Technical content
Dual Operational Amplifiers The IL4558 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 IL4558

MAXIMUM RATINGS* Symbol Parameter Value Unit V+ Supply Voltage +18 V 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 * 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 0 +70 °C 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, V IN and V OUT 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 V CC). Unused outputs must be left open.
