Detailed Description

LTC2484: 24-Bit Delta Sigma ADC with Easy Drive Input Current Cancellation.

The LTC2484 combines a 24-bit no latency delta-sigma analog-to-digital
converter with patented 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 input signals with rail-to-rail
input range to be directly digitized while maintaining exceptional DC accuracy.

The LTC2484 includes an on-chip oscillator. The LTC2484 can be configured to
reject line frequencies. 50Hz, 60Hz or simultaneous 50Hz/60Hz line frequency
rejection can be selected as well as a 2x speed-up mode.

The LTC2484 allows a wide common mode input range (0V to VCC) independent of the
reference voltage. The reference can be as low as 100mV or can be tied directly
to VCC. The LTC2484 includes an on-chip trimmed oscillator, eliminating the need
for external crystals or oscillators. Absolute accuracy and low drift are
automatically maintained through continuous, transparent, offset and full-scale
calibration.
