Slew rate is measured at ±2V on a ±3V output signal. of a device may be impaired.
Note 7:
Turn-on delay time (tON) is measured from control input to
Note 2:
This parameter is guaranteed to meet specified performance appearance of 1V at the output, for VIN = 1V. Likewise, turn-off delay through design and characterization. It has not been tested. time (tOFF) is measured from control input to appearance of 0.5V on

The LT1398C/LT1399C/LT1399HVC are guaranteed to meet
Note 8:
Differential gain and phase are measured using a Tektronix specified performance from 0°C to 70°C and are designed, characterized TSG120YC/NTSC signal generator and a Tektronix 1780R Video and expected to meet these extended temperature limits, but are not tested Measurement Set. The resolution of this equipment is 0.1% and 0.1°. or QA sampled at – 40°C and 85°C. The LT1399I is guaranteed to meet Ten identical amplifier stages were cascaded giving an effective specified performance from –40°C to 85°C. resolution of 0.01% and 0.01°.
