ADC10061/ADC10062/ADC10064
10-Bit 600 ns A/D Converter with Input Multiplexer and
Sample/Hold
General Description
NOTE: The ADC10061 and ADC10062 are obsolete. They
are described here for reference only.
Using an innovative, patented multistep* conversion tech-
nique, 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 associ-
ated 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 exter-
nal interface logic.
