LTC2488 Series

The LTC2488 is a 4-channel (2-channel differential), 16-bit, No Latency ΔΣ™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 LTC2488 includes 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. It automatically rejects line frequencies of 50Hz and 60Hz simultaneously.The LTC2488 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.ApplicationsDirect Sensor DigitizerDirect Temperature MeasurementInstrumentationIndustrial Process Control
