Package
SSOP24
SD6505 has built-in 24 bits ADC, LED driver, and two-wire communication circuits.
The LED driver circuit can drive up to 56 common cathode LEDs with a maximum drive current of 14 mA, which ensures sufficient brightness from white LEDs.
A host computer can read and edit all the registers in the IC through the two-wire communication circuit.
The IC supports timing measurement comparison mode. After entering this mode, host is turned on after successful data comparison. The host can also turn on the IC independently.
The IC has built-in sine wave generator, temperature sensor, 8 bits DAC, etc., to meet the requirements of various applications.
