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

Comfortable fit for slip-in fabric shoes
Size: 14, Color: Black/Black
My first experience with Marc Joseph. I typically purchase dress and casual work shoes from Florsheim and occasionally Rockport. I'm giving these four stars because the initial fit and feel appear solid. Depending on the shoe brand I wear a size 14 or 15. My feet are slightly wide but I don't alway need wide fit. These size 14 fit well with wide enough toe box. I've tried slip in shoes before and they just don't feel right. These somehow work and there is no heel slip. My only reservation is the high lip on the heel for slip-in and hope they dont catch pant hems. I gave 4 stars because I'll have to determine durability. Granted they are a light fabric shoe with a soft rubber tread. I'd like them to last for at least 6 months..and use them for business casual work wear during warm weather.
