TA2028F / P
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA2028F,TA2028P
Filter IC For - Modulation System DA Converter
TA2028F, TA2028P are an analog filter IC for - modulation system DA converter. Using the TA2028F, TA2028P in combination the TC9237BF, TC9237BN (the - 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.)

Application Circuit Example
(Cautions) * Quality of crystal oscillation waveform largely effects S / N ratio. Further, this is also true when system clock is input externally through the XI pin of pin(16). * Suppress glitch of input signals (LRCK, BCK, DATA) as could as possible. * The wiring between the TC9237BF, TC9237BN output and the analog filter amplifier input must be made the shortest * The capacitor between VDA and GNDA shall be connected as close to the pin as possible. * NC pin is used in the open state.
