T he AD1868 is a complete dual 18-bit DAC offering excellent  
performance while requiring a single +5 V power supply. It is  
fabricated on Analog Devices’ ABCMOS wafer fabrication pro-  
cess. T he monolithic chip includes CMOS logic elements, bipo-  
lar and MOS linear elements, and laser-trimmed thin-film  
resistor elements. Careful design and layout techniques have re-  
sulted in low distortion, low noise, high channel separation, and  
low power dissipation.  
T he AD1868 operates on +5 V power supplies. T he digital sup-  
ply, 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 reduced  
supply voltage. T ypically, the AD1868 dissipates 50 mW.  
T he DACs on the AD1868 chip employ a partially segmented  
architecture. T he first three MSBs of each DAC are segmented  
into seven elements. T he 15 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 AD1868 requires no deglitcher or trimming circuitry. Low  
noise is achieved through the use of two noise-reduction capacitors.  
T he AD1868 is packaged in either a 16-pin plastic DIP or a 16-  
pin plastic SOIC package. Operation is guaranteed over the tem-  
perature range of –35°C to +85°C and over the voltage supply  
range of 4.75 V to 5.25 V.

1. Single-supply operation @ +5 V.  
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  
buffered output signal range is 1.5 V to 3.5 V. Reference volt-  
ages of 2.5 V are provided, eliminating the need for “False  
Ground” networks.  
2. 50 mW power dissipation (typical).  
3. T HD+N is 0.004% (typical).  
4. Signal-to-Noise Ratio is 97.5 dB (typical).  
5. 108 dB channel separation (minimum).  
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 AD1868 to be directly  
connected to all digital filter chips. Fast CMOS logic elements  
allow for an input clock rate of up to 13.5 MHz. T his allows for  
operation at 2×, 4×, 8×, or 16× the sampling frequency for each  
channel. T he digital input pins of the AD1868 are T T L and  
+5 V CMOS compatible.  
9. No external adjustments required.
