IC CA3130 Circuit

Published:2013-12-2 21:03:00 Author:lynne | Keyword: IC CA3130 Circuit

IC CA3130 Circuit
CA3130A and CA3130 are op amps that combine the advantage of both CMOS and bipolar transistors. Gate-protected P-Channel MOSFET (PMOS) transistors are used in the input circuit to provide very-high-input impedance, very-low-input current, and exceptional speed performance. The use of PMOS transistors in the input stage results in common-mode input-voltage capability down to 0.5V below the negative-supply terminal, an important attribute in single-supply applications.The CA3130 Series circuits operate at supply voltages ranging from 5V to 16V, (±2.5V to ±8V). They can be phase compensated with a single external capacitor, and have terminals for adjustment of offset voltage for applications requiring offset-null capability. Terminal provisions are also made to permit strobing of the output stage. The CA3130A offers superior input characteristics over those of the CA3130.   (View)

TL071, TL072, TL074 Circuit
The JFET-input operational amplifiers in the TL07x series are similar to the TL08x series, with low input bias and offset currents and fast slew rate. The low harmonic distortion and low noise make the TL07x series ideally suited for high-fidelity and audio preamplifier applications. Each amplifier features JFET inputs (for high input impedance) coupled with bipolar output stages integrated on a single monolithic chip.TL071, TL072, TL074 Pinout   (View)

Hi-Fi Stereo Preamp Circuit

Published:2013-11-28 20:56:00 Author:lynne | Keyword: Hi-Fi Stereo Preamp Circuit

Hi-Fi Stereo Preamp Circuit
This Hi Fi stereo preamplifier circuit is built with TDA1054 IC from SGS. TDA1054 is a 16-pin DIL package and integrates 2 separate preamp circuits.It is a low noise preamp with little or no problem in the building process.The first half of the circuit (IC1a) it has an input sensitivity of 3 mV and has a frequency correction composed of C5, C3, R6 and R8. The bass signal coming from phono input is amplified while the high signal is attenuated. The selection of the input signal sources is done with switch S1. P1 and P2 are parte of a double potentiometer. They control the high tones and bass. There is no risk of overdrive in circuit due to the passive nature of the sound control. P3 controls the volume of the signal fed to se second part of the circuit (IC1b) which functions as an operational amplifier. P4 controls the balance between the left and right channels but in the schematic is shown only the preamp for one channel.Both channel have a gain of 24 at the middle setting of P4. If P4 is set to one extreme end, the gain difference between the 2 channels is about 12 dB. HiFi stereo preamplifier schematic   (View)

LM317 Audio Amplifier Circuit
You probably know that LM317 IC is used as an adjustable voltage regulator, but did you know it can be used as an audio amplifier? This is a class A audio amplifier built with LM317 that delivers a maximum 1W audio power. Use a good heatsink for the LM317 IC and adjust the 5K variable resistor so that you have 4.5V on 10Ω resistor (or LM317 pin 2, Vout). LM317 amplifier schematic   (View)
