16-Bit Linear CODEC Interface
For data acquisition systems, designers may opt for a 16-
For higher precision transmissions, a 16-bit linear CODEC
is used, however, data is not compressed in this mode of
transmission. The Z89321 provides accommodation for
bit serial A/D. A block diagram of the Z89321 with the
AD1876 16-bit 100 Kbps sampling ADC is shown in Figure
