Product Details
The MAX190 is a 12-bit analog to digital converter with
differential inputs, fast track/hold, high conversion speed and a high-speed serial or parallel interface.
The converter operates from a single +5V power supply with power down mode which reduces the supply to
current to 50µA.
Features
- 12-Bit Resolution, 1/2LSB Linearity
- Single +5V Operation
- Built-In Track/Hold
- Internal Reference with Adjustment Capability
- Low Power: 3mA Operating Mode 20µA Power-Down Mode
- Serial and 8-Bit Parallel µP Interface
