ADC10461/ADC10462/ADC10464

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

Sample/Hold

General Description

Features

n Built-in sample-and-hold

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.

These converters perform 10-bit conversion in two lower-

resolution “flashes”, yielding a fast A/D without the cost,

power consumption, and other problems associated with

true flash approaches. Dynamic performance (THD, S/N) is

guaranteed. The ADC10461 is pin-compatible with the

ADC1061 but is much faster, providing a convenient up-

grade path for the ADC1061.

n Single +5V supply

n 1, 2, or 4-input multiplexer options

n No external clock required

n Speed adjust pin for faster conversions (ADC10462 and

ADC10464)

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.

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.

Applications

n Digital signal processor front ends

n Instrumentation

n Disk drives

n Mobile telecommunications

Note: *U.S. Patent Number 4918449

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.
