... External Filter) NOTES: (1) Measured at V Pin (Pin 13 or 16). OUT (2) The PCM1715 has internal analog low pass filter to reduce high frequency noise-shaped spec- trum. Application of the PCM1715 requires external post analog low pass filter which has 2nd-Order or 3rd-Order attenuation performance to get low noise analog output ...
