3Msps/2Msps, 5V/3V, 2-Channel, True-  
Differential 12-Bit ADCs  
General Description  
Features  
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).  
3Msps Sampling Rate (+5V, MAX1332)  
2Msps Sampling Rate (+3V, MAX1333)  
Separate Logic Supply: +2.7V to +3.6V  
Two True-Differential Analog Input Channels  
Bipolar/Unipolar Selection Input  
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  
Only 38mW (typ) Power Consumption  
Only 2µA (max) Shutdown Current  
High-Speed, SPI-Compatible, 3-Wire Serial  
Interface  
power supply input (DV ) that allows direct interfacing  
DD  
2MHz Full-Linear Bandwidth  
to +2.7V to +3.6V digital logic. The fast conversion  
speed, low power dissipation, excellent AC perfor-  
mance, and DC accuracy ( 0.6 ꢀSB Iꢁꢀ) maꢂe the  
MAX1332/MAX1333 ideal for industrial process control,  
motor control, and base-station applications.  
71.4dB SINAD and -93dB THD at 525kHz Input  
Frequency  
No Pipeline Delays  
Space-Saving (3mm x 3mm), 16-Pin, TQFN  
The MAX1332/MAX1333 are available in a space-sav-  
ing (3mm x 3mm), 16-pin, TQFꢁ pacꢂage and operate  
over the extended (-40°C to +85°C) temperature range.
