It integrates differential inputs, mute, standby, and short-circuit plus thermal protection. The wide supply range of 14V to 36V gives flexibility for both consumer and pro-audio rails. ## 220W mono or 160W stereo — what drives the BOM decision The 220W x 1 @ 3Ω mono rating is the headline number for subwoofer or single-channel PA designs. The 160W x 2 @ 4Ω stereo rating matters when driving a pair of 4Ω bookshelf speakers. The real BOM constraint is the power supply: 36V rail at roughly 8A peak for the mono configuration, or a 24V rail at around 6A for stereo. The Class D efficiency (typically >85%) keeps the heatsink small — a slotted aluminium extrusion roughly 100mm x 50mm x 20mm is usually enough for stereo at moderate listening levels. The TDA7498MVTR sibling tops out at 100W mono, so this part is the higher-power pick when the load demands it.","metaTitle":"STMicroelectronics TDA7498ETR Class D Audio Amp","metaDescription":"TDA7498ETR Class D audio amplifier IC from STMicroelectronics. 220W mono or 160W stereo output.
