ΣTM
analog-to-digital converter with patented Easy Drive
TM tech-
nology. The patented sampling scheme eliminates dynamic
input current errors and the shortcomings of on-chip buff-
ering 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 digi-
tized while maintaining exceptional DC accuracy.
The LTC2480 includes on-chip programmable gain, a
temperature sensor and an oscillator. The LTC2480 can be
configured to provide a programmable gain from 1 to 256
in 8 steps, measure an external signal or internal tempera-
ture sensor and reject line frequencies. 50Hz, 60Hz or
simultaneous 50Hz/60Hz line frequency rejection can be
selected as well as a 2x speed-up mode.
The LTC2480 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 LTC2480 includes an on-chip trimmed oscil-
lator eliminating the need for external crystals or oscilla-
tors. Absolute accuracy and low drift are automatically
maintained through continuous, transparent, offset and
full-scale calibration.
