LM4935RLEVAL
| Audio Sub-System with Dual-Mode Stereo Headphone & Mono High Efficiency Loudspeaker Amplifiers and Multi-Purpose ADC | Full production
|
| $1000.00 each | 1 |
| The LM4935 is an integrated audio subsystem that supports both analog and digital audio functions. The LM4935 includes a high quality stereo DAC, a mono ADC, a multipurpose SAR ADC, a stereo headphone amplifier, which supports output cap-less (OCL) or AC-coupled modes of operation, a mono earpiece amplifier and a mono high efficiency loudspeaker amplifier. It is designed for demanding applications in mobile phones and other portable Devices.
This LM4935RLEVAL is an evaluation kit designed to ease the evaluation and effort during the development of a circuit using the LM4935RL.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
