Merkmale

KI-Übersetzung
  • Low-power, 3.5 and 4.5-digit ADC with integrated LCD driver, single 2.7V to 5.25V supply
  • Includes internal reference, high-accuracy on-chip oscillator, and triple LCD driver
  • Internal charge pump powers integrated input buffers for single-supply operation
  • ADC configurable for ±2V or ±200mV input range with conversion results output to LCD
  • No external precision integrating or autozero capacitors, crystal oscillator, charge pump, or other circuitry required for dual-slope ADC
  • On-chip buffers for differential signal and reference inputs enable direct interface to high-impedance signal sources
  • Continuous internal offset calibration with >100dB rejection of 50Hz and 60Hz line noise
  • MAX1493/MAX1495 perform enhanced offset calibration at power-up; MAX1495 also supports on-demand enhanced calibration
  • Data hold and peak hold functions, plus user-programmable low-battery monitoring
  • MAX1493/MAX1495 in 32-pin 7mm×7mm TQFP package; MAX1491 in 28-pin SSOP and 28-pin DIP packages
  • All devices operate over 0°C to +70°C commercial temperature range
  • High resolution: MAX1495 — 4.5-digit (±19,999 counts); MAX1493 — 4.5-digit (±19,999 counts); MAX1491 — 3.5-digit (±1999 counts)
  • Sigma-Delta ADC architecture — no integrating or autozero capacitors required, >100dB simultaneous rejection of 50Hz and 60Hz
  • Selectable input range: ±200mV or ±2V
  • Selectable voltage reference: internal 2.048V or external
  • Internal high-accuracy oscillator requires no external components
  • Automatic offset calibration
  • Low power: 980μA maximum operating current
  • Evaluation kit available (order MAX1494EVKIT)
