TDA7316 - FOUR BANDSDIGITAL CONTROLLED GRAPHIC EQUALIZER

Description

The TDA7316 is a monolithic, digitally controlled graphic equalizer realized in BiCMOS mixed technology.

tenuated down to -17.625dB in 0.375dB step.

Features

• of each band pass filter are reported: fo = center frequency Gv = gain/loss at the center frequency fo Gv = 20log(Av) Q= fo f2.
• f1 where f2, f1 = 3dB Bandwidth limits. Av = (R2 ⋅ C2 ) + (R2 ⋅ C1 ) + (R1 ⋅ C1 ) (R2 ⋅ C1 ) + (R2 ⋅ C2 ) Q= fo = √  (R1 ⋅ C1 ⋅ R2 ⋅ C2 ) (R2 ⋅C1 ) + (R2 ⋅ C2 ) 1 2π ⋅  √ (R1 ⋅ R2 ⋅ C1 ⋅ C2) If C1 is fixed, then: C2 = R2 = Q2 Av.
