100dB 20Bit Stereo ADC & DAC

General Description The AK4520 is a stereo CMOS A/D & D/A converter for middle-range MD/DAT, Surround System and musical instruments. Signal inputs and outputs are single-ended. The DAC outputs are analog filtered to remove out of band noise. External components are minimized. Features

Dual binary counter

DESCRIPTION The HEF4520B is a dual 4-bit internally synchronous binary counter. The counter has an active HIGH clock input (CP0) and an active LOW clock input (CP1), buffered outputs from all four bit positions (O0to O3) and an active HIGH overriding asynchronous master reset input (MR). The cou
