4 Pieces | TI RC4558P 4558 Dual Operational Amplifier DIP-8

Description: How to use RC4558?The operation of this IC is explained through a voltage controlled oscillator circuit which is given below. The voltage-controlled oscillator can be designed through two op-amps. Instead of using two op-amps, you can use the RC4558 IC. The voltage to be controlled is applied at the input pin2. Due to the network of a voltage divider connected between pins2 and 3, half of this voltage is applied at pin3.Voltage Controlled Oscillator Example CircuitThe op-amp A will generate a triangular waveform on powering the IC. The current will flow from the 100k resistor and then discharges the 0.05µF capacitor resulting in a triangular wave at its output. This output is connected to the input pin of the op-amp B through a 51kΩ resistor. The op-amp works B as a Schmitt trigger. It monitors the input voltage. When the input voltage is above the threshold level, then it will send a HIGH signal at output and if the input voltage falls below the threshold level, the output will become zero. In this way, a square wave is produced at the output. 1 FeaturesContinuous Short-Circuit ProtectionWide Common-Mode and Differential Voltage RangesNo Frequency Compensation RequiredLow Power ConsumptionNo Latch-UpUnity-Gain Bandwidth: 3 MHz TypGain and Phase Match Between AmplifiersLow Noise: 8 nV/√Hz Typ at 1 kHz2 ApplicationsDVD Recorders and PlayersPro Audio Mixers3 DescriptionThe RC4558 device is a dual general-purpose operational amplifier, with each half electrically similar to the μA741, except that offset null capability is not provided.The high common-mode input voltage range and the absence of latch-up make this amplifier ideal for voltage-follower applications. The device is short-circuit protected, and the internal frequency compensation ensures stability without external components.Device Information(1)PART NUMBERPACKAGE (PIN)BODY SIZERC4558SOIC (8)4.90 mm × 3.91 mmSOIC (8)3.00 mm × 3.00 mmPDIP (8)9.81 mm × 6.35 mmTSSOP (8)3.00 mm × 4.40 mmSOP (8)6.20 mm × 5.30 mmFor all available packages, see the orderable addendum at the end of the datasheet.Noninverting Amplifier Schematic4 Revision HistoryChanges from F Revision (September 2010) to G RevisionAdded Applications, Device Information table, Handling Ratings table, Feature Description section, Device Functional Modes, Application and Implementation section, Power Supply Recommendations section, Layout section, Device and Documentation Support section, and Mechanical, Packaging, and Orderable Information section.GoRemoved Ordering Information table.Go5 Pin Configuration and FunctionsPin FunctionsPINTYPEDESCRIPTIONNAMENO.1IN+3INoninverting input1IN-2IInverting Input1OUT1OOutput2IN+5INoninverting input2IN-6IInverting Input2OUT7OOutputVCC+8—Positive SupplyVCC-4—Negative Supply
