Part Number: TLV8544 Hello, I would like to design a circuit that outputs a logic low/high depending on the direction the object is traveling. The inputs would be from a PIR sensors since I am trying to detect human direction in realitvely close proximity…
Part Number: TLV8544 Hello Team,
There are questions regarding TLV8544 EMIRR performance. Could you help provide comments?
1. In TLV8544 datasheet Figure 25 EMIRR performance, is the measurement done by injecting noise at input pin via conduction method…
Part Number: TLV8544 Hello Team,
In TLV854x datasheet, the input impedance in page 6 shows differential and common mode are 2pF and 4pF respectively. Could you help add input differential and common mode resistance? Although TLV854x is a CMOS op amp which…
Part Number: TLV8544 Input is an IR Photodiode, receiving reflected pulses. 1st stage is a transimpedance - diode to ground,3meg feedback resistor. I would like to AC couple the next stage to try to ignore the ambient light signal. Any suggestions?
Hello Chuck,
Sorry for the really long reply. I could not shield the breadboard (it did not work actually, 50hz noise was still there) so I decided to print the circuit. I just had enough time to print the PCB. I made two PCBs (for XLitas LHI 968 and…
Other Parts Discussed in Thread: TLV8544 I used your design parameter of TLV8544 for PIR application to simulate circuit as your reference design. however, the result of simulation is not good. the signal of pir cannot be amplified, the gain is just -300db…
Hi Rogier,
there are several options you can try:
1. Remove C9.
2. Heavily increase C14.
3. Add an isolation resistor of 10...47k in series to the output of U5.
What is supplying the TLV522? A Coin cell?
Does it work when you completely remove the ADC…
