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, a.

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) Note: Outline: PRDP0008AA-A (8P4) [P] (not recommend for new design) PRSP0008DE-C [FP] (recommend) PRSP0008DA-A (8P2S-A) [FP] (not recommend for new design) Pin 3 of the M62342 is a NC pin. Preliminary Pin Description Pin No. 6 7 Symbol DI CLK 8 LD 1 AO1 2 AO2 3 AO3 (M62343 only) 4 VCC 5 GND Function Serial data input pin. Inputs serial data with a 10-bit data length. Serial clock input pin. Input signal from DI pin is input to 10-bit shift register at rise of shift clock. Load pin. When “H” level is input to LD pin, value in 10-bit shift register is loaded into decoder and D/A output register. 8-bit resolution D/A converter output pins (After power-on, all channels are reset and DAC data 00h is output.)
