10 / 22 page Application Hints (Continued) The bias network of the LM124 establishes a drain current which is independent of the magnitude of the power supply voltage over the range of from 3 V DC to 30 VDC. Output short circuits either to ground or to the positive power supply should be of short time duration. Units can be de- stroyed, not as a result of the short circuit current causing metal fusing, but rather due to the large increase in IC chip dissipation which will cause eventual failure due to exces- sive junction temperatures. Putting direct short-circuits on more than one amplifier at a time will increase the total IC power dissipation to destructive levels, if not properly pro- tected with external dissipation limiting resistors in series with the output leads of the amplifiers. The larger value of output source current which is available at 25˚C provides a larger output current capability at elevated temperatures (see typical performance characteristics) than a standard IC op amp. The circuits presented in the section on typical applications emphasize operation on only a single power supply voltage. If complementary power supplies are available, all of the standard op amp circuits can be used. In general, introduc- ing a pseudo-ground (a bias voltage reference of V +/2) will allow operation above and below this value in single power supply systems. Many application circuits are shown which take advantage of the wide input common-mode voltage range which includes ground. In most cases, input biasing is not required and input voltages which range to ground can easily be accommodated. Typical Single-Supply Applications (V+ = 5.0 V DC) Non-Inverting DC Gain (0V Input = 0V Output) 00929905 *R not needed due to temperature independent IIN DC Summing Amplifier (V IN’S ≥ 0V DC and VO ≥ V DC) Power Amplifier 00929906 Where: V0 =V1 +V2 −V3 −V4 (V1 +V2) ≥ (V3 +V4) to keep VO > 0VDC 00929907 V0 =0VDC for VIN =0VDC AV =10 www.national.com 9 |
