Voltage to square wave

[martin griffith]

Hi.

I am looking for a way to convert 1V into 100Hz and 10V in to 1KHz
respectively. Does anyone have any simple idea's on how I might do this?

Regards

Use the VCO in the 4046 phase lock loop, it might drift a bit

Google for "voltage-to-frequency converter." National Semiconductor makes a
chip... I forget what it's called.

Google for 'voltage-controlled oscillator'.

Thanks guys, just found the LM231..... Don't know how I missed it, does
just what im after.

That is the industrial temperature range part - -25C to +85C. The LM331
is the coomercial part 0C to 70C. Cheaper, and much easier to get.
Farnell stocks the LM331 and LM331AN, but not the LM231.
