TDA7493 Overview
Description
The TDA7493 is a dual BTL class-D audio amplifier, specially designed for LCD TV, LCD monitors or small speakers on cradles with single-supply operation. The filterless operation allows the external component count to be reduced.
Key Features
- 3.0 W + 3.0 W of continuous output power with RL = 4 Ω, THD = 10%, VCC = 5 V (filterless)
- 2.8 W + 2.8 W of continuous output power with RL = 4 Ω, THD = 10%, VCC = 5 V (with filter)
- 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
