Part Number: LMH6521 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models I noticed a few distinctions where the simulation result of the spice model in ADS does not meet the curves in the datasheet.
I would like to get clarified…
Other Parts Discussed in Thread: LMH6521 , LMH6517 I am in need of a dual programmable gain fully differential amplifier for using on an I/Q demodulator to provide some additional dynamic range but I need the frequency response to go down to at least 1…
Hi Robert,
The LMH6521 gain is a voltage gain. (20*log(Vout/Vin)). Your calculated gains are correct. I still cannot figure out why the gain steps are 1/2 the expected gain change.
I will review the schematic again and get back to you. I think…
Other Parts Discussed in Thread: LMH6521 Hi,
I'm using LMH6521 on a new board.
I've some difficulties to control the amplifier in Serial mode.
I can correctly write and read the device trough the SPI pins.
Aftern enabloing the ENB or ENA i see…

HI i have recently encountered an issue with LMH6521 for my oscilloscope design project.
How accurate is the spice model for this part? I am asking This because on TINA TI simulation the amplifier works for low…
Other Parts Discussed in Thread: LMH6521 Hallo,
I have a question. I think that the output gain of the LMH6521 is (26dB – Attenuator Gain). Is my understanding correct?
Our customer ask us. They set the digital attenuator to 18dB (C8h) referring to…
Other Parts Discussed in Thread: LMH6521 Hallo,
The LMH6521 mentions below in page-14 with Figure 30. “ Make sure to check the inductor datasheet to not exceed the maximum current limit. “ Could you please let me know how to calculate the inductor…
Other Parts Discussed in Thread: LMH6521 I'm working on a design using the LMH6521 DVGA and I've been trying to setup a simulation using the ADS2009 spice model found at ( http://www.ti.com/product/LMH6521/toolssoftware ).
I'm running ADS2009U1 and…
Other Parts Discussed in Thread: LMH6521 Hi Team,
Do we have measured s-parameters (s2p files) of the LMH6521 for its operation over frequency and gain (such as fig.4 in the datasheet), so I can model it for the system.
Thanks,
Max
