Converter Operation
The 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 Mode
In 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
PWRDN
pin shuts the device down, reducing supply
current to typically 1μA when powered from a single 3V
supply. A logic high on
PWRDN
wakes up the
MAX152. A new conversion can be started within
900ns of the
PWRDN
pin being driven high (this
includes both the power-up delay and the track/hold
acquisition time). If power-down mode is not required,
connect
PWRDN
to V
