CS53L21
CS53L21 is Stereo Analog-to-Digital Converter manufactured by Cirrus Logic.
FEATURES
98-d B dynamic range (A-weighted)
- 88-d B THD+N Analog gain controls
- +32-d B or +16-d B mic preamps
- Analog programmable gain amplifier (PGA)
+20-d B digital boost Programmable automatic level control (ALC)
- Noise gate for noise suppression
- Programmable threshold and attack/release rates
Independent left/right channel control Digital volume control High-pass filter disable for DC measurements Stereo 3:1 analog input MUX Dual mic inputs
- Programmable, low noise mic bias levels
- Differential mic mix for mon mode noise rejection
Very low 64 Fs oversampling clock reduces power consumption
