DESCRIPTION
NOTE: The ADC10061 and ADC10062 are obsolete.
They are described here for reference only.
Using an innovative, patented multistep* conversion
technique, these CMOS analog-to-digital converters
offer sub-microsecond conversion times yet dissipate
a maximum of only 235 mW. These converters
perform 10-bit conversions in two lower-resolution
“flashes”, yielding a fast A/D without the cost, power
consumption, and other problems associated with
true flash approaches.
The analog input voltage is sampled and held by an
internal sampling circuit. Input signals at frequencies
from DC to over 200 kHz can, therefore, be digitized
accurately without the need for an external sample-
and-hold circuit.
The ADC10062 and ADC10064 include a “speed-up”
pin. Connecting an external resistor between this pin
and ground reduces the typical conversion time to as
little as 350 ns with only a small increase in linearity
error.
For ease of interface to microprocessors, the
ADC10061, ADC10062, and ADC10064 have been
designed to appear as a memory location or I/O port
without the need for external interface logic.
