GENERAL DESCRIPTION

The AD8031 (single) and AD8032 (dual) single-supply, voltagefeedback amplifiers feature high speed performance with80 MHz of small signal bandwidth, 30 V/μs slew rate, and 125 nssettling time.

This performance is possible while consuming lessthan 4.0 mW of power from a single 5 V supply. These featuresincrease the operation time of high speed, battery-poweredsystems without compromising dynamic performance.

The products have true single-supply capability with rail-to-railinput and output characteristics and are specified for +2.7 V, +5 V,and ±5 V supplies. The input voltage range can extend to 500 mVbeyond each rail.

The output voltage swings to within 20 mV ofeach rail providing the maximum output dynamic range.The AD8031/AD8032 also offer excellent signal quality for only800 μA of supply current per amplifier; 

THD is −62 dBc with a2 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 fastsettling time make them ideal as buffers to single-supply ADCs 

Operating on supplies from +2.7 V to +12 V and dual suppliesup to ±6 V, the AD8031/AD8032 are ideal for a wide range ofapplications, from battery-operated systems with large bandwidthrequirements to high speed systems where component densityrequires lower power dissipation.

The AD8031/AD8032 areavailable in 8-lead PDIP and 8-lead SOIC_N packages andoperate over the industrial temperature range of −40°C to+85°C. The AD8031A is also available in the space-saving5-lead SOT-23 package, and the AD8032A is available in an8-lead MSOP package.
