AD8031

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 4.0 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 mA 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 industrial 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.
