Filter IC For Σ−∆ Modulation System DA Converter

TA2009F, TA2009P are an analog filter IC for Σ−∆ modulation system DA converter.
Using the TA2009F, TA2009P in combination the TC9237BF, TC9237BN (the Σ−∆ modulation system DA converter with a built−in digital filter), it is possible to construct a DA conversion system with less external parts.

FEATUREs
• Built−in CR for LPFs and output (differential) amplifiers for the left and right channel.
• Single power supply operation.
• Noise distortion factor and S / N ratio are as follows
   (when operating at +5V single power supply):
   Noise distortion factor: −93dB (typ.)
   S / N: 100dB (typ.)
