Part Number: LM1458 Other Parts Discussed in Thread: TLV9302 , LM324 Customer are designing in a DC power supply project. They used LM1458 device and power is -15V and +15V by LM7915 and LM7815.
They uses LM1458 to amplify the signal on the sampling…
Part Number: LM1458 Other Parts Discussed in Thread: TLV9002 , UA741 Hi,Will the LM1458 work properly at 80°C when the power consumption of the LM1458 does not exceed 0.1mW? (The supply Voltage are ±2.5V)
Part Number: LM1458 Hi All
can any one please provide me with the following for LM1458:
- max OUTPUT short circuit current limit for both sinking & sourcing conditions.
- supply current versus supply voltage curve.
thanks
Hello Thiago,
My research has shown that this is a custom device, and as such, information concerning this device can only be disclosed under NDA with the original customer.
The website that you referenced in your previous post indicated this was…
Hi Hong,
We saw Automatic Symmetry Correction in datasheet as below, we can't refer full datasheet and could you also provide the full datasheet to us? Besides, below is the customer (Uni-trend) schematic, please help to check how to configure the Automatic…
Hey Dan,
LM120K-5.0/883 is indeed obsolete. I've attached the PDN.
We don't have an exact P2P replacement so I'd recommend the UA79 series as the closest alternatives.

to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
