Description
The M62384 is a CMOS-structure semiconductor integrated circuit incorporating four 8-bit D-A converter channels
with output buffer op-amps.
Serial data transfer type input can easily be used through a combination of three lines: DI, CLK, and LD. Outputs
incorporate buffer op-amps that have a drive capacity of 1 mA or above for both sink and source, and can operate over
the entire voltage range from almost ground to VCC (0 to 5 V), making peripheral elements unnecessary and enabling
configuration of a system with few component parts.
Support of power supply voltages of 3 V to 5 V enables the M62384 to be used in a wide range of applications.
Features
• 12-bit serial data input (3-line type: SDI, SCK, SLD)
• Serial data transfer clock frequency: 10 MHz (max.)
• Output buffer op-amps
Operable over entire voltage range from almost ground to VCC
• Power-on reset and external reset functions
• Chip select function
Up to 4 chips connectable on the same bus
• Supported power supply voltage: 3 V to 5 V (2.7 V to 5.5 V)
Application
Signal gain setting and automatic adjustment in CTV and display monitors, conversion from digital data to analog data
in consumer and industrial products
