The ADC80, made by Analog Devices as well as other manufacturers, is a 12 bit successive approximation analog to digital converter. Analog Devices touts the ADC80's lack of reliance on external components; it's clear this was accomplished by physically relocating components to the interior of the IC package. The ADC80 makes use of a large specialized carrier, which contains six integrated circuit dies as well as a number of lesser components. The carrier also contains a laser trimmed 6.3 volt zener diode reference source, which is accessible through an external pin on the package. The ADC80 seems to have gone through significant package variation over the years, with early examples being packaged in a purple ceramic bathtub carrier with bottom brazed pins. Later versions are packaged in more traditional flat ceramic carriers with a hollow ceramic lid covering the cavity. The example shown here a metal cavity variation, which replaces the ceramic cavity lid with a metal lid and gold-lined cavity.

The ADC80 is built as a hybrid microcircuit in a ceramic carrier, and contains six integrated circuits as well as a number of smaller components.

The ADC80 was manufactured in a number of different cosmetic variations. Here a metal cavity lid version is shown next to a ceramic lid version.

The ADC80 was produced in a number of different packages variants. These examples are constructed on ceramic wafers with bathtub style lids.
