The LM4562 chip's ultra-low distortion, low noise, high slew rate op amp series, high performance, high fidelity application optimization and fully specified part. Combined with the country's most advanced circuit design and advanced cutting-edge process technology, the LM4562 op amplifier provides excellent audio performance and superior audio signal amplification. The LM4562 chip combines a very low voltage-noise density (2.7nV/) √ ^Hz) with a very low THD + N (0.00003%), easily meeting the most demanding audio applications. To ensure that the most challenging loads are uncompromising drivers, the LM4562 chip features a high slew rate of ±20V/μs and an output current capability of ±26 milliamps. In addition, the dynamic range is maximized, driving the output stage when driving a 600Ω load within 1V and 1.4V of either supply voltage over a 2kΩ load range.
The LM4562 chip's excellent CMRR (120 dB), (PSRR120 dB) and V OS (0.1mV) amplifiers provide excellent operational amplifier DC performance.
The LM4562 chip has a wide supply voltage range of ± 2.5V to ± 17V. The input circuitry of the LM4562 chip maintains excellent common-mode and supply rejection over this supply voltage range, as well as maintaining its low input bias current. The LM4562 chip is unit gain stable. This op-amp achieves excellent AC performance with high values of up to 100pF for complex loads while driving.
The LM4562 chip is an 8-pin narrow-body SOIC, an 8-pin plastic DIP, and an 8-lead metal can TO-99. Each package presentation board.
