I have a question regarding the voltage specification of the TSH82 OpAmp: Datasheet.
In the data-sheet, maximum ratings I find (Table 1):
- Vcc Supply Voltage 14V
- Vid Differential Input Voltage ±2V
- Vi Input Voltage ±6V
The common mode input voltage range on the other hand is defined as (Table 2): Vcc- to (Vcc+ -1.1). Note that the data-sheet of this part does not use the usual Vcc and Vdd nomenclature but uses Vcc- and Vcc+ instead.
If the common mode input voltage goes basically from negative supply to 1V below positive supply, what does the "Vi Input Voltage ±6V" from table 1 refer to? It seem to contradict with the common mode input voltage range because it's range is much lower when the device is powered from lets say 9V.
Reason I'm asking is, that I want to use one unit as a comparator (save space, reduce cost). Since it's not ideal to use an OpAmp as a comparator I really have to pay attention to these details.
