This application note discusses the UCC3884 frequency foldback peak-current-mode controller. The UCC3884 solves the current-tail problem often seen in high-frequency converters under overload fault conditions. Intended primarily for single-ended converters other features such as a maximum duty-cycle clamp and an accurate volt-second clamp are also included. The block diagram and the main features

The availability of detailed noise spectral density characteristics for the OPA111 amplifier allows an accurate noise error analysis in a variety of different circuit configurations. The fact that the spectral characteristics are guaranteed maximums allows absolute noise errors to be truly bounded.

This design note explains the differences between voltage-mode and current-mode switching power supply topologies. It includes a circuit diagram for each mode and suggests criteria for choosing which mode to use.

As the module is designed to support both Launchpad™ and SmartRF™ Studio platforms configure the board by changing the on-board jumper positions according to your application.

The Texas Instruments (TI) SN54/74LS123 dual retriggerable monostable multivibrator is a one-shot device capable of verylong output pulses and up to 100% duty cycle. The ?LS123 also features dc triggering from gated low-level active A andhigh-level active B inputs and provides a clear input that terminates the output pulse of any predetermined time independentof timing components R ext and

This application report describes how you can begin development now for the Texas Instruments TMS320C6712 digital signal processor (DSP) systems. The similarities and differences between the C6712 and the C6711 devices are briefly discussed. Because of the compatibility between TMS320C6000 generation devices existing C6000 software tools and development platforms can be used to develop code for t

This application note describes a method for improving the absolute accuracy of the 12-bit analog-to-digital converter (ADC) found on the F2810/F2811/F2812 devices. Due to inherent gain and offset err

Adaptive antenna arrays are expected to play a key role in meeting the demands of the wireless communication systems of the future. This application report focuses on the implementation of a DSP based three-element adaptive antenna array for narrowband wireless communications.

Extremely high-speed ADCs (>1 GSPS) demand a low-jitter sample clock in order to preserve signal-tonoiseratio (SNR). These 8- and 10-bit converters have best-case noise floors set by quantization noise.For an N-bit ADC sampling a full-scale sinusoid the well known expression for SNR (in dB) is: SNR =6.02N + 1.76. This sets the best case noise floor for an 8-bit ADC at −49.9 dBc. The noise f

This application report presents a method for interfacing the DAC8803 - a four-channel, current output, 14-bit multiplying digital-to-analog converter - to the MSP430F449 processor using the HPA449 fr

This application report discusses the use of the LMP90100/LMP90098 (24 bit) and LMP90080/LMP90078 (16 bit) sensor analog front ends (AFE?s) together with a resistive temperature device (RTD) using a 4

The application report Voltage Feedback Versus Current Feedback Op Amps SLVA051 outlines the basic operation of a current feedback operational amplifier (op amp) in relation to a voltage feedback op amp. One of the basic principles of a current feedback op amp is that its transfer function is a transimpedance equal to the output voltage divided by the current from the negative input terminal i.e.

In most customer applications a high level of decoding bit error rate (BER) performance is required. Since Convolutional codes and Turbo codes are widely used in wireless communication systems TI DSPs integrate two high-performance embedded coprocessors (enhanced Viterbi decoder coprocessor and enhanced Turbo decoder coprocessor) that significantly speed up channel-decoding operations on-chip.
