The LTC2494 is a 16-channel (8-differential), 16-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 LTC2494 includes programmable gain, a high accuracy temperature sensor and an integrated oscillator. This device can be configured to measure an external signal (from combinations of 16 analog input channels operating in single-ended or differential modes) or its internal temperature sensor. The integrated temperature sensor offers 1/2?C resolution and 2?C absolute accuracy. The LTC2494 can be configured to provide a programmable gain from 1 to 256 in 8 steps. The LTC2494 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 is selected, is valid.Applications Direct Sensor Digitizer Direct Temperature Measurement Instrumentation Industrial Process Control
