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 spacesaving 8-pin HVSSOP 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 applicati...
