Overview

The AD558TD DACPORT? is a complete voltage-output 8-bit digital-to-analog converter, including output amplifier, full microprocessor interface and precision voltage reference on a single monolithic chip. No external components or trims are required to interface, with full accuracy, an 8-bit data bus to an analog system. The performance and versatility of the DACPORT is a result of several recently-developed monolithic bipolar technologies. The complete microprocessor interface and control logic is imple-mented with integrated injection logic(FL), an extremely denseand low power logic structure that is process-compatible with linear bipolar fabrication. The internal precision voltage reference is the patented low voltage bandgap circuit which permits full- accuracy performance on a single +5 V to +15 V power supply. Thin-film silicon-chromium resistors provide the stability re-quired for guaranteed monotonic operation over the entire oper-ating temperature range(all grades), while recent advances in laser-wafer-trimming of these thin-film resistors permit absolute calibration at the factory to within ±1 LSB; thus no user-trims for gain or offset are required.A new circuit design providesvoltage settling to ±1/2 LSB for a full-scale step in 800 ns. The AD558TD is available in four performance grades. The AD558J and K are specified for use over the OC to +70℃ temperature range, while the AD558S and T grades are specified for-55℃ to +125C operation. The "J"and "K"grades are available either in 16-pin plastic(N) or hermetic ceramic(D) DIPS. They are also available in 20-pin JEDEC standard PLCC packages. The "S"and "T"grades are available in the 16-pin hermetic ceramic DIP package.
