MC145076 Stereo Audio FIR Smoothing Filter

CMOS

The MC145076 is a combination re–clocking and smoothing filter designed especially for the MC145074 Stereo Audio DAC. Its versatility however, allows it to be used with any single bit–stream data converter to provide output reconstruction filtering, and to improve performance by restoring pulse shape integrity. The MC145076 provides a well controlled, filtered output that can be used directly, or with a current summing operational amplifier.
