The PCM56P is a state-of-the-art, fully monotonic, digital-to-analog converter that is designed and specified for digital audio applications. This PCM56P employs ultra-stable nichrome (NiCr) thin-film resistors to provide monotonicity, low distortion, and low differential linearity error (especially around bipolar zero) over long periods of time and over the full operating temperature.

This converter PCM56P is completely self-contained with a stable, low noise, internal zener voltage reference; high speed current switches; a resistor ladder net-work; and a fast settling, low noise output operational amplifier all on a single monolithic chip. The converters PCM56P are operated using two power supplies that can range from ±5V to ±12V. Power dissipation with ±5V supplies is typically less than 200mW. Also included is a provision for external adjustment of the MSB error (differential linearity error at bipolar zero) to further improve total harmonic distortion (THD) specifications if desired. Few external components of PCM56P are necessary for operation, and all critical specifications are 100% tested. This helps assure the user of high system reliability and outstanding overall system performance.

The PCM56P is packaged in a high-quality 16-pin molded plastic DIP package or SOIC and has passed operating life tests under simultaneous high-pressure, high-temperature, and high-humidity conditions.
