The AD5932 is a waveform generator providing a programmable frequency scan. Utilizing embedded digital processing allowing enhanced frequency control the device generates synthesized analog or digital frequency-stepped waveforms.

AD5932 – Programmable Single-Scan Waveform Generator

This product from Analog Devices is Active. Sinusoidal/triangular/square wave outputs. Output frequency up to 25 Mhz.

XR2206 – Monolithic Function Generator

The XR2206 is a monolithic function generator integrated circuit capable of producing high quality sine, square, triangle, ramp, and pulse waveforms of high-stability and accuracy. The output waveforms can be both amplitude and frequency modulated by an external voltage. Frequency of operation can be selected externally over a range of 0.01Hz to more than 1MHz.

Appears to be Active – Earlier it was not so.

XR2209 Voltage-Controlled Oscillator

The XR2209 is a monolithic voltage-controlled oscillator (VCO) integrated circuit featuring excellent frequency stability and a wide tuning range. The circuit provides simultaneous triangle and squarewave outputs over a frequency range of 0.01Hz to 1MHz. It is ideally suited for FM, FSK and sweep or tone generation, as well as for phase-locked loop applications. Waveform Generation Triangle, Sawtooth, Pulse, Squarewave.

This is Available at Digikey – FUNCTION GENERATOR 16PDIP – XR2209CP-F

ICL8038 Precision Waveform Generator/Voltage Controlled Oscillator

The ICL8038 waveform generator is a monolithic integrated circuit capable of producing high accuracy sine, square, triangular, sawtooth and pulse waveforms with a minimum of external components. The frequency (or repetition rate) can be selected externally from 0.001Hz to more than 300kHz using either resistors or capacitors, and frequency modulation and sweeping can be accomplished with an external voltage.

delabs Notes

This was one of my favorite chips. This is of educational value. It was a pioneer chip a mixed cmos device. Make it a point to read the Datasheet. Chip may have been invented 1980 around. This is study material for college.

It is not available in stores. Some EE Engineer or Ham-DIY Enthusiast may have a few. Borrow and try it out for learning. If you blow the chip, try saying sorry.

Advanced Students can try configuring it in a Programmable Mixed Chip EDA tool plugin, if someone has developed that. Try taking a draft output on a semiconductor laser nano-milling prototype printer with a built in Mems pico-doper. If that works, lets go foundry!
