T he AD1866 operates on +5 V power supplies. T he digital  
supply, VL, can be separated from the analog supply, VS, for re-  
duced digital feedthrough. Separate analog and digital ground  
pins are also provided. In systems employing a single +5 volt  
power supply, VL and VS should be connected together. In bat-  
tery operated systems, operation will continue even with re-  
duced supply voltage. Typically, the AD1866 dissipates 50 mW.  
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 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.  
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.

1. Single supply operation @ +5 V.  
2. 50 mW power dissipation.  
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.  
3. T HD+N is 0.005% (typical).  
4. Signal-to-Noise Ratio is 95 dB (typical).  
5. 115 dB channel separation (typical).  
6. Compatible with all digital filter chips.  
7. 16-pin DIP and 16-pin SOIC packages.  
8. No deglitcher required.  
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×, 4×, 8×, or 16× the sampling frequency (where  
FS = 44.1 kHz) for each channel. T he digital input pins of the  
AD1866 are T T L and +5 V CMOS compatible.  
9. No external adjustments required.
