## DC266B-B - LTC1562CG-2 | Very-Low-Noise, Low Distortion Quad Universal Filter

Sep 23rd 2016

Demonstration circuit DC266B-A is for the evaluation of 8th order filter circuits using an LTC1562 (no dash) and DC266B-B for an LTC1562-2. LTC1562 and LTC1562-2 are quad 2nd order active-RC filter building blocks. Each 2nd order section has an integrator trimmed with internal capacitors and resistors to 100kHz and 200 kHz for ...

## Audio Spectrum Analyzer with the Linduino

Apr 12th 2016

There are several methods for implementing a spectrum analyzer. I’ve been working with SAR ADC products for some time, and using the Fast Fourier Transform (FFT) for spectral analysis on a daily basis. Another common method for implementing a spectrum analyzer is called the swept-tuned receiver. This method involves mixing ...

## DC675B - LT1568CGN Demo Board | Active Filter Building Block IC Configured as 4th Order 500kHz Bandpass

Apr 13th 2015

Demonstration circuit DC675B is for the evaluation of filter circuits using an LT®1568. The LT1568 is a dual 2nd order active-RC filter building block with precision ±0.75% capacitors and low noise op amps with 180MHz GBW trimmed to ±10% maximum variation. The ±10% GBW variation of the LT1568 op amps ...

## LT1567 A Single-Ended Input to Differential Output Amplifier

Oct 8th 2001

This circuit shows a circuit for generating a differential signal from a single-ended input. The differential output noise is a function of the noise of the amplifiers, the noise of resistors R1 and R2 and the noise bandwidth. For example, if R1 and R2 are each 200W, the differential output voltage noise density is 9.5 nV/ÖHz ...

## LT1567 A Differential Input-to-Single-Ended Output Amplifier

Oct 8th 2001

This circuit shows a circuit for converting a differential input to a single-ended output. For a gain equal to one (R1 = R2 = 604W and VOUT = V2 – V1) the input referred differential voltage noise density is 9nV/rtHz and differential input signal-to-noise ratio is 80.9dB with 0.2VRMS input signal in a 4MHz noise bandwidth. ...
