A fully differential amplifi er is often used to converta single-ended signal to a differential signal, a designwhich requires three signifi cant considerations: theimpedance of the single-ended source must match thesingle-ended impedance of the differential amplifi er,the amplifi er’s inputs must remain within the commonmode voltage limits and the input signal must be levelshifted to a signal that is centered at the desired outputcommon mode voltage.

Recent advances in low voltage silicon germaniumand BiCMOS processes have allowed the design andproduction of very high speed amplifi ers. Because theprocesses are low voltage, most of the amplifi er designshave incorporated differential inputs and outputs to regainand maximize total output signal swing. Since many lowvoltageapplications are single-ended, the questions arise,“How can I use a differential I/O amplifi er in a single-endedapplication?” and “What are the implications of suchuse?” This Design Note addresses some of the practicalimplications and demonstrates specifi c single-endedapplications using the 3GHz gain-bandwidth LTC6406differential I/O amplifi er.

Many 8-bit and 16-bit microcontrollers feature 10-bitinternal ADCs. A few include 12-bit ADCs, but these oftenhave poor or nonexistent AC specifi cations, and certainlylack the performance to meet the needs of an increasingnumber of applications. The LTC®2366 and its slowerspeed versions offer a high performance alternative, asshown in the AC specifi cations in Table 1. Compare theseguaranteed specifi cations with the ADC built into yourcurrent microcontroller.

Linear Technology’s High Frequency Product lineupincludes a variety of RF I/Q modulators. The purpose ofthis application note is to illustrate the circuits requiredto interface these modulators with several popular D/Aconverters. Such circuits typically are required to maximizethe voltage transfer from the DAC to the baseband inputsof the modulator, as well as provide some reconstructionfi ltering.

This application note is an overview discussion of theLinear Technology SPICE macromodel library. It assumeslittle if any prior knowledge of this software library or itshistory. However, it does assume familiarity with both theanalog simulation program SPICE (or one of its manyderivatives), and modern day op amps, including bipolar,JFET, and MOSFET amplifier technologies

This publication represents the largest LTC commitmentto an application note to date. No other application noteabsorbed as much effort, took so long or cost so much.This level of activity is justified by our belief that high speedmonolithic amplifiers greatly interest users.
