M62342FP

Preliminary Datasheet M62342P/FP, M62343P/FP 8-Bit D/A Converter (Buffered) R03DS0040EJ0500 Rev.5.00 Jun 03, 2011 Description The M62342 and M62343 are CMOS-structure semiconductor integrated circuits incorporating two or three 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. 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 CTV, and display monitors, conversion from digital data to analog data in consumer and industrial products Block Diagram VCC 4 LD CLK DI 8 76 10-bit shift register 8 Channel decoder GND 5 8-bit latch 8-bit upper segment R-2R +− 8-bit latch 8-bit upper segment R-2R +− 8-bit latch 8-bit upper segment R-2R ← M62343 only +− 123 AO1 AO2 AO3 (NC in M62342) R03DS0040EJ0500 Rev.5.00 Jun 03, 2011 Page 1 of 8 M62342P/FP, M62343P/FP Pin Arrangement M62342P/FP M62343P/FP AO1 AO2 AO3* VCC 1 2 3 4 8 LD 7 CLK 6 DI 5 GND (Top view) Not...
