DACPORT Low Cost, Complete µP-Compatible 8-Bit DAC

The AD557 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 low cost and versatility of the AD557 DACPORT are the result of continued development in monolithic bipolar technologies.
The complete Microprocessor Interface and control Logic is implemented with integrated injection Logic (I2 L), an extremely dense and low-power Logic structure that is process-compatible with linear bipolar fabrication. The internal precision Voltage Reference is the patented low-voltage band-gap circuit which permits full-accuracy performance on a single +5 V power supply. Thin-film silicon-chromium resistors provide the stability required for guaranteed monotonic operation over the entire operating temperature range, while laser-wafer trimming of these thin-film resistors permits absolute calibration at the factory to within 2.5 LSB; thus, no user-trims for gain or offset are required. A new circuit design provides voltage settling to 1/2 LSB for a full-scale step in 800 ns.
The AD557 is available in two package configurations. The AD557JN is packaged in a 16-pin plastic, 0.3"-wide DIP. For surface mount applications, the AD557JP is packaged in a 20-pin JEDEC standard PLCC. Both versions are specified over the operating temperature range of 0C to +70C.
DACPORT is a registered trademark of Analog Devices, Inc. Covered by U.S. Patent Nos. 3,88,863; 3,685,045; 4,323,795; other patents pending.
