This document supplies information for using the Expansion Bus Module (EBM) on the TMS470R1B1M to interface to external memory and peripherals. The module supports the multiplexing of the input/output (I/O) functions and the expansion bus interface. When the I/O functions are not used the EBM can be used to interface 8- or 16-bit memories.

Low-Voltage Differential Signaling Yields Megatransfers per Second with Milliwatts of Power

RS-485 is a widely used standard for industrial communication due to its simplicity and suitability for use in high-noise environments on long cables. Inherent in the standard are balanced signal drivers and receivers which use differential signaling to reject common-mode noise. Receiver hysteresis is commonly used to ensure glitch-free reception even when differential noise is present. This appl

In TI’s line of high-speed analog-to-digital converters (ADCs) with SNRBoost technology output amplitude tends to deviate from its expected value when the applied input amplitude is small. This application note explains this phenomenon and the reasons it occurs.

In many applications, a key design goal is to minimize variations in power delivered to a load as the supply voltage varies. This application brief describes a simple DC brush motor control circuit us

How to Configure the bq20z80

This document describes issues of interest related to migration from the TMS320VC5409 to the TMS320VC5416. The objective of this document is to indicate differences between the two devices. Functions that are identical between the two devices are not included. For detailed information on the specific functions of either device refer to the following data sheets and reference guides: TMS320VC5409

In their effort to approximate the ideal op amp manufacturers must not only maximize the open-loop gainand minimize input-referred errors such as offset voltage bias current and noise but must also ensureadequate band-width and settling-time characteristics. Amplifier dynamics are particularly important inapplications like high-speed DAC buffers subranging ADCs S/H circuits ATE pin dr

This application report describes an echo canceller system using the Texas Instruments (TI?) TMS320C50 digital signal processor (DSP). The system is based on based on low resolution time-delay estimation using the knowledge that mainly one or two active regions (depending on the number of reflections in the communication channel) characterize the impulse response of a typical echo-path in telepho

The components of each demo board vary by device type and voltage option. Lists of materials are provided which specify the correct external components to be used with each TI part type.

The open-loop output impedance (Z_O) of an operational amplifier is one of the most important specifications. Proper understanding of Z_O over frequency is crucial for the understanding of loop gain bandwidth and stability analysis.This application note provides an in-depth understanding of the PGA900 Z_O magnitude over frequency. The effects of temperature power

This application report describes how to use LP3943/44 as a general-purpose input/output (GPIO)expander. It is recommended that circuit data sheets are read first and used in conjunction with thisdocument.

This application report describes the key elements and simple usage of the CC111xFx and CC251xFx Advanced Encryption Standard (AES) encryption and decryption coprocessor.

The main objective of the document is to explain the CC111xFx and CC251xFx software required to operate the AES coprocessor with and without DMA assistance.

A three phase sine wave oscillator can be built using one UAF42 state variable filter along with some resistors and diodes. Three output nodes are available; highpass out bandpass out and lowpass out. The signal at the bandpass and lowpass out nodes are 90° and 180° out of phase respectively with the highpass out node. An on-chip auxiliary op amp is available for use as a buffer or gain
