Product Overview

The EVAL-SSM2377Z is an evaluation board for the SSM2377 filterless, Class-D audio amplifier. The SSM2377 is a fully integrated, high efficiency, Class-D audio amplifier. It is designed to maximize performance for mobile phone applications. The SSM2377 produces ultralow EMI emissions that significantly reduce the radiated emissions at the class-D outputs, particularly above 100MHz. The SSM2377 passes FCC class-B radiated emission testing with 50cm, unshielded speaker cable without any external filtering. The device also includes a gain select pin that allows the user to select a 6dB or a 12dB gain. This option improves gain matching between multiple SSM2377 devices within a single application as compared to using external resistors to set the gain. Input impedance is 80kΩ and is independent of the gain setting.
  • Filterless class-D amplifier with spread spectrum Σ-Δ modulation
  • 2.5W into 4Ω load and 1.4W into 8Ω load at 5V supply with <1% THD + N
  • It delivers 92% efficiency at 5V, 1.4W into 8Ω speaker
  • It has >100dB signal to noise ratio (SNR)
  • It provides high PSRR @ 217Hz of 80dB
  • It features ultra low EMI emissions mode
  • Gain select function of 6dB or 12dB
  • Fixed input impedance of 80kΩ
  • It has 100nA shutdown current
  • Short circuit and thermal protection with auto recovery
