What is this IC?

[Demon]

I think it's the old markings for a MCP614x op-amp. I "had" labeled the drawer as an op-amp.

I know it's 8-lead, pretty sure it's msop, but it can be any of MCP6141, MCP6142 or MCP6143.




I checked my order history at Digikey, Mouser, Newark, MicrochipDirect, even eBay, Amazon and AliExpress. No clue where I got these. I'm guessing a "lot purchase" on ebay a long time ago.

Here's another one for you.

I have it labeled as 1680FP-3 sensor actuator; no datasheet on hand either. I think they were samples cause they're in a Dallas/Maxim plastic box (now Analog). I vaguely remember going on these sites and ordering whatever free samples I could get.




Nowhere to be seen on google, except from what appears as warehouses in Asia:

- https://cn.exshinetech.com/products/1680FP-3.html
- https://www.abc-semi.com/products/C3A/1680FP-3.html

They have it labeled as QFP by Dallas, but their datasheet links are dead.

DS1680FP-3 Product details
DESCRIPTION
The DS1680 incorporates many functions necessary for low-power portable products, providing an RTC, NV RAM controller, microprocessor monitor, power-fail warning, 10-bit ADC, and a touch-screen controller in one chip.

FEATURES
■ Real-time clock (RTC)
- Counts seconds, minutes, hours, date, month, day of the week, and year with leap-year compensation valid up to 2100
- Power control circuitry supports system power-on from day/time alarm
■ Microprocessor monitor
- Halts microprocessor during power-fail
- Automatically restarts microprocessor after power failure
- Monitors pushbutton for external override
- Halts and resets an out of control microprocessor
■ NV RAM control
- Automatic battery backup and write protection to external SRAM
■ 1.25V threshold detector for power-fail warning
■ 10-bit analog-to-digital converter (ADC)
- Monotonic with no missing codes
■ Four-wire analog resistive touch-screen interface

Woot! Thanks!

And yet I screwed up cause I never use 3.3V, I should have taken the DS1680FP-5.

Drawer label said "wires".

I figure some sort of capacitor, not sure which variety.






And as I'm typing this I'm still googling and found this:

https://datasheets.kyocera-avx.com/SR-Series.pdf

105 = 1uF
E = Z5U
5 = 50V
M = 20%

I think it's SR215E105M or SL215E105M (mainly cause it's industry standard). The only thing that bugs me is that the dimensions are off, mine are:

6.25mm wide
7.1mm tall
3.1mm thick

That doesn't quite line up with any of them...?

EDIT: I'm sure I got this recently, and no orders matching this in 1uF from Digikey, Mouser or Newark.

Is the 451 marking in the back of the 1uF cap? If not, then it should be a 45 x 10pF = 450pF cap. I bought a leaded cap assortment one time, and it was a pain separating them by value. Some markings are not too obvious.

Yeah, that's both faces of the same cap.

I'm "pretty" sure it's Kyocera. That post on MakerPro IDed the logo. Use the original link I got from google search:

I use GENERIC on all my bulk purchases, with the most conservative ratings possible. ut this is a recent purchase, very possible at a local store with the specs got torn off when I opened the bag.

I'd really like to make an accurate label if at all possible.
