Wolfson Microelectronics plc announced a new version of its WM8718 differential stereo DAC, in smaller packaging and specified over an extended operating temperature range.

Offered in a 4x4mm QFN package, the WM8718QFN has a 111dB signal to noise ratio (‘A’ weighted at 48kHz) and -100dB total harmonic distortion. Left and right zero flag outputs allow control of external mute circuits. The WM8718QFN is specified for operation over the automotive temperature range of -40 to +85 degrees centigrade.

The device supports PCM data input word lengths from 16 to 32-bits and sampling rates of 192kHz.

The WM8718 is available now in volume quantities in a 24-pin QFN package. The existing 20-pin SSOP device will continue to be available alongside the new version.
