  • Composite Amplifiers &mdash AN21
    PDF, 330 Kb, Datei veröffentlicht: Jul 1, 1986
    Applications often require an amplifier that has extremely high performance in several areas. For example, high speed and DC precision are often needed. If a single device cannot simultaneously achieve the desired characteristics, a composite amplifier made up of two (or more) devices can be configured to do the job. AN21 shows examples of composite approaches in designs combining speed, precision, low noise and high power.

  • Component and Measurement Advances Ensure 16-Bit DAC Settling Time &mdash AN74
    PDF, 980 Kb, Datei veröffentlicht: Jul 1, 1998
    DAC DC specifications are relatively easy to verify. AC specifications require more sophisticated approaches to produce reliable information. In particular, the settling time of the DAC and its output amplifier is extraordinarily difficult to determine to 16-bit resolution. This application note presents methods for 16-bit DAC settling time measurement and compares results. Appendices discuss oscilloscope overdrive, frequency compensation, circuit and optimization techniques, layout, power stages and a historical perspective of precision DACs.
