The MAX1332/MAX1333 2-channel, serial-output,

12-bit, analog-to-digital converters (ADCs) feature two

true-differential analog inputs and offer outstanding noise

immunity and dynamic performance. Both devices easily

interface with SPI™/QSPI™/MICROWIRE™ and standard

digital signal processors (DSPs).

The MAX1332 operates from a single supply of +4.75V

to +5.25V with sampling rates up to 3Msps. The

MAX1333 operates from a single supply of +2.7V to

+3.6V with sampling rates up to 2Msps. These devices

feature a partial power-down mode and a full power-

down mode that reduce the supply current to 3.3mA

and 0.2µA, respectively. Also featured is a separate

power supply input (DV

to +2.7V to +3.6V digital logic. The fast conversion

speed, low power dissipation, excellent AC perfor-

mance, and DC accuracy (±0.6 LSB INL) make the

MAX1332/MAX1333 ideal for industrial process control,

motor control, and base-station applications.

The MAX1332/MAX1333 are available in a space-sav-

ing (3mm x 3mm), 16-pin, TQFN package and operate

over the extended (-40°C to +85°C) temperature range.
