LT1259/LT1260
The q denotes specifications which apply over the specified operating
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 4: TJ is calculated from the ambient temperature TA and the
power dissipation PD according to the following formulas:
LT1259CN/LT1259IN: TJ = TA + (PD 70°C/W)
LT1259CS/LT1259IS: TJ = TA + (PD 110°C/W)
LT1260CNLT1260IN/: TJ = TA + (PD 70°C/W)
LT1260CS/LT1260IS: TJ = TA + (PD 100°C/W)
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 RF = 1k, RG = 110 and RL = 1k.
Note 7: Turn-on delay time is measured while operating on
±5V
supplies with RF = 1k, RG = 110 and RL = 150. The tON is measured
from control input to appearance of 0.5V at the output, for VIN = 0.1V.
Likewise, turn-off delay time is measured from control input to
appearance of 0.5V on the output for VIN = 0.1V.
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
°.
