SSM2301-MINI-EVALZ: 1.4W @ 8Ω, 2.5 ~ 5 Vin

Summary

The SSM2301 mini evaluation board features the SSM2301 filterless Class-D amplifier, designed to drive a BTL mono loudspeaker in portable audio applications. The SSM2301 mini evaluation board operates from a dc power supply that can provide 2.5 V to 5.5 V. The audio input source is amplified to drive 1.4 W into an 8 Ω loudspeaker at 5.0 V supply. The SSM2301 mini evaluation board accepts differential or single-ended input signals.

On the left of the SSM2301 mini evaluation board layout, there are three input audio signals: IN+, IN−, and GND (see Figure 6). The mini evaluation board takes audio signals by using IN+ and IN− to receive audio signals from common appliances, such as DVD players, personal computers, and TVs.
