| TECHNICAL DATA IL4558 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 ORDERING INFORMATION IL4558N Plastic IL4558D SOIC TA = 0 to 70 C for all packages PIN ASSIGNMENT LOGIC DIAGRAM Pin 4 = Supply Voltage VPin 8 = Supply Voltage V+ 1 IL4558 MAXIMUM RATINGS* Symbol V + - Parameter Supply Voltage Supply Voltage Differential Input Voltage Input Voltage Power Dissipation in Still Air Storage Temperature Range Value +18 -18 30 15 570 -55 to +125 Unit V V V V mW C V VIDR VIN PD Tstg * 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 V + - Parameter Supply Voltage Supply Voltage Operating Temperature, All Pakage Types Min Max +15 -15 Unit V V C V TA 0 +70 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. 2 IL4558 ELECTRICAL CHARACTERISTICS(TA = 0 to +70C, V+ = +15 V, V- = -15 V) Symbol VIO IIO IIB ri AV VOM VICR CMRR PSRR I+, ISR PC VN Isource Isink Parameter Input Offset Voltage Input Offset Current Input Bias Current Input Resistance Large-Signal Voltage Gain Output Voltage Swing RL 2 K, VC = 10 V RL 10 K RL 2 K Input Common-Mode Voltage Range Common Mode Rejection Ratio Supply Voltage Rejection Ratio Supply Current Slew Rate Power Consumption Input Noise Voltage Sourse Current Sink Current RL = 2 K RL = RS = 1 K f = 30 Hz 30 KHz - 20 20 2.5 170 RS 10 K RS 10 K 0.3 20 12 10 12 70 150 5.6 Test Conditions RS 10 K Guaranteed Limits Min Typ Max 5.0 200 - 500 mV nA nA M V/mV V V V dB V/V mA V/s mW Vrms mA mA Unit TYPICAL PERFORMANCE CURVES VOp-p - RL PREQUENCY f (Hz) VNI - f LOAD RESISTANCE RL (k) VOM - VCC, VEE 3 IL4558 FRQUENCY f (Hz) SUPPLY VOLTAGE V+, V- (V) VOp-p- f II - T A FRQUENCY f (Hz) AMBIENT TEMPERATURE TA (C) Schematic Diagram (Each Amplifier) 4 |
