3.5.9 Function introduction to CS5340
1. Description
CS5340 is a kind of complete A/D converter used in digital audio system. It has sampling, A/D conversion
and anti-aliasing filtering function, and can generate 24-bit sampling frequency to left and right channels with
serial value of each channel up to 2000 KHz. A 5-step multi-bit DELTA-SIGMA modulator is adopted, with
digital filtering and simplification function, so external anti-aliasing filter is not needed. It is specially applicable
for audio system required wide dynamic range, Hi-Fi and low noise.
2. Features
# Support all sampling frequency including 192 KHZ
# Dynamic range is 101dB when voltage is 5V
# -94 dB THD+N
# Highpass filter may remove DC offset
# Low delay digital filter
# Power consumption is 90 milliwatt under 3.3V power supply
# A/D inner core power supply voltage is 3.3V ~ 5V
# Support 1.8V ~ 5V logic level
