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

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) PowerPAD™ 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.
