ICL 7106 Evaluation Kit

\\ ===== Overview ===== In the late 1970's an evaluation kit for the Intersil all in one Analog to Digital (ADC) chips with built in display drivers, ICL 7106 (LCD) and ICL 7107 (LED), was produced. These very successful chips are still produced today and are the engine of many digital multimeters. Although the boards are labeled "Intersil ICL7106 Evaluation Kit" ((the 7106 boards were also labeled "LEI MV3" and "Intersil 7106 LCD DPM")), I'm not actually sure whether they were manufactured by Intersil.

An assembled ICL 7106 Evaluation Kit.

===== Hardware description ===== There is a complete application note detailing these evaluation kits {{https://www.renesas.com/sg/en/document/apn/an023-low-cost-digital-panel-meter-designs-and-complete-instructions-lcd-and-led-kits?language=en|AN023 Low Cost Digital Panel Meter Designs and Complete Instructions for LCD and LED Kits}}{{electronic:equipment:icl7106:idt_an023_apn_19990330.pdf|.}} Apparently there were other versions of this kit, eg this EEP (Energy Electronic Products) one [[https://i.ebayimg.com/images/g/v6UAAOSwbn1eKJlJ/s-l1600.jpg]], and projects built around the board, eg [[https://www.industrial-electronics.com/c-e_magazine_exp_hndbk_1984_lidth.html|‘LIDITH' -- A 3½-Digit Digital Thermometer]]. ===== Examples ===== {{:electronic:equipment:icl7106:p1276740a.jpg?800|ICL 7106 Evaluation Kit PCB front}} {{:electronic:equipment:icl7106:p1276744a.jpg?800|ICL 7106 Evaluation Kit PCB back}} {{:electronic:equipment:icl7106:p1276749a.jpg?800|ICL 7106 Evaluation Kit PCB components}} {{:electronic:equipment:icl7106:p1276733a.jpg?800|ICL 7106 Evaluation Kit Assembled front}} {{:electronic:equipment:icl7106:p1276734a.jpg?800|ICL 7106 Evaluation Kit Assembled front}} ====== References and Additional Resources ====== * {{https://www.renesas.com/sg/en/document/apn/an023-low-cost-digital-panel-meter-designs-and-complete-instructions-lcd-and-led-kits?language=en|AN023 Low Cost Digital Panel Meter Designs and Complete Instructions for LCD and LED Kits}}{{electronic:equipment:icl7106:idt_an023_apn_19990330.pdf|.}} * {{https://www.renesas.com/sg/en/document/apn/an046-building-battery-operated-auto-ranging-dvm-icl7106|AN046 Building a Battery Operated Auto Ranging DVM with the ICL7106}}{{electronic:equipment:icl7106:idt_an046_apn_19990513.pdf|.}} * {{https://www.renesas.com/sg/en/document/apn/an052-tips-using-single-chip-3-12-digit-ad-converters|AN052 Tips for Using Single Chip 31/2 Digit A/D Converters}}{{:electronic:equipment:icl7106:idt_an052_apn_19990423.pdf|.}} * [[:electronic:datasheet:intersil|7106/07 Datasheets]] * [[https://hackaday.com/2020/09/24/in-praise-of-the-dt830-the-phenomenal-instrument-you-probably-dont-recognise-for-what-it-is|DT830]] classic multimeter that uses ICL7106 (hackaday.com). * [[https://www.hobby-hour.com/electronics/icl7106.php|ICL7106 DVMs]], links to schematics (hobby-hour.com). * [[https://www.petervis.com/meters/ICL7106%20and%20ICL7107%20Digital%20Meter/ICL7106%20and%20ICL7107%20Digital%20Meter.html|An ICL7106 and ICL7107 Digital Meter design]] * [[https://hackaday.com/2017/01/31/get-to-know-3%C2%BD-digit-adcs-with-the-icl71xx/|ICL71xx]] including a bit of history (hackaday.com).
