+3V, 8-Bit ADC with 1レA Power-Down
_______________General DescriptionThe 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.–P—O—W—E—R—D—O—W—N–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.

____________________Pin Description_______________Detailed Description
Converter OperationThe MAX152 uses a half-flash conversion technique
(see Functional Diagram) in which two 4-bit flash ADC
sections achieve an 8-bit result. Using 15 compara-
tors, the flash ADC compares the unknown input volt-
age to the reference ladder and provides the upper 4
data bits.
An internal digital-to-analog converter (DAC) uses the
4 most significant bits (MSBs) to generate the analog
result from the first flash conversion and a residue volt-
age that is the difference between the unknown input
and the DAC voltage. The residue is then compared
again with the flash comparators to obtain the lower 4
data bits (LSBs).
The MAX152 is characterized for operation between
+3.0V and +3.6V. Conversion times decrease as the
supply voltage increases. The supply current decreas-
es rapidly with decreasing supply voltage. (See
Typical Operating Characteristics.)
Power-Down ModeIn burst-mode or low sample-rate applications, the
MAX152 can be shut down between conversions,
reducing supply current to microamp levels (see
Typical Operating Characteristics). A logic low on the
PWRDNpin shuts the device down, reducing supply
current to typically 1µA when powered from a single 3V
supply. A logic high on PWRDNwakes up the
MAX152. A new conversion can be started within
900ns of the PWRDNpin being driven high (this
includes both the power-up delay and the track/hold
acquisition time). If power-down mode is not required,
connect PWRDNto VDD.
