Part Number: THS3121 Other Parts Discussed in Thread: OPA2677 , , TINA-TI , OPA2675 Tool/software: Hello,
a while ago I discussed a driver for a small thermoelectric cooler ("TEC" or peltier element). The circuit was based on two inverting current-feedback…
Part Number: THS3121 Dear Sirs,
I found a big difference in frequency response between the circuit simulated on TINA (I attach the schematic and AC analysis) and the measurements in the real circuit.
In real circuit, after the flat band of 1MHz, there…
Part Number: THS3121 Other Parts Discussed in Thread: THS3061 , OPA691 , OPA690 , THS3215 , THS3491
Hi TI expert, I use TI’s high speed op amps to generate voltage within -12V and +16V. The circuit is simple and is as follows, where op1, op2 are THS3061 and…
Part Number: THS3121 Other Parts Discussed in Thread: THS3491 I'm trying to verify whether or not there is internal short circuit protection on the output of this opamp. We're using it for a pulse per second (20us PW) but there are requirements for short…
Part Number: THS3121
Dear TI expert,
I have a little doubt about THS3121's differential input voltage in absolute maximum ratings, which is +-4V given in its datasheet, http://www.ti.com/cn/lit/ds/symlink/ths3121.pdf
I just use 3121 with noninverting…
Part Number: THS3121 Could anyone tell me if the THS3121 opamp can be used in unity gain (non-inverting) mode?
In my application it oscillates; not due to layout problems.
I don't need the high freq. response of this power op amp, but the built-in high…
Part Number: THS3121 Hi All, can anyone please confirm if the opamp THS3121ID has any input protection diodes from positive & negative inputs to the supplies or any anti parallel diodes in between the input pins?
Other Parts Discussed in Thread: THS3121 Hi Team, My customer considers to use THS3121 for his application. He wants to get the graph "OUTPUT VOLTAGE vs LOAD RESISTANCE" under VS=±5V. *Figure 19 is under VS=±15V. Do you have the data …
Hello Jonah,
I will ask around, but I have not yet found any data on my end characterizing the parts mentioned (THS3120 & THS3121).
If you have any other questions for me to look into, please continue asking away .
Best,
Alec
Hi Seema,
do you connect a cable to the output of THS3121? In this case R138 should be identical to the cable impedance, otherwise distortion due to echoing can take place. If you connect a 75R cable to the output of THS3121, for instance, then R138 must…
