Product Summary

The max1897etp-t is a 12-bit analog-to-digital converter (ADC) operate from a single +5V supply and accept a 0V to 5V analog input. Both parts feature an 8.5µs successive-approximation ADC, a fast track/hold (1.5µs), an on-chip clock, and a high-speed 3-wire serial interface. The applications of the max1897etp-t are (1)Portable Data Logging; (2)Remote Digital Signal Processing; (3)solated Data Acquisition; (4)High-Accuracy Process Control.
