16-bit Constant Current LED Driver

Agamem Microelectronics Inc.

PRELIMINARY

DESCRIPTION

The AA1726 is a low voltage; low current and constant-current drivers designed for LEDs and

LED displays. The output current can be set using an external resistor. As a result, all outputs

will have virtually the same current levels. This driver incorporates a 16-bit constant current

output, a 16-bit shift register, a 16-bit latch and a gate circuit. The full-scale constant output

current of each channel will range from 5mA up to 90mA.

FEATURES

• 16 constant current output channels

• Adjustable output current through external resistor

• Serial data IN / parallel data OUT

• Maximum output terminal voltage: 20V

• Output current: 5-90 mA

• Max clock frequency 25 MHz

• Built-in power on reset and thermal protection circuit

• Interlaced 30ns delay of output to lower bouncing noise

• I/O logic: Schmitt trigger input

• Constant-current accuracy (all outputs on)

between bits

+/- 3%

between ICs

+/- 6%

Condition

Iout=10~60mA

• Package: SOP24, SSOP24

APPLICATIONS

• LED Displays

• LED Signboards

• Display Back-lighting
