Overview
The TPA6211TDGNRQ1 is a 3.1W mono fully-differential audio power amplifier designed by Texas Instruments. This device is specifically tailored for automotive applications, meeting the AEC-Q100 qualification standards. It operates within a temperature range of –40°C to 105°C and features a compact 8-pin HVSSOP package, making it ideal for space-constrained designs. The amplifier is capable of driving speakers with at least 3Ω impedance while consuming a minimal quiescent supply current of 4mA at 5V. Its fast startup with minimal pop and low shutdown current of 0.01µA make it suitable for various automotive audio and notification systems.
