PRODUCT DESCRIPTION
The AD1315 is a complete, high speed, current switching load designed for use in linear, digital or mixed signal test systems. By combining a high speed monolithic process with a unique surface mount package, this product attains superb electrical performance while preserving optimum packaging densities in an ultrasmall 16-lead, hermetically sealed gull wing package. Featuring current programmability of up to +50 mA, the AD1315 is designed to force the device under test to source or sink the programmed IOHPROG and IOLPROG currents. The IOH and IOL currents are determined by applying a corresponding voltage (5 V = 50 mA) to the IOH and IOL pins. The voltageto-current conversion is performed within the AD1315 thus allowing the current levels to be set by a standard voltage out digital-to-analog converter. The AD1315’s transition from IOH to IOL occurs when the output voltage of the device under test slews above or below the programmed threshold, or commutation voltage. The commuta-
tion voltage is programmable from 2 V to +7 V, covering the large spectrum of ……
