TIGER ELECTRONIC CO.,LTD LM2902N/D QUAD OPERATIONAL AMPLIFIER LM2902 Outline Drawing DESCRIPTION The LM2902 consist of four independent, high gain, internally frequency comp ensated operational amplifiers which were designed LM2902N specifically to operate from a single power supply over a wide voltage range. 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 amplifier, DC gain DIP14 blocks and all the conventional OP amp circuits which now can be easily implemented in single power LM2902D supply systems. FEATURE Large DC voltage gain: 100dB Wide power supply range: Vcc=3V~32V(or Vcc=±1.5V~±1 6 V) SOP1 4 Input common-mode voltage range includes ground. Large output voltage swing :0V~Vcc-1.5V Power drain suitable for battery operation Internally frequency comp ensated for unity gain Wide bandwidth(unity gain) 1MHz Very low supply current drain(700µA)—essentially independent of supply voltage Low input biasing current Low input offset voltage 45nA 2mV and offset current 5nA Differential input voltage range equal to the power supply voltage Compatible with all forms of logic 1/5 LM2902N/D SCHEMATIC DIAGRAM INTERNAL BLOCK DIAGRAM AND PIN CONNECTION OUT1 1 IN1( - ) 2 14 OUT4 1 - + IN1( + ) 3 4 + - 12 IN4( + ) 11 GND Vcc 4 IN2( + ) 5 10 IN3( + ) + 2 OUT2 7 - + IN2( - ) 6 13 IN4( - ) 3 9 IN3( - ) 8 OUT3 ABSOLUTE MAXIMUM RATINGS (Ta=25 °C) Characteristic Power Supply Voltage Differential Input Voltage Input Voltage Output Short Circuit to GND DIP14 SOP14 Operating Temperature Range Storage Temp erature Power Dissipation Symbol Vcc VID VIN PD Topr Tstg Value ±16 or 32 32 -0.3~32 Continuous 1130 800 -20~+85 -65~150 Unit V V V mW °C °C 2/5 LM2902N/D ELECTRICAL CHARACTERISTICS (unless otherwise specified: Ta=25°C, Vcc=5V) Characteristics Test Conditions Min.
