MAX1332 - (MAX1332 / MAX1333) True-Differential 12-Bit ADCs

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).

Features

  • 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.
  • Only 38mW (typ) Power Consumption.
  • Only 2µA (max) Shutdown Current.
  • High-Speed, SPI-Compatible, 3-Wire Serial Interface.
  • 2MHz Full-Linear Bandwidth.
  • 71.4dB SINAD and -93dB THD at 525kHz Input Frequency.
  • No Pipe.

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 powerdown mode that reduce the supply current to 3.3mA and 0.2µA, respectively.
