Digitally Controlled Microphone Preamplifier
Features
D Fully Differential Input-to-Output Architecture D Digitally Controlled Gain Using Serial Port
Interface:
- Gain Range: 10dB through 65dB, 1dB per step
- Unity (0dB) Gain Setting via Serial Port or Dedicated Control Pin Dynamic Performance:
- Equivalent Input Noise with ZS = 150Ω and Gain = 30dB:
- 128dBu
- Total Harmonic Distortion plus Noise (THD+N) with Gain = 30dB: 0.0004% Zero Crossing Detection Minimizes Audible Artifacts when Gain Switching Integrated DC Servo Minimizes Output Offset Voltage mon-Mode Servo Improves CMRR Four-Wire Serial Control Port Interface:
- Simple...
