The MAX1932ETC+ is a digitally controlled, 0.5% accurate, safest APD bias supply in 12 pin TQFN package. It generates low noise, high voltage output to bias avalanche photodiodes (APDs) in optical receivers. Very low output ripple and noise is achieved by a constant frequency PWM boost topology combined with a unique architecture that maintains regulation with an optional RC or LC post filter inside its feedback loop. The output voltage can be accurately set with external resistors, internal 8bit DAC, external DAC or other voltage source. This optimizes utilization of DAC resolution for applications that may require limited output voltage range such as 4.5V to 15V, 4.5V to 45V, 20V to 60V, or 40V to 90V. Protection features provides safe operation, accurate high side current limit, avalanche indicator flag. It is used in optical receivers and modules, fibre optic network equipment, telecom equipment, laser range finders and PIN diode bias supply.
- Input supply voltage range from 2.7V to 5.5V & operating supply current of 1mA at TA = -40°C to 85°C
- Operating temperature range from -40°C to 85°C
- Unique architecture delivers excellent accuracy for improved system performance
- Precision reference and error amplifier maintains 0.5% output voltage accuracy
- Protects expensive APDs against adverse operating conditions while providing optimal bias
- Output voltage flexibility facilitates multiple applications and design approaches
- Output voltage via 8bit SPI compatible
- Small circuit footprint reduces equipment size
- VIN maximum shutdown supply current of 65µA at TA = -40°C to 85°C
- Switching frequency range from 240KHz to 360KHz at TA = -40°C to 85°C

Absolutely Essential for Any Athlete or Gym-Goer!
Size: Large, Color: (035) Steel / White / Black
I recently purchased the Under Armour Unisex-Adult Training Cotton No Show Socks 6 Pack, and I must say, they've become an indispensable part of my workout gear. Here's why these socks are a game-changer:
Comfort Above All: These socks are incredibly comfortable. Made from a blend of cotton and synthetic fibers, they provide just the right amount of cushioning without feeling bulky. Whether I'm running, lifting weights, or doing yoga, my feet feel supported yet free.
No Show, All Go: True to their name, these socks stay perfectly in place without slipping down into my shoes. This is crucial for maintaining a professional look at the gym or during sports activities. No more embarrassing sock peeks or having to constantly adjust them.
Durability: For the price, these socks hold up remarkably well. I've washed them multiple times, and they haven't lost their shape or elasticity. They've survived the rigors of both my workouts and laundry day.
Breathability: The material mix allows for excellent breathability. My feet stay dry and cool, reducing the chances of blisters or discomfort during long sessions.
Pack Value: Getting six pairs in one go is fantastic. It means I always have a fresh pair ready, which is perfect for someone like me who works out frequently.
Fit for All: These socks fit true to size and are designed to be unisex, making them a versatile choice for anyone looking to upgrade their sock game.
If you're in the market for socks that combine comfort, performance, and style, look no further. Under Armour has nailed it with these no-show socks. They've quickly become a staple in my wardrobe, and I find myself reaching for them over any other sock I own. Highly recommended for anyone serious about their fitness routine or just wanting reliable, high-quality socks.
