Part Number: PCM1822 Other Parts Discussed in Thread: PCM1821 , PCM1861
Hi:)
-
Does the PCM1822/PCM1821 support Single-Ended stereo Line-Inputs for standard auxiliary audio, or would the PCM1861 be a better fit for this?
Also, are any circuit diagrams available…
Part Number: PCM1822 Is this ADC specially designed for different MEMS microphone signals? Can I use near-field microphone signals in combination with a preamp to feed this ADC? If not, what are the risks?

Part Number: PCM1822 The absolute maximum rating for the analog inputs to the ADC at the low end is -0.3V. Recommended anlog input range is 0 to AVDD (+3.3V). With a 2Vpp input, wouldn't AC-coupling cause the input signal to swing to -1V, violating the…
Part Number: PCM1822 Hello Experts, The full scale AC signal voltage is stated 1Vrms(typ) in datasheet. The condition is AVDD is 3.3V. If AVDD is 3.1V, it will be reduced? Also if AVDD is 3.1V, the other spec(SNR, DR and so on) will be reduced? Best Regards…
Part Number: PCM1822 Hello Experts, If customer would like to use a single-ended input(signal input INP-pin), how customer should treat INM-pin? INM-pin connects a GND through capacitor(same value of INP-pin AC coupling capacitor)? Best Regards, Fujiwar…

You see this in the datasheet of the PCM1822. Its a few pages into the datasheet.
The setup for single ended inputs is correct
Part Number: PCM1821 Other Parts Discussed in Thread: PCM1822-Q1 , PCM1820 , PCM1820-Q1 If only one channel of the PCM1821 analog input pair is needed, what is the recommended connection for the other pair?
Does this same recommendation apply to PCM1820…
Part Number: PCM1821 Other Parts Discussed in Thread: PCM1822-Q1 We need to make sure our PCM1821 (or PCM1822-Q1) board is as quiet as possible, but the system we're connecting to is fairly noisy. Thus we want to isolate our analog signals, power…
