MAX038CPP

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX038CPP is a high-frequency precision function generator integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It produces accurate triangle, sawtooth, sine, square, and pulse waveforms with an operating frequency range of 0.1 Hz to 20 MHz. The device features independent frequency and duty-cycle adjustments, allowing for precise control over waveform characteristics. It utilizes an internal 2.5V bandgap voltage reference and external components for frequency setting. The output buffer provides low impedance (0.1 Ω) and supports a variable duty cycle from 15% to 85%. The component is housed in a 20-pin PDIP package and operates on dual power supplies.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

The MAX038CPP is listed as obsolete or discontinued by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or surplus market sources. No new production units are expected. Buyers should confirm the specific revision and packaging condition before acquisition due to the end-of-life status.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the MAX038CPP when a standalone IC solution for generating high-frequency analog waveforms is required without complex external logic. It is suitable for designs needing independent control of frequency and duty cycle. Consider the 20-pin PDIP package constraints and dual supply voltage requirements during PCB layout. Verify that the 20 MHz maximum frequency meets the application's bandwidth needs.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The MAX038CPP belongs to the MAX038 family of high-frequency waveform generators. It shares functional specifications with other variants such as the MAX038CWP and MAX038CCP, differing primarily in package type and temperature rating. The CPP designation indicates a plastic DIP package. This series was designed to replace older function generator chips with higher frequency capabilities and improved accuracy.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-to-pin replacements may be limited due to the component's discontinued status. Evaluate alternative function generator ICs from current product lines if long-term supply stability is required. Ensure any substitute matches the 0.1 Hz to 20 MHz frequency range and waveform types.
