鈥?Programmable voltage or current supply
Description
The RC7352 is a 鈥淧er Pin鈥?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 鈥揤
S
is -10V, or
currents up to
鹵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
