Other Parts Discussed in Thread: INA321 Hi,
I am currently using an INA321 Instrumentation amplifier with a Metallux CPS 1010 16Bar Pressure Sensor. However, I am struggling with a drift situation where the voltage I am receiving from the INA321 tends…
Hi Venkata,
You do not specify whether you power both IC's from a single 5V power supply or use separate supplies (V1 and V2 show on your schematic). But even if you use a single supplies, IC's power-up time may be different - in the case of V2…
Part Number: INA819 Other Parts Discussed in Thread: INA321 Hi Team,
Our customer is looking for a precision amplifier for invasive blood pressure monitor. He is considering instrumentation amplifiers INA819 and INA321. Can you confirm which one is more…
David,
Your scheme of shutting down the resistive bridge and op amp with a FET switch MAY work BUT you must take into account the Roff resistance of the switch (it's not infinite). Since the shutdown is accomplished by the voltage drop across the switch…
Yunsik,
Adding INA321 increases the gain by G = 5+5*(10k/10k) = 10 but adds cost and increases board room - see below.
Thus, with INA321 the total transimpedance gain becomes 10*10Mohm = 100Mohm - see below. However, now Iout is significant and will…
Other Parts Discussed in Thread: INA321 The data sheet for the ina321 says that it turns on in microseconds from shutdown. Is there a spec for the turn on time or has it been measured?
Other Parts Discussed in Thread: INA321 I am trying to make a simple ECG amplifier using INA 321 and OPA 336. I am driving this amplifier using a an ECG simulator(http://www.heinstruments.com/ecg-simulator.htm), hence I do not have a right leg drive circuit…
Part Number: INA122 Other Parts Discussed in Thread: INA350 , , INA321 , INA155 Hello,
What is the best in stock cross you'd suggest for the INA122U? Would you be able to confirm the difference between INA155U vs INA155UA?
Thanks, Adam
Other Parts Discussed in Thread: INA321 Hi,
first post so forgive me any lapses in etiquette!
I see in the datasheet for the INA321that pulling the shutdown pin to 0V puts the device into shutdown mode and that the output impedance then goes high and therefore…
