Part Number: LF398-N Tool/software: Hello E2E Support Forums!
This is my first time posting, let me know how to best utilize these forums.
In my design, I am using the LF398H/NOPB (same Datasheet as the LF398-N described above) as a sample and hold amplifier…
Part Number: LF398-N Other Parts Discussed in Thread: OPA192 Hi Team,
In our existing Design AD582KD (Sample and Hold amplifier) is used. With TI suggestion, In new design we are using LF398-n. During Bench level testing we noted that, In hold mode…
Part Number: LF398-N Hi Team,
I have AD582 in my board. I want to replace it with LF398-N. Pls let me know how to modify the LOGIC and LOGIC REFERENCE signals connection.
Existing circuit with AD582 is shown below.

Hi Srikanth
Srikanth Kacchu1 said: Does this difference in input voltage range create any issue? Power supplies in my design are +/-15V.
If you look at the AD582, the datasheet is specified at +/-15V, and "up to +/-12V" is the part's Vcm range. "up to…
Part Number: LF398-N Hi Team,
Good day. I was looking for an IBIS/Spice model for LF398-N. I found this thread made five years ago ( https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/716981/lf398-n-tina-ti-model ) I want to confirm…
Part Number: LF398-N Hello,
I have a question for LF398-N.
The datasheet specifies the power supply range as +-5V to +-18V.
Is asymmetric supply range like -5V to +31V also acceptable if (V+) – (V-) is less than 36V?
Regards, Oba
Part Number: LF398-N Hello,
I am planning to use LF398-N sample and hold amplifier with a microcontroller with the following logic levels.
It's written in the data sheet of LF398-N that it's differential logic threshold is 0.8 min 1.4 typical and 2…
Part Number: LF398-N Hello i have few questions regarding LF398AN/NOPB ,
1) If I am not planning to use the offset trimming feature can I leave it floating or should it be tied somewhere?
2) I am planning to use an analog multiplexer before the LF398AN…
Part Number: LF398-N Hi Support Team.
I am creating a delivery specification for TSC2046EIPWR
In the Qualification Summary, the results of ESD-HBM and CDM are described as "See data sheet". However, the datasheet does not show the results of…
Part Number: LF398-N Dear Members,
I have generic questions and expecting the answers.
1. Why does not TI has Sample and Hold Amplifiers? They have one from NSC folio, LF398 without a hold capacitor.
2. From other Vendors, AD and Renesas (Intersil) have…
