Part Number: PCM2912A Hello team,
I want to estimate the Max output voltage swing of this device. From the datasheet, the output voltage is specified as below.
If I am using VCCA=3.3V, and RL>10kohm, would the max output voltage swing be 0.66V to 2…
Part Number: PCM2912A I am seeing the similar issue like below that 20% of the chips output 0.6Vpp not 1.98Vpp to the >10kOhm impedance. "DAC specifies a 0.6 * Vcca (1.98Vpp) output with Rl > 10k load. However i am only getting 0.554Vpp measured at…
Part Number: PCM2912A Due to shock requirements we cannot use a crystal.
Can the VDD output be used to power a 4.5mA MEMS oscillator?
If the MIC (VIN) is unused should the pin be left floating or tied to some level?
