Other Parts Discussed in Thread: LM7301 , LM7321 I recently tried to load the output of a circuit which was being driven by an LM7301 op-amp. The load was around 1K and the output was DC and adjustable from 0v to 4v. The input to the op-amp was a DAC output…
Hi Guys,
My LVT172 part arrived, and bellow are my findings.
The circuit is the simple textbook inverting amp I showed at the very beginning of this thread.
Note: I dropped the power supply rails from +/- 15V to +/-10V but still well within the range…
Other Parts Discussed in Thread: LM7301 , OPA209 Hi,
I am using an OPA209 to build a 2.5V voltage reference. I use two 10kohm resistors to divide the 5V supply voltage and send it to the non-inverting input of an OPA209. The inverting input is shorted…
Part Number: INA250-Q1 Other Parts Discussed in Thread: LM7301 , INA250 , INA301 , INA200 , INA139 , INA199 We are trying to design a device for detecting a specific and configurable current value threshold, capable to generate a interruption in our MCU and…
Hi Matt, I know you aren't in charge of amplifiers but I would like to understand completely how to choose correctly the op amp in any type of application and I have a small doubt. For exmaple in the op amp LM7301 the datasheet doesn't metion the…
Deepak,
I see two problems.
1) The LM339 common mode range does not include VCC+ 2) The comparators need an offset of about 15mV added. So 0mV input is off and 30mV is on.
High voltage (>6V) comparators with rail to rail (or VCC+) common mode range…
