ELECTRICAL CHARACTERISTICS
The
temperature range.
Note 1: A heat sink may be required depending on the power supply
voltage and how many amplifiers have their outputs short circuited.
Note 2: Commercial grade parts are designed to operate over the
temperature range of – 40 C to 85 C but are neither tested nor guaranteed
beyond 0 C to 70 C. Industrial grade parts specified and tested over
– 40 C to 85 C are available on special request. Consult factory.
Note 3: Ground pins are not internally connected. For best
performance, connect to ground.

Note 5: The supply current of the LT1259/LT1260 has a negative
temperature coefficient. See Typical Performance Characteristics.
Note 6: Slew rate is measured at 5V on a 10V output signal while
operating on 15V supplies with R
Note 7: Turn-on delay time is measured while operating on 5V
supplies with R
from control input to appearance of 0.5V at the output, for V
Likewise, turn-off delay time is measured from control input to
appearance of 0.5V on the output for V
Note 8: Differential gain and phase are measured using a Tektronix
TSG120YC/NTSC signal generator and a Tektronix 1780R Video
Measurement Set. The resolution of this equipment is 0.1% and 0.1 .
Six identical amplifier stages were cascaded giving an effective
resolution of 0.016% and 0.016 .
