LM158/LM258/LM358/LM2904 Low Power Dual Operational Amplifiers
March 2002
LM158/LM258/LM358/LM2904 Low Power Dual Operational Amplifiers
General Description
The LM158 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, dc gain blocks and all the conventional op amp circuits which now can be more easily implemented in single power supply systems. For example, the LM158 series can be directly operated off of the standard +5V power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional ± 15V power supplies. The LM358 and LM2904 are available in a chip sized package (8-Bump micro SMD) using National's micro SMD package technology.
Advantages
n Two internally compensated op amps n Eliminates need for dual supplies n Allows direct sensing near GND and VOUT also goes to GND n Compatible with all forms of logic n Power drain suitable for battery operation n Pin-out same as LM1558/LM1458 dual op amp
Features
n Available in 8-Bump micro SMD chip sized package, (See AN-1112) n Internally frequency compensated for unity gain n Large dc voltage gain: 100 dB n Wide bandwidth (unity gain): 1 MHz (temperature compensated) n Wide power supply range: -- Single supply: 3V to 32V -- or dual supplies: ± 1.5V to ± 16V n Very low supply current drain (500 µA) -- essentially independent of supply voltage n Low input offset voltage: 2 mV n Input common-mode voltage range includes ground n Differential input voltage range equal to the power supply voltage n Large output voltage swing: 0V to V+- 1.5V
Unique Characteristics
n In the linear mode the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage. n The unity gain cross frequency is temperature compensated. n The input bias current is also temperature compensated.

Note 1: For operating at high temperatures, the LM358/LM358A, LM2904 must be derated based on a +125°C maximum junction temperature and a thermal resistance of 120°C/W for MDIP, 182°C/W for Metal Can, 189°C/W for Small Outline package, and 230°C/W for micro SMD, which applies for the device soldered in a printed circuit board, operating in a still air ambient. The LM258/LM258A and LM158/LM158A can be derated based on a +150°C maximum junction temperature. The dissipation is the total of both amplifiers -- use external resistors, where possible, to allow the amplifier to saturate or to reduce the power which is dissipated in the integrated circuit. Note 2: Short circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short cirucits to ground, the maximum output current is approximately 40 mA independent of the magnitude of V+. At values of supply voltage in excess of +15V, continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers. Note 3: This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the op amps to go to the V+voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was negative, again returns to a value greater than -0.3V (at 25°C). Note 4: These specifications are limited to -55°C TA +125°C for the LM158/LM158A. With the LM258/LM258A, all temperature specifications are limited to -25°C TA +85°C, the LM358/LM358A temperature specifications are limited to 0°C TA +70°C, and the LM2904 specifications are limited to -40°C TA +85°C. Note 5: VO . 1.4V, RS = 0 with V+ from 5V to 30V; and over the full input common-mode range (0V to V+ -1.5V) at 25°C. For LM2904, V+ from 5V to 26V. Note 6: The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output so no loading change exists on the input lines. Note 7: The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (at 25°C). The upper end of the common-mode voltage range is V+ -1.5V (at 25°C), but either or both inputs can go to +32V without damage (+26V for LM2904), independent of the magnitude of V+. Note 8: Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts. This typically can be detected as this type of capacitance increases at higher frequencies. Note 9: Refer to RETS158AX for LM158A military specifications and to RETS158X for LM158 military specifications. Note 10: Human body model, 1.5 k in series with 100 pF.
