INTERSIL CA3140EZ Operational Amplifier, Single, 1 Amplifier, 4.5 MHz, 9 V/µs, 4V to 36V, DIP, 8 PinsThe CA3140EZ is a BiMOS operational amplifier with MOSFET input bipolar output in 8 pin DIP package. It combines advantages of high voltage PMOS transistors with high voltage bipolar transistors on a single monolithic chip. This BiMOS operational amplifier has gate protected MOSFET (PMOS) transistors in input circuit to provide very high input impedance, very low input current and high speed performance.

The CA3140EZ is a BiMOS operational amplifier with MOSFET input/bipolar output in 8 pin DIP package. It combines advantages of high voltage PMOS transistors with high voltage bipolar transistors on a single monolithic chip. This BiMOS operational amplifier has gate protected MOSFET (PMOS) transistors in input circuit to provide very high input impedance, very low input current and high speed performance. The CA3140EZ is internally phase compensated to achieve stable operation in unity gain follower operation. It has access terminal for supplementary external capacitor if additional frequency roll off is desired. The output stage uses bipolar transistors and includes built-in protection against damage from load terminal short circuit to either supply rail or to ground.
- Gain bandwidth product of 4.5MHz
- Supply voltage from 4V to 36V
- Slew rate of 9V/µs
- Input offset voltage of 5mV at Vs = ±15V
- Input offset current of 0.5pA at Vs = ±15V
- Common mode rejection ratio (CMRR) of 90dB at Vs = ±15V,
- Operating temperature range from -55°C to 125°C
Applications
Signal Processing, Portable Devices
Warnings
This device is sensitive to electrostatic discharge. Users should follow proper IC handling procedures.

Colorful, comfortable, durable water shoes
Size: 8.5-9.5 Women/7.5-8.5 Men, Color: Shark Blue, Size: 8.5-9.5 Women/7.5-8.5 Men, Color: Shark Blue
I have ordered 5 pairs of these water shoes. The quality is amazing the bottom is durable, the stitching feels strong, they are comfortable, slip resistant, fit true to size and look awesome!
We ordered the paisley, the blue geo, galaxy, lightning (lightning was sent back as we received the wrong size) and sharks.
Only reason they are getting a 4 star instead of 5 is because I would much rather have the cushion inside sewn in instead of it being like an insert but that is what I find to be most common with these type of shoes.

Love these for beach foot protection!!
Size: 10-11 Women/9-10 Men, Color: Black-w001
These water shoes were perfect for our cruise to Grand Turk. The beach was a little rocky once in the water & the bottom of these shoes protected our feet and made it comfortable they dry quickly they are lightweight and easy to pack and carry in a beach bag. I bought two pair of the black one for me one for my husband, and he even wore them which was shocking into me and loved them.!!!! they don’t have walking support so they’re definitely something that you bring with you put on your feet before you enter like water where you can’t see the bottom or rocks/coral and they totally protect your foot on the bottom

I received someone else’s returned product
Size: 7-8 Women/6-7 Men, Color: Sunset
The inner product packaging was already cut open and not sealed, and there was debris inside the socks: clear indicators that the pair I received was someone else’s return. They also run big and are very wide in the toe area. My daughter’s pair also ran big, but at least hers were sealed. Overall quality is a bit flimsy, so we’ll see how long they last.

Decent water shoe
Size: 10-11 Women/9-10 Men, Color: N-laser Stripe
I have to admit, I was a bit skeptical about the quality of and comfort of these shoes because of the cheap price. However, I really do like them. They stay on my feet, are comfortably and non-binding, which is saying something because my feet have been pounded over the years. They even did well when I had to cross some rocks, trekking back to the kayak. Definitely a gods water shoe for a good price.

Perfect!!!
Size: 7-8 Women/6-7 Men, Color: Black-w001
I absolutely love these water shoes. I wear them around the house, getting out of shower, even outside.
I’m a stroke survivor that was paralyzed. One of the biggest hurdles of walking again is feeling the ground . One day I thought water shoes would work. After trying a few types I fell in love with these. So easy to put on. Comfortable. Feels one nothing on . I’m buying in multiple colors . Love love love these. Game changer for someone learning to walk again. My feet don’t sweat in them . I wear with and without socks . Easy to wash quick to wrong put and dry. Non slip.
