NOTES

1Propagation 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.

2Rise time measured between the 10% and 90% points of the rising transition of the modulation current.

3Fall time measured between the 10% and 90% points of the falling transition of the modulation current.

4Aperture 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.

5Disable 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.

6WRITE PULSE, WRITE CAL, BIAS CAL, OFFSET PULSE are TTL compatible inputs.

Specifications subject to change without notice.
