2-band Electronic Volume

For the availability of this product, please contact the sales office.

Description

48 pin QFP (Plastic)

The CXA2547Q is a 2-channel electronic volume

IC. A 34-bit serial data input controls the level and

characteristics of the output signal. It may be used

in car stereos and general audio systems.

Features

• Volume control

(from 0 dB to –80 dB, –∞ dB : Fine (1 dB-step)

Absolute Maximum Ratings (Ta=25 °C)

Coarse (8 dB-step)

• Supply voltage

VCC

• Balance

• Operating temperature Topr

• Storage temperature

• Allowable power dissipation

–40 to +85

°C

• Tone control

Tstg –65 to +150 °C

(2-band, 2 dB-step from –15 dB to +15 dB)

• Fader

350

2 dB-step to –20 dB, –25 dB, –35 dB, –45 dB, –60

dB, –∞ dB)

(Ta=85 °C)

• Input and gain selector (4 channels)

• Serial data control (DATA, CLK, CE)

• Single 8 V power supply

• Zero-cross detection circuit

(L/R independent operation for the volume block)

• Timer

Recommended Operating Conditions

Supply voltage 7 to 12

VCC

• Power-off mute

• Countermeasure to the noise of the portable

telephone

Structure

Bipolar silicon monolithic IC
