10-Bit Plus Sign Serial I/O A/D Converters
with MUX, Sample/Hold and Reference
General Description
This series of CMOS 10-bit plus sign successive approxima-
tion A/D converters features versatile analog input multi-
plexers, sample/hold and a 2.5V band-gap reference. The
1, 2, 4 or 8-channel multiplexers can be software configured
for single-ended or differential mode of operation.
An input sample/hold is implemented by a capacitive refer-
ence ladder and sampled-data comparator. This allows the
analog input to vary during the A/D conversion cycle.
In the differential mode, valid outputs are obtained even
when the negative inputs are greater than the positive be-
cause of the 10-bit plus sign output data format.
The serial I/O is configured to comply with the NSC
MICROWIRE
TM
serial data exchange standard for easy in-
terface to the COPS
TM
and HPC
TM
families of controllers,
and can easily interface with standard shift registers and
microprocessors.
