Powered from symmetrical ±15 V rails, the circuit operates in an inverting configuration with closed-loop voltage gain Av = -RF \u002F RI = -47 kΩ \u002F 1 kΩ = -47 V\u002FV (+33.44 dB, 180° phase inversion). Setting input resistor R1 to 1 kΩ matches dynamic microphone capsules while suppressing the op-amp input noise current contribution (0.7 pA\u002F√Hz). Input DC blocking capacitor C1 (10 µF) forms a 15.9 Hz high-pass corner, eliminating phantom bias or transducer DC currents from shifting the internal summing node. Phase compensation capacitor C2 (47 pF C0G) shunts feedback resistor R2 above 72 kHz, guaranteeing high-frequency stability and blocking RF interference without compromising audio fidelity. The non-inverting input (pin 3) is referenced to ground via DC bias resistor R3 (1 kΩ) to equalize input bias current voltage drops, while capacitor C3 (10 µF) provides an AC noise ground. Series resistor R4 (47 Ω) isolates the op-amp output from capacitive cable loading, and output capacitor C6 (10 µF) ensures clean DC-isolated line-level delivery.","### 1. Symmetrical dual power rails and dynamic headroom\nThe NE5532 operational amplifier is energized from symmetrical ±15 V regulated rails (+15 V on pin 8, -15 V on pin 4). These split rails permit the internal Class-AB output stage to swing symmetrical AC audio waveforms up to ±13.5 V peak-to-peak into standard loads without DC rail biasing. Symmetrical supplies eliminate crossover distortion artifacts and maintain wide dynamic range exceeding 110 dB.\n\n### 2. Virtual ground summing node and inverting gain\nThe non-inverting input (pin 3) is held at 0 V DC ground potential. Because the NE5532 exhibits high open-loop DC voltage gain (A_OL ≈ 100 dB) and wide 10 MHz unity-gain bandwidth, negative feedback forces the inverting terminal (pin 2) to match pin 3, creating an ideal virtual ground node at 0 V. Signal current generated by the microphone flows across input resistor R1 (1 kΩ) directly into the feedback network. The closed-loop AC voltage gain is governed strictly by the resistor ratio:\n$$A_V = -\\frac{R_F}{R_I} = -\\frac{47\\text{ k}\\Omega}{1\\text{ k}\\Omega} = -47\\text{ V\u002FV}$$\nIn decibels, this corresponds to $20 \\log_{10}(47) \\approx +33.44\\text{ dB}$ of clean voltage gain with 180° phase inversion.\n\n### 3. AC coupling and low-frequency cutoff\nDirect current is blocked from the input transducer by series capacitor C1 (10 µF). Together with input resistor R1 (1 kΩ), capacitor C1 establishes a single-pole high-pass transfer characteristic with a -3 dB low-frequency cutoff frequency:\n$$f_L = \\frac{1}{2\\pi \\cdot R_I \\cdot C_1} = \\frac{1}{2\\pi \\cdot 1000\\,\\Omega \\cdot 10 \\times 10^{-6}\\text{ F}} \\approx 15.9\\text{ Hz}$$\nThis cutoff passes the full audible bass spectrum down to 20 Hz with less than 0.8 dB attenuation and prevents low-frequency subsonic handling rumble from driving the amplifier into saturation.\n\n### 4. Ultrasonic phase compensation and bandwidth limiting\nIn parallel with feedback resistor R2, ceramic capacitor C2 (47 pF C0G) introduces a feedback zero that rolls off circuit gain above the audible range:\n$$f_H = \\frac{1}{2\\pi \\cdot R_F \\cdot C_F} = \\frac{1}{2\\pi \\cdot 47000\\,\\Omega \\cdot 47 \\times 10^{-12}\\text{ F}} \\approx 72.0\\text{ kHz}$$\nRestricting high-frequency gain prevents RF interference from mobile transmitters and switch-mode power supplies from entering the feedback loop, preserving wide phase margin and ensuring unconditional stability under all operating conditions.\n\n### 5. Input bias equalization and output cable isolation\nThe NE5532 bipolar input stage draws input bias currents (I_B ≈ 200 nA typical) through both differential bases. Non-inverting input resistor R3 (1 kΩ) matches the DC source resistance seen by the inverting node (R1 || R2 ≈ 980 Ω), cancelling input offset voltage drift. Capacitor C3 (10 µF) shorts R3 thermal noise to ground at audio frequencies (> 16 Hz). At the output, isolation resistor R4 (47 Ω) de-Q's any capacitive reactance from external interconnect cables, preventing high-frequency output ringing while output capacitor C6 (10 µF) delivers a pristine DC-isolated audio signal.",[26,29,32,35,38,41,44,47],{"label":27,"value":28},"Closed-Loop AC Gain (Av)","-47 V\u002FV (+33.44 dB, 180° phase inversion)",{"label":30,"value":31},"Input Resistor (RI \u002F R1)","1 kΩ, 1%, 0.125 W metal film",{"label":33,"value":34},"Feedback Resistor (RF \u002F R2)","47 kΩ, 1%, 0.125 W metal film",{"label":36,"value":37},"Frequency Response (-3 dB)","15.9 Hz to 72.0 kHz",{"label":39,"value":40},"Equivalent Input Noise Voltage","≈ 6.5 nV\u002F√Hz total (5.0 nV\u002F√Hz op-amp broadband)",{"label":42,"value":43},"Power Supply Rails (V+ \u002F V-)","±15 V symmetrical split supply (±3 V to ±20 V)",{"label":45,"value":46},"Input Impedance (ZIN)","1 kΩ (set by R1 at virtual ground node)",{"label":48,"value":49},"Output Drive Capability","Up to ±38 mA short-circuit current, drives 600 Ω loads",[51,52,53,54],"Studio and live-sound dynamic microphone preamplification (150 Ω to 600 Ω transducers)","Low-noise active audio mixer summing and channel gain stage","Balanced audio line receiver and instrumentation acoustic sensing interface","High-fidelity educational reference benchmark for low-noise bipolar operational amplifiers",[56,61,66,70],{"title":57,"trap":58,"solution":59,"severity":60},"Excessive Source Impedance Noise Penalty","Because the NE5532 has a bipolar input stage with an input noise current density of 0.7 pA\u002F√Hz, using source or input resistances above 10 kΩ causes current-induced noise voltage (i_n · R) and resistor Johnson noise to overpower the low 5 nV\u002F√Hz voltage noise.","Keep input resistor R1 at or below 1 kΩ and ensure driving transducer impedance is low (150 Ω to 600 Ω).
