LM4562MA

LM4562 Dual High Performance, High Fidelity Audio Operational Amplifier August 2006 LM4562 Dual High Performance, High Fidelity Audio Operational Amplifier General Description The LM4562 is part of the ultra-low distortion, low noise, high slew rate operational amplifier series optimized and fully specified for high performance, high fidelity applications. Combining advanced leading-edge process technology with state-of-the-art circuit design, the LM4562 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance. The LM4562 combines extremely low voltage noise density (2.7nV/√Hz) with vanishingly low THD+N (0.00003%) to easily satisfy the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LM4562 has a high slew rate of ± 20V/µs and an output current capability of ± 26mA. Further, dynamic range is maximized by an output stage that drives 2kΩ loads to within 1V of either power supply voltage and to within 1.4V when driving 600Ω loads. The LM4562’s outstanding CMRR (120dB), PSRR (120dB), and VOS (0.1mV) give the amplifier excellent operational amplifier DC performance. The LM4562 has a wide supply range of ± 2.5V to ± 17V. Over this supply range the LM4562’s input circuitry maintains excellent common-mode and power supply rejection, as well as maintaining its low input bias current. The LM4562 is unity gain stable. This Audio Operational Amplifier achieves outstanding AC performance while driving complex loads with values as high as 100pF. The LM4562 is available in 8–lead narrow body SOIC, 8–lead Plastic DIP and 8–lead Metal Can TO-99. Demonstration boards are available for each package. j THD+N (AV = 1, VOUT = 3VRMS, fIN = 1kHz) RL = 2kΩ RL = 600Ω j Input Noise Density j Slew Rate j Gain Bandwidth Product j Open Loop Gain (RL = 600Ω) j Input Bias Current j Input Offset Voltage j DC Gain Linearity Error 0.00003% (typ) 0.00003% (typ) 2.7nV/√Hz (typ) ± 20V/µs (typ) 55MHz (typ) 140dB (typ) 10nA (typ) 0.1mV (typ) 0.000009% Features n n n n n Easily drives 600Ω loads Optimized for superior audio signal fidelity Output short circuit protection PSRR and CMRR exceed 120dB (typ) SOIC, DIP, TO-99 metal can packages Applications n n n n n n n n n Ultra high quality audio amplification High fidelity preamplifiers High fidelity multimedia State of the art phono pre amps High performance professional audio High fidelity equalization and crossover networks High performance line drivers High performance line receivers High fidelity active filters Key Specifications j Power Supply Voltage Range ± 2.5V to ± 17V Typical Application 201572K5 Passively Equalized RIAA Phono Preamplifier © 2006 National Semiconductor Corporation DS201572 www.national.com LM4562 Connection Diagrams 20157255 Order Number LM4562MA See NS Package Number — M08A Order Number LM4562NA See NS Package Number — N08E Metal Can 201572F3 Order Number LM4562HA See NS Package Number — H08C www.national.com 2 LM4562 Absolute Maximum Ratings (Notes 1, 2) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications.

all commercially available equipment. This makes distortion measurements just slightly more difficult than simply connecting a distortion meter to the amplifier’s inputs and outputs. The solution, however, is quite simple: an additional resistor. Adding this resistor extends the resolution of the distortion measurement equipment. The LM4562’s low residual distortion is an input referred internal error. As shown in Figure 1, adding the 10Ω resistor connected between the amplifier’s inverting and noninverting inputs changes the amplifier’s noise gain. The re- sult is that the error signal (distortion) is amplified by a factor of 101. Although the amplifier’s closed-loop gain is unaltered, the feedback available to correct distortion errors is reduced by 101, which means that measurement resolution increases by 101. To ensure minimum effects on distortion measurements, keep the value of R1 low as shown in Figure 1. This technique is verified by duplicating the measurements with high closed loop gain and/or making the measurements at high frequencies. Doing so produces distortion components that are within the measurement equipment’s capabilities. This datasheet’s THD+N and IMD values were generated using the above described circuit connected to an Audio Precision System Two Cascade. 201572K4 FIGURE 1. THD+N and IMD Distortion Test Circuit 23 www.national.com LM4562 Application Information NOISE MEASUREMENT CIRCUIT (Continued) The LM4562 is a high speed op amp with excellent phase margin and stability. Capacitive loads up to 100pF will cause little change in the phase characteristics of the amplifiers and are therefore allowable. Capacitive loads greater than 100pF must be isolated from the output. The most straightforward way to do this is to put a resistor in series with the output. This resistor will also prevent excess power dissipation if the output is accidentally shorted. 20157227 Complete shielding is required to prevent induced pick up from external sources. Always check with oscilloscope for power line noise.

Changed part number to LM4562. Updates based on inputs from design after KPC review. Edited 201572 55 (pkg drwg) and added the M08A mktg outline. Mjor edits on the EC table (by Heather). Input major text (Typical limits) edits. Some text edits. Edited Typical values on Zin. Added the Typ. Perf. Curves and some text edits. Added the 2 curves (Voltage/Current Noise Density vs Freq.) Replaced some of the curves. Added more curves. Initial WEB. Changed the Typical values on Instantaneous Short Circuit Current from +30/-38 into +53/-42 (per Robin S.), then re-released the D/S to the WEB. 0.10 0.15 0.20 0.25 0.30 0.35 0.40 0.45 5/25/05 10/5/05 11/01/05 02/02/06 05/31/06 06/07/06 08/02/06 08/07/06 0.50 0.55 0.56 0.57 08/08/06 08/10/06 08/16/06 08/22/06 31 www.national.com LM4562 Physical Dimensions inches (millimeters) unless otherwise noted Narrow SOIC Package Order Number LM4562MA NS Package Number M08A Dual-In-Line Package Order Number LM4562NA NS Package Number N08E www.national.com 32 LM4562 Dual High Performance, High Fidelity Audio Operational Amplifier Physical Dimensions inches (millimeters) unless otherwise noted (Continued) TO-99 Metal Can Package Order Number LM4562HA NS Package Number H08C National does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and National reserves the right at any time without notice to change said circuitry and specifications.
