LME49720 in Audio Op-Amps (TI/Burr-Brown) Family
The LME49720 series from Texas Instruments is a premier family of ultra-low distortion, low-noise, high-slew-rate operational amplifiers designed specifically for high-fidelity audio applications. These dual-channel bipolars offer a remarkable 0.00003% THD+N and a low noise density of 2.7nV/√Hz. Engineered for professional-grade audio circuitry, these parts provide superior signal integrity, high output drive capability of up to 26mA, and a wide supply voltage range, making them a standard choice for high-performance signal chains and precision instrumentation.
Variants in This Sub-Family
Variants within the LME49720 family primarily differ by package type and environmental rating. The LME49720NA is provided in a standard 8-pin PDIP for through-hole prototyping or vintage-style builds, while the LME49720MA is available in an SOIC-8 surface-mount package for high-density PCBs. Additionally, there are metal can TO-99 variants (LME49720HA) which offer superior heat dissipation and shielding properties for extreme performance or military-spec requirements. Performance specifications across these variants remain largely consistent.
