GENERAL DESCRIPTION
The AD8031 (single) and AD8032 (dual) single supply voltage
feedback amplifiers feature high-speed performance with 80MHz
of small signal bandwidth, 30 V/
μ
s slew rate and 125 ns settling
time. This performance is possible while consuming less than
4.0 mW of power from a single +5 V supply. These features
increase the operation time of high speed battery-powered
systems without compromising dynamic performance.
The products have true single supply capability with rail-to-rail
input and output characteristics and are specified for +2.7 V,
+5 V and
±
5 V supplies. The input voltage range can extend to
500 mV beyond each rail. The output voltage swings to within
20 mV of each rail providing the maximum output dynamic range.
The AD8031/AD8032 also offer excellent signal quality for only
800
μ
A of supply current per amplifier; THD is –62 dBc with a
2 V p-p, 1 MHz output signal and –86 dBc for a 100 kHz, 4.6 V p-p
signal on +5 V supply. The low distortion and fast settling
time
make them ideal as buffers to single supply, A-to-D converters.
Operating on supplies from +2.7 V to +12 V and dual supplies up to
±
6 V, the AD8031/AD8032 are ideal for a wide range of applications,
from battery-operated systems with large bandwidth requirements
to high-speed systems where component density requires lower
power dissipation. The AD8031/AD8032 are available in 8-lead
plastic DIP and SOIC packages and will operate over the indus-
trial temperature range of –40
°
C to +85
°
C. The AD8031A is also
available in the space-saving 5-lead SOT-23-5 package and the
AD8032A is available in AN 8-lead
μ
SOIC package.
