The small total component count, the low cost, and high reliability allow for a wide variation in display applications, especially those previously utilizing APM's (Analog Panel Meters). The technology utilized in the AD2020 is Integrated Injection Logic (I2L), an extension of the long proven, high yield bipolar process. This technique offers a significantly higher circuit packing density. The input amplifier, comparator, band-gap reference, counters, clock, control logic, multiplexer and drivers needed to implement the dual slope conversion, are all included on a single die. The AD2020, although it has an internal reference, consumes only SOmW of power and is operated from a single +5V supply, unlike most DPM chips requiring two (2) supplies. The DPM chip is packaged in a standard size 16 pin-dual-in-line package. Utilizing a unique double passivation and noble-met...
