MC145483DTR2

The MC145483DTR2 is desigend as one kind of 13bit linear PCM CodecFilter with 2s complement data format, and is offered in 20pin SOG and SSOP packages. Also MC145483DTR2 is designed to operate in both synchronous and asynchronous applications and contains an onchip precision reference voltage. With the help of an input operational amplifier whose output is the input to the encoder section, MC145483DTR2 could processing of an analog signal that is twice the amplitude allowed by a singleended design, which reduces the significance of noise to both the inverted and noninverted signal paths.

Features of the MC145483DTR2 are:(1)13bit linear ADC/DAC conversions with 2s complement data format;(2)single 3 V power supply;(3)typical power dissipation of 8 mW, powerdown of 0.01 mW;(4)fullydifferential analog circuit design for lowest noise;(5)transmit bandpass and rreceive lowpass filters onchip;(6)transmit highpass filter may be bypassed by pin selection;(7)active RC Prefiltering and postfiltering;(8)pushpull 300 W power drivers with external gain adjust;(9)3terminal input op Amp can be used, or a 2channel input multiplexer.

The absolute maximum ratings of the MC145483DTR2 can be summarized as:(1)DC supply voltage:-0.5 to 6 V;(2)voltage on any analog input or output pin:Vss-0.3 to VDD+0.3 V;(3)voltage on any digital input or output pin:Vss-0.3 to VDD+0.3 V;(4)operating temperature range:-40 to + 85 °C;(5)storage temperature range:-85 to +150 °C.
