ADC1061  Product Folder

Using a modified half-flash conversion technique, the 10-bit ADC1061 CMOS analog-to-digital converter offers very fast conversion times yet dissipates a maximum of only 235 mW. The ADC1061 performs a 10-bit conversion in two lower-resolution "flashes", thus yielding a fast A/D without the cost, power dissipation, and other problems associated with true flash approaches.

The analog input voltage to the ADC1061 is tracked and held by an internal sampling circuit. Input signals at frequencies from DC to greater than 160 kHz can therefore be digitized accurately without the need for an external sample-and-hold circuit.

For ease of interface to microprocessors, the ADC1061 has been designed to appear as a memory location or I/O port without the need for external interface logic.
