## 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. ...

## 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 ...
