It samples at 16 conversions per second, accepting a single differential input and outputting data over a parallel interface. ## Dual ±5 V rails and external reference Both the analog and digital supply pins need ±5 V — there is no single-rail version of this part. That means a bipolar supply on the board, or a DC-DC converter generating the negative rail. ## Through-hole PDIP — rework-friendly, socketable The 28-pin PDIP (0.600\" wide, 15.24 mm pitch) is about as rework-friendly as it gets. No hot air needed — a desoldering station or even a solder sucker will lift this cleanly. If you are prototyping or building a low-volume run, you can socket this in a 28-pin DIP socket and swap parts without touching the board. ## Lifecycle and sourcing The MAX135CPI+ carries an Active lifecycle status and is ROHS3 compliant. For a precision ADC in a through-hole package that has been around for years, that is a solid sourcing position — no urgent need to qualify a second source, though the 28-pin DIP footprint is common enough that a pin-compatible alternative from another vendor could be dual-sourced if supply risk is a concern.","metaTitle":"MAX135CPI+ 15-bit Multi-Slope ADC, 16 S/s, 28-PDIP","metaDescription":"MAX135CPI+ 15-bit multi-slope ADC from Maxim Integrated.

You must supply a precision reference voltage — the ADC does not include an internal bandgap reference."},{"question":"What is the closest pin-compatible alternative to MAX135CPI+?","answer":"The MAX135CPI+ sits in a small family of multi-slope ADCs from Maxim. A direct pin-compatible sibling is the MAX136CPI+ (3.5-digit version, same footprint and supply). For a 15-bit part, the MAX135 is the primary option in that DIP package; no second-source vendor lists a drop-in equivalent under a different brand."},{"question":"What is the sampling rate of MAX135CPI+?","answer":"The MAX135CPI+ samples at 16 conversions per second. This is a multi-slope integrating ADC — the low rate is by design, giving excellent noise rejection on slow signals."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX135CPI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX135CPI when reusing this data.
