Part Number: LM7705 Hello,
LM7705 is a very commonly recommended device with op amps to get true swing to 0V on the output. I was looking for an equivalent automotive device and didn't see one. Is there a good similar or equivalent device to the LM7705…
Part Number: LM7705 Other Parts Discussed in Thread: LM27761
Team,
LM7705 can only source 26mA @ -0.232V.
-Do we have some comparable ICs that can generate the same negative voltage but with higher current? Newer IC like LM27761 do not seem to support…
Part Number: LM7705 Hi, we are using the LM7705 in one of our applications board to generate a negative voltage. We noticed that Vout increases with load. Here is what we get.
0mA Load: Vout = -0.238V 1mA Load: Vout = -0.528V 10mA Load: Vout = -0.682V 20mA…
Part Number: LM7705 Other Parts Discussed in Thread: OPA2991 Hello Everyone I want to know how much current can be handled by a single LM7705 device. I also wanted to know how many OPA2991 op-amps can be connected to a single LM7705. Thank you
The ADC input can be modelled as an R-C circuit (see section 8.3.1 of the ADS7028 datasheet). The TLV9304 will be able to drive it, but to ensure that the output can go to 0 V even if there is an offset voltage, and to move the output into the linear…
Part Number: LM7705 When there is no load, a negative voltage is output after a positive voltage is output. When a load (-7mA) was attached to the output, the positive voltage was not output and became a negative voltage.
Does the output voltage of the…
Other graphs do not exist. At 3.5 V, the drive strength will be lower.
What is the desired load? How much less is "less than 5 V"?
For a noticeable load (more than a few µA) at voltages near GND, consider adding the LM7705.
Input to OPA192 is 0-2V, so never negative.
If not something strange happens during startup...
No shorts. Sometimes the OPA have been working for hours and through multiple startups.
Will have a look at the LM7705.
Thanks..
