8-Bit D/A Converter IC

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.

FEATURES

• CMOS technology

• Very low power consumption: Type 1.1mW/channel

• Max. 2.5MHz serial data input

• Separate supply voltages for digital and analog blocks

• R-2R resistor ladder conversion method

• On-chip operational amplifier output buffers: Max. +1.0/-1.0mA analog output sink/source current

capability

• Analog data output range: 0 to Vcc (V)

• Two analog output reference voltage

• Analog data can be outputted in different reference voltages

• Available in 48 pins, LQFP package

APPLICATIONS

• Digital equipment

• V8

• CD ROM/VCD

• MPEG

• Sound card

• Replacement for potentiometers
