Product Details

The MAX98500 evaluation kit (EV kit) is a fully assembled and tested circuit board that uses the MAX98500 boosted Class D amplifier to drive a mono bridge-tied-load (BTL) speaker in portable audio applications. Designed to operate from a 2.5V to 5.5V DC power supply, the EV kit delivers 2.2W into an 8Ω load. The EV kit accepts differential or single-ended input signals, features three selectable gain settings (6dB, 15.5dB, and 20dB), and provides separate speaker and boost shutdown inputs.
