LM392-N www.ti.com SNOSBT5D – APRIL 1998 – REVISED MARCH 2013 lm392-N Low Power Operational Amplifier/Voltage Comparator Check for Samples: LM392-N FEATURES DESCRIPTION • The lm392-N series consists of 2 independent building block circuits. One is a high gain, internally frequency compensated operational amplifier, and the other is a precision voltage comparator. Both the operational amplifier and the voltage comparator have been specifically designed to operate from a single power supply over a wide range of voltages. Both circuits have input stages which will commonmode input down to ground when operating from a single power supply. Operation from split power supplies is also possible and the low power supply current is independent of the magnitude of the supply voltage. 1 2 • • • • • • • • Wide Power Supply Voltage Range – Single Supply: 3V to 32V – Dual Supply: ±1.5V to ±16V Low Supply Current Drain—Essentially Independent of Supply Voltage: 600 μA Low Input Biasing Current: 50 nA Low Input Offset Voltage: 2 mV Low Input Offset Current: 5 nA Input Common-Mode Voltage Range Includes Ground Differential Input Voltage Range Equal to the Power Supply Voltage ADDITIONAL OP AMP FEATURES – Internally Frequency Compensated for Unity Gain – Large DC Voltage Gain: 100 dB – Wide Bandwidth (Unity Gain): 1 MHz – Large Output Voltage Swing: 0V to V+ − 1.5V ADDITIONAL COMPARATOR FEATURES – Low Output Saturation Voltage: 250 mV at 4 mA – Output Voltage Compatible with all Types of Logic Systems Application areas include transducer amplifier with pulse shaper, DC gain block with level detector, VCO, as well as all conventional operational amplifier or voltage comparator circuits. Both circuits can be operated directly from the standard 5 VDC power supply voltage used in digital systems, and the output of the comparator will interface directly with either TTL or CMOS logic. In addition, the low power drain makes the lm392-N extremely useful in the design of portable equipment.

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications. For operating at temperatures above 25°C, the lm392-N must be derated based on a 125°C maximum junction temperature and a thermal resistance of 122°C/W which applies for the device soldered in a printed circuit board, operating in still air ambient. 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. Short circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short circuits to ground, the maximum output current is approximately 40 mA for the op amp and 30 mA for the comparator 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. 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 amplifiers 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).

For the lm392-N, temperature specifications are limited to 0°C ≤ TA ≤ +70°C. At output switch point, VO ≃ 1.4V, RS = 0Ω with V+ from 5V to 30V; and over the full input common-mode range (0V to V+ − 1.5V). 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. The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is V+ − 1.5V, but either or both inputs can go to 32V without damage.

This typically can be detected as this type of capacitive coupling increases at higher frequencies. Positive excursions of input voltage may exceed the power supply level. As long as the other input voltage remains within the commonmode range, the comparator will provide a proper output state. The input voltage to the op amp should not exceed the power supply level. The input voltage state must not be less than −0.3V (or 0.3V below the magnitude of the negative power supply, if used) on either amplifier. The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be obtained.
