16 SEGMENT LED DRIVER
The UAA2022 is a 16-bit serial data input to a l6-Segment L E D
driver. Brightness control of common anode LED’s from an external
control voltage is possible. The UAA2022 is particularly suitable for
Hi-Fi applications and is implemented in I’L linear technology.
l LED brightness control voltage
l Current Source Segment driver Outputs
l No external resistors for Segment currents
8 Non-multiplexed, therefore no RFI ,
