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.
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.
Table 1. Other Rail-to-Rail Amplifiers
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.
