Part Number: LMP7721 Hi,
I'm designing a TIA circuit using LMP7721 TO detect 100p~500pA (or even smaller) current in some bio liquid.
Usually we will have a buffer to drive the reference voltage to the sheilding layer of a coaxial cable or the middle…
Part Number: LMP7721 Other Parts Discussed in Thread: LMP7715 I modified the components on the LMP7721 evaluation board as shown in the figure below to measure the voltage of an ion combination electrode. The voltage range is -0.5V to +0.5V. Due to the…
Part Number: LMP7721 Other Parts Discussed in Thread: MSP430F6736A Hello TI team,
I am using the LMP7721 as a transimpedance amplifier for low-current measurement in an electrochemical sensor readout system. The target current range is from pA to nA…
Part Number: LMP7721 Other Parts Discussed in Thread: LMP7715 , LMP91200 Hi everyone,
I am developing a dual-channel analog front-end (AFE) for pH and ORP electrochemical sensors using components from Texas Instruments. The expected output signal ranges…
Part Number: LMP7721 Dear TI Team,
GE Vernova is developing a fleet-hardened sensor system for industrial gas turbines. We are industrializing our signal conditioning chain and evaluating high-fidelity component solutions for sub-picoCoulomb charge…
Part Number: LMP7721 Tool/software: Electro-chemical oxygen sensor output connect to LMP7721, the output of LMP7721 is not right. (output is very high)
Connect a current source to LMP7721, the output of LMP7721 is right.
The output of electro-chemical…
Part Number: LMP7721 Tool/software: Hi,
I have a customer looking for a femtoampere amp similar to AD4530-1. Who would be the correct amplifier team applications engineer to loop into an email?
Best regards,

PADC Applications Engineer
Part Number: LMP7721MAEVALMF_NOPB Other Parts Discussed in Thread: LMP7721 , OPA392 , OPA397 We have purchased TI’s LMP7721 Multi-Function Evaluation Board. Without modifying the original board layout, I wired 5V to the V+ terminal and directly shorted…
Part Number: LMP7721 Tool/software: I have a trans-impedance circuit with 100M and 2G feedback. I was required to add a capacitor in a limited space. the value would be 1300pF (or 2700pf) and 560pF.
I usually select polystyrene, which has been popular…
