GENERAL DESCRIPTION
The AD8029 (single), AD8030 (dual), and AD8040 (quad) are
rail-to-rail input and output high speed amplifiers with a
quiescent current of only 1.3 mA per amplifier. Despite their
low power consumption, the amplifiers provide excellent
performance with 125 MHz small signal bandwidth and
60 V/µs slew rate. ADI’s proprietary XFCB process enables high
speed and high performance on low power.
This family of amplifiers exhibits true single-supply operation
with rail-to-rail input and output performance for supply
voltages ranging from 2.7 V to 12 V. The input voltage range
extends 200 mV beyond each rail without phase reversal. The
dynamic range of the output extends to within 40 mV of each
rail.
The AD8029/AD8030/AD8040 provide excellent signal quality
with minimal power dissipation. At G = +1, SFDR is –72 dBc at
1 MHz and settling time to 0.1% is only 80 ns. Low distortion
and fast settling performance make these amplifiers suitable
drivers for single-supply A/D converters.
The versatility of the AD8029/AD8030/AD8040 allows the user
to operate the amplifiers on a wide range of supplies while
consuming less than 6.5 mW of power. These features extend
the operation time in applications ranging from battery-
powered systems with large bandwidth requirements to high
speed systems where component density requires lower power
dissipation.
The AD8029/AD8030 are the only low power, rail-to-rail input
and output high speed amplifiers available in SOT23 and SC70
micro packages. The amplifiers are rated over the extended
industrial temperature range, –40°C to +125°C.
