National Semiconductor TP3040A

The TP3040 TP3040A filter is a monolithic circuit containing both transmit and receive filters specifically designed for PCM CODEC filtering applications in 8 kHz sampled systems The filter is manufactured using microCMOS technology and switched capacitor integrators are used to simulate classical LC ladder filters which exhibit low component sensitivity TRANSMIT FILTER STAGE The transmit filter is a fifth order elliptic low pass filter in series with a fourth order Chebyshev high pass filter It provides a flat response in the passband and rejection of signals below 200 Hz and above 3 4 kHz...
