The AD5520 is a single-channel, per-pin parametric measurement unit (PPMU) for use in semiconductor automatic test equipment. The part is also suited for use as a source measurement unit for instrumentation.
The AD5520 is a single‑channel, per‑pin parametric measurement unit (PPMU) intended for semiconductor automatic test equipment and instrumentation. It can force a pin voltage and measure the resulting current, or force a current and measure the voltage, with a force‑sense capability for high accuracy.
Key features include a +11 V force voltage range, four programmable force/measure current ranges (+4 pA, +40 pA, +400 pA, +4 mA), on‑board force amplifier, guard driver, and a 64‑lead LQFP package. The device provides low‑offset, low‑drift amplifiers, high CMRR, and extensive protection features such as clamp circuitry and ESD protection.
