Application Notes

  • Choosing an Optocoupler for the ADS1202 Operating in Mode 1
    PDF, 116 Kb, File published: Feb 12, 2003
    The ADS1202 is a precision, 80-dB dynamic range, delta-sigma modulator operating from a single +5-V supply. The differential inputs are ideal for direct connections to transducers or low-level signals. With the appropriate digital filter and modulator rate, the device can be used to achieve 15-bit analog-to-digital conversion with no missing codes. This application report describes how to choose a
