1 / 33 page Rev 2 July 2005 1/33 33 TS4975 Stereo Headphone Drive Amplifier with Digital Volume Control via I2C Bus ■ Operating from V CC = 2.5V to 5.5V ■ I²C bus control interface ■ 40mW output power @ Vcc=3.3V, THD=1%, F=1kHz, with 16 Ω load ■ Ultra-low consumption in stdby mode: 0.6 µA ■ Digital volume control range from 18dB to -34dB ■ 14-step digital volume control ■ 9 different output mode selections ■ Pop & click noise reduction circuitry ■ Flip-chip package 12 x 300µm bumps (lead- free) Description The TS4975 is a stereo audio headphone driver capable of delivering up to 102mW per channel of continuous average power into a 16 Ω single- ended load with 1% THD+N from a 5V power supply. The overall gain of these headphone drivers is controlled digitally by volume control registers programmed via the I²C interface, minimizing the number of external components needed. This device can also easily be driven by an MCU to select the output modes, through the I²C bus interface. A phantom ground configuration allows one to avoid using bulky capacitors on the outputs of the headphone amplifiers. The TS4975 is packaged into a 1.8mm X 2.3mm Flip Chip package, ideally suited for space- conscious portable applications. It has also an internal thermal shutdown protection mechanism. Applications ■ Mobile phones (cellular / cordless) ■ PDAs ■ Laptop/notebook computers ■ Portable audio devices Order Codes TS4975EIJT - Flip Chip OUT1 IN1 BYPASS PHG1 VCC SCL PHG2 GND SDA OUT2 IN2 ADD OUT1 IN1 BYPASS PHG1 VCC SCL PHG2 GND SDA OUT2 IN2 ADD Pin Out (top view) Part Number Temperature Range Package Packaging Marking TS4975EIJT -40, +85°C Flip-chip Tape & Reel A75 www.st.com |
