LM2924 Datasheet | National Semiconductor

Description The LM392 series consists of 2 independent building block circuits. One is a high gain, internally frequency pensated operational amplifier, and the other is a precision voltage parator. Both the operational amplifier and the voltage parator have been specifically designed to operate from a single power supply over a wide range of voltages. Both circuits have input stages which will mon-mode 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. Application areas include transducer amplifier with pulse shaper, DC gain block with level detector, VCO, as well as all conventional operational amplifier or voltage parator circuits. Both circuits can be operated directly from the standard 5 VDC power supply voltage used in digital systems, and the output of the parator will interface directly with either TTL or CMOS logic. In addition, the low power drain makes the LM392 extremely useful in the design of portable equipment. n Power drain suitable for battery operation n Pin-out is the same as both the LM358 dual op amp and the LM393 dual parator Features n Wide power supply voltage range Single supply: 3V to 32V Dual supply: ± 1.5V to ± 16V n Low supply current drain - essentially independent of supply voltage: 600 µA n Low input biasing current: 50 n A n Low input offset voltage: 2 m V n Low input offset current: 5 n A n Input mon-mode voltage range includes ground n Differential input voltage range equal to the power supply voltage n n n n ADDITIONAL OP AMP FEATURES Internally frequency pensated for unity gain Large DC voltage gain: 100 d B Wide bandwidth (unity gain): 1 MHz Large output voltage swing: 0V to V+ - 1.5V Advantages n Eliminates need for dual power supplies n An internally pensated op amp and a precision parator in the same package n Allows sensing at or near ground ADDITIONAL PARATOR FEATURES n...
