Picking ESD Diodes for Ultra High-Speed Data Lines
Texas InstrumentsThis application report addresses three key criteria for selecting an ESD device for protecting high-speed signals. As the industry continues to trend towards smaller chipset features sizes to address higher speed data rates, tolerance of transient voltages has continued to shrink as well. Picking the right ESD device the first time is critical to preventing costly board re-spins during EMC testing. By using the three techniques discussed in this paper, device selection can be greatly simplified and streamlined.
AB-170: Ultrasound Processor Supplementary Material
Texas InstrumentsAn ultrasound system employs a multichannel phased array of acoustic elements to form an image. Previous implementation of this function has used bipolar technology. 0.5u CMOS technology has the advantage of lowering the cost and increasing functionality compared to using bipolar technology.

Automatic Gain Control (AGC) Using the Diamond Transistor OPA660
Texas InstrumentsMultiplication of analog signals has long been one of the most important nonlinear functions of analog circuit technology. Many signal sources however such as CCD sensors pin diodes or antennas deliver weak oscillating and simultaneously wide-band signals. But now a new multiplication method is available. Used as a wide-bandwidth Automatic Gain Control (AGC) application circuit the integra

General Guide to Implement Logarithmic and Exponential Operations on Fixed-Point
Texas InstrumentsModern audio and video compression algorithms usually take the advantage of logarithmic characteristics of human ears and eyes. This approach greatly reduces the redundancy in signals being processed. However it poses a requirement on fixed-point DSPs to handle these logarithmic and exponential operations.This application report provides a general guide to implement these operations on fixed-
Low Power Input and Reference Driver Circuit for ADS8318 and ADS8319
Texas InstrumentsThe one size fits all approach to operational amplifiers is not effective. Every application has its own specific requirements that must be fulfilled. Appropriate selection of the op amp that drives an analog-to-digital converter (ADC) in a low-power application is a critical step. Most available low-power op amps trade off low-power features with other parameters such as bandwidth settling t
