Frequently Asked Questions
What bandwidth does LME49713HA provide, and why does it matter for high-fidelity audio circuits?
LME49713HA features a 55 MHz bandwidth, which is well beyond the 20 kHz audio band and ensures flat frequency response with negligible phase distortion across the full audible spectrum. This wide bandwidth is critical for audiophile preamplifiers and headphone amplifiers where signal integrity is paramount.
How does the TO-99 metal can package of LME49713HA benefit sensitive audio designs?
The hermetic TO-99 metal can package provides a shielded enclosure that reduces electromagnetic interference pickup compared to plastic packages. This is particularly valuable in low-noise audio circuits with input signal levels below 1 mV, where external EMI can introduce audible hum or noise.
For high-end headphone amplifier designs, how does LME49713HA compare to LME49710?
LME49713HA is a current-feedback amplifier with 86 dB minimum CMRR and 6 µA maximum bias current, targeting applications requiring high slew rate and bandwidth. LME49710 is a voltage-feedback variant; the LME49713HA's current-feedback architecture offers faster transient response, making it preferred for driving 32-ohm to 600-ohm headphone loads.
