CotW: MAX2606

Congratuations MAX2606, you are the Chip of the Week!

This week’s CotW is the MAX2606, a little IC I’ve used in a bunch of projects. This chip is part of a family of FM modulator ICs, produced by Maxim. The MAX2606 in particular has a range of 80-100MHz, right in the audio FM band. Basically, If you’ve ever wanted to stick an FM (audio) transmitter in something, this is a cheap/small/simple solution. Theres even a great app. note with a working schematic.

  • Pros: Super cheap, super small, works great, 3V
  • Cons: SOT-23: a bit too small, can’t buy it from traditional outlets (but you can sample nearly as many as you want from Maxim), a bit quiet

Notes:

  • Don’t forget to put 1% resistors in the tuning: the drift will kill you!
  • Attenuate the input to like 50mVpp (?)

Tune in next week for another Chip of the Week!


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
