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 LTC2487 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 4 analog input channels operating in singleended or differential modes) or its internal temperature sensor.
The integrated temperature sensor offers 1/2°C resolution and 2°C absolute accuracy.
The LTC2487 can be configured to provide a programmable gain from 1 to 256 in 8 steps.
