GENERAL DESCRIPTION
The AD53508 is a custom dual-channel parametric measure-
ment circuit for use in semiconductor automatic test equipment.
It contains programmable modes to force a pin voltage and
measure its current or to integrate and hold a current value.
Alternatively, a current can be forced and the compliance volt-
age measured.
The device provides a remote force/sense capability to ensure
accuracy at the tester pin. A guard output is available to drive
the shield of a force/sense pair.
Two input references per channel permit controlled switching to
different voltage or current levels. The forced voltage or current
levels can be switched back to the measurement system to read
back the analog levels for system calibration.
The circuit is powered by +15 V, +5 V and –10 V supplies and
dissipates 230 mW nominally.
Recommended Use of the PPMU with AD53032 DCL
The PPMU can be used with the AD53032 DCL to extend the
Current Force Range beyond 2 mA VCOM can be set to the
maximum spec allowance of 8 V, which would allow the maxi-
mum Current Force of IOL of 35 mA. The combination of the
PPMU and the DCL would have a few benefits including:
1. Accurately measuring low currents.
2. Can take parallel measurements by using one PMU per pin.
