input
• 3-stage digital filter incorporating F.I.R. filter, linear interpolator and sample and hold
• 2nd order noise shaper to provide a signal-to-noise ratio of> 90 dB
• 16-bit resolution from a 1-bit converter, using switched capacitor integrator
• 3rd order low-pass filter to reduce out-of-band noise
• -12 dB attenuation, de-emphasis and mute control
• Low power consumption (typ. 300 mW)
• Single supply operation (+ 5 V)
• -40 to + 85 0C operating temperature range
