VC Analog Common Voltage 2.7 3.05 3.35 V 250k Ω Between Common and V+ LCD Drive VSD LCD Segment Drive Voltage 4 5 6 VP-P V+ to V- = 9V VBD LCD Backplane Drive Voltage 4 5 6 VP-P V+ to V- = 9V Power Supply IS Power Supply Current — 55 100 μAVIN = 0V, V+ to V- = 9V (Note 6) TABLE 1-1: TC7126/A ELECTRICAL SPECIFICATIONS (CONTINUED) Electrical Characteristics: VS = +9V, fCLK – 16kHz, and TA = +25°C, unless otherwise noted. Symbol Parameter Min Typ Max Unit Test Conditions Note 1: Input voltages may exceed the supply voltages, provided the input current is limited to ±100 μA. 2: Dissipation rating assumes device is mounted with all leads soldered to printed circuit board. 3: Refer to “Differential Input” discussion. 4: Backplane drive is in phase with segment drive for “OFF” segment, 180° out of phase for “ON” segment. Frequency is 20 times conversion rate. Average DC component is less than 50mV. 5: See “Typical Application”. 6: During Auto-Zero phase, current is 10-20 μA higher. A 48kHz ocillator increases current by 8μA (Typical). Common current is not included. |
