  • AB-174: Getting the Full Potential from your ADC (Rev. A)
    PDF, 72 Kb, Revisión: A, Archivo publicado: jun 28, 2002
    Many of today?s high-resolution ADCs (Analog-to-Digital Converters) are operating from a single supply and use fully differential inputs. This can be a problem for single-ended signals that are bipolar relative to common. This article illustrates circuit configurations that preserve the full-scale input range by using modern features, such as Programmable Gain Amplifiers (PGAs) and internal voltag

    PDF, 261 Kb, Archivo publicado: jun 11, 2001
    This application report presents a collection of analog circuits that may be useful in electro-optic applications such as optical networking. The circuits are Avalanche Photodiode Bias Supply 1; Linear TEC Driver-1, -2, and -3; Laser Diode Driver-1 and -2; and Temperature Under- and Over-range Sensing with a Window Comparator.

    PDF, 44 Kb, Archivo publicado: oct 2, 2000
    Have you ever had the experience of designing an analog gain block with an amplifier that is specified to be unity gain stable only to find that it is oscillating out of control in your circuit? Or have you ever replaced a stable voltage feedback amplifier with a current feedback amplifier to find that the current feedback amplifier immediately oscillates when placed in the amplifier socket? Oscil

    PDF, 187 Kb, Archivo publicado: sept 2, 2010
    Numerical Protection Relays (NPRs) are critical elements in any power distribution network. Generally, there are several different types of NPRs. Each type, however, shares a similar architecture, thus enabling designers to build an entire system solution that is based on a relatively small number of flexible components. This application note demonstrates how an NPR can be implemented using TI's e
  • Single-Supply Operation of Operational Amplifiers
    PDF, 77 Kb, Archivo publicado: oct 2, 2000
    Operation of op amps from single supply voltages is useful when negative supply voltages are not available. Furthermore, certain applications using high voltage and high current op amps can derive important benefits from single supply operation.
  • Op Amp Performance Analysis
    PDF, 76 Kb, Archivo publicado: oct 2, 2000
    This bulletin reflects the analysis power gained through knowledge of an op amp circuit's feedback factor. Feedback dictates the performance of an op amp both in function and in quality. The major specifications of the amplifier descibe an open-loop device awaiting feedback direction of the end circuit's function. Just how well the amplifier performs the function reflects through the feedback inte
