TC9482N

The TC9482N are six-channel electronic volume control ICs developed for Hi-Fi audio equipment. Since all six channels can be individually controlled, the devices are optimum for audio equipment with multiple outputs.

The features of TC9482N can be summarized as (1)sound volume can be controlled in 97 steps from to -95 dB or up to an infinite level in 1dB increments; (2)incorporating six channels of volume control circuits, the device allows independent volume control; (3)can operate with a single or dual power supplies; (4)can control up to 4 chips on the same bus by using chip select input.; (5)built-in interface for 5-V microcomputers; (6)thanks to its polysilicon resistor, the device allows you to configure a low-distortion, high-performance volume control system; (7)two packages supported: 28-pin shrink DIP and 28-pin flat package.

The absolute maximum ratings of TC9482N are (1)power supply voltage VDD: -0.3~36V; (2)GND block input voltage VIN: -0.3~VDD+0.3V; (3)power dissipation PD: 300mW; (4)operating temperature Topr: -40~85°C; (5)storage temperature Tstg: - 65~150°C.
