TA2009F

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA2009F,TA2009P Filter IC For Σ−∆ Modulation System DA Converter TA2009F/P 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.) Pin Connection (top view) Weight SSOP16−P−225−1.00A: 0.14g (typ.) DIP16−P−300−2.54A: 1.00g (typ.) 1 2002-10-30 Block Diagram TA2009F/P Description Of Pin Functions Pin No. Symbol I/O Function & Operation 1 RI + I R channel operational amplifier forward input terminal.
