Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: LM293 Tool/software: Hi Team,
Description: I am using the LM293 comparator as part of a two-stage digital input circuit. Each input stage consists of a separate comparator and is intended to function independently. The outputs of the comparators…
Part Number: LM293 Hi TI Team，
According to the feedback from TI CQE, the LM293DGKR process has been changed, and the screen printing on the chip surface has also been changed. The following customer applied two batches of different incoming materials…
Part Number: LM293
Here's the example as shown.
1. is 5V for comparator Vcc sutible application because of postage input range is 0~3V even first stage of OPA is 24V?
2. If Comparator Vcc should be 24V. does rail to rail input for Comparator is necessary…
Part Number: LM293 Other Parts Discussed in Thread: LM339 , LMV321 Hi team,
I built a circuit as below.
When I power on the circuit, Vin(5V power supply) rises immediately. Due to the pull up of R1, Vo(pin 4) and V+(pin 5) should be the same as Vin. V…
Hello Lumina,
The "CHN" is the new die, which will have performance closer to the LM393B.
The new die will meet LM293 datasheet specifications, and should perform the same, or better, when used within the datasheet parameters.
The different…
Part Number: LM2903B Other Parts Discussed in Thread: LM2903 , LM339 Hello,
I am doing the simulation in LTspice. With the same circuit, I see something wrong with the output of LM2903B. May I ask for some help? Either my circuit is wrong or the model…
Part Number: LM293 I saw someone use one series RC cross positive input and output of LM293. Usually, it composes an integral circuit if RC is cross the negative input and output of one OPA. However, I do not know why the similar circuit is used in comparator…
Part Number: LM293 Other Parts Discussed in Thread: LM339 Hi team,
My customer is using LM293, in their PCB they are leaving VOUT2 floating. But in the factory fabricate, sometimes the VOUT2 may be shorted to VCC due to improper soldering. Is there potential…
Part Number: LM193 Other Parts Discussed in Thread: LM393 , LM293 , LM139 , LM339 Hi team
Question 1: Refer datasheet SLCS005Z –OCTOBER 1979–REVISED OCTOBER 2017. Table 6.6. Electrical Characteristics for LM193, LM293, and LM393 (without A suffix…
