DESCRIPTION
16-Bit 2-/4-Channel ΔΣ
ADC with Easy Drive Input
Current Cancellation
The LTC2488 is a 4-channel (2-channel differential), 16-
bit, No Latency ΔΣ ADC with 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 rail-to-
rail input signals to be directly digitized while maintaining
exceptional DC accuracy.
The LTC2488 includes an integrated oscillator. This device
can be congured to measure an external signal from
combinations of 4 analog input channels operating in single
ended or differential modes. It automatically rejects line
frequencies of 50Hz and 60Hz simultaneously.
The LTC2488 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 rst conversion after a new channel
selection is valid.
