(Note 3) TC7106/A & TC7107/A Parameters Test Conditions Min Typ Max Unit Analog Common Voltage 25k Ω Between Common 2.7 3.05 3.35 V (With Respect to Pos. Supply) and Pos. Supply Temp. Coeff. of 25k Ω Between Common Analog Common and Pos. Supply (With Respect 0 °C ≤ TA ≤ +70°C 7106A/7A 20 50 ppm/ °C to Pos. Supply) ("C", Commercial Temp. Range Devices) 7106/7 80 — ppm/ °C Temp. Coeff. of 25k Ω Between Common Analog Common and Pos. Supply (With Respect – 25 °C ≤ TA ≤ 85°C — — 75 ppm/ °C to Pos. Supply) (“I,” Industrial Temp. Range Devices) TC7106A ONLY Pk – Pk V+ to V– = 9V 4 5 6 V Segment Drive Voltage (Note 5) TC7106A ONLY Pk – Pk V+ to V– = 9V 4 5 6 V Backplane Drive Voltage (Note 5) TC7107A ONLY V+ = 5.0V 5 8.0 — mA Segment Sinking Current (Except Pin 19) Segment Voltage = 3V TC7107A ONLY V+ = 5.0V 10 16 — mA Segment Sinking Current (Pin 19) Segment Voltage = 3V NOTES: 1. Input voltages may exceed the supply voltages provided the input current is limited to ±100µA. 2. Dissipation rating assumes device is mounted with all leads soldered to printed circuit board. 3. Unless otherwise noted, specifications apply to both the TC7106/A and TC7107/A at TA = 25°C, fCLOCK = 48 kHz. Parts 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 50mV. TC7106 TC7106A TC7107 TC7107A 3-1/2 DIGIT A/D CONVERTERS |
