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/ 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 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

NOTES
1Stresses above those listed under Absolute Maximum Ratings may cause permanent 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.
2Specification is for the device in free air: 8-Lead Plastic DIP Package: θJA = 90°C/W. 8-Lead SOIC Package: θJA = 155°C/W. 8-Lead µSOIC Package: θJA = 200°C/W. 5-Lead SOT-23-5 Package: θJA = 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 plastic 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 performance 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 protected, this may not be sufficient to guarantee that the maximum 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.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD8031/AD8032 feature proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
