低功耗，高速轨到轨输入/输出放大器 Low Power, High Speed Rail-to-Rail Input/Output Amplifier
Product Details
The AD8040 is a quad, rail-to-rail input and output high speed amplifier with a quiescent current of only 1.3 mA per amplifier. Despite its low power consumption, the amplifier provides excellent performance with 125MHz small signal bandwidth and 60 V/µs slew rate. "s proprietary XFCB process enables high speed and high performance on low power.
This amplifier exhibits true single-supply operation with rail-to-rail input and output performance for supply voltages ranging from 2.7V to 12V. The input voltage range extends 200 mV beyond each rail without phase reversal. The dynamic range of the output extends to within 40 mV of each rail.
The AD8040 provides excellent signal quality with minimal power dissipation. At G=+1, SFDR is -72dBc at 1MHz and settling time to 0.1% is only 80 ns. Low distortion and fast settling performance makes this amplifier a suitable driver for single-supply A/D converters.
The versatility of the AD8040 allows the user to operate the amplifier on a wide range of supplies while consuming less than 6.5 mW of power. This feature extends the operation time in applications ranging from battery-powered systems with large bandwidth requirements to high speed systems where component density requires lower power dissipation.
The amplifier is rated over the extended industrial temperature range, -40°C to +125°C.
