LM7301 www.ti.com SNOS879H – AUGUST 1999 – REVISED MARCH 2013 STABILITY CONSIDERATIONS Rail-to-rail output amplifiers like the LM7301 use the collector of the drive transistor(s) at the output pin, as shown in Figure 29. This allows the load to be driven as close as possible towards either supply rail. V+ + OUT VHZ Ccomp + V- Figure 29.

LM7301 SNOS879H – AUGUST 1999 – REVISED MARCH 2013 www.ti.com POWER DISSIPATION Although the LM7301 has internal output current limiting, shorting the output to ground when operating on a +30V power supply will cause the op amp to dissipate about 350 mW. This is a worst-case example. In the 8-pin SOIC package, this will cause a temperature rise of 58°C. In the 5-pin SOT-23 package, the higher thermal resistance will cause a calculated rise of 113°C.

LM7301 www.ti.com SNOS879H – AUGUST 1999 – REVISED MARCH 2013 OPTICAL LINE ISOLATION FOR MODEMS The combination of the low distortion and good load driving capabilities of the LM7301 make it an excellent choice for driving opto-coupler circuits to achieve line isolation for modems. This technique prevents telephone line noise from coupling onto the modem signal.
