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. |
