ADC10662/ADC10664

10-Bit 360 ns A/D Converter with Input Multiplexer and

Sample/Hold

General Description

Features

n Built-in sample-and-hold

n Single +5V supply

Using an innovative, patented multistep conversion tech-

nique, the 10-bit ADC10662 and ADC10664 are 2- and

4-input CMOS analog-to-digital converters offering

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.

n 2- or 4-input multiplexer options

n No external clock required

Key Specifications

n Conversion time to 10 bits: 360 ns typical, 466 ns

max over temperature

n Sampling Rate: 1.5 MHz (min)

n Low power dissipation: 235 mW (max)

n Total harmonic distortion (50 kHz): −60 dB (max)

n No missing codes over temperature

The analog input voltage to the ADC10662 and ADC10664 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.

Applications

n Digital signal processor front ends

n Instrumentation

n Disk drives

n Mobile telecommunications

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, the ADC10662 and

ADC10664 have been designed to appear as a memory lo-

cation or I/O port without the need for external interface

logic.
