GENERAL DESCRIPTION
The AD8031 (single) and AD8032 (dual) single-supply, voltage
feedback amplifiers feature high speed performance with
80 MHz of small signal bandwidth, 30 V/μs 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 μA 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 ADCs.

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 PDIP and 8-lead SOIC_N packages and
operate over the industrial temperature range of −40°C to
+85°C. The AD8031A is also available in the space-saving
5-lead SOT-23 package, and the AD8032A is available in an
8-lead MSOP package.
