GENERAL DESCRIPTION

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 battery-

powered 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.

The ADA4807-1 is available in 6-lead SOT-23 and space-saving

6-lead SC70 packages. The ADA4807-2 is available in an 8-lead

MSOP and a compact, 3 mm × 3 mm, 10-lead LFCSP. The

ADA4807-4 is available in a 14-lead TSSOP package.
