TB2173FTG
2-Source Stereo Headphone Amplifier
The TB2173FTG is a stereo headphone amplifier IC that can
accept two sources, developed for portable audio systems.
It is particularly ideal for digital portable audio systems having
built-in tuners.
Features
Accepts headphone amplifier inputs from two sources
Selectable headphone amplifier output: Output coupling or
OCL
Incorporates beep circuit
Incorporates power switch (controlled using port or command)
Supports power muting (controlled using port or command)
Features with single source only (tuner mode):
Electronic volume
Provides logic reset feature
Low-frequency boost (with AGC)
Two port expansion circuits
Operating supply voltage range: Ta = 25°C
VDD (opr) = 1.8 to 4.5 V
VCC1 (opr) = 1.8 to 4.5 V
VCC2 (opr) = 0.9 to 4.5 V
Note: Use the device with VCC1 greater than or equal to VCC2.
Handle the product with great care because its surge resistance is low.
Ensure that the product is mounted correctly.
Otherwise, the product or connected equipment may get damaged or degrade.
Weight: 0.05 g (typ.)
Product indication: B2173G
