Edge4707B Quad Channel Per-Pin Precision Measurement Unit TEST AND MEASUREMENT PRODUCTS Description The Edge4707B is a precision measurement unit designed for automatic 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 Edge4707B Features a PMU that can force or measure voltage over a 15V I/O range, and supports 4 current ranges: 2 µA, 200 µA, 20 µA, and 2 m A. Each channel of the Edge4707B Features an on-board window parator that provides two bits of information: DUT too high and DUT too low. There is also a monitor function which provides a real time analog signal proportional to either the measured voltage or current. The Edge4707B is designed to be a low power, low cost, small footprint solution to allow high pin count testers to support a PMU per pin. In addition, two independent switches per channel (for a central PMU force and sense) plus two wide voltage analog muxes per channel are included.
