B&K Precision Corporation, the suppliers of test and measurement products, has released model 570A analog and model 575A digital hand held IC testers, and optional AK57X functional IC test generating software.

The compact, hand held, battery powered testers from Unispan Instruments offer advanced functionality and ease of use.

The 2-line x 16 character dot matrix LCD shows the result of the test as a pass or fail, together with individual pin diagnostics, test made and possible equivalents. Both units contain extensive built-in test libraries.

The model 570A analog IC tester’s built-in test library includes all common analog ICs including op-amps, comparators, voltage regulators, voltage references, analog switches and multiplexes, opto-isolators and couplers and audio ICs.

The model 575A digital IC tester’s built-in test library includes a broad range of TTL, CMOS, memory, LSI, interface and other devices of up to 40 pins. Proven test software, advanced technology, make these testers ideal additions to any tool kit.

Model 570A analog IC tester:


The B+K Precision model 570A emulates passive circuitry around the device under test to ensure that a comprehensive test takes place. High integrity verification offers guaranteed levels of reliability in the results.

Conditional and unconditional loop testing modes ensure that intermittent and/or temperature related faults are detected.

The tester automatically senses the functionality of the device to be tested and displays a list of possible equivalents for replacement. Unmarked and house-coded ICs are easily identified and tested.

As part of the IC test, the specific IC number, the functional description of the device, and the status of faulty pins are scrolled through on the built-in display.

Good features of the model 570A include:

  • Auto identification mode
  • Conditional/Unconditional loop testing mode
  • Functional test unit emulates passive circuitry to implement a comprehensive test in a variety of configurations and gain settings
  • Displays diagnostic information down to individual component pins
  • Rugged, hand held, battery operated
  • Built-in membrane keypad, 2 x 16 dot matrix alphanumeric LCD, and high quality 16 pin ZIF socket
  • Mains adaptor available

Model 575A digital IC tester:

The B+K Precision model 575A is able to locate intermittent and temperature related faults by using its unconditional or conditional loop testing modes.

Unknown device identification is easily accomplished by selecting search from the menu, selecting the number of pins on the device and activating search mode.

The 575A will search its library and identify the device, displaying possible functional equivalents for replacement. As part of the IC test, the specific IC number, the functional description of the device, and the status of faulty pins are scrolled through on the built-in display.

Good features of the model 575A include:

  • Comprehensive device library covers most TTL, CMOS, memory and interface devices
  • 40 pin capability
  • Identifies unmarked and house-coded devices
  • Detects intermittent and temperature related faults
  • Displays diagnostic information for individual pins
  • Battery operated
  • Main adapter available

Model AK 57X optional IC test generating software:

The model AK57X is a PC based software package that permits users to add new devices to the library and create functional tests to suit specific applications.

The software requires a RS-232 or USB (adaptor required) connection to a PC and runs with Microsoft XP and a USB jack for licensing dongle.
