MAXIM INTEGRATED PRODUCTS MAX1473EUI+ IF RECEIVER, 300MHZ-450MHZ, TSSOP-28The MAX1473EUI+ is a 315MHz 433MHz ASK superheterodyne receiver with extended dynamic range in 28 pin TSSOP package. This fully integrated low power CMOS receiver is ideal for receiving amplitude shift keyed (ASK) data in the 300MHz to 450MHz frequency range. Its signal range is from 114dBm to 0dBm. With few external components and a low current power down mode it is ideal for cost and power sensitive applications typical in automotive and consumer
The MAX1473EUI+ is a 315MHz/433MHz ASK superheterodyne receiver with extended dynamic range in 28 pin TSSOP package. This fully integrated low power CMOS receiver is ideal for receiving amplitude shift-keyed (ASK) data in the 300MHz to 450MHz frequency range. Its signal range is from -114dBm to 0dBm. With few external components and a low current power down mode it is ideal for cost and power sensitive applications typical in automotive and consumer markets. The chip consists of a low noise amplifier LNA , a fully differential image rejection mixer, an on-chip phase locked loop with integrated voltage controlled oscillator, a 10.7MHz IF limiting amplifier stage with received signal strength indicator and analogue baseband data recovery circuitry. It also has a discrete one step automatic gain control that drops the LNA gain by 35dB when the RF input signal is greater than -57dBm. It is used in automotive remote keyless entry, garage door openers, remote controls & home automation.
- Operates from single 3.3V or 5.0V supplies
- Operating temperature range from -40°C to 85°C
- Receiver input frequency range from 300MHz to 450MHz
- High dynamic range with on-chip AGC, selectable image rejection centre frequency
- Selectable x64 or x32 fLO/fXTAL ratio
- Low 5.2mA operating supply current
- Low current power down mode for efficient power cycling < 2.5µA
- 250µs start-up time, built-in 50dB RF image rejection
- Receive sensitivity of -114dBm

Oil and fragrance free for sensitive skin
Oil free which is good for contact lens wearers. Relatively thick textured material so I can use just one pad for both eyes. Ok for sensitive skin with no fragrance. I've used these for years and the quality has remained consistent despite the reasonable price.

A 5-star product is now barely 2-stars. Shame!
I have used these makeup remover pads for years as I wear contacts and have sensitive skin around my eyes. However, the last 3-pack I ordered (Feb 2026), the pad is noticeably sub-par. They are much thinner, there is no quilted texture on one side, and they roll up immediately when you start to rub your eyes with them. In addition, I have to use 4-5 pads to get everything off vs. previously I could easily just use one on each eye. Obviously I will go through them much faster and every time I use them, I get frustrated by how bad the quality is now. Another product victim to shrinkflation and using cheaper materials, but charging the same amount or more than before.
Do they do the job removing the makeup - yes.
Do they do so without burning my eyes or leaving an oily residue - yes.
But knowing how great they used to be, I can only give the current product 2 stars.

Excellent product!
I have used this product for years but since retired much less. However when I actually needed it again I couldn't find it anywhere and when I did buying just one was pretty expensive. So I decided to wait until the price dropped...but it never happened. I never even thought of trying Amazon but I did and got an amazing deal of a 3 pack at a very reasonable price. The oil is rich, soothing and so emollient and cleans my brows and eye lashes perfectly! I keep one in my fridge which is especially soothing during warm summer days and helps to reduce under eye puffiness. Accolades to Amazon...you never let me down!

The perfect toy for dogs!
Style: The Duo
This is perfect when you have 2 dogs who love to play Fetch! They no longer have to chase after the same ball! The balls that come with it are very sturdy, and the launcher sends both balls far enough away so that both dogs get plenty of exercise. It’s definitely worth the price!

PERFECT RETRIEVING TOY
Style: EcoFetch
You can barely whip it and it sails far and fast. This is the perfect retrieving toy for my GSP. She's used to average and we now have a small yard, so the dog park is where she gets to run hard and fast. You can also throw tennis balls with it, which is a plus for when her sister steals her ball.
5 star fun!
