These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operation sections of the specifications is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. TC7116/A AND TC7117/A ELECTRICAL SPECIFICATIONS Electrical Characteristics: Unless otherwise noted, specifications apply to both the TC7116/A and TC7117/A at TA =25°C, fCLOCK = 48kHz. Parts are tested in the circuit of the Typical Operating Circuit. Symbol Parameter Min Typ Max Unit Test Conditions ZIR Zero Input Reading — ±0 — Digital Reading VIN =0V Full Scale = 200mV Ratiometric Reading 999 999/1000 1000 Digital Reading VIN =VREF VREF =100mV R/O Rollover Error (Difference in Reading for Equal Positive and Negative Readings Near Full Scale) -1 ±0.2 +1 Counts VIN- =+VIN+ ≅ 200mV or ≈ 2V Linearity (Maximum Deviation from Best Straight Line Fit) -1 ±0.2 +1 Counts Full Scale = 200mV or 2V CMRR Common Mode Rejection Ratio (Note 3) —50 — µV/V VCM =±1V, VIN =0V Full Scale = 200mV eN Noise (Peak to Peak 95% of Time) — 15 — µVV IN =0V Full Scale = 200mV IL Leakage Current at Input — 1 10 pA VIN =0V Zero Reading Drift — 0.2 1 µV/°C VIN =0V “C” Device = 0°C to +70°C —1.0 2 µV/°C “I” Device= -25°C to+85°C 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: 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. |
