MAX038CPP+

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX038CPP+ is a discontinued high-frequency precision function generator integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It generates sine, square, triangle, sawtooth, and pulse waves with an output frequency range of 0.1 Hz to 20 MHz, extending up to 40 MHz. The device features independent frequency and duty cycle control, low total harmonic distortion (0.75% typical for sine waves), and low temperature drift (200 ppm/°C). It operates on dual ±5V power supplies within a specified voltage range of ±4.75V to ±5.25V. The component is housed in a 20-pin PDIP package and supports operation across a commercial temperature range of 0°C to +70°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

The MAX038CPP+ is officially listed as discontinued by the manufacturer. Availability is restricted to remaining stock or obsolete channels. Verification of authenticity and physical condition is critical when sourcing from third-party distributors due to the end-of-life status. Buyers should confirm the specific package variant and manufacturing date code prior to acquisition.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Designers replacing this component must account for its discontinuation. Digital alternatives like the AD9833 offer programmable frequency synthesis but require different interface logic. For direct analog replacement, older models like the ICL8038 provide similar functionality but with significantly lower maximum frequencies around 300 kHz. PCB layout requirements for high-frequency stability remain relevant for any substitute function generator IC.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MAX038 family of function generator ICs, which succeeded earlier designs like the ICL8038 by offering higher frequency ranges and improved accuracy. The 'CPP' suffix indicates a plastic DIP package with a specific operating temperature range. The '+' suffix denotes compliance with current environmental standards. The component represents a standard solution for analog waveform generation before the widespread adoption of direct digital synthesis techniques.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Publicly confirmed substitutes include the AD9833 for digital synthesis applications and the ICL8038 for legacy analog compatibility. No direct pin-for-pin active replacements are documented in public sources for the MAX038 family.
