ANALOG DEVICES AD8390AACPZ-R7 差分放大器, 高输出电流, 3 放大器, 1 mV, 45 MHz, -40 °C, 85 °C
GENERAL DESCRIPTION
The AD8390A is a high output current, low power consumption differential amplifier. It is particularly well suited for the central office CO driver interface in digital subscriber line systems such as ADSL and ADSL2+. In full bias operation, the driver delivers 20.4 dBm output power into low resistance loads while compensating for hybrid and transformer insertion losses and back termination resistors.
The AD8390A is available in a thermally enhanced LFCSP package 16-lead LFCSP. Significant control and flexibility in bias current have been designed into the AD8390A.
Four power modes are selectable via two digital inputs, PD0 and PD1, providing three levels of driver bias and one power-down state. In addition, the IADJ pin is available for fine quiescent current trimming to tailor the performance of the AD8390A.
The low power consumption, high output current, high output voltage swing, and robust thermal packaging enable the AD8390A to be used as the central office line driver in ADSL, ADSL2+, and proprietary xDSL systems, as well as in other high current applications requiring a differential amplifier.
