Part Number: DAC7578 I am trying to calculate the output Voltage range for input voltage range of 0 to 3.3V using DAC 7578 where Vref =3.3V and AVdd = 3.3V. Is their any formula that I can use to calculate the range? or can I use Analog engineer's calculator…
Part Number: INA333 Other Parts Discussed in Thread: TINA-TI Hello, When using the INA Vcm vs Vout calculator from the Analog Engineer's Calculator, the INA333 model only gets to within 0.3V of the supply rails. For example, with a Vs- of -2.5 and Vs…
Hi Shoo,
I am going to close this inquiry for now. If you have other questions, please let me know.
Below is the Analog Engineer Calculator that you may use to check the linear operating point of an instrumentation amplifier.

Hi Taku-san,
The INA823 is one possibility available on the SOIC, pin compatible with the device you list above.
The device is specified over the extended temperature range -40C to +125C (but not above +125C).
Regarding the instrumentation amplifier linear…
Hey Randall,
What is your common mode voltage set to?
We have a free to download Analog Engineers Calculator (link below) that can help assist in finding the input and output ranges and linear operating range. This can be used in parallel with Tina Ti…
Hey Roman,
Using our Analog Engineers Calculator (link below), I am seeing that with the conditions you have outlined the max differential input is +/-1 V. The max output is 3.5 V and 1.5 V. Operating outside of these conditions will give non-linear results…
Hey Preetham,
Using an INA device on a single supply and common mode near ground can be challenging. It is a balancing act between the common mode voltage and the reference voltage. To help aid in the discussion we have an Engineers Calculator (link below…
Hello,
Additional to Jacob's response, I recommend utilizing the analog engineer's calculator that shows you how the output is affected by the common mode:

Hi BongJo,
The INA331 is configured internally for a minimum gain of 5 V/V. This means that for an output swing of +/- 1V, the voltage generated by your input current across the 300Ω shunt resistor must be +/-200mV or less. For a 300Ω shunt resistor,…
Hi Bowen,
Thank you for the additional information. Which ADC the customer is using?
Depending on the ADC and configuration, there is a minimum gain bandwidth that is required from the driving op amp. You can also use the Analog Engineer's Calculator…
