Part Number: LMC6464 Other Parts Discussed in Thread: TLC3702 Tool/software: 1, not sine wave at output, severe disortion.
2, poor bandpass with big attenuation.
3, orignial schematics (the circuit in the blue circle is said to be a MBPF (bandpass…
Hello Shekhar,
I suggest a quad, ultra-low input current op amp such as the LMC6464 or LMC6064. Their input bias current should not load the gas sensor and the supply current is very low so little heat should be generated.

Hi Marceli,
the output current of XTR111 must be limited to less than 50mA or you risk that the XTR111 becomes damaged. The XTR111 is not designed to output a current of 100mA.
I would think about using the improved Howland current pump:

Part Number: OPA547 Other Parts Discussed in Thread: TINA-TI Team,
We are using the OPA547 for an "improved Howland current pump" to turn voltage to a 0–20 mA output.
It works ok until a given input voltage level. When this input voltage is reached…
Hi Faisal,
A complete discussion of the Improved Howland Current Pump is covered in TI Application Report, SNOA474 (AN-1515), A Comprehensive Study of the Howland Current Pump. That should answer most any question you may have about the fundamentals…
to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
