PRODUCT DESCRIPTION

tion voltage is programmable from 2 V to +7 V, covering the

large spectrum of logic devices while able to support the large

current specifications (48 mA) typically associated with line

drivers. To test I/O devices, the active load can be switched into

a high impedance state (Inhibit mode) electrically removing the

active load from the path through the Inhibit mode feature. The

active load leakage current in Inhibit is typically 20 nA.

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 I_OHPROGand I_OLPROGcurrents. The I_OH

and I_OLcurrents are determined by applying a corresponding

voltage (5 V = 50 mA) to the I_OHand I_OLpins. The voltage-

to-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 Inhibit input circuitry is implemented utilizing high speed

differential inputs with a common-mode voltage range of 7 volts

and a maximum differential voltage of 4 volts. This allows for

the direct interface to the precision of differential ECL timing or

the simplicity of switching the Active Load from a single ended

TTL or CMOS logic source. With switching speeds from IOH

or Io~ into Inhibit of less than 1.5 ns, the AD1315 can be

electrically removed from the signal path “on-the-fly.”

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-

The AD1315 is available in a 16-lead, hermetically sealed gull

wing package and is specified to operate over the ambient com-

mercial temperature range from 0°C to +70°C.
