PPMU Circuit

AD53508

FEATURES

Dual Measurement Channels

Precision Four-Quadrant-Per-Pin V/I Source

Programmable Current Force Ranges

؎204.8 ␮A and ؎2.048 mA

Five Current Measurement Ranges

204.8 nA to ؎2.048 mA

Output Voltage Range: –4 V to +9 V

Power Supplies: +15 V, +5 V, and –10 V

44-Lead Plastic J-Leaded Chip Carrier Package

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:

APPLICATIONS

Can Be Used with the AD53032 DCL to Extend Current

Force Range to 35 mA

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.

1. Accurately measuring low currents.

2. Can take parallel measurements by using one PMU per pin.
