ICL7660CPA : Voltage Inverter, +5 to +/-5V, Input Voltage 1.5-10V, or Voltage Doubler to 18.6V

On offer are 10 new (old stock) pieces of the classic Intersil brand Voltage Converter, type ICL7660CPA. This is a very handy chip for efficiently (98%) generating bias voltages for FETs and negative power rails for Op Amps from a single supply, such as in battery powered equipment.

  • Simple to use - requires only a couple of external capacitors.
  • Versatile - can be paralleled for more power, or cascaded for higher voltages.
  • Application circuits abound on the Internet.
  • As with most DIP packages, increasingly hard to source.

My most common use for these parts is for conveniently generating the negative bias supply in GaAsFET circuits. A typical example is the GaAsFET preamp bias board, by Paul Marsh, M0EYT. Other examples are

Worth picking up a few for the parts drawer!

The ICL7660A performs supply voltage conversions from positive to negative for an input range of +1.5V to +12.0V resulting in complementary output voltages of -1.5V to -12.0V. Only 2 noncritical external capacitors are needed for the charge pump and charge reservoir functions. The ICL7660A can also be connected to function as a voltage doubler and will generate output voltages up to +18.6V with a +10V input.

About RFPlus

RFPlus is back in the UK after a few months in Australia ... and starting to settle in. Unpacking continues. In the meanwhile I'm going to have to pull myself back into the black (I now know just how expensive it was to move several tonnes of stuff halfway around the world) so I hope you'll find something of interest amongst my listings. Thanks as always to all of you who've supported me by buying my spares, particularly over the past few months!

For other info, visit my the 'About Me' page. If you're thinking of bidding/buying I'd ask that you visit that page at least once so you can read the 'Terms & Conditions' and a bit more about RFPlus.

Seller's payment instructions
Paypal is probably the quickest and most convenient way to pay, wherever you are. For UK customers, payment may also be made via direct transfer into a UK bank account, or by personal cheque or Postal Order in UK pounds. For Australian customers, payment may also be made via direct transfer into my Australian bank account (and you can save a little money by avoiding Paypal's exchange rates). Please get in touch for address/bank details. I will wait for funds to clear before posting.
