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.

FEATUREs
1) Built-in low-offset rectifier amplifier. No offset adjustment 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 (operates from VCC = 7.5V).
5) Low current dissipation (4mA Typ.).

APPLICATIONs
    Tape deck and amplifier VU meters.
