MAXIM MAX1082, MAX1083 Technical data
General Description
The MAX1082/MAX1083 10-bit analog-to-digital converters (ADCs) combine a 4-channel analog-input multiplexer,
high-bandwidth track/hold (T/H), and serial interface with
high conversion speed and low power consumption. The
MAX1082 operates from a single +4.5V to +5.5V supply;
the MAX1083 operates from a single +2.7V to +3.6V supply. Both devices’ analog inputs are software configurable
for unipolar/bipolar and single-ended/pseudo-differential
operation.
The 4-wire serial interface connects directly to SPI™/QSPI™
and MICROWIRE™ devices without external logic. A serial
strobe output allows direct connection to TMS320-family
digital signal processors. The MAX1082/ MAX1083 use an
external serial-interface clock to perform successiveapproximation analog-to-digital conversions. The devices
feature an internal +2.5V reference and a reference-buffer
amplifier with a ±1.5% voltage-adjustment range. An
external reference with a 1V to VDDrange may also be
used.
The MAX1082/MAX1083 provide a hard-wired SHDN pin
and four software-selectable power modes (normal operation, reduced power (REDP), fast power-down (FASTPD),
and full power-down (FULLPD)). These devices can be
programmed to shut down automatically at the end of a
conversion or to operate with reduced power. When using
the power-down modes, accessing the serial interface
automatically powers up the devices, and the quick turnon time allows them to be shut down between all conversions.
The MAX1082/MAX1083 are available in 16-pin TSSOP
packages.

Note 1: Tested at V

; COM = GND, unipolar single-ended input mode.
Note 2: Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range has
been calibrated.
Note 3: Offset nulled.
Note 4: Ground the “on” channel; sine wave is applied to all “off” channels.
Note 5: Conversion time is defined as the number of clock cycles multiplied by the clock period; clock has 50% duty cycle.
Note 6: The common-mode range for the analog inputs (CH3–CH0 and COM) is from GND to V
DD1
.
Note 7: External load should not change during conversion for specified accuracy.
Note 8: ADC performance is limited by the converter’s noise floor, typically 300µVp-p. An external reference below 2.5V
compromises the performance of the ADC.
Note 9: Electrical characteristics are guaranteed from V

. For operations beyond
this range, see Typical Operating Characteristics. For guaranteed specifications beyond the limits, contact the factory.
