Parameter Test Conditions Min Typ Max Unit Temperature Coefficient of Analog Common "I" Device: –25 °C to +85°C — — 75 ppm/ °C (With Respect to Positive Supply) 25 k Ω Between Common and Positive Supply (TC7116A/TC7117A) TC7116/TC7116A ONLY Peak-to-Peak V+ to V– = 9V 4 5 6 V Segment Drive Voltage (Note 5) TC7116/TC7116A ONLY Peak-to-Peak V+ to V– = 9V 4 5 6 V Backplane Drive Voltage (Note 5) TC7117/TC7117A ONLY Segment V+ = 5V 5 8 — mA Sinking Current (Except Pin 19) Segment Voltage = 3V TC7117/TC7117A ONLY Segment V+ = 5V 10 16 — mA Sinking Current (Pin 19 Only) Segment Voltage = 3V NOTES: 1. Input voltages may exceed supply voltages, provided input current is limited to ±100 µA. 2. Dissipation rating assumes device is mounted with all leads soldered to printed circuit board. 3. Unless otherwise noted, specifications apply at TA = +25°C, fCLOCK = 48 kHz. TC7116/TC7116A and TC7117/TC7117A are tested in the circuit of Figure 1. 4. Refer to "Differential Input" discussion. 5. 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 50 mV. 6. The TC7116/TC7116A logic inputs have an internal pull-down resistor connected from HLDR, pin 1 to TEST, pin 37. The TC7117/TC7117A logic inputs have an internal pull-down resistor connected from HLDR, pin 1 to GND, pin 21. |
