_______________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
sAu–pP—pO—liWe—sE—Ra—nD—dO—aWc—Nc–eppitns
either unipolar or bipolar inputs.
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.
