Part Number: PROCESSOR-SDK-AM62X Other Parts Discussed in Thread: AM6252 , SK-AM62B-P1 Hi, experts
Hello, I have a question regarding the AM6252 custom board and Audio.
I created a custom board by modifying the circuit using the SK-AM62B-P1 base and installed…
Hey Roger,
This app note covers how we modernly test our op amps: EMI Rejection Ratio of Operational Amplifiers (With OPA333 and OPA333-Q1 as an Example)
Figure 10 shows the circuit configuration, the DIY amp boards can be used to build a buffer (gain…
Part Number: TAS2780EVM Other Parts Discussed in Thread: TAS2780 , PUREPATHCONSOLE Hello TI Audio Team,
I've been evaluating the TAS2780EVM with a 4Ohm speaker capable of 35W. I have the TAS2780EVM connected to a 23V programmable power supply with a…
Part Number: TPA3255 Hi,
we have two possibly related issues with the TPA3255:
In our design - but not on TPA3255EVM or a "Cheap and cheerful" ready-made Amplifier -
we encounter dropouts at relatively low output power (~100W RMS into 4Ω) (whereas…
Hello,
Thank you for the fast reply.
Test conditions are as follows:
PSU configuration : 42V @ 3AMP CC connected at the input of the EVM
Battery Pack connected to the output of the EVM (Battery Parameters 36V, 12.8 Ah - 460.8Wh )
Battery charging voltage…
Part Number: ADS1285EVM-PDK Other Parts Discussed in Thread: ADS1285 Hi team,
I was looking at the ADS1285-EVM circuit, I found a functional circuit in the ADC front end (picture below). If I'm using a single-ended input, what does this circuit do, filter…
Hey David,
Have you looked at the OPA1656? This is one of our modern Burr Brown devices that has ultra low noise and has great THD specifications. It does not come in the dip package however we do have coupon board that converts into pins that can be…
Dear Vijay,
Thanks for the reply
1.) Once we ran S1_OnboardClk_RX_250M_TX_FB_500M.py script current drawn by AFE EVM is approx 3.925 Amps and TSW EVM is approx 1.728Amps at 12V
2.) Yes LED D2 on TSW blinks once we click send button
3.) LED D3 on AFE EVM…
Here re some preliminary comments:
Remove the low-side FET gate resistors - these are effectively never used (0Ω just compromised the layout and increases gate loop inductance).
Input ceramics should be 2.2uF/100V and placed close to the FETs…
