ICL7107 DPM and DVM chip from Intersil

The Intersil ICL7106 and ICL7107 are high performance, low power, 31/2 digit A/D converters. Included are seven segment decoders, display drivers, a reference, and a clock.

The ICL7106 is designed to interface with a liquid crystal display (LCD) and includes a multiplexed backplane drive; the ICL7107 will directly drive an instrument size light emitting diode (LED) display.

Features
  • Guaranteed Zero Reading for 0V Input on All Scales
  • True Polarity at Zero for Precise Null Detection
  • 1pA Typical Input Current
  • True Differential Input and Reference, Direct Display Drive
  • LCD ICL7106, LED lCL7107
  • Low Power Dissipation - Typically Less Than 10mW
ICL7109 12-Bit A/D Converter with 3-State Binary Outputs

This is one of the first mixed CMOS IC, I used it after studying Intersil CMOS Hot Ideas Book. It is also the most widely used Display chip. Many Millions of Instruments are built using this chip both in Instrumentation and Industrial Automation.

The ICL7106 was most popular in Hand Held DMM's and Clamp Meters as it used to drive a LCD Display. ICL7109 was to interface with Digital Comparators and Microprocessors.

EVAL6235PD demonstration board

EVAL6235PD demonstration board

Fully integrated DMOS three-phase brushless DC motor driver. Used in conjunction with the EVALPRACTISPIN interface board and practiSPIN software, the board provides an evaluation platform to test the features of the L6235 device. In particular, the board provides a means to evaluate the power dissipation performance of the IC in the PowerSO package.
