Feedback Plots Define Op Amp AC Performance
Texas InstrumentsFeedback plots simplify the analysis of an op amp's closed-loop AC performance by showing bandwidth and stability conditions as a function of the op amp's gain and phase response. These plots also provide insight into noise performance and the special feedback requirements of circuits such as integrating converters photodiode amplifiers composite amplifiers and active feedback circuits.
TPS544Bxx/TPS544Cxx Powering TCI6630K2L in Smart Reflex Class 0 TC Mode
Texas InstrumentsThis application report describes an application circuit example of the TPS544B/Cxx family of power management IC (PMIC) powering the Smart-Reflex digital core supply of the TCI6630K2L SoC. Smart-Reflex Class 0 Temperature Compensation (Class 0 TC) mode of operation of the TCI6630K2L device is emphasized. Assumption is that temperature compensation mode is enabled using the function provided in th

Ceramic Capacitors Replace Tantalum Capacitors in LDOs (Rev. A)
Texas InstrumentsWith the proper considerations ceramic output capacitors can be used with low dropout regulators (LDO) and DC/DC switching converters that require tantulum output capacitors.
TMS320C5x Memory Paging (Expanding Its Address Reach)
Texas InstrumentsThis document discusses how the designer can extend the address space of a TMS320C5x device.Since a TMS320C5x is a 16-bit machine with a 16-bit address memory paging is needed if more than 64K of memory is to be addressed in a particular space. An external device needs to supply the upper addresses beyond the 16-bit memory range. This document describes how to implement this solution and give

Secure In-Field Firmware Updates for MSP MCUs
Texas InstrumentsIn-field firmware update is a feature that is increasingly used in microcontroller-based applications today and important benefits include service and support to products that are already deployed in the field (for example being able to correct bugs or add new functionalities). As common as in-field firmware updates are in embedded systems this feature is also commonly exploited by attackers; if
Voltage-Feedback Amps vs Current-Feedback Amps: Bandwidth and Distortion
Texas InstrumentsCurrent-feedback amplifiers have nearly constant bandwidth for varying closed-loop gains. The reason is that the user can adjust the open-loop gain of the current-feedback amplifier by changing the feedback network without affecting the open-loop pole.
