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.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.

Note 2: Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications

and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics
may degrade when the device is not operated under the listed test conditions.

Note 3: Amplifier output connected to GND, any number of amplifiers within a package.

Note 4: Human body model, 100pF discharged through a 1.5kΩ resistor.

Note 5: Machine Model ESD test is covered by specification EIAJ IC-121-1981. A 200pF cap is charged to the specified voltage and then discharged directly into

the IC with no external series resistor (resistance of discharge path must be under 50Ω).

Note 6: Typical specifications are specified at +25ºC and represent the most likely parametric norm.

Note 7: Tested limits are guaranteed to National's AOQL (Average Outgoing Quality Level).

Note 8: PSRR is measured as follows: VOS is measured at two supply voltages, ±5V and ±15V. PSRR = | 20log(ΔVOS/ΔVS) |.
