| MITSUBISHI M62366GP 3V TYPE 8-BIT 12CH D-A CONVERTER WITH BUFFER AMPLIFIERS DESCRIPTION The M62366GP is a CMOS semiconductor IC,containing 12 channels of 8-bit D-A converters,with a high-performance buffer operational amplifier provided in the output of each channel. It is operable with a low supply voltage between 2.7~3.6V,and is easy to use due to serial data input,and 3-pin(DI,CLK,LD)connection with microcomputer. The IC also contains Do pin terminal,enabling cascade connection.The built-in buffer operational amplifiers are of full-swing design with a wide operating supply voltage range for input/output voltage.In addition,this IC provides improved stability against a capacitive load,and therefore is suitable for application to electronic volume(VCA)control,substitute for adjustment semi-fixed resistor,etc. PIN CONFIGURATION (TOP VIEW) VSS 1 (VrefL) Ao3 2 Ao4 Ao5 Ao6 Ao7 Ao8 Ao9 Ao10 3 4 5 6 7 8 9 20 19 18 17 16 15 14 13 12 11 GND Ao2 Ao1 DI CLK LD Do Ao12 Ao11 Vcc FEATURES *Operable with a low voltage between 2.7~3.6V *12-bit serial data input(connected via 3 pins:DI,CLK,LD) *12 channels of R-2R and segment type high-performance 8-bit D-A converters *12 buffer operational amplifiers with full swing of output voltage between Vcc and GND. *High oscillation stability against the capacitive load of buffer operational amplifiers.
