BA6146

The BA6146 is a monolithic fluorescent-display tube driver IC. It can drive a 12-point VU-scale bar-level meter over an

input range of *20dB to 8dB. The IC has a low-offset rectifier amplifier, and does not require offset adjustment. It also

has built-in on / off muting function.

FApplications

Tape deck and amplifier VU meters.

FFeatures

1) Built-in low-offset rectifier amplifier. No offset adjust-

ment required.

2) Built-in power supply muting function.

3) The input rectifier amplifier can handle both AC and

DC input.

4) Wide operating power supply voltage range (oper-

ates from VCC = 7.5V).

5) Low current dissipation (4mA Typ.).
