GENERAL DESCRIPTION
The AD7569/AD7669 is a complete, 8-bit, analog I/O system
on a single monolithic chip. The AD7569 contains a high speed
successive approximation ADC with 2
μ
s conversion time, a track/
hold with 200 kHz bandwidth, a DAC and an output buffer ampli-
fier with 1
μ
s settling time. A temperature-compensated 1.25 V
bandgap reference provides a precision reference voltage for the
ADC and the DAC. The AD7669 is similar, but contains two
DACs with output buffer amplifiers.
A choice of analog input/output ranges is available. Using a sup-
ply voltage of +5 V, input and output ranges of zero to 1.25 V
and zero to 2.5 volts may be programmed using the RANGE in-
put pin. Using a
±
5 V supply, bipolar ranges of
±
1.25 V or
±
2.5 V may be programmed.
Digital interfacing is via an 8-bit I/O port and standard micro-
processor control lines. Bus interface timing is extremely fast, al-
lowing easy connection to all popular 8-bit microprocessors. A
separate start convert line controls the track/hold and ADC to
give precise control of the sampling period.
The AD7569/AD7669 is fabricated in Linear-Compatible
CMOS (LC
2
MOS), an advanced, mixed technology process
combining precision bipolar circuits with low power CMOS
logic. The AD7569 is packaged in a 24-pin, 0.3" wide “skinny”
DIP, a 24-terminal SOIC and 28-terminal PLCC and LCCC
packages. The AD7669 is available in a 28-pin, 0.6" plastic
DIP, 28-terminal SOIC and 28-terminal PLCC package.

PRODUCT HIGHLIGHTS
1. Complete Analog I/O on a Single Chip.
The AD7569/AD7669 provides everything necessary to
interface a microprocessor to the analog world. No external
components or user trims are required and the overall accu-
racy of the system is tightly specified, eliminating the need
to calculate error budgets from individual component
specifications.
2. Dynamic Specifications for DSP Users.
In addition to the traditional ADC and DAC specifications,
the AD7569/AD7669 is specified for ac parameters, includ-
ing signal-to-noise ratio, distortion and input bandwidth.
3. Fast Microprocessor Interface.
The AD7569/AD7669 has bus interface timing compatible
with all modern microprocessors, with bus access and relin-
quish times less than 75 ns and write pulse width less than
80 ns.
