The UAA2022 from Motorola Semiconductor is a versatile 16-segment LED driver designed for applications requiring precise control of common anode LEDs. This integrated circuit features a 16-bit serial data input, allowing for easy interface with microprocessors.
Key features include external brightness control via a control voltage, enabling dynamic adjustment of LED intensity. The device incorporates current source segment driver outputs, eliminating the need for external resistors to set segment currents for full luminosity. Its non-multiplexed design ensures no RFI generation, making it suitable for sensitive applications like Hi-Fi systems.
The UAA2022 is implemented in I²L linear technology and comes in a plastic package, case 724. It is cascadable, allowing for expansion of the driver capabilities. The circuit receives 16-bit serial data through digital inputs for Chip Select, Clock, and Data at TTL levels.
