The LTC2492 is a 4-channel (2-channel differential), 24-bit, No Latency ??? ADC with Easy Drive technology. The patented sampling scheme eliminates dynamic input current errors and the shortcomings of on-chip buffering through automatic cancellation of differential input current. This allows large external source impedances and rail-to-rail input signals to be directly digitized while maintaining exceptional DC accuracy. The LTC2492 includes a high accuracy temperature sensor and an integrated oscillator. This device can be configured to measure an external signal (from combinations of 4 analog input channels operating in single-ended or differential modes) or its internal temperature sensor. It can be programmed to reject line frequencies of 50Hz, 60Hz, or simultaneous 50Hz/60Hz and configured to double its output rate. The integrated temperature sensor offers 1/30th?C resolution and 2?C absolute accuracy. The LTC2492 allows a wide common mode input range (0V to VCC), independent of the reference voltage. Any combination of single-ended or differential inputs can be selected and the first conversion after a new channel selection is valid.Applications Direct Sensor Digitizer Direct Temperature Measurement Instrumentation Industrial Process Control
