Part Number: TLV6741 Tool/software: Hi,
We built a mic pre-amp for electret microphone as following:
The power supply of 4.6V is from LDO, which is from TI, too. We measured the power ripple, is quite clean.
When the circuit is powered up, Vin…
Part Number: TLV6741 Tool/software: Hi,
The example circuit in TLV6741 datasheet demostrates the application of preamplifier for electret microphones. If we plan to use TLV6741 to amplify the differential from condenser microphone with single supply…

Part Number: TLV6741 Other Parts Discussed in Thread: TLV6744 Hi team
In datasheet, this title include TLV6744, but change divisionE to F, this device is deleted.
Why this device deleted ?

Part Number: TLV6742 Other Parts Discussed in Thread: TLV6741 Hi Team,
Why is there huge difference between TLV6741 and TLV6742 in offset voltage drift performance? Are these two dies are different ? You can refer to below screenshots as reference.…
Part Number: TLV6741 Dear TI Experts,
May I know the input impedance of TLV6741? I can't find this parameter in its datasheet. Could you kindly help to advise? Thanks a lot.
Part Number: TLV6741 Other Parts Discussed in Thread: TLV9061 , , TLV9062 Hi
in TLV6741DCKR datasheet, the Absolute Maximum Ratings of TA is 125 degree C.
customer want to know what's the Absolute Maximum Ratings of Tj junction temperature?
is it…
Part Number: TLV9061 Other Parts Discussed in Thread: LMP7731 , TLV6741 Tool/software: Hello, We have designed a 3mm microphone capsule and need to bring the self noise down another 10fb, preferably to around -120db. This Jfet looks potentially viable…
Hi Seeran,
the 120k resistor gives a resistor noise of SQRT(4 x k x T x R x B) = 6.3µVeff. Compared to the sensitivity of micro of -35dBV this corresponds to a signal-to-noise-ratio (SNR) of micro of 20 x log (17.8mV / 6.3µV) = 69dB. This would be a…
Part Number: OPA1671 Other Parts Discussed in Thread: TLV6741 , OPA1641 We are designing signal conditioning for a piezo microphone and are thus concerned with input voltage protection to clamp any high voltages generated from impact to the mic. The OPA1641…
