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.

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.

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 to 10 bits

n Sampling Rate

n Low power dissipation

n Total harmonic distortion (50 kHz)

n No missing codes over temperature

600 ns typical

800 kHz

235 mW (max)

−60 dB (max)

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.

Applications

n Digital signal processor front ends

n Instrumentation

n Disk drives

n Mobile telecommunications

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.

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.
