(1) 13 dots x 2ch Log scale (2) 13 dots x 2ch Linear scale (3) 26 dots x 1ch Linear scale • 2 display (DSP) pins for direct display. • Microcomputer-controlled data input using 3 pins for serial data input and control. • The full scale of the AD converter is 31/48Vref. The Vref is variable (with Vref pin). • Available for increased use in general-purpose applications because no decoder is required to display the segment data. • Control bits used to cause the segment output and AD output to be lighted/unlighted. • RES pin used to cause the initial mode to be entered. 3.0 1.0 SANYO : QIP64B Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft’s control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO representative nearest you before using any SANYO products described or contained herein in such applications. SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other parameters) listed in products specifications of any and all SANYO products described or contained herein.
