I tried TLC numbers MC numbers but couldn't find any IC in local shops. ordering such IC from another country is not an option as it takes about 3 weeks to receive.MCP6021
can someone please suggest me opamp with above specs
Slew rate 7V/µs
Operating voltage, 2.5V to 5.5V
And since it's a Microchip part, it's as common as PIC's
You can have it in a range of houses, from a common PDIP-8 down to a 5-pin SOT-23
I don't know how fast they operate in your end of the world, but try here for a couple of samples:
Microchip Technology (India) Private Ltd.
India Design Center
Plot No. 149-B. EPIP Phase Industrial Area,
Bangalore, 560 066
Phone: +91-80-3090 4444
Fax: +91-80-3090 4123
I've gotten samples made halfway around the world in 2..3 days from ordering.
Since I don't know what's in your local store, I have no chance of guessing what might fit, if any - your demands are a bit steep for the average hobbyist op-amp.
If you have a list of what they have in store, I could glance through it and see if anything pops up.
I'd try the local (sort of) Microchip Sales Office first though.
You could call the various local sales representations for major chip manufacturers and ask politely if they have something you could use - in any case, it's good to make some contacts in the trade you're heading towards and most can be persuaded to send a few chips to an interested student - also good for future projects.
