ADC10461/ADC10462/ADC10464

10-Bit 600 ns A/D Converter with Input Multiplexer and

Sample/Hold

General Description

NOTE: The ADC10461 and ADC10462 are obsolete. They

are described here for reference only.

Features

n Built-in sample-and-hold

n Single +5V supply

n No external clock required

n Speed adjust pin for faster conversions (ADC10462 and

ADC10464)

Using an innovative, patented multistep* conversion tech-

nique, these 10-bit CMOS analog-to-digital converters offer

sub-microsecond conversion times yet dissipate a maximum

of only 235 mW. These converters perform 10-bit conversion

in two lower-resolution “flashes”, yielding a fast A/D without

the cost, power consumption, and other problems associ-

ated with true flash approaches. Dynamic performance

(THD, S/N) is guaranteed.

Key Specifications

n Conversion Time

600 ns (typical)

800 kHz

n Sampling Rate

n Low Power Consumption

n Total Harmonic Distortion (50 kHz)

n No Missing Codes

235 mW (max)

−60 dB (max)

Over Temperature

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.

Applications

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.

n Digital signal processor front ends

n Instrumentation

n Disk drives

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.

n Mobile telecommunications
