XXX 1 Publication Order Number: LM308A/D LM308A Precision Operational Amplifier The LM308A operational amplifier provides high input impedance, low input offset and temperature drift, and low noise. These characteristics are made possible by use of a special Super Beta processing technology. This amplifier is particularly useful for applications where high accuracy and low drift performance are essential. In addition high speed performance may be improved by employing feedforward compensation techniques to maximize slew rate without compromising other performance criteria. The LM308A offers extremely low input offset voltage and drift specifications allowing usage in even the most critical applications without external offset nulling. • Operation from a Wide Range of Power Supply Voltages • Low Input Bias and Offset Currents • Low Input Offset Voltage and Guaranteed Offset Voltage Drift Performance • High Input Impedance R2 Frequency Compensation Standard Compensation Modified Compensation R2 R1 R3 Compen A Output Compen B Inverting Input Noninverting Input Cf ≥ 30 1 1 + R2 R1 Cf Standard Feedforward Compensation Feedforward Compensations for Decoupling Load Capacitance Input 10k 5.0pF 10 k Output CompenB 3.0k 10pF CompenA 500pF Input 500 10pF C2* Compen B 10pF 500pF 3.0k CL 75pF to 0.01 µF *C2 > 5 x 105 pF R1 R3 Compen B Inverting Input Noninverting Input 100pF R2 RS > 10k 100k 0.01 µF CompenA + + + + Output Device Package Shipping ORDERING INFORMATION LM308AN PDIP−8 50 Units/Rail LM308AD SO−8 http://onsemi.com 98 Units/Rail Compen A Compen B Inputs Output VCC NC VEE (Top View) 1 2 3 4 8 7 6 5 PIN CONNECTIONS + − PDIP−8 N SUFFIX CASE 626 1 8 SO−8 D SUFFIX CASE 751 1 8 MARKING DIAGRAMS ALYWA LM308 1 8 AWL LM308AN 1 8 YYWW A = Assembly Location WL, L = Wafer Lot YY, Y = Year WW, W = Work Week LM308ADR2 SO−8 2500 Tape & Reel |
