Part Number: TAS2781 Tool/software: I'm reviewing a new amp chip and I'm reviewing TAS2781
because the functionality of smart amp is attractive. It is essential that I need PPC software.
I looked at the document and the circuit configuration of…
Part Number: INA190 Other Parts Discussed in Thread: INA186 , , THS3120 , INA193 Hello,
I would like to know what options may exist for the INA190Ax using the SOT23-8 package inside TI's current sense amp or instrumentation amp which would allow me to design…
Hello Craig,
There is not a specified maximum current for the BQ27z561 EVM (not sure why this was not documented). However, I think anything less than 5 amps should be completely fine. The rate of discharge does matter. The discharge needs to be between…
A digital input amp would be great, but I already asked here:
"Which stereo speaker amp EVMs take digital input from a USB cable (from Linux PC)?"

Hello Ryan,
Can I get the information about the RLD Amp, (its characteristics), because we were not sure about patient protection. In the EVM User manual, The RLDOUT pin is directly connected to patient electrode. But it seems a bit risky to connect it…
Part Number: TLV320AIC3206 Hello
I would like to inquire because the audio in the custom board is not currently working.
I am using the TLV320AIC3106IRGZT + Amp circuit TPA3111D3111 and it is connected to a speaker (8Ω, 8W), but it does not work.…
1. After the removal of failed MCU, do you still see a short on hardware. Please check the decoupling caps between VDDA and VSSA, or examine board closely for another cause of a short.--> this elimates the problem with the hardware if any.

Hi Jean,
It looks like you are using the default characterization for the speaker. you will need to characterize the speaker to get the full performance out of the smart amp algorithm. i believe this is why you are seeing low power from the amplifier…
Thank you for the fast response and advice to use the DS values.
Inductor rating is Isat_max = 9.3A, Irms_20C = 8.5A, DCR=14.4 mR.
TPS61178 current limit R= 180k --> 4 amp max. In the full circuit, Iout max will be only 1.5A.
I have been testing at…
Hi SUNDARAMOORTHI,
The benefits of TPS23756 is its low 9-V PWM CTL UVLO. It is good for wide input voltage range. For example TPS23756EVM has 12-57V input range. TPS23734 and TPS23731 are the newest 25.5-W PD parts, please see their features below. TPS23731EVM…
