At 100 W × 2 into 6 Ω, the output stage runs in Class D topology, which keeps efficiency above 80 % across most of the power band — the heatsink area needed is roughly half what a linear amp of the same output would require. ## Supply range and temperature grade — where this part fits on the board The 14 V to 39 V supply input covers common audio rails: a 24 V industrial supply, a 36 V brick for pro-audio gear, or a regulated 12 V boosted through a front-end converter. The wide margin means the same BOM position can serve multiple product variants without a supply redesign. ## Protection features and standby — what the integrated blocks save you On-chip short-circuit and thermal protection eliminate the need for external crowbar circuits or PTC fuses on each channel. The mute and standby pins let a microcontroller or DSP put the amplifier into a low-power idle state between audio events, dropping the quiescent draw to under 10 mA. Differential inputs reject ground-loop hum common in multi-box audio systems — the input common-mode range tracks the supply midpoint, so the amplifier does not require a separate analog ground reference.","metaTitle":"STMicroelectronics TDA7498TR Class D Amp, 100W x 2 @ 6Ω","metaDescription":"ST TDA7498TR Class D stereo amplifier, 100W per channel into 6Ω, 14-39V supply, industrial temp range, active production, RoHS3.
