Automotive, 3.1-W, mono, analog input Class-AB audio amplifier

The TPA6211A1-Q1 device is a 3.1W mono fully-differential amplifier designed to drive a speaker with at least 3Ω impedance while consuming only 20mm2 total printed-circuit board (PCB) area in most applications. The device operates from 2.5V to 5.5V, drawing only 4mA of quiescent supply current. The TPA6211A1-Q1 device is available in the space-saving 8-pin HVSSOP package.

The device includes features such as a –80dB supply voltage rejection from 20Hz to 2kHz, improved RF-rectification immunity, small PCB area, and a fast start-up with minimal pop makes the TPA6211A1-Q1 device an excellent choice for emergency call applications. Additionally, the device supports low-power needs in infotainment and cluster applications, such as cluster chimes or driver notification.
