XR1008, XR2008
0.5mA, 75MHz Rail-to-Rail Amplifiers
General Description
The XR1008 (single) and XR2008 (dual) are rail-to-rail output ampli ers that
offer superior dynamic performance with 75MHz small signal bandwidth
and 50V/μs slew rate. The XR1008 and XR2008 ampli ers consume only
505μA of supply current per channel and are designed to operate from a
supply range of 2.5V to 5.5V (±1.25 to ±2.75).
The combination of low power, high output current drive, and rail-to-rail
performance make the XR1008 and XR2008 well suited for battery-powered
metering and test equipment.
The combination of low cost and high performance make these ampli ers
suitable for high volume industrial applications such as ultrasonic heat
meters, water meters and other applications requiring high speed and low
power.
