Part Number: TIDA-00826 Other Parts Discussed in Thread: LMH6559 Hi team,
Customer use Fluke9500 to monitor the input impedance of LMH6559, while the it is only 50ohm when offset is 0. the input impedance change with offset change, do we have methods…
Part Number: TIDA-00826 Other Parts Discussed in Thread: LMH6401 Hi,
I took the TIDA-00826 as reference and built the simulation by myself as i could not get the complete TINA Simulation file
I am stuck at changing the parameters of the PGA LMH6401…
Part Number: TIDA-00826 Other Parts Discussed in Thread: LMX2594 , ADC12DJ5200RF , ADC12J4000 , ADC12DJ5200RFEVM Dear team,
Customer wants to know some details about PCB of TIDA-00826:
1. Do we have the info of TIDA-00826 stack-up reference materials…
Hi Kerb,
The pcb layout and gerber file for the TIDA-00826 are available in this link at the very bottom: http://www.ti.com/tool/TIDA-00826

Part Number: LMH6401 In the TIDA-00826 reference design schematics, there are some 'DNP' capacitors in parallel with the PI attenuator resistors. What's the purpose? When we need populate these capacitors?
Thanks.
Part Number: ADC12J4000 Other Parts Discussed in Thread: TIDA-00826 , LMH6401 , ADC3662 , On the TIDA-00826 reference design, an LMH6401 is used on an automatic gain control (AGC) loop with ADC ADC12J4000. Why is this block necessary on an oscilloscope…
I'm also curious if the voltage rails should be set differently to optimize voltage range. right now I have +/- 2.5V rails set for the EVM, but i've seen reference designs (TIDA-00826) that use +3.75V and -1.25V rails for the LMH5401.
Dear Sir,
Very thanks for your valuable time allotted in answering
My signal is 250MHz so i am choosing 500Msps ADC, you are correct the signal is a single-ended
I have gone through TI 2 GHz OscilloScope design which i felt is a good starting point…
