NOTES
1At fMAX = 250 kHz; RT = 1 kΩ, CT = 390 pF, IIN = 0 mA—1 mA. fMAX = 500 kHz; RT = 1 kΩ, CT = 200 pF, IIN = 0 mA—1 mA.
2The sink current is the amount of current that can flow into Pin 1 of the AD654 while maintaining a maximum voltage of 0.4 V between Pin 1 and Logic Common.
Specifications shown in boldface are tested on all production units at final electrical test. Results from those tests are used to calculate outgoing quality levels. All min and max specifications are guaranteed, although only those shown in boldface are tested on all production units.
Specifications subject to change without notice.
