Analog Devices Inc. AD8029/AD8030/AD8040轨到轨I/O放大器
Analog Devices AD8029/AD8030/AD8040高速轨到轨输入/输出放大器采用Analog Devices专有的XFCB工艺开发。得益于XFCB工艺，AD8029/AD8030/AD8040放大器可使用低压电源提供出色的高速性能。AD8029/AD8030/AD8040放大器包括单通道/双通道/四通道轨到轨输入与输出放大器，每放大器的静态电流仅为1.3mA。虽然AD8029/AD8030/AD8040器件的功耗很低，但却能提供出色的性能，小信号带宽为125MHz，压摆率为60V/µs。另外，AD8029/AD8030/AD8040放大器采用单电源供电，具有轨到轨输入和输出，电源电压范围为2.7V至12V。输入电压范围可以超过各供电轨200mV而不会反相。输出动态范围可以扩展至各供电轨40mV以内。这些器件以极低的功耗提供出色的信号质量。在G = +1时，无杂散动态范围 (SFDR) 为-72dBc (1MHz)，0.1%建立时间仅为80ns。低失真和快速建立特性使AD8029/AD8030/AD8040放大器非常适合用作单电源模数转换器的驱动器。
In addition, the AD8029/AD8030/AD8040 Amplifiers exhibit true single-supply operation with rail-to-rail input and output performance for 2.7V to 12V supply voltages. The input voltage range extends 200mV beyond each rail without phase reversal. The output dynamic range extends to within 40mV of each rail. Excellent signal quality is achieved with minimal power dissipation. At G = +1, SFDR is –72dBc at 1MHz and settling time to 0.1% is only 80ns. Low distortion and fast settling performance make the AD8029/AD8030/AD8040 Amplifiers ideal for drivers for single-supply analog-to-digital converters.
