High-Speed 12-Bit ADC with External Reference Input
DescriptionThe MX7672 is a 12-bit, high-speed, BiCMOS, analog-to-digital converter (ADC) that performs conversions in as little as 3μs while consuming only 110mW of power. The MX7672 is a plug-in replacement for AD7672.
The MX7672 requires an external -5V reference. A buffered reference input minimizes reference current requirements and allows a single reference to drive several ADCs. External reference specifications can be chosen to suit the accuracy of the application. The ADC clock can be driven from either a crystal or an external clock source, such as a microprocessor (µP) clock.
Average input range is pin-selectable for 0 to +5V, 0 to +10V, or ±5V, making the ADC ideal for data-acquisition and analog input/output cards. A high-speed digital interface (125ns data-access time) with three-state data outputs is compatible with most µPs.
