12-Bit ADC with Sequencer Simplifies Multiple-Input
Applications вЂ“ Design Note 274
Jeff Huehn
The LTC В®1851 is a new 12-bit, 1.25Msps ADC with
an 8-channel input multiplexer, a programmable gain
sample-and-hold and an internal reference. This Design
Note describes a novel feature of the LTC1851: a programmable sequencer that can automatically control
the input mux and sample-and-hold.
New ADC Automatically Converts Multiple Inputs
with Different Spans at Different Rates
LetвЂ™s imagine a hypothetical application with the following inputs: input A has a range of 0V to 4.096V
and needs to be sampled at 400ksps, input B needs
400ksps with a range of 0V to 2.048V, input C has a
range of В±2.048V around 2.5V and needs 200ksps,
input D needs 100ksps with a range of В±1.024V and
is truly differential with a common mode of 2V and
input E needs 100ksps with a range of 1V to 3.048V.
There are both single-ended and differential, unipolar
and bipolar inputs, two different spans and different
required sampling rates.
The solution is the LTC1851 sequencer, which allows
the user to program a repeating pattern of up to 16
independent mux addresses and conп¬Ѓgurations and …
