AD558TD

The settling time of the AD558 DACPORT for a full-scale step is specified to be ±1/2 LSB in 800 ns.

The AD558 DACPORT is a complete voltage-output 8-bit digital-to-analog converter that includes an output amplifier, full microprocessor interface, and precision voltage reference on a single monolithic chip. It does not require any external components or trims to interface an 8-bit data bus to an analog system with full accuracy. The AD558 is available in four performance grades, with different temperature ranges for each grade. The DACPORT is designed to be directly connected to 8- or 16-bit data buses and operated with standard control signals, with the latch being able to be disabled for direct DAC interfacing. The performance and versatility of the DACPORT are achieved through recently-developed monolithic bipolar technologies, including integrated injection logic (I2L) for the microprocessor interface and control logic, a patented low voltage bandgap circuit for the precision voltage reference, and laser-wafer-trimmed thin-film resistors for calibration. The AD558 also features fast voltage settling to ±1/2 LSB for a full-scale step in 800 ns.

The voltage range of the AD558 DACPORT is 0 V to +10 V or 0 V to +2.56 V, selectable by pin-strapping .
