This document describes a new method of accessing IEEE 1149.1 based-boards in the backplane environment. The method can be used with a simple backplane to board connection or expanded to include the commandable features useful in the backplane environment. The document provides details on the addressable shadow port (ASP) and the shadow protocol that provide the means of connecting the backplane a

TPS51220 Independent Rail Dual Buck Converter using TPS51220

The PGA309 programmable gain amplifier generates three primary types of noise: broadband noise noise from the instrumentation amplifier auto-zero circuit and noise from the Coarse Offset auto-zero circuit. Noise at the PGA309 output can be reduced by limiting the bandwidth with a simple filter. This application note describes how to select the filter components in order to get the desired bandwi

Optimizing MOSFET Characteristics by Adjusting Gate Drive Amplitude

Analog designers are frequently required to develop circuits that convert high-voltage signals to levels acceptable for low-voltage data converters. This paper describes several solutions for this common task using modern amplifiers and typical power supplies. Five examples of conditioning ±10V bipolar signals for low-voltage single-rail analog-to-digital converters(ADCs) are presented:

Conventional regulators have a high drop-out voltage that is a function of the total output current.However with just a regulator chip an external transistor and a few passive components this designforms a high output current regulator with a limited input voltage and high efficiency. The circuit presentedhas a drop-out of 0.7V at 5A load current and 1.3V at a current level of as high as
