Product Overview

DC1826A-A demonstrates the performance of the LTC2389-18 ADC in conjunction with the DC718C QuikEval II data collection board. The LTC2389-18 is a low noise, high speed 18bit successive approximation register ADC which operates from a single 5V supply. The LTC2389-18 supports pin configurable fully differential, pseudo-differential unipolar, and pseudo-differential bipolar analog input ranges, allowing it to interface with multiple signal chain formats without requiring additional level translation or signal conditioning. Fast 2.5Msps throughput with no cycle latency in the parallel interface modes makes the LTC2389-18 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The default reference is the LTC2389-18’s internal 4.096V reference. If an external reference is desired use the on board LTC6655-4.096 reference. LT6201 op amp is used to drive ADC.
  • Guaranteed 18bit no missing codes
  • 2.5Msps throughput rate with serial max clock in frequency of 100MHz
  • Internal reference buffer
  • No pipeline delay, No cycle latency
  • Parallel and serial I/O interface
  • Nap and sleep power down modes reduce power consumption
