ADC10061/ADC10062/ADC10064
10-Bit 600 ns A/D Converter with Input Multiplexer and
Sample/Hold
General Description
Using an innovative, patented multistep
*
conversion tech-
nique, the 10-bit ADC10061, ADC10062, and ADC10064
CMOS analog-to-digital converters offer sub-microsecond
conversion times yet dissipate a maximum of only 235 mW.
The ADC10061, ADC10062, and ADC10064 perform 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
ADC10061 is pin-compatible with the ADC1061 but much
faster, thus providing a convenient upgrade path for the
ADC1061.
The analog input voltage to the ADC10061, ADC10062, and
ADC10064 is sampled and held by an internal sampling cir-
cuit. 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.
