Note 1: A heat sink may be required depending on the power supply voltage. 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: TJ is calculated from the ambient temperature TA and the power dissipation PD according to the following formulas: LT1251CN/LT1256CN: TJ = TA + (PD • 70°C/W) LT1251CS/LT1256CS: TJ = TA + (PD • 100°C/W) Note 4: 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 °. Five identical amplifier stages were cascaded giving an effective resolution of 0.02% and 0.02 °. Note 5: Differential gain and phase are best when the control is set at 0% or 100%. See the Typical Performance Characteristics curves. Note 6: Tested with RL = 150Ω to 2.5V to simulate an AC coupled load. Note 7: Small-signal control path response is measured driving RC (Pin 5) to eliminate peaking caused by stray capacitance on Pin 4. |
