_______________General Description

The MAX152 high-speed, microprocessor (µP)-com-

patible, 8-bit analog-to-digital converter (ADC) uses a

half-flash technique to achieve a 1.8µs conversion

time, and digitizes at a rate of 400k samples per sec-

ond (ksps). It operates with single +3V or dual ±3V

supplies and accepts either unipolar or bipolar inputs.

–

—

–

pin reduces current consumption to

a typical value of 1µA. The part returns from power-

down and acquires an input signal in less than 900ns,

providing large reductions in supply current in applica-

tions with burst-mode input signals.

The MAX152 is DC and dynamically tested. Its µP inter-

face appears as a memory location or input/output port that

requires no external interface logic. The data outputs use

latched, three-state buffered circuitry for direct connection

to a µP data bus or system input port. The ADC's input/ref-

erence arrangement enables ratiometric operation. A fully-

assembled evaluation kit provides a proven PC board lay-

out to speed prototyping and design.
