ADI ADA4807-2ARMZ

The ADA4807-1 (single), ADA4807-2 (dual), and ADA4807-4 (quad) are low noise, rail-to-rail input and output, voltage feedback amplifiers. These amplifiers combine low power, low noise, high speed, and dc precision to provide an attractive solution for a wide range of applications from high resolution data acquisition instrumentation to high performance batterypowered and high component density systems where power consumption is of key importance. With only 1.0 mA of supply current per amplifier, the ADA4807-1/ ADA4807-2/ADA4807-4 feature the lowest input voltage noise among high speed, rail-to-rail input/output amplifiers in the industry and offer a wide bandwidth, high slew rate, fast settling time, and excellent distortion performance. Additionally, these amplifiers offer very low input offset voltage and drift performance, making them ideal for driving multiplexed and high throughput precision 16-/18-bit successive approximation registers (SARs) and 24-bit - ADCs. These amplifiers are fully specified at +3 V,+5 V, and ±5 V supplies and can operate over the industrial -40°C to +125°C temperature range.
