NOTES
1
Propagation delay measured from the 50% of the rising/falling transition of WRITE PULSE to 50% point of the rising/falling edge of the output modulation current.
2
Rise time measured between the 10% and 90% points of the rising transition of the modulation current.
3
Fall time measured between the 10% and 90% points of the falling transition of the modulation current.
4
Aperture Delay is measured from the 50% point of the rising edge of WRITE PULSE to the time when the output modulation begins to recalibrate, WRITE CAL is
held during this test.
5
Disable Time is measured from the 50% point of the rising edge of DISABLE to the 50% point of the falling transition of the output current. Fall time during disable
is similar to fall time during normal operation.
6
WRITE PULSE, WRITE CAL, BIAS CAL, OFFSET PULSE are TTL compatible inputs.
Specifications subject to change without notice.
