Other Parts Discussed in Thread: TLV320ADC3140
We know TLV320ADC3120 support single-ended input.(INxP ->Input,INxN->GND)
We have an idea about frequency testing( Test item: frequency and Amplitude ).
Below is the test Block diragram, Does it work by the below topology? (Input 0~+1V, Freq<100Khz, square wave or sine wave)
Input Connect to TLV320ADC3120 directly, or do we need a coupling cap?
Does TLV320ADC3120 support single-ended input (IN1) +PDM MIC(IN2) working at the same time?
The same question about TLV320ADC3140...
