Positive to Negative Converter with Variable Output Using LTC3630 and LT6015/LT6016
Sep 1st 2015
There was a window of time in the 1950s and early ’60s when negative voltage rails were commonplace, when germanium PNP transistors were prevalent—like those used in an old “transistor radio”, now worth a fortune on Ebay. Nowadays, NPN transistors are more prevalent, since they basically work ...
LTC2644 An Opto-Isolated, PWM Regulated 4mA to 20mA Process Controller
Aug 4th 2014
The LTC®2644 is a family of dual 12-, 10-, and 8-bit PWMto- voltage output DACs with an integrated high accuracy, low drift, 10ppm/°C reference in a 12-lead MSOP package. It has rail-to-rail output buffers and is guaranteed monotonic. ...
LTC2645 An Opto-Isolated, PWM Regulated 4mA to 20mA Process Controller
Jul 21st 2014
The LTC®2645 is a family of quad 12-, 10-, and 8-bit PWMto- voltage output DACs with an integrated high accuracy, low drift, 10ppm/°C reference in a 16-lead MSOP package. It has rail-to-rail output buffers and is guaranteed monotonic. ...
DAC Reference Inverter and I-to-V Converter
Aug 23rd 1995
LT6011 dual op amp performs two functions - inverting a positive ref voltage to a negative ref voltage to allow bipolar output polarities and performing the current to voltage conversion on the DAC's current outputs as well buffering the outputs. ...
LTC1453/LT1077/LT1121 Isolated 4 – 20mA Current Loop
Jan 1st 1987
This circuit is a computer-controlled 4 – 20mA current loop. It is designed to operate on a single supply over a range of 3.3V to 30V. The circuit’s zero output reference signal, 4mA, is set by R1 and calibrated using R2, and its full-scale output current is set by R3 and calibrated using R4. The zero and full-scale ...
