AK8452
2 channel-input 16 bit 10MSPS ADC
Device Outline
■ AFE Block
The AK8452 is a +3.3 V, Two Channel 16 Bit 10MSPS ADC which integrates on-chip Offset Adjust DAC, Gain Adjust PGA, CDS circuit and <4.5~5.7V> 3 channel LED Drivers. ■ LED Drive Block
This product is the 3 channel LED driver who drives the LED of the anode common in the constant current. The current to pass for each channel can be adjusted by the external resistance and the register setting. Also, it has the control pins which turn on or off the current.
