Input range: VRB to VRT (2 Vp-p between 0.5 to 3 V) Reference voltage input pin (3 V) Reference voltage input pin (1 V) Reference voltage output pin. When connected to VRB, the pin generates 0.33 × AVDD (1 V). No connection pin. Should be connected to AVDD. Functions Analog power supply pins (+3 V) Values within ( ) are typical values. s NOTES ON USE • Be sure to bypass the AVDD, DVDD, VRT and VRB pins to the ground using a high-frequency capacitor. The high-frequency capacitor should be connected as near the pin as possible. • Provide four clocks or more immediately after the power up to prevent current dissipation due to the indeterminate internal logic. 2 MB40C368 s ABSOLUTE MAXIMUM RATINGS (See WARNING) Parameter Power supply voltage Input voltage Output voltage Storage temperature Symbol AVDD, DVDD CLK, VINA VRT, VRB D1 to D8 Tstg Rating Min. –0.3 –0.3 –0.3 –55 Max. 0.7 AVDD+0.3 DVDD+0.3 +125 Unit V V V °C WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current, temperature, etc.) in excess of absolute maximum ratings.
