Overview

  • Single-Supply Operation
    • +4.5V to +5.5V (MAX1084)
    • +2.7V to +3.6V (MAX1085)
  • 10-Bit Resolution
  • 400ksps Sampling Rate (MAX1084)
  • Internal Track/Hold
  • Internal +2.5V Reference
  • Low Power: 2.5mA (400ksps)
  • SPI/QSPI/MICROWIRE 3-Wire Serial Interface
  • Pin-Compatible, High-Speed Upgrade to MAX1242/MAX1243
  • 8-Pin SO Package

The MAX1084/MAX1085 10-bit analog-to-digital converters (ADCs) combine a high-bandwidth track/hold, a serial interface with high conversion speed, an internal +2.5V reference, and low power consumption. The MAX1084 operates from a single +4.5V to +5.5V supply; the MAX1085 operates from a single +2.7V to +3.6V supply.

The 3-wire serial interface connects directly to SPI™/QSPI™/MICROWIRE™ devices without external logic. The devices use an external serial-interface clock to perform successive-approximation analog-to-digital conversions.

Low power combined with ease of use and small package size make these converters ideal for remote-sensor and data-acquisition applications, or for other circuits with demanding power consumption and space requirements. The MAX1084/MAX1085 are available in 8-pin SO packages.

These devices are pin-compatible, higher-speed versions of the MAX1242/MAX1243; for more information, refer to the respective data sheets.
