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.
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
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.
