This file is the TDA7493's user manual. It introduces the features of TDA7493, including 3.0 W + 3.0 W of continuous output power, single supply voltage range 3.0 V to 5.5 V, high efficiency (η = 83%), four selectable, fixed gain settings of 6 dB, 12 dB, 15.6 dB and 18 dB, differential inputs minimize common-mode noise, filterless operation, standby feature, short-circuit protection, thermal-overload protection, externally synchronizable
The TDA7493 is a dual Bridge-Tied Load (BTL) Class-D audio amplifier specifically designed for applications such as LCD TV and monitor speakers. It features high efficiency, single-supply voltage operation ranging from 3.0 V to 5.5 V, and four selectable fixed gain settings.
The device supports both filterless modulation and configurations with external LC filters. Key features include differential inputs to minimize common-mode noise, a standby feature for power saving, short-circuit protection, and thermal-overload protection. It is housed in an HTSSOP24 package with an exposed pad down design that eliminates the need for a separate heatsink.
| Output Power (Filterless) | 3.0 W + 3.0 W |
|---|---|
| Output Power (With Filter) | 2.8 W + 2.8 W |
| Supply Voltage Range | 3.0 V to 5.5 V |
| Efficiency | 83% |
| Package Type | HTSSOP24 with exposed pad down |
The device operates within a temperature range of 0 to 70°C.
No, thanks to its high efficiency and exposed-pad-down package, no separate heatsink is required.
The amplifier offers four selectable, fixed gain settings of 6 dB, 12 dB, 15.6 dB and 18 dB.
