Why the designed analog signal sampling circuit will cause the LT1994 to overheat，Can you give me some help？
My customers are considering LT1994 and received questions about bandwidth.
<conditions>Input signal: ± 1 VGain: × 4
#1 What is the bandwidth at this time? Considering from GBP (70 MHz) when Vs = 3 V, Is it about 70 ÷ 4 = 17.5 MHz?
Error occurred "Analysis time step too small; time = 1.7562e-005, timestep = 1.25e-019; trouble with U5:swlim-instance s:u5:4" while doing transient analysis with LT1994 .Please guide me to sort out this issue.

Pin VOCM in LT1994 is not works, it is totally work in wrong way. please correct it. :'(((((((((( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'( :'(…
Apologies for the late reply.
I took a look at your snapshots and saw some LT1994 units had wrong orientation. This is likely the cause of the board not working as expected.
In parallel, we'll work on fixing the mask issues on the board to properly…
In LT1994 by 150 diff load and 3.3 single supply yo can see this:
At the right side of picture you see "power". It says 23.1mA into Vcc! and 18.8mA from Vee!
First OpAmp must sink current from Vcc not sourcing to it!!!! secound why these (from…
Hello, I have some questions regarding the low noise and high PSRR circuit design described in Application Note 159, AN159: Measuring 2nV/√Hz Noise and 120dB Supply Rejection on Linear Regulators.
I would like to build the circuit in figure 16 on…
