... This eliminates the latency found in conven- tional converters and simplifies multiplexed applica- tions. Through a single pin, the LTC2401/LTC2402 can be configured for better than 110dB rejection at 50Hz or 60Hz 2%, or can be driven by an external oscillator for a user defined rejection frequency in the range 1Hz to 120Hz ...

... R as shown in Figure 2. The voltage drop across these parasitic resistors leads to systematic offset and full-scale errors. In order to eliminate the errors associated with these parasitic resistors, the LTC2401/LTC2402 include a full- scale set input (FS ( shown in Figure 3, the FS SET ...

... ADC sample rate (15,600Hz) are not present. For this application recommended the LTC2402 is placed in close proximity to the bridge sensor in order to reduce the noise injected into the ADC input. By performing three successive conversions (CH0-CH1-CH0), the drift and low frequency noise can be measured and compensated for digitally ...
