ADC1061
10-Bit High-Speed μP-Compatible A/D Converter with
Track/Hold Function
General Description
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
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 theADC1061 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.
