DESCRIPTION
24-Bit 2-/4-Channel
ΔΣ
ADC with Easy Drive Input
Current Cancellation
The LTC2492 is a 4-channel (2-channel differential),
24-bit, No Latency Δ∑ 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 LTC2492 includes a high accuracy temperature sensor
and 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 dif-
ferential modes) or its internal temperature sensor. It can
be programmed to reject line frequencies of 50Hz, 60Hz,
or simultaneous 50Hz/60Hz and congured to double
its output rate. The integrated temperature sensor offers
1/30th°C resolution and 2°C absolute accuracy.
The LTC2492 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.
