GENERAL DESCRIPTION
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 re-
sult of continued development in monolithic bipolar technologies.
The complete microprocessor interface and control logic is
implemented with integrated injection logic (I
2
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 sup-
ply. 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 fac-
tory 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 0
°
C to +70
°
C.

PRODUCT HIGHLIGHTS
1. The 8-bit I
2
L input register and fully microprocessor-
compatible control logic allow the AD557 to be directly con-
nected to 8- or 16-bit data buses and operated with standard
control signals. The latch may be disabled for direct DAC
interfacing.
2. The laser-trimmed on-chip SiCr thin-film resistors are cali-
brated for absolute accuracy and linearity at the factory.
Therefore, no user trims are necessary for full rated accuracy
over the operating temperature range.
3. The inclusion of a precision low-voltage band-gap reference
eliminates the need to specify and apply a separate reference
source.
4. The AD557 is designed and specified to operate from a single
+4.5 V to +5.5 V power supply.
5. Low digital input currents, 100
μ
A max, minimize bus loading.
Input thresholds are TTL/low voltage CMOS compatible.
6. The single-chip, low power I
2
L design of the AD557 is inher-
ently more reliable than hybrid multichip or conventional
single-chip bipolar designs.
