The DM134B from NA is a 16-bit constant current LED driver specifically engineered for LED display applications. This integrated circuit features a 16-bit shift register, latches, and constant current drivers on a single CMOS chip. The constant current value can be adjusted using an external resistor, simplifying design and reducing component count compared to using individual resistors for each LED.
Key electrical specifications include a supply voltage range of 3.3V to 5V and a maximum output voltage of 17V. The device supports a maximum clock frequency of 25MHz for cascade operation. Constant current matching is provided with chip-to-chip tolerance of ±10.0% and bit-to-bit tolerances of ±4.0% to ±6.0% depending on the output current range.
The DM134B is available in multiple package options: DIP24, SOP24, SSOP24, and QFN32, offering flexibility for various PCB designs and manufacturing processes. Its design is suitable for applications requiring precise current control for LED arrays and displays.
