It integrates the ADC core, display drivers, and reference onto a single chip — a legacy workhorse for panel-meter and data-acquisition designs that need a direct digital readout without an external microcontroller. With two input channels and a single-supply range of 2.5 V to 7 V, it handles ratiometric measurements from bridge sensors or potentiometers. ## Package and supply rails The 40-pin PDIP (0.600-inch row spacing) is a through-hole package — it protrudes through the board and requires a wave-solder or hand-solder step. No MSL floor-life concern: the PDIP body is moisture-insensitive, so no bake-out before assembly even after extended storage. Supply voltage spans 2.5 V to 7 V, single supply only. The 3.5-digit resolution (~±1999 count full scale) is typical for a dual-slope integrating ADC — the integration period rejects 50/60 Hz line noise when the clock is set to an integer multiple of the mains period.","metaTitle":"MAX138CPL+ ADC, 3.5 Digit, 2-Ch, 40-PDIP","metaDescription":"MAX138CPL+ ADC from Analog Devices, 3.5 digit resolution, 2 channels, 2.5V to 7V supply, 40-PDIP.
