Single-ended input to differential output conversion circuit reference design

TIPD131

Overview

This TI Precision Verified Design provides the principles, component selection, simulation, PCB design and measurement details for a single-ended input of a specific differential output circuit that converts a single-ended input from +0.1V to +2.4V ±2.3V differential output on a single +2.7V supply. The output range is specifically limited to maximize its linearity. This circuit consists of 2 amplifiers. An amplifier acts as a buffer, creating the voltage Vout+. The second amplifier inverts the input and increases the reference voltage to produce Vout-. Both Vout+ and Vout- range from 0.1V to 2.4V. The voltage difference Vdiff is the difference between Vout+ and Vout-. This will give a differential output voltage range of +2.3V.

characteristic

● 100kHz small signal bandwidth
● Low power consumption: 100mA current consumption
● ±0.1% FSR Vdiff uncalibrated error
● ±0.01% FSR Vdiff calibration error
● Convert 0.1V - 2.4V input to ±2.3V output at +1.25V Vcm

How to choose the value of external inductance when CD1366 is used for automatic gain
Our company has an analog descrambler that uses the CD1366 chip. When the analog signal strength is greater than or equal to 50DB, the test is normal and the descrambling effect can be achieved. Howev

Error when mounting the host root file system using nfs
After booting in u-boot, "Unable to get nfsd port number from sever, using default" appears. What's going on? setenv linux_arg root=/dev/nfs nfsroot=192.168.253.1:/armsys2440/root ip=192.168.253.9:192
Is the IRFP460 I bought a fake tube?
I've been playing around with amorphous inverters recently. I bought a pack of 460 tubes to try out for the backstage. Every time I put one on, it exploded. I was furious. I thought there was somethin
IAR Embedded Workbench licensing issues
I downloaded an IAR Embedded Workbench. When I just ran it, it said it needed something like a license. Is there a ready-made license? Please give me one~~~~~
