1 Datasheet M62342P/FP, M62343P/FP 8-Bit D/ Converter (Buffered) R03DS0040J0500 Rev.5.00 Description The M62342 and M62343 are CMOS-structure semiconductor integrated circuits incorporating two or three 8-bit D/ 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 m or above for both sink and source, and can operate over the entire voltage range from almost ground to V CC (0 to 5 V), making peripheral elements unnecessary and enabling configuration of a system with few component parts. Features Data transfer format 0-bit serial data input type Output buffer op-amps Operable over entire voltage range from almost ground to V CC (0 to 5 V) High output current capacity ± m or higher pplication Signal gain setting and automatic adjustment in CTV, and display monitors, conversion from digital data to analog data in consumer and industrial products Block Diagram V CC LD CLK DI GND bit shift register 8 Channel decoder 8-bit latch 8-bit latch 8-bit latch 8-bit upper segment R-2R 8-bit upper segment R-2R 8-bit upper segment R-2R M62343 only 2 3 O O2 O3 (NC in M62342) R03DS0040J0500 Rev.5.00 Page of 8

6 Usage Notes. With this IC, D/ 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/ conversion. 2. The output buffer amps of this IC are highly tolerant of capacitive loads. Therefore, connecting capacitors (0. μf 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.
