Product Overview

The LTC2448IUHF#PBF is a 16-channel high speed 24-bit no latency Analog-to-digital Converter (ADC) uses a proprietary delta-sigma™ architecture enabling variable speed/resolution. Through a simple 4-wire serial interface, ten speed/resolution combinations 6.9Hz/280nVRMS to 3.5kHz/25µVRMS can be selected with no latency between conversion results or shift in DC accuracy. Additionally, a 2X speed mode can be selected enabling output rates up to 7kHz with one cycle latency. Any combination of single-ended or differential inputs can be selected with a common mode input range from ground to VCC, independent of VREF. While operating in the 1X speed mode the first conversion following a new speed, resolution or channel selection is valid. At the conclusion of each conversion, the converter is internally reset eliminating any memory effects between successive conversions and assuring stability of the high order delta-sigma modulator.
  • Selectable speed/resolution
  • Guaranteed modulator stability and lock-up immunity for any input and reference conditions
  • Differential input and differential reference with GND to VCC common mode range
  • No latency mode, each conversion is accurate even after a new channel is selected
  • Internal oscillator - no external components
