With the introduction of the MPY634 multipliers wideband analog multiplication need no longer be a multicap affair or imply performance compromises. Along with its 10MHz small-signal bandwidth the four-quadrant chip has a laser-trimmed DC accuracy of 0.25% and adjustable scale factor and the ability to drive loads down to 2kΩ.

The Fast Fourier Transform (FFT) is an efficient means for computing the Discrete Fourier Transform (DFT). It is one of the most widely used computational elements in Digital Signal Processing (DSP) a

Viterbi Coprocessor (VCP) is a programmable peripheral for decoding of convolutional codes integrated into Texas Instruments' TMS320C6416 DSP device. The VCP is controlled via memory mapped control registers and data buffers. Control registers can be accessed directly by the CPU whereas data buffers are typically accessed using the EDMA controller. This application note describes the relationshi

Classical op amps such as the OPA627 have excellent performance in applications where the required gain bandwidth is low compared to the gain-bandwidth product of the op amp. However increasing closed-loop gain decreases the error-reducing loop gain. Furthermore starting at relatively low frequencies the loop gain rolls-off at 20dB/decade of signal frequency increase. In combination these effec

This document details the voltage, current, and sequencing requirements for the i.MX31 and shows how to power it using the TPS650240.

The low dropout (LDO) voltage regulator brings the advantage of power savings to system design byreducing the voltage required to maintain output regulation. However the traditional LDO has alwaysbrought with it the disadvantage of placing tight restrictions on the equivalent series resistance (ESR) ofthe output capacitor in order to keep the regulator stable. This requirement has been elim

Though low power consumption is a feature of CMOS devices sometimes this feature does not meet a designer?s system power supply constraints. Therefore a partial system power down or multiple Vcc supplies are used to meet the needs of the system. This document shows electrostatic discharge protection circuits. It also provides circuit and bus driver examples of partial system power down and curren

This application note describes the implementation of multichannel echo control on a TMS320C62xx processor core that can cancel echoes with a 4-32-ms delay. This software is based on the leaky normalized least mean square (LMS) filter with either 16- or 32-bit weighting coefficients.

How to Implement SHA-1/HMAC Authentication for bq26100

Design of a power supply for a high-performance point-of-load processor requires special attention to manage core and input/output (I/O) voltage sequencing which is critical to device operation and long term reliability. The TPS54x80 devices of low input voltage synchronous-buck dc/dc converters are designed for easily implementing sequential ratio-metric or simultaneous sequencing schemes. F

The bq34z100-G1 device is configurable to provide gauging for Li-Ion Li-Polymer LiFePO4 lead acid (PbA) NiMH and NiCd cell chemistries. The gauge can support charge and discharge currents up to 32 A pack capacities up to 29 Ah and pack voltages up to 65 V without special setups. This document provides information to setup the gauge to support packs that exceed these current capacity or vol

This application note describes an approach to design feedback loop compensation for an LLC resonant half-bridge power converter. The approach described here is based on the measured Bode plots of the modulator generated by a network analyzer. Frequency domain poles and zeros in the feedback loop compensation can be analytically determined then fine-tuned with a bench test. This measurement is ne

As new generations of microcontrollers lower their supply voltages from 5 V to 3.3 V and beyond issues with interfacing and noise are increasing. This application report presents cost-effective interfacing techniques for inputs and outputs of 3.3 V microprocessors in an automotive environment. In addition concerns about 3.3 V analog-to-digital converters (ADC) are discussed.
