Notes:
(1) All voltage values are with respect to GND.
(2) Full-scale frequency is the maximum operating frequency of the device without saturation.
(3) Output interface of device is designed to drive a standard TTL or CMOS logic input over short distances. If lines greater than 12 inches are
used on output, a buffer or line driver is recommended.
OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
