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.
