These devices employ ul- tra-stable nichrome (NiCr) thin-film resistors to pro- vide monotonicity, low distortion, and low differential linearity error (especially around bipolar zero) over long periods of time and over the full operating temperature. These converters are completely self-contained with a stable, low noise, internal, zener voltage reference; high speed current switches; a resistor ladder network; and a fast settling, low noise output opera- tional amplifier all on a single monolithic chip. The converters are operated using two power supplies that can range from ±5V (PCM55) to ±12V (PCM54). Power dissipation with ±5V supplies is typically less than 200mW. Also included is a provision for exter- nal adjustment of the MSB error (differential linearity error at bipolar zero, PCM54 only) to further improve Total Harmonic Distortion (THD) specifications if desired. A current output (I OUT) wiring option is provided. This output typically settles to within ±0.006% of FSR final value in 350ns (in response to a full-scale change in the digital input code). The PCM54 is packaged in 28-pin plastic DIP pack- age. The PCM55 is available in a 24-lead plastic mini- flatpak. 16-Bit Ladder Resistor Network and Current Switches Reference Voltage Parallel Digital Input R F Output Operational Amplifier Audio Output (Voltage) ® International Airport Industrial Park • Mailing Address: PO Box 11400, Tucson, AZ 85734 • Street Address: 6730 S.
