Features

AI Translation
  • The MAX191 is a monolithic, CMOS, 12-bit analog-to-digital converter (ADC) featuring differential inputs, track/hold (T/H), internal voltage reference, internal or external clock, and parallel or serial μP interface.
  • The MAX191 has a 7.5μs conversion time, a 2μs acquisition time, and a guaranteed 100ksps sample rate.
  • The MAX191 operates from a single +5V supply or from dual ±5V supplies, allowing ground-referenced bipolar input signals.
  • The device features a logic power-down input, which reduces the 3mA VDD supply current to 50μA max, including the internal-reference current.
  • Decoupling capacitors are the only external components needed for the power supply and reference.
  • This ADC operates with either an external reference, or an internal reference that features an adjustment input for trimming system gain errors.
  • The MAX191 provides three interface modes: two 8-bit parallel modes, and a serial interface mode that is compatible with SPITM, QSPITM, and MICROWIRETM serial-interface standards.
  • 12-Bit Resolution, 1/2LSB Linearity
  • ±5V or ±5V Operation
  • Built-In Track/Hold
  • Internal Reference with Adjustment Capability
  • Low Power: 3mA Operating Mode, 20μA Power-Down Mode
  • 100ksps Tested Sampling Rate
  • Serial and 8-Bit Parallel μP Interface
  • 24-Pin Narrow DIP and Wide SO Packages
