STEVAL-CCA044V1: 160W x 2 @ 4Ω, 14 ~ 36V, Class D

Summary

The STEVAL-CCA044V1 demonstration board is designed for the TDA7498E high power dual BTL class-D audio amplifier. Thanks to its high efficiency, the device assembled in the PSSO36 (slug-down) package is capable of dissipating heat without a heatsink.Jumpers on the board allow the configuration of the amplifier to verify all the features as single-ended or differential input, fixed gain settings. Microswitches are also provided to enable the standby and mute functions.

Key Features

High output-power capability:
2 x 160 W / 4 Ω at 36 V, 1 KHz, THD = 10%
1 x 220 W / 4 Ω at 36 V, 1 KHz, THD = 10%
Wide-range, single supply operation (14 V- 36 V)
High efficiency (Efficiency= 85%)
Four selectable, fixed gain settings (23.6 dB, 29.6 dB,33.1 dB and 35.6 dB)
Differential inputs to minimize common-mode noise
Standby and mute features
Short-circuit and thermal overload protection
Externally synchronizable
