A 110dB ternary PWM current-mode audio DAC with monolithic 2Vrms driver

Timothy Thomas Rueger; Bruce Eliot Duewer; Stephen T. Hodapp; Tom Gong Lei; John L. Melanson; Brian David Trotter

A /spl Delta//spl Sigma/ audio DAC uses a 4b quantizer, ternary PWM encoding, and semidigital current-mode FIRs for 110dB dynamic range over 20kHz. The IC achieves -99dB THD driving a single-ended 2V/sub rms/ signal into a 5k/spl Omega/ load. Die area is 5.98mm/sup 2/ in a 0.35/spl mu/m/3.3V process with a 3/spl mu/m/18V module.
