NOTES: 3. When channel IN– is more positive than channel IN+, the digital output code is 0000 0000. Connected to each analog input are two on-chip diodes that conduct forward current for analog input voltages one diode drop above VCC. Care must be taken during testing at low VCC levels (4.5 V) because high-level analog input voltage (5 V) can, especially at high temperatures, cause the input diode to conduct and cause errors for analog inputs that are near full scale. As long as the analog voltage does not exceed the supply voltage by more than 50 mV, the output code is correct. To achieve an absolute 0- to 5-V input range requires a minimum VCC of 4.95 V for all variations of temperature and load. 4. Standby input currents go in or out of the on or off channels when the A/D converter is not performing conversion and the clock is in a high or low steady-state conditions. total device PARAMETER MIN TYP‡ MAX UNIT ICC Supply current TLC0831 0.6 1.25 mA ICC Supply current TLC0832 2.5 4.7 mA ‡ All typical values are at VCC = 5 V, TA = 25°C. |
