DESCRIPTION
24-Bit
Σ ADC with
Easy Drive Input Current Cancellation
The LTC
2484 combines a 24-bit No Latency
Σanalog-
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 temperature sensor and
oscillator. The LTC2484 can be congured to measure an
external signal or internal temperature sensor and reject
line frequencies. 50Hz, 60Hz or simultaneous 50Hz/60Hz
line frequency rejection can be selected as well as a 2
×
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 oscil-
lator, eliminating the need for external crystals or oscil-
lators. Absolute accuracy and low drift are automatically
maintained through continuous, transparent, offset and
full-scale calibration.
