Part Number: TLV8544 Hi TI experts,
I am designing pir circuit with bluetooth low energy. I use TLV8544 to amplify the signal from the pir and bluetooth ic will receive the signal for processing.
it is my schematic for my project.
and Bluetooth chip…
Part Number: TLV8544 Other Parts Discussed in Thread: , TINA-TI Hi TI experts,
I'm working on PIR sensor project and I'm trying to figure out where to lower the noise on the 2nd stage output of op-amp. Below is the waveform of my circuit design, the yellow…
Part Number: TLV8544 Why the values in the stage 1 is not the same that the stage 2 ? I try to reduce the cost. Why C33 is not 3.3uF like C36 ? Same F, Same G
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…
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…
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?
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…
