DescripTion
The LTC2497 is a 16-channel (eight differential), 16-bit,
No Latency
DSTM ADC with Easy Drive technology and a
2-wire,I2Cinterface.Thepatentedsamplingschemeelimi-
nates 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 LTC2497 includes an integrated oscillator. This device
canbeconfiguredtomeasureanexternalsignalfromcom-
binations of 16 analog input channels operating in single-
ended or differential modes. It automatically rejects line
frequencies of 50Hz and 60Hz simultaneously.
The LTC2497 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. Access to the multiplexer output enables
optional external amplifiers to be shared between all
analog inputs and auto calibration continuously removes
their associated offset and drift.
