LED Drivers--DM134/DM135
16-Bit Constant Current LED Drivers with 3.3v ~ 5v Supply Voltage
General Description
The DM134B、DM135B are constant current drivers specifically designed for LED display applications. The value of constant current can be varied using an external resistor. The devices include a 16-bit shift register, latches, and constant current drivers on a single Silicon CMOS chip.
Features
3.3V~5V CMOS Compatible Input
Maximum Clock Frequency: 25MHz (Cascade Operation)
Maximum Output Voltage: 17V
Package: DIP24, SOP24, SSOP24, QFN32
Package and Pin Layout: Pin layout and functionality are similar to those of the ST2221C.
(Each characteristic value is different.)
Constant Current Matching: (Ta = 25°C、VDD = 5.0V)
Chip-to-Chip: ± 10.0%
Bit-to-Bit:
DM134B:± 4.0% @ IOUT = 30 ~ 90mA
± 6.0% @ IOUT = 20 ~ 30mA
DM135B:± 4.0% @ IOUT = 20 ~ 60mA
± 6.0% @ IOUT = 5 ~ 20mA
