PRODUCT DE SCRIPT ION
T he AD1866 is a complete dual 16-bit DAC offering excellent
performance while requiring a single +5 V power supply. It is
fabricated on Analog Devices’ ABCMOS wafer fabrication
process. T he monolithic chip includes CMOS logic elements,
bipolar and MOS linear elements and laser trimmed, thin-
film resistor elements. Careful design and layout techniques
have resulted in low distortion, low noise, high channel separa-
tion and low power dissipation.
T he DACs on the AD1866 chip employ a partially segmented
architecture. T he first three MSBs of each DAC are segmented
into 7 elements. T he 13 LSBs are produced using standard
R-2R techniques. T he segments and R-2R resistors are laser
trimmed to provide extremely low total harmonic distortion.
T he AD1866 requires no deglitcher or trimming circuitry.
Each DAC is equipped with a high performance output ampli-
fier. T hese amplifiers achieve fast settling and high slew rate,
producing
±
1 V signals at load currents up to
±
1 mA. T he buff-
ered output signal range is 1.5 V to 3.5 V. T he 2.5 V reference
voltages eliminate the need for “false ground” networks.
A versatile digital interface allows the AD1866 to be directly
connected to all digital filter chips. Fast CMOS logic elements
allow for an input clock rate of up to 16 MHz. T his allows for
operation at 2

the sampling frequency (where
F
S
= 44.1 kHz) for each channel. T he digital input pins of the
AD1866 are T T L and +5 V CMOS compatible.

T he AD1866 operates on +5 V power supplies. T he digital
supply, V
L
, can be separated from the analog supply, V
S
, for re-
duced digital feedthrough. Separate analog and digital ground
pins are also provided. In systems employing a single +5 volt
power supply, V
L
and V
S
should be connected together. In bat-
tery operated systems, operation will continue even with re-
duced supply voltage. T ypically, the AD1866 dissipates 50 mW.
T he AD1866 is packaged in either a 16-pin plastic DIP or a
16-pin plastic SOIC package. Operation is guaranteed over the
temperature range of –35
°
C to +85
°
C and over the voltage
supply range of 4.75 V to 5.25 V.
