Features

General Description

TD9772A is an audio amplifier of Class‐AB type. It ◆ Vin: 2.5V to 5.5V

offers both excellent sound quality of

THD+N<0.03% , and input/output flexibilities.

TD9772A features three different output

configurations and four different input channels,

both selectable by external pins. Outputs can be

BTL,SE, or straight‐through. There are four input

channels making it convenient for the multigadgets

modern age. On‐chip DC volume control features

64 non‐linear digital steps from –84dB to 24dB for

better responsive to human ears While output

power can be as high as 2.6W, the maximum

output voltage can be adjusted by an external bias

so that output power can be limited. Output pin

short protection and over temperature shutdown

modes are to ensure good system integrity.

Internal soft switching designs are to minimize click

and pop noises during power up/down, mute, and

channel switching instances.

◆ Max Output Power (4‐ohm speaker): 2.6W

‐ With 64 Steps Volume Control

‐ Adjustable max Output Power Limits

◆ 4 selectable Inputs

◆ Supports 3 Output configurations: BTL, SE,

and Straight through.

‐ Maximum BTL gain: 24dB

‐ Maximum SE gain: 18dB

◆ Quiescent Current: <10mA

◆ Under Voltage Lockout at Vin <2V

◆ Short Circuit Protection

◆ Over Temperature Protection

◆ No Click and Pop noise: <10mW for BTL
