ADC10461/ADC10462/ADC10464
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 ADC10461, ADC10462, and ADC10464
CMOS analog-to-digital converters offer sub-microsecond
conversion times yet dissipate a maximum of only 235 mW.
The ADC10461, ADC10462, and ADC10464 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. Dy-
namic
performance
(THD,
S/N)
is
guaranteed.
The
ADC10461 is pin-compatible with the ADC1061 but much
faster, thus providing a convenient upgrade path for the
ADC1061.
The analog input voltage to the ADC10461, ADC10462, and
ADC10464 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 ADC10462 and ADC10464 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 ADC10461,
ADC10462, and ADC10464 have been designed to appear
as a memory location or I/O port without the need for exter-
nal interface logic.
