AK5483
10Bit 20MHz 3CH A/D Converter
Outline
AK5483 is a Cmos, 20MSPS(MAX)ɺ 10bit,Analog to Digital(A/D) Converter.
Three Channels of high Performance ADCs are integrated into a tiny package.
Employing Full-Pipeline A/D Conversion Architecture, AK5483 Converts Single End 1Vpp
Analog Input into 10bit Straight Binary Format Digital Data.
The analog Input Range is determined by external reference input pins[VTP,VBT]. The
range is common for the three channels.
