AD7741–SPECIFICATIONS
Temperature ranges: B Version –40 C to +85 C: Y Version: –40 C to +105 C.
See Terminology.
Guaranteed by design and characterization, not production tested.
Span = Maximum Output Frequency–Minimum Output Frequency.
The absolute voltage on the input pin must not go more positive than V
Because this pin is bidirectional, any external reference must be capable of sinking/sourcing 400 A in order to overdrive the internal reference.
These logic levels apply to CLKOUT only when it is loaded with one CMOS load.
