What is the ADC resolution of the Wolfson CODEC used ? I've seen 24bits, 16bits, 12bits ?? Is the 24bits differential Audio ? and the 12bits single ended Audio ? How do I access the 3 12bit ADCs on the STM chip from the DISCO I/O ?

Hi, I need a free sample of TDA7265B. It is a class-AB two-channel power amplifier. I didn't find in a list of free samples of integrated circuits of its class. There is a TDA7265 chip, it is very similar but not the same. What ca I do in this case? Thank you in advance.

Just wondering if there is any sample code or application notes....   Regards   Anthony

Hi,   Trying to program STDP6028,   Able to read registers from GProbe tool. But when I try to program Hex file. Tool shows progress of flash write. But after complete, no other prints come on the console. On very reset I will only get "IROM 1.2" on UART. Please guide me how to flash to external flash and boot from it.   Regards, Dileep

Hi everyone,   I'm looking for some help after many days of pain. I'm trying to write basic uSD to I2S application, but the result is really ugly. I'm using STM3240G eval board and Adafruit MAX98357 board.   I'm using fatfs and sdio to read a wave file on my uSD card. I'm filling 2 or 3 buffers and sending data through I2S at the same time.… (Show more)

Placing a CS30A next to a 0.05ohm sense ohm successfully measured output currents from 24v boost converter.   Since the microcontroller was not nearby, to reduce noise thought it might be better to place the CS30A next to the uC (with a low pass filter) and run two lines to the sense resistor. On the grounds that a) the longer traces should be… (Show more)

Hello everyone. I would like to know if is possible to use the CS30 current sense amplifier with inductive loads, i.e. something similar to the coils of solenoids used in automatic car gearboxes. Thanks in advance.   The operating conditions are 12V and about 1 to 2A.

Hi, I'm looking for an op-amp to buffer a signal and provide an output of 2 -> 5V to a load of 100 - 200R. This would require driving the load with 50 - 100 mA. The LMX358IQ2T has a specified output source current of 60-70 mA, but I'm not sure if this just means an absolute max or a max where the output voltage signal will be maintained? Will the… (Show more)
