Extending the Resolution of the LTC2758

Noe Quintero - Application Engineer Mar 21st 2017
Introduction One of my favorite DACs is the LTC2758. It has excellent temperature stability and, when paired with a stable reference such as the LM399 or the LTZ1000, is an excellent choice for instrumentation applications. In this post I will present two methods for increasing the resolution of the LTC2758. The Search for ...

Uncompromised Clocking Solution for 16-Bit 2.5Gsps High Performance DAC

Clarence Mayott - Applications Engineer Sep 6th 2016
Design Note 555: Introduction The LTC®2000 16-bit 2.5Gsps DAC offers excellent AC performance. For many DAC applications, phase noise, noise spectral density (NSD), and spurious free dynamic range (SFDR) are critical to maximize the number of possible channels in a band without eroding the signal to noise ratio (SNR) in ...

DC2191A Upconverts the Output of the LTC2000

Doug Stuetzle - Senior Analog Applications Engineer Jul 19th 2016
The DC2191A is a new demo board that provides an LTC5579 upconverting mixer at the output of the high speed LTC2000 DAC.  The IF output of the DAC feeds a passive lowpass reconstruction filter which then drives the IF input of the upconverting mixer.  This interface is simple and requires no DC level shifting.   An ...

Common Questions About the LTC2668 Family of 16bit VOUT DACs

Mark Thoren - Staff Scientist
Chad Steward - Design Manager
Noe Quintero - Application Engineer
Apr 19th 2016
The LTC2668-16 packs 16, 16-bit high performance Digital to Analog converters (DACs) into a tiny, 6x6mm QFN package, with 8 and 4 channel versions in a 5x5 QFN, and 12-bit versions for lower resolution applications. A general purpose DAC such as this finds its way into a myriad of diverse applications, and tends to generate ...

Sep 1st 2015
There was a window of time in the 1950s and early ’60s when negative voltage rails were commonplace, when germanium PNP transistors were prevalent—like those used in an old “transistor radio”, now worth a fortune on Ebay. Nowadays, NPN transistors are more prevalent, since they basically work ...

Accurate, Fast Settling Analog Voltages from Digital PWM Signals

Mark Thoren - Staff Scientist
Chad Steward - Design Manager
Mar 17th 2015
Introduction Pulse width modulation (PWM) is a common technique for generating analog voltages from a digital device such as a microcontroller or FPGA. Most microcontrollers have dedicated PWM generation peripherals built in, and it only takes a few lines of RTL code to generate a PWM signal from an FPGA. This is a simple, ...
