 24-bit △-Σ ADC. These amplifiers are fully specified for +3 V, +5 V and ±5 V supplies and can operate in the industrial -40°C to +125°C range temperature range.
