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/ms slew rate and 125 ns settling
time. This performance is possible while consuming less than
4.0mW 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 mA of supply current per amplifier; THD is –62 dBc with a
2 V p-p, 1 MHz output signal and –86dBc for a 100kHz, 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 to6 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 mSOIC package.

NOTESStresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.Specification is for the device in free air:
8-Lead Plastic DIP Package: qJA = 90°C/W.
8-Lead SOIC Package: qJA = 155°C/W.
8-Lead mSOIC Package: qJA = 200°C/W.
5-Lead SOT-23-5 Package: qJA = 240°C/W.
MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the
AD8031/AD8032 are limited by the associated rise in junction
temperature. The maximum safe junction temperature for plas-
tic encapsulated devices is determined by the glass transition
temperature of the plastic, approximately +150°C. Exceeding
this limit temporarily may cause a shift in parametric perfor-
mance due to a change in the stresses exerted on the die by
the package. Exceeding a junction temperature of +175°C for
an extended period can result in device failure.
While the AD8031/AD8032 are internally short circuit pro-
tected, this may not be sufficient to guarantee that the maxi-
mum junction temperature (+150°C) is not exceeded under
all conditions. To ensure proper operation, it is necessary to
observe the maximum power derating curves shown in Figure 2.
