3Msps/2Msps, 5V/3V, 2-Channel, True-
Differential 12-Bit ADCs
General Description
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 (DVDD) that allows direct interfacing
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.
