The JFET-input operational amplifiers in the TL07x series are designed as low-noise versions of the TL08x series amplifiers with low input bias and offset currents and fast slew rate. The low harmonic distortion and low noise make the TL07x series ideally suited for high-fidelity and audio preamplifier applications. Each amplifier features JFET inputs (for high input impedance) coupled with bipolar output stages integrated on a single monolithic chip.
These pages created by Wichit Sirichote of Department of Applied Physics, Faculty of Science, provides schematic and software for hobbyists to practice "learn by doing", build a simple microcontroller projects at home.
"I do remember the Intersil ICL7135 very clearly. This year 2011, almost 29 Years, the classic integrating type analog to digital converter is still interested. With a cheap price and easy interfacing, I think I will design a cheap digital volt meter with microcontroller to provide serial interface similar to the Fluke45. Two channels is good for scientific experiment."
Developer and fabless manufacturer of a class of reconfigurable hardware chips known as field-programmable gate arrays (FPGAs). It was founded by Ross Freeman (FPGA inventor), Bernie Vonderschmitt (fabless pioneer), and Jim Barnett in 1984 and was based in Silicon Valley.
Product Line include Programmable FPGA, 3D IC, SoC, CPLD and Configuration Memory solutions. Embedded Processing, DSP and Connectivity Solutions. An extensive catalog of base-level cores is available to address the general needs of all designers.
The Evaluation Kit includes all the basic components of hardware, design tools, IP, and pre-verified reference designs including a targeted design, enabling a complete embedded processing platform. The included pre-verified reference designs and industry-standard FPGA Mezzanine Connectors (FMC) allow scaling and customization with daughter cards.
