Linear Device Tester
(IST-6700)

• Tests Operational Amplifiers, Voltage Comparators, Voltage Regulators, Digital-to-Analog, Analog-to-Digital Converters and small to medium wattage power supplies

• Low cost, fully programmable tester conducts parameter measurement and parametric Go/ No Go tests

• Automatic Handler interface allows "bin sorting" based on the value of a selected performance parameter

• Plug-in family Test Module with unique Personality Program Module makes operation easy and lowers system cost

• Battery back-up RAM stores user test programs for "one-time setup" operation.

• Stand-alone or PC interface operation allows "one-button" testing

THE IST-7500 is a programmable parametric tester that provides parameter measurements or parametric Go/No Go tests for a wide variety of Operational Amplifiers, Voltage Comparators, Voltage Regulators, Digital-to-Analog and Analog-to-Digital Converters. The IST-7500 can be interfaced to an automatic handler for high speed production testing and is also equipped with a RS-232 port for PC interface. The system communicates to the user through the 2 x 40 LCD display and the keyboard during stand alone mode.

The IST 7500 achieves exceptional accuracy and sensitivity through the extensive use of software controlled self-calibration and a relay group. The 7500 used this relay group to connect the required test circuits, select the appropriate voltage / current sources and establish the needed measurement loops for all the tests performed. This will allow the tester to perform highly accurate, repeatable, and safe measurements with the current measurement down to the pico amp range. The IST 7500 is a "stand alone" instrument and does not require any additional software, hardware or special training.

The IST 7500 provides the following parameter tests for the indicated devices:
