5 Application Information
5.1
Single-Ended to Differential External Analog Front-End Circuit
(fs = 44.1 kHz)
A single-ended to differential external analog front-end example circuit is shown in Figure 5–1. It biases the
input signal around AVDD/2 and applies the maximum input signal of 0.7 Vrms. The device sees a full-scale
differential input voltage of approximately 4 Vpp. For other maximum input signals, the ratio of R2/R1 can
be scaled accordingly to ensure a max ADC input of approximately 4 Vpp. As required by the ADC, R5, C4,
and R6 provide a single-pole low-pass antialiasing filter to attenuate unwanted frequencies. If the user
chooses to supply a single-ended input directly to the device (2 Vpp max), performance will be significantly
degraded.
