CONVERTERS WITH SERIAL INTERFACE
The ADS8328 is based on the same core and
includes a 2-to-1 input MUX with programmable
option of TAG bit output. Both the ADS8327 and
ADS8328 offer a high-speed, wide voltage serial
interface and are capable of chain mode operation
when multiple converters are used.
These converters are available in a 16-lead TSSOP
package and are fully specified for operation over the
industrial -40°C to +85°C temperature range.
