Filter IC For Σ−∆ Modulation System DA Converter
TA2028F, TA2028P are an analog filter IC for Σ−∆ modulation system DA converter. Using the TA2028F, TA2028P 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. (+9V operation: BS tuner system)
· Noise distortion factor and S / N ratio are as follows (when operating at +5V single power supply): Noise distortion factor: −86dB (typ.) S / N: 100dB (typ.)
