Audio ADCs Come In Small Packages

The WM8788 and WM8789 stereo audio ADCs come in small, 16-pin TSSOPs that operate from a 3.3V supply. Both feature dual stereo analog audio inputs for capturing line level inputs in the 1-Vrms range with a SNR of 106 dB and a 93 dB THD+N. Input signals greater than 1 Vrms are captured by configuring external resistors. Additionally, the WM8789 features an extra pair of stereo analog inputs. Price for either device is $1.30 each/1,000.
