RC7352
Parametric Measurement Unit
High resolution voltage measurement (
±
0.05%) and
accuracy: (
±
10mV max. offset) and 0.5% gain error
Internal current limit for ranges (A, B, & C)
Applications
ATE pin electronics measurements
Instrumentation, meters
Programmable voltage or current supply
Description
The RC7352 is a “Per Pin” Parametric Measurement Unit
(PMU) that can force voltage and measure current or force
current and measure voltage. The RC7352 forces voltages
from +15V to -5V when +V
S
is 20V and –V
S
is -10V, or
currents up to
±
40mA. All logic inputs for the RC7352 are
TTL compatible, while the open collector logic outputs are
TTL/CMOS compatible.
Setting the SI/V (Select I/V) pin low puts the RC7352 in
the force voltage and measure current mode. The resulting
output voltage at the DUT matches the input applied to the
Rev. 1.1.2
