I am using the AD8542 in an application powered by a 3V coin cell. As such, the power for the AD8540 is turned on/off by a FET. What is a good number to wait after applying power to the AD8542 before it is ready for signals?
May you please provide any data of AD8541/AD8542/AD8544's voltage noise in low frequency? I mean 0.1-10 Hz uV p-p.
I want to use it for EEG/ECG amplifier: exactly AD8542 - one op-amp for getting reference voltage (Vmid)- for a voltage follower in…
I'm using AD8542 to create relaxation oscillator with the schematic below
But it has problem with temperature. Frequency out is drift about 4-5Hz/*C.
Can you help me to reduce this effect?
I get the following error when performing a simulation in ADS 2015.01 using an imported AD8542 SPICE model.
Error detected by hpeesofsim during netlist flattening. 'ad8542.s1' is an instance of an undefined model 'spice_vswitch'.
I think Matt is on to something, but the AD8567 is a quad. Look at the AD8542. It's a cheap dual that should get
within 20-30 mV of ground sinking 100 uA. See figure 22 on the AD8542 datasheet.
To limit the input voltage, I put 10k ohm series register and two diodes before the input of AD8542.Voltage at the input pin is limited between -0.7V and +5.7V.Does +5.7V input voltage cause damage to AD8542 which operates with Vs=+5.0V ?How about…
I would like to know how to decide the condition of "Large signal voltage gain".
For example, AD8542's condition is
RL=100Kohm Vo=0.5 to 2.2V
How to decide this vo condition…
In AD8542's D/S, DMAX is 97%. Would it be available both charge mode and discharge mode ? We consider DC in as +48V and DC out as +1.5V for battery. In this case the maximum duty would be 96.8% at discharge mode. How much is minimum on time at charge…
