LM2902EP Datasheet | National Semiconductor

Description The LM2902 consists of four independent, high gain, internally frequency pensated 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 LM2902 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. ENHANCED PLASTIC - Extended Temperature Performance of - 40˚C to +85˚C - Baseline Control - Single Fab & Assembly Site - Process Change Notification (PCN) - Qualification & Reliability Data - Solder (Pb Sn) Lead Finish is standard - Enhanced Diminishing Manufacturing Sources (DMS) Support Unique Characteristics n In the linear mode the input mon-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 pensated n The input bias current is also temperature pensated Advantages n Eliminates need for dual supplies n Four internally pensated op amps in a single package n Allows directly sensing near GND and VOUT also goes to GND n patible with all forms of logic n Power drain suitable for battery operation Features n Internally frequency pensated for unity gain n Large DC voltage gain 100 d B n Wide bandwidth (unity gain) 1 MHz (temperature pensated) n Wide power supply range: Single supply 3V to 26V or dual supplies ±1.5V to ±13V n Very low supply current drain (700 µA) - essentially independent of supply voltage n Low input biasing current 45 n A (temperature...
