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. Analog
Devices, Inc., proprietary XFCB process enables high speed and
high performance on low power.
systems where component density requires lower power
dissipation. The AD8040W is an automotive grade version,
qualified for automotive applications.
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.
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 analog-to-digital converters.

The versatility of the AD8029/AD8030/AD8040 allows the user
to operate the amplifiers on a wide range of supplies while con-
suming 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
