Note 5:
The supply current of the LT1259/LT1260 has a negative temperature range. temperature coefficient. See Typical Performance Characteristics.
Note 1:
A heat sink may be required depending on the power supply
Note 6:
Slew rate is measured at ±5V on a ±10V output signal while voltage and how many amplifiers have their outputs short circuited. operating on ±15V supplies with RF = 1k, RG = 110Ω and RL = 1k.
Note 2:
Commercial grade parts are designed to operate over the

Turn-on delay time is measured while operating on ±5V temperature range of – 40°C to 85°C but are neither tested nor guaranteed supplies with RF = 1k, RG = 110Ω and RL = 150Ω. The tON is measured beyond 0°C to 70°C. Industrial grade parts specified and tested over from control input to appearance of 0.5V at the output, for VIN = 0.1V. – 40°C to 85°C are available on special request. Consult factory. Likewise, turn-off delay time is measured from control input to

Ground pins are not internally connected. For best appearance of 0.5V on the output for VIN = 0.1V. performance, connect to ground.
Note 8:
Differential gain and phase are measured using a Tektronix
Note 4:
TJ is calculated from the ambient temperature TA and the TSG120YC/NTSC signal generator and a Tektronix 1780R Video power dissipation PD according to the following formulas: Measurement Set. The resolution of this equipment is 0.1% and 0.1°.
