Hello Avi,
The LMP7721 has a robust output stage and is capable of sinking/sourcing at least 10 mA, and likely more as the datasheet Figures 32 through 37 show. Therefore, adding the ADS1118 very high input impedance to the LMP7721 output should not…
Part Number: LMP7721 Hi,
Could you please tell me the silk regulation of LMP7721? What does the 788C on the mask mean? Please refer to the below picture.
Thanks.

Part Number: LMP7721 Hello,
Currently, I'm design a transimpedance amplifier using the LMP7721 and I look after the input impedance (ohm and fF) of this amplifier, but no way to find these values in the datasheet.
Would it be possible to you to provide…

Hello,
I am using LMP7721 in three electrode potentiostat (homemade) as a voltage follower.
I have tested the same but getting negative voltage output.
I have…
Hi Zak,
Thanks for your information.
I checked the input capacitance of TLV333 in the datasheet, sorry because I didn't see it in the first time. Also It's possible to fine the output resistance 2kOhms.
I've found the e2e thread that talk about…

Please refer to schematics Attached:- Circuit Portion 1
1)IS1OUT- Output from Nanosensor Which is in the range of 0nA to 10uA
2) U6 Output…
Part Number: LMP7721 Hi Team,
The customer is using LMP7721. The attachment is his schematic. R10 is 10M. R9 and R11 is 0 ohm. C18 is unconnected.
The APD device can provide the current for LMP7721. The IN- pin input current that the APD device provides…
Part Number: LMP7721 Hi,
LMP7721 GBW is typical 17MHz but what value I should you when I make the worst case analysis?
In some document (another manufacturer) was mentioned that only 60% of typical GBW value should use.

Part Number: LMP7721 Other Parts Discussed in Thread: LM35 , ADS1115 Hello, On EasyEDA software I have BNC connector with Output and GND pads, on sample I see "pH Bias", Does this go on BNC Connector GND pad. Kinda confused since I see other circuits…
Part Number: LMP7721 Other Parts Discussed in Thread: LM7705 , LMC6442 Hi,
I've been building a potentiostat for my electrochemical sensor (in water) based on AN-1798 and below is the schematic of my circuit.
The circuit is petty much the same…
