GENERAL DESCRIPTION
ev. 0 | Page 1 of 13
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.
The I2C address for the AD5801 is TBD.
