Preliminary
PT8214
DESCRIPTION
PT8214 is an 8-bit D/A Converter IC with operational amplifier output buffers. It supports up to a
maximum of 36 channels and provides two reference voltages which enable its 36 channels to be used as
12 and 24 independent channels. Digital data are inputted in serially and is controlled by the CLK and
STB Pins making a cascading connection between devices. Available in 48 pins, LQFP package,
PT8214 is capable of large current drive since each channel has an operational amplifier output buffer.
Pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages.
