Does 8-pin MCU with 10-bit DAC even exists?I think some simple 8pin microcontroller with 10-bit DAC is the easiest solution you can have.
However, it's no problem to build a function generator down in the millihertz range. Check out "Lock-in" amplifiers.Be realistic. No oscillator can generate 0Hz.
Voltage control? What control voltage ranges? 0~5V, 0~30V?
How good(i.e. low distortion) you would want the sine waveform to be?
5%, 1% , 0.1% or 0.001% distortion?
Thank you. But i already hav 3524. Can i use that to produce direct PWM oscillations? I dont understand the operation of sg3524. Anyways, I'll check your link.Well, you might get there with an XR-2206.
Jameco still carries them for $3.59 when you're buying singles:

You can sweep the frequency output by applying a voltage to pin 1. Not certain how far it can be swept. Sinewave output is available at around 1% distortion.
See the datasheet on Jameco's site (above link)
Also see TAN-005, attached.
It has a built-in oscillator, but it's designed for fixed-frequency operation.Thank you. But i already hav 3524. Can i use that to produce direct PWM oscillations?
Read through the applications information. Texas Instruments' datasheet for that IC has a number of helpful examples.I dont understand the operation of sg3524.
Ok. So, i think ihav to use xr- 2206. Is there any other IC readily available with regulated PWM for variable frequencies?It has a built-in oscillator, but it's designed for fixed-frequency operation.
