AD5801中文资料Piezo-Electric Actuator Controller数据手册ADI规格书

描述 Description

GENERAL DESCRIPTION
The AD5801 is a high efficiency ultrasonic motor controller with two Class D-type output drivers. These Class D-type drivers can be used independently or configured as an H-bridge driver, and have full pattern programmability. There are also six integrated drivers which can be operated independently and have programmable output patterns. The AD5801 also has integrated drivers which are programmable from 130mA to 200mA, and may be used for a combination of Shutter and NDF/IRIS control.
The operation modes of the drivers are invoked by the AD5801 using an I2C compatible interface.FEATURES
