3 Description

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

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