| M62342GP 8-Bit, 2-Channel D-A Converter (Buffered) REJ03F0074-0100Z Rev.1.0 Sep.19.2003 Description The M62342GP is a CMOS-structure semiconductor integrated circuit incorporating two 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. This product is currently under development, and specifications and other details may be modified at a future date. Features * Data transfer format 10-bit serial data input type * Output buffer op-amps Operable over entire voltage range from almost ground to VCC (0 to 5 V) * High output current capacity 1 mA or higher Application Signal gain setting and automatic adjustment in DSC, CTV, and display monitors, conversion from digital data to analog data in consumer and industrial products Pin Connection Diagram (Top View) AO1 AO2 N.C.

With this IC, D-A converter upper reference voltage setting is performed by means of the power supply voltage. If ripples or spikes are imposed on this pin, conversion accuracy may fall. When using this IC, a capacitor must be inserted between the power supply pin and GND in order to ensure stable D-A conversion. 2. The output buffer amps of this IC are highly tolerant of capacitive loads. Therefore, connecting capacitors (0.1 F max.) between the output pins and ground in order to eliminate jitter or noise due to output line wiring presents no problems whatever in terms of operation.
