Description
A 16.6MHz, 14-bit, bidirectional, parallel interface provides the conversion results and accepts digital configuration inputs.
These devices operate from a +4.75V to +5.25V analog supply and a separate +2.7V to +5.25V digital supply, and consume less than 50mA total supply current.
These devices come in a 48-pin TQFP package and operate over the extended -40°C to +85°C temperature range.
