Description

The LM4869 features differential stereo inputs, BTL (bridge-tied load) outputs, and four externally selectable fixed gains. Operating on a single 5V supply, the LM4869 delivers 1.2W and 1.9W (typ) of output power to an 8 and 4 BTL load (Note 1), respectively, with less than 1% THD+N. The LM4869's gain is selected using two digital inputs. The nominal gain values are 6dB, 10dB, 15.6dB, and 21.6dB.

The LM4869 is designed for notebook and other handheld portable applications. It delivers high quality output power from a surface-mount package and requires few external components.

Other features include an active-low micropower shutdown mode input and thermal shutdown protection.

Reliability Metrics

Part Number Process EFR Reject EFR Sample Size PPM LTA Rejects LTA Device Hours FITS MTTF (Hours)

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.
