ACDA04-41SRWA-F01 is a kind of LED character and numeric display modules, which is made up of four 7-segment LED display and utilizes a CMOS IC to control the drive of four digital and one decimal point of 7-segment.

Application Field

ACDA04-41SRWA-F01 has many application fields such as digital mechanical measuring equipment, digital recording instruments and digital power meter, etc. It is suitable to display digital information that needs to show in a readout form with four digits. It has various advantages including good clarity, low current draw, great reliability and well brightness.

Working Principle

The driving IC of ACDA04-41SRWA-F01 offers high degree of integration to decrease the number of external components and achieve lower voltage working condition. It has the shifting register and latch adjacent loading. It offers the multiplex rate up to 5kHz, suitable for the application with multiplex rate 7kHz and multiplex code considering the power dissipation.

The integrated input port required for the current mode couldn’t be connected directly from the external circuit due to the electric specs, by controlling anode side voltage to reach the demand. The brightness can be adjusted by selecting the value of current. The brightness is mainly dependent on the current flow of LED.

The LED figure display can meet both AC and DC electric demands. It has broad viewing angle due to the use of chip LED. The circuit design can guarantee the reliability of aging performance. The control board can be designed in an appropriate size to satisfy the need of multiple digit display.
