ADC10662/ADC10664
10-Bit 360 ns A/D Converter with Input Multiplexer and
Sample/Hold
General Description
Using an innovative, patented multistep

nique, the 10-bit ADC10662 and ADC10664 are 2- and
4-input
CMOS
analog-to-digital
sub-microsecond conversion times yet dissipating a maxi-
mum of only 235 mW. The ADC10662 and ADC10664 per-
form 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.
In addition to standard static performance specifications
(Linearity, Full-Scale Error, etc.) dynamic performance (THD,
S/N) is guaranteed.
The analog input voltage to theADC10662 andADC10664 is
sampled and held by an internal sampling circuit. Input sig-
nals at frequencies from dc to over 250 kHz can therefore be
digitized accurately without the need for an external
sample-and-hold circuit.
The ADC10662 and ADC10664 include a “speed-up” pin.
Connecting an external resistor between this pin and ground
reduces the typical conversion time to as little as 360 ns.
For ease of interface to microprocessors, theADC10662 and
ADC10664 have been designed to appear as a memory lo-
cation or I/O port without the need for external interface
logic.
