Description

MAXIM INTEGRATED PRODUCTS DS1859E-050+ Non Volatile Digital Potentiometer, 50 kohm, Dual, Serial, Linear, 2.85 VThe DS1859E 050+ is a dual, temperature controlled resistor with internally calibrated monitor in 16 pin TSSOP package. The DS1859 dual, temperature controlled, non volatile(NV) variable resistors with three monitors consists of two 50kohm, 256 position, linear, variable resistors, three analogue monitor inputs (MON1, MON2, MON3); and a direct to digital temperature sensor. The device provides an ideal method for setting and temperature compensating

The DS1859E-050+ is a dual, temperature-controlled resistor with internally calibrated monitor in 16 pin TSSOP package. The DS1859 dual, temperature-controlled, non-volatile(NV) variable resistors with three monitors consists of two 50kohm, 256-position, linear, variable resistors, three analogue monitor inputs (MON1, MON2, MON3); and a direct to digital temperature sensor. The device provides an ideal method for setting and temperature compensating bias voltages and currents in control applications using minimal circuitry. The variable resistor settings are stored in EEPROM memory and can be accessed over the 2-wire serial bus. Typical applications include optical transceivers, optical transponders instrumentation and industrial controls, RF power amps and diagnostic monitoring.
  • Supply voltage range is 2.85V to 5.5V
  • Operating temperature range from -40°C to 95°C
  • SFF-8472 Compatible
  • Five monitored channels (temperature, VCC, MON1, MON2, MON3)
  • Scalable dynamic range for external analogue inputs
  • Internal direct to digital temperature sensor
  • Alarm and warning flags for all monitored channels
  • Resistor settings changeable every 2°C
  • Access to monitoring and ID information configurable with separate device addresses
  • Two buffers with TTL/CMOS compatible inputs and open-drain outputs

Needs editing
Format: Kindle
Cute storyline and promising characters, but the lack of editing is painful to read. I would love to read an edited version.

A good read
Format: Kindle
A good read, just fluffy cuteness, no antagonism. I like all the characters. It could have used another round of editing however, glanfds being one error that cracked me up, and my personal pet peeve was that the author kept using the word fill instead of feel, which I promise you are not interchangeable haha, but it's definitely better than the majority of books I read on here mistake-wise.

amazing
Format: Kindle
Knot the Bride was a fantastic read! The characters were all amazing and well-developed. It was easy to like them all. Sophia, Luca, Nick, and Gavin were all perfect for each other. It was such a charming story that had me hooked the entire time. I did wish there were POVs from Luca, Nick, and Gavin but it was still an amazing book without it. I am excited to read the next book in the Willowside Omegaverse series! This is definitely a must-read for fans of omegaverse romance!. I received a free copy of this book and am voluntarily leaving a review.

3 Star Read,
Format: Kindle
This book wasn't bad, but wasn't my cup of tea. It's highly disappointing because the storyline is so original. There is no real conflict or resolution, so the entire thing feels flat. As a lover of omegaverse books, I know there is a ton of variety out there, and ov is really up to the author. But this one is weird. Omegas have multiple scent glands all over their bodies and go into week long heats every month. Alphas have knots in the middle of their shaft instead of the base, and the knot doesn't always swell, no explanation of when or why. It doesn't engage at all when the mouth is in play. I also didn't enjoy the author's writing style. Each paragraph is only 1 or 2 sentences long, and the entire book reads very stacato. The conversations are stiff and unnatural feeling. Everything is very repetitive, both in word choice and in thought. The same thing is repeated 3 or 4 times over a single page, multiple times over. I ended up doing so much skimming. The first 50% of the book is all slow burn, and the last 50% is almost straight mediocre spice. This wouldn't have been all bad if the grammar and spelling errors didn't start at the exact same time. Tongue is repeatedly misspelled in the middle of the spice.

Cozy Omegaverse
Format: Kindle
This is the true definition of Cozy Omegaverse. LA wedding coordinator meets her pack at the location for a couple’s destination wedding. Low angst because they are scent matched high heat with heats and knots. Everything you love about this genre with very little anxiety. Simply a fun experience to read and a book I will comeback to when I’m in a slump. I simply love reading this book
