A family of current-steering transimpedance amplifier circuits is presented for use in high-resolution digital-to-analog converters. The problems of achieving accurate current-to-voltage conversion are discussed, with a specific emphasis on digital audio applications. Comparisons are made with conventional virtual-earth feedback amplifiers, and the inherent distortion mechanisms relating to dynamic open-loop gain are discussed. Motivation for this work follows the introduction of DVD-Audio carrying linear PCM with a resolution of 24 bit at a sampling rate of 192 kHz.
