MC145480DW

The MC145480DW is one member of the MC145480 family which designed as the general purpose per channel PCM codecfilter with pin selectable MuLaw or ALaw companding, and is offered in 20pin DIP, SOG, and SSOP packages. MC145480DW has an advantage that noise injected via the power supplies is a commonmode signal that is cancelled when the inverted and noninverted signals are recombined.

Features of the MC145480DW are:(1)single 5 V power supply;(2)typical power dissipation of 23 mW, powerdown of 0.01 mW;(3)fullydifferential analog circuit design for lowest noise;(4)transmit bandpass and receive lowpass filters onchip;(5)active RC prefiltering and postfiltering;(6)mulaw and Alaw companding by pin selection;(7)onchip precision reference voltage (1.575 V);(8)pushpull 300 W power drivers with external gain adjust.

The absolute maximum ratings of the MC145480DW 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.
