UNISONIC TECHNOLOGIES CO., LTD M62364 CMOS IC 8-BIT 8-CH MULTIPLYING D-A CONVERTER WITH BUFFER AMPLIFIERS SOP-24 DESCRIPTION The UTC M62364 is a CMOS 8-bit, 8-ch D/A converter having a multiplying function and output buffer amplifiers. It has a serial data input and can easily communicate with a microcontroller by the simple three-wiring method (DIN, CLK, LD). The output buffer amplifiers operating in AB-class has both sinking and driving capabilities of 1.0mA or more and can operate in a whole supply range from VDD to GND. The IC is suitable for a use in automatic adjustment applications in conjunction with a MCU by utilizing the terminal Do for a cascading connection. SSOP-24 (209mil) FEATURES *Three-wiring serial data transmission *Doubled precision 8-ch D/A converter employing an R-2R with higher-order segment method *8 buffer amplifiers operating in a whole supply voltage range from VDD to GND *4-quadrant multiplication ORDERING INFORMATION Ordering Number M62364G-R24-R M62364G-S24-R Package SSOP-24 SOP-24 Packing Tape Reel Tape Reel MARKING SOP-24 www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd SSOP-24 1 of 8 QW-R502-008.D M62364 CMOS IC PIN CONFIGURATION (TOP VIEW) VIN1 VOUT1 1 2 3 4 VOUT2 VIN2 VDD LD CLK DIN VIN3 VOUT3 5 6 7 8 9 10 11 VOUT4 VIN4 12 24 23 22 21 20 VIN8 VOUT8 VOUT7 VIN7 GND 19 18 17 16 RESET VDA(REF) DOUT VIN6 15 VOUT6 14 VOUT5 VIN5 13 EXPLANATION OF TERMINALS PIN NO 8 17 SYMBOL DIN DOUT 7 CLK 6 LD 19 RESET 2 3 10 11 14 15 22 23 5 20 1 4 9 12 13 16 21 24 18 VOUT1 VOUT2 VOUT3 VOUT4 VOUT5 VOUT6 VOUT7 VOUT8 VDD GND VIN1 VIN2 VIN3 VIN4 VIN5 VIN6 VIN7 VIN8 VDA(REF) FUNCTION Serial data input Serial data output Shift clock input.
