The LM136-2.5/LM236-2.5 and LM336-2.5 integrated circuits are precision 2.5V shunt regulator diodes. These monolithic IC voltage references operate as a low-temperature-coefficient 2.5V zener with 0.2 dynamic impedance. A third terminal on the LM136-2.5 allows the reference voltage and temperature coefficient to be trimmed easily.
From Signals, Filters, Sampling, Aliasing to Data Converters. This book covers the fundamentals of Mixed-CMOS Design. This book will fill a hole in the technical literature for an advanced-tutorial book on mixed-signal circuit design. There are no competitors in this area. Mixed-signal design is performed in industry by a select few gurus .

An open source USB programmer for PIC micros, I2C EEPROMs, some ATMEL micros, generic I2C/SPI devices and (soon) other devices.
"After searching a while I couldn't find an USB programmer which was at the same time functional, free, and open source, so I decided to design one. Open source means that all sources and schematics are given free of charge with the rights to modify and release them." - Alberto Maccioni
