1 Introduction
The PCI-6308 series of isolated analog output cards includes the
following three cards:
X
PCI-6308V: Isolated 8-CH voltage output card
X
PCI-6308A: Isolated 8-CH voltage and current output card
X
PCI-6304V: Isolated 4-CH voltage output card
The PCI-6308V is a high-performance, 12-bit analog output board
with PCI interface that provides 8 identical voltage output chan-
nels, with each channel capable of: (1) bipolar
±
10V voltage out-
puts; (2) unipolar 0 - +10V voltage output; and (3) unipolar 0 to
user defined voltage output.
The PCI-6308V adopts the AD7564BRSZ, a state-of-the-art and
fully monotonic digital to analog converter. The AD7564 is a cur-
rent output DA converter which requires external reference volt-
age provided by TI REF102. The REF102 is a precision 10V
voltage reference. The drift is laser-trimmed to 2.5ppm/°C max
over the industrial temperature range.
The PCI-6308A is the combination of the PCI-6308V and a 8-CH
current output daughter board EXP-8A. The EXP-8A daughter
board includes 8 precision voltage-to-current converters/transmit-
ters, which convert voltage output of PCI-6308V to a current
source output. The EXP-8A is piggybacked onto the PCI-6308V.
Therefore, the PCI-6308A provides both voltage and current out-
puts at the same time. That is, the change of current output has
the direct proportion comparing to the change of voltage output.
