Hi Betul,
VCA822 is the more accurate device. You may also look into the VCA821, LMH6505, and LMH6503 as they have better accuracy as well.
Since these devices have internal gain adjust circuitry, there is no way to improve the accuracy of the gain unfortunately…
Other Parts Discussed in Thread: LMH6505 Is there a simple way to drastically reduce the bandwidth of the LMH6505 to just good audio? (And thus reduce possible oscillation.) I've done all the surface mount, remove ground plane, short lead stuff.
Thanks…
Other Parts Discussed in Thread: LMH6505 , LMH6504 Looking at the 6505 data sheet and comparing it to the 6504 I notice the 6504 shows two VGA circuits. The second (with fewer parts) is not on the 6505 data sheet. Is this second VGA circuit applicable to…
Hello Tess,
Please see this existing discussion where Sima refers to the VCA820's datasheet page 34, with the linked e2e for a small edit: https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1171251/lmh6505-agc-circuits-at-v-v…
Other Parts Discussed in Thread: LMH6505 , LMH6714 , LMH6401 , LMH6517 Hi all, Would mind if we ask LMH6505 and LMH6714? <Q1> How long is the internal delay from input to output?(ns? us? it means latency with internal processing) The datasheet P2 shows Time…
Other Parts Discussed in Thread: LMH6502 , LMH6505 Hi All,
Could you please share the NF(Noise Figure) for LMH6502 and LMH6505? My customer wants to compare a NF based performance between TI and competitors.
Regards, Toshi
Other Parts Discussed in Thread: LMH6505 , LMH730066 Hi all, Would you mind if we ask LMH6505? The datasheet P18 indicates "Cut away the ground plane, if any, under RG." <Q1> Why is cut away the ground plane required? <Q2> About, our customer…
Other Parts Discussed in Thread: LMH6505 hiall,
And AvMax=100V/V is usefull, see snosat4e.pdf and pabe 6 Fregaurecy Rseponse for Various VG(AVMAV = 100) . In a reference example, they are RF=2.32komega and RG=18ohm.
>RG=18ohm was not able to be chosen from…
Part Number: TL026 Other Parts Discussed in Thread: LMH6505 , THS7530 , VCA810 I'm looking for an AGC amplifier replacement for the venerable MC1350 and are looking at the TL026 but it doesn't seem to be applicable as a replacement. Have I missed something…
