Buffered ADC Family Eliminates
Signal Conditioning Complexity
Joe Sousa, Andrew Thomas, Clement Wagner, Mark Thoren
Engineers often assume that analog-to-digital converter
inputs are high impedance. Direct-sampling SAR ADC
inputs will often be high impedance when not converting, but will draw вЂњspikesвЂќ of current at the beginning
of sample acquisition. On average, this behavior can be
modeled as a crude nonlinear resistance that is inversely
proportional to the sample capacitor size and sample rate,
but instantaneously the signal chain must be able to settle
completely in response to this abuse before acquisition
ends and a conversion begins. Coupling a signal chain to an ADC is an art form, often requiring a combination of theory
and experimentation. By contrast, the LTC2358 family of
multi-channel, buffered high voltage SAR ADCs offers
truly high impedance inputs that simplify or eliminate the
need for signal conditioning in many cases. When signal
conditioning is required, it can be directly connected to
the LTC2358 inputs without regard to its ability to drive
a switched capacitor. The following circuits show some
applications that take advantage of the properties of the
LTC2358 inputs. …
