Description
LTC2470
Selectable 208sps/833sps 16-Bit,
Single-Ended, D∑ ADC with SPI Interface
Demonstration circuit 1628A features the LTC
®
2470, a
16-bit high performance Δ∑ analog-to-digital converter
(ADC) with an SPI interface. The input is unipolar with a range
of 0V to 1.25V. The modulator’s proprietary sampling tech
-
nique reduces the average input current to less than 50nA–
orders of magnitude lower than typical Δ∑ ADCs.
DC1628A is a member of Linear Technology‘s QuikEval™
f
amily of demonstration boards. It is designed to allow easy
evaluation of the LTC2470 and may be connected directly
to the target application’s analog signals while using the

DC590 USB Serial Controller board and supplied software
to measure performance. The exposed ground planes allow
proper grounding to prototype circuitry. After evaluating
with Linear Technology’s software, the digital signals can
be connected to the end application’s processor/controller
for development of the serial interface.
