These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltage values, except differential voltages, are with respect to the midpoint between VCC+ and VCC–. The magnitude of the input voltage must never exceed the magnitude of the supply voltage. Excessive input current will flow if a differential input voltage in excess of approximately 0.6 V is applied between the inputs, unless some limiting resistance is used. The output may be shorted to ground or either power supply. Temperature and/or supply voltages must be limited to ensure the maximum dissipation rating is not exceeded. 7.2 Handling Ratings PARAMETER Tstg MIN MAX UNIT °C Storage temperature range V(ESD) (1) (2) DEFINITION –65 150 Human-Body Model (HBM) (1) 0 2.5 Charged-Device Model (CDM) (2) 0 1.5 kV JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA) / θJA. Operating at the absolute maximum TJ of 150°C can affect reliability. The package thermal impedance is calculated in accordance with JESD 51-7.

This device operates over a wide range of single- and dual-supply voltage with low noise, high-gain bandwidth, and high slew rate. Additional features include low total harmonic distortion, excellent phase and gain margins, large output voltage swing with no deadband crossover distortions, and symmetrical sink/source performance. The dual amplifiers are utilized widely in circuit of audio optimized for all preamp and high-level stages in PCM and HiFi systems. The LM833 device is pin-for-pin compatible with industry-standard dual operation amplifiers' pin assignments. With addition of a preamplifier, the gain of the power stage can be greatly reduced to improve performance. 8.2 Functional Block Diagram VCC INí IN+ VOUT VEE Submit Documentation Feedback Copyright © 2010–2014, Texas Instruments Incorporated Product Folder Links: LM833 13 LM833 SLOS481B – JULY 2010 – REVISED OCTOBER 2014 www.ti.com 8.3 Feature Description 8.3.1 Operating Voltage The LM833 operational amplifier is fully specified and ensured for operation from ±5 V to ±18 V. In addition, many specifications apply from –40°C to 85°C. Parameters that vary significantly with operating voltages or temperature are shown in Absolute Maximum Ratings . 8.3.2 High Gain Bandwidth Product Gain bandwidth product is found by multiplying the measured bandwidth of an amplifier by the gain at which that bandwidth was measured. The LM833 has a high gain bandwidth of 16 MHz which stays relatively stable over a wide range of supply voltages. Parameters that vary significantly with temperature are shown in Figure 14. 8.3.3 Low Total Harmonic Distortion Harmonic distortions to an audio signal are created by electronic components in a circuit. Total harmonic distortion (THD) is a measure of harmonic distortions accumulated by a signal in an audio system. The LM833 has a very low THD of 0.002% meaning that the LM833 will add little harmonic distortion when used in audio signal applications. More specific characteristics are shown in Figure 22. 8.4 Device Functional Modes The LM833 is powered on when the supply is connected. It can be operated as a single supply operational amplifier or dual supply amplifier depending on the application. 14 Submit Documentation Feedback Copyright © 2010–2014, Texas Instruments Incorporated Product Folder Links: LM833 LM833 www.ti.com SLOS481B – JULY 2010 – REVISED OCTOBER 2014 9 Application and Implementation NOTE Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information An application of the LM833 is the two stage RIAA Phono Preamplifier. A primary task of the phono preamplifier is to provide gain (usually 30 to 40 dB at 1 kHz) and accurate amplitude and phase equalization to the signal from a moving magnet or a moving coil cartridge. In addition to the amplification and equalization functions, the phono preamp must not add significant noise or distortion to the signal from the cartridge. The circuit shown in Figure 36 uses two amplifiers, fulfills these qualifications, and has greatly improved performance over a singleamplifier design. 9.2 Typical Application VIN 47 k CP ½ LM833 3 + 2 1 R3 2.37 C4 2 PF 4 C3 33 nF -15 V R1 80.6 k 15 V R6 54.9 k R2 8.45 k R4 2 k R0 499 5 + 8 6 7 VOUT ½ LM833 R5 4.3 k C1 39 nF C0 200 PF Figure 36.

THD of Circuit in Figure 36 as a Function of Frequency 9.3 Typical Application — Reducing Oscillation from High-Capacitive Loads While all the previously stated operating characteristics are specified with 100-pF load capacitance, the LM833 device can drive higher-capacitance loads. However, as the load capacitance increases, the resulting response pole occurs at lower frequencies, causing ringing, peaking, or oscillation. The value of the load capacitance at which oscillation occurs varies from lot-to-lot. If an application appears to be sensitive to oscillation due to load capacitance, adding a small resistance in series with the load should alleviate the problem (see Figure 39). 9.3.1 Test Schematic 15 V RO VO 5V –5 V –15 V CL RL = 2 kΩ Figure 39.

The Typical Characteristics section presents parameters that can exhibit significant variance with regard to operating voltage or temperature. CAUTION Supply voltages larger than 36 V can permanently damage the device (see Absolute Maximum Ratings ). Place 0.1-μF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or high impedance power supplies. For more detailed information on bypass capacitor placement, refer to the Layout section. 11 Layout 11.1 Layout Guidelines For best operational performance of the device, use good PCB layout practices, including: • Noise can propagate into analog circuitry through the power pins of the circuit as a whole and the operational amplifier. Bypass capacitors are used to reduce the coupled noise by providing low impedance power sources local to the analog circuitry. – Connect low-ESR, 0.1-μF ceramic bypass capacitors between each supply pin and ground, placed as close to the device as possible. A single bypass capacitor from V+ to ground is applicable for single supply applications. • Separate grounding for analog and digital portions of circuitry is one of the simplest and most-effective methods of noise suppression. One or more layers on multilayer PCBs are usually devoted to ground planes. A ground plane helps distribute heat and reduces EMI noise pickup. Make sure to physically separate digital and analog grounds, paying attention to the flow of the ground current. For more detailed information, refer to Circuit Board Layout Techniques, (SLOA089). • To reduce parasitic coupling, run the input traces as far away from the supply or output traces as possible. If it is not possible to keep them separate, it is much better to cross the sensitive trace perpendicular as opposed to in parallel with the noisy trace. • Place the external components as close to the device as possible. Keeping RF and RG close to the inverting input minimizes parasitic capacitance, as shown in Layout Example. • Keep the length of input traces as short as possible. Always remember that the input traces are the most sensitive part of the circuit. • Consider a driven, low-impedance guard ring around the critical traces. A guard ring can significantly reduce leakage currents from nearby traces that are at different potentials. 11.2 Layout Example VIN RIN RG + VOUT RF Figure 46.
