Features

AI Translation
  • The MAX146/MAX147 12-bit data-acquisition systems combine an 8-channel multiplexer, high-bandwidth track/hold, and serial interface with high conversion speed and low power consumption.
  • The MAX146 operates from a single +2.7V to +3.6V supply; the MAX147 operates from a single +2.7V to +5.25V supply.
  • Both devices’ analog inputs are software configurable for unipolar/bipolar and single-ended/differential operation.
  • The 4-wire serial interface connects directly to SPI/QSPI and MICROWIRE devices without external logic.
  • A serial strobe output allows direct connection to TMS320-family digital signal processors.
  • The MAX146/MAX147 use either the internal clock or an external serial-interface clock to perform successive-approximation analog-to-digital conversions.
  • The MAX146 has an internal 2.5V reference, while the MAX147 requires an external reference.
  • Both parts have a reference-buffer amplifier with a ±1.5% voltage-adjustment range.
  • These devices provide a hard-wired SHDN pin and a software-selectable power-down, and can be programmed to automatically shut down at the end of a conversion.
  • Accessing the serial interface automatically powers up the MAX146/MAX147, and the quick turn-on time allows them to be shut down between all conversions.
  • This technique can cut supply current to under 60μA at reduced sampling rates.
  • The MAX146/MAX147 are available in 20-pin DIP and SSOP packages.
  • 8-Channel Single-Ended or 4-Channel Differential Inputs
  • Single-Supply Operation +2.7V to +3.6V (MAX146), +2.7V to +5.25V (MAX147)
  • Internal 2.5V Reference (MAX146)
  • Low Power 1.2mA (133ksps, 3V supply), 54μA (1ksps, 3V supply), 1μA (power-down mode)
  • SPI/QSPI/MICROWIRE/TMS320-Compatible 4-Wire Serial Interface
  • Software-Configurable Unipolar or Bipolar Inputs
  • 20-Pin DIP/SSOP Packages
