EDGE4717D

Edge4717D Quad Channel, Per Pin Precision Measurement Unit TEST AND MEASUREMENT PRODUCTS Description The Edge4717D is a precision measurement unit designed for automated test equipment and instrumentation. Manufactured in a wide voltage CMOS process, it is a monolithic solution for a quad channel per pin PMU. Each channel of the Edge4717D features a PMU that can force or measure voltage over a typical 15V I/O range, and supports 4 current ranges: ± 3.2 µA, ± 80 µA, ± 2 mA, ± 30 mA. The Edge4717D has an on-board window comparator per channel that provides two bits of information — DUT too high and DUT too low. There is also a monitor pin which provides a real time analog signal proportional to either the voltage or current measured at the DUT. The Edge4717D is designed to be a low power, low cost, small footprint solution to allow high pin count testers to support a PMU per pin. On-board voltage clamps, with over-current detection, provide protection to the DUT and 4717D. The Edge4717D also has a sample-and-hold feature available for capturing DUT current or voltage measurements. The Edge4717D is a design improvement to the Edge4717 that features: – Increased FV/MV range – Improved over-current detection circuit functionality – LVTTL comparator outputs (pull-up resistors no longer required) – Improved HiZ switching characteristics – Improved Force Voltage Linearity Features FV / MI Capability FI / MV Capability FV / MV Capability FI / MI Capability 4 Curre...
