2. DAC Characteristics

In addition to the DAC, these characteristics include the built-in post filter and trim volume. Use the digital input

and analog output circuits in the Application Circuit for the measurement circuit.

2-1. When Pro Logic mode is on

Unless otherwise specified, the measurement conditions are as given below.

• Digital data = –20dBFS

• fIN = 3kHz
