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

Note 7: Turn-on delay time is measured while operating on

±5V

Likewise, turn-off delay time is measured from control input to

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

°.
