ADS1259EVM (Left) and ADS1259EVM-PDK (Right)
This user's guide describes the characteristics, operation, and use of the ADS1259EVM, both by itself and
as part of the ADS1259EVM-PDK. This evaluation model (EVM) is an evaluation board for two different
devices. First, it can be used to evaluate the
, a low-noise, 24-bit, single-channel, delta-sigma
(
ΔΣ
) analog-to-digital converter (ADC). The ADS1259 can be used either in standalone applications or
with the
. The PGA280 is a high-precision instrumentation amplifier with digitally-controllable gain
and signal integrity test capability. The combination of these two devices forms a high-resolution
measurement system able to digitize a wide range of signals.
This EVM allows performance evaluations of both the ADS1259 and the PGA280. The EVM also allows
for PGA280 control of the ADS1259 through the use of the external chip select modes. Complete circuit
descriptions, schematic diagrams, printed circuit board (PCB) layouts, and bill of material are included in
this document.
