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.
