SL4558 Dual Operational Amplifiers The SL4558 is dual general purpose operational amplifiers. The high common-mode input voltage range and the absence of latch-up make these amplifiers ideal for voltage follower application. The devices are short circuit protected and the internal frequency compensation ensures stability without external components. • • • • • • • Short-Circuit Protection Wide common-mode and differential ranges No frequency compensation required Low power consumption No latch-up 3 MHz unity gain bandwidth guaranteed Gain and phase math between amplifiers ORDERING INFORMATION SL4558N Plastic SL4558D SOIC TA = 0° to 70° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM Pin 4 = Supply Voltage VPin 8 = Supply Voltage V+ SLS System Logic Semiconductor SL4558 MAXIMUM RATINGS * Symbol Value Unit Supply Voltage +18 V Supply Voltage -18 V VIDR Differential Input Voltage ±30 V VIN Input Voltage ±15 V PD Power Dissipation in Still Air 570 mW Tstg Storage Temperature Range -55 to +125 °C + V - V Parameter * Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the Recommended Operating Conditions. RECOMMENDED OPERATING CONDITIONS Symbol Parameter Min Max Unit V+ Supply Voltage +15 V - V Supply Voltage -15 V TA Operating Temperature, All Pakage Types +70 °C 0 This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.
