The TS4604 is a stereo headset driver and analog audio line driver with integrated reference to ground. It operates from a single supply of 3V to 4.8V and comes in a space-saving TSSOP28 package with external gain setting resistors and dedicated shutdown control. The driver provides 100mW headset drive into a 16Ω load and has a high PSRR of 90dB on the headset drive. It also features internal undervoltage mute, pop-and-click reduction circuitry, thermal shutdown, and output short-circuit protection.
The TS4604 is a stereo ground-referenced output analog line driver and stereo headset driver designed to eliminate the need for output DC-blocking capacitors. It operates from a single supply voltage of 3 V to 4.8 V and is available in a space-saving TSSOP28 package with a 0.65 mm pitch.
The device features dedicated shutdown control for each function, internal undervoltage mute, and protection against pop-and-click, thermal shutdown, and output short circuits. It delivers up to 100 mW per channel into a 16 Ω load and includes 8 kV human body model ESD protection cells on all outputs.
