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.

wonderful - best dog toy on the market!!
Style: Chilly Penguin, Size: Small (Pack of 1), Style: Chilly Penguin, Size: Small (Pack of 1)
my 10.6 lb shih tzu mix loves these. yes, they are durable. this is the third dog on some of them. i fill with diluted baby food mixed with 3 drops honey, carrots in todays, or peanut butter and a tad of jelly mixed with water, or water with unsalted cooked veggies like broccoli or cauliflower stems and carrot bits, or baked and mixed with water sweet potato. she eats just anout any vegetable. the water is to reduce calories as i had to take 3 lbs off her when i got her. and yes, they stack nicely.
when i let her out of her crate, she looks and grabs it and puts it on the kitchen floor for a refill. her idea, not my training but i like it.
this is an addition to my previous review. as far as i'm concerned, this is the best toy on the market for very small dogs. my dog has been at target weight for 2 years now and i restrict her treat calories to a strict 21 kcals daily. she is also now a working dog. i have now done frozen greek yogurt with apples and blueberry baby food diluted, kibble mixed in water. wet dog food diluted with water etc. i leave her in her crate with one and two cameras on her, one two way audio and she has stopped all barking and dutifully brings the toy and actually deposits it in my hand when i let her out of the crate. every 2-3 days it's like a new toy flavor and no toys have and tooth marks or anything on them. they're used daily.
understand this lil 10.6 lb dog goes thru nylon power chews regularly so she's super capable of destroying toys but i think the little bit of food satisfies her with the penguin and 2 1/2 years in, she has no desire to destroy them. i now own 8 of these as 2 stay in her travel bag.
we would be heartbroken if the company quit making these penguins. fantastic product. the small would even have worked for my 5 lb papillons had they made them then.

Great durability and utility
Style: Chilly Penguin, Size: Medium/Large (Pack of 2)
I love the size of these and the sturdiness. I freeze bone broth and put it in the crate or give it to dogs when it gets warm out. To help them cool or help them with teething. They have decimated other holders of frozen liquid, but these have lasted well. They also do not get sharp edges when chewed on by English bulldogs.

Its a hit for my 9lb chewer!
Style: Chilly Penguin, Size: Small (Pack of 1)
So far so good! My Pup is a chewer and destroys most of his toys. This has been great to keep him happy and occupied for about an hour. I work from home, so when I know I need to keep him busy this is perfect. Ill keep an eye on it to make sure he doesn't break it, but it is pretty solid and thick. He can get through a puzzle in seconds, so this has been so good for him. Ive done mostly broth and veggies, some kibble. Even yogurt and peanut butter. Right now he gets it twice a day. He spends about an hour with it and then hes so tired hes ready for a nap. Once around mid day and another late evening before bed. Im ordering another to keep for when I have to leave him home alone.
He cleans it pretty well, but Ive found soaking in hot water also loosens any bits left behind. Because its small, I'm not worried about extra calories.
