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.
