PRODUCT DESCRIPTION  
A versatile digital interface allows the AD1865 to be directly  
connected to standard digital filter chips. This interface employs  
five signals: Data Left (DL), Data Right (DR), Latch Left (LL),  
Latch Right (LR) and Clock (CLK). DL and DR are the serial  
input pins for the left and right DAC input registers. Input data  
bits are clocked into the input register on the rising edge of  
CLK. A low-going latch edge updates the respective DAC out-  
put. For systems using only a single latch signal, LL and LR  
may be connected together. For systems using only one DATA  
signal, DR and DL may be connected together.  
The AD1865 is a complete, dual 18-bit DAC offering excellent  
THD+N and SNR while requiring no external components. Two  
complete signal channels are included. This results in cophased  
voltage or current output signals and eliminates the need for  
output demultiplexing circuitry. The monolithic AD1865 chip  
includes CMOS logic elements, bipolar and MOS linear ele-  
ments and laser-trimmed thin-film resistor elements, all fabri-  
cated on Analog Devices’ ABCMOS process.  
The DACs on the AD1865 chip employ a partially segmented  
architecture. The first four MSBs of each DAC are segmented  
into 15 elements. The 14 LSBs are produced using standard R-2R  
techniques. Segment and R-2R resistors are laser trimmed to pro-  
vide extremely low total harmonic distortion. This architecture  
minimizes errors at major code transitions resulting in low out-  
put glitch and eliminating the need for an external deglitcher.  
When used in the current output mode, the AD1865 provides  
two ±1 mA output signals.  
The AD1865 operates with ±5 V power supplies. The digital  
supply, VL, can be separated from the analog supplies, VS and  
–VS, for reduced digital feedthrough. Separate analog and digital  
ground pins are also provided. The AD1865 typically dissipates  
only 225 mW, with a maximum power dissipation of 260 mW.  
The AD1865 is packaged in both a 24-pin plastic DIP and a  
28-pin SOIC package. Operation is guaranteed over the temper-  
ature range of –25°C to +70°C and over the voltage supply  
range of ±4.75 V to ±5.25 V.  
Each channel is equipped with a high performance output am-  
plifier. These amplifiers achieve fast settling and high slew rate,  
producing ±3 V signals at load currents up to 8 mA. Each out-  
put amplifier is short-circuit protected and can withstand indefi-  
nite short circuits to ground.  
PRODUCT HIGHLIGHTS  
11. The AD1865 is a complete dual 18-bit audio DAC.  
12. 110 dB signal-to-noise ratio for low noise operation.  
13. THD+N is typically 0.003%.  
14. Interchannel gain and midscale matching.  
15. Output voltages and currents are cophased.  
16. Low glitch for improved sound quality.  
17. Both channels are 100% tested at 16 × FS.  
18. Low Power—only 225 mW typ, 260 mW max.  
19. Five-wire interface for individual DAC control.  
10. 24-pin DIP or 28-pin SOIC packages available.  
The AD1865 was designed to balance two sets of opposing re-  
quirements, channel separation and DAC matching. High chan-  
nel separation is the result of careful layout. At the same time,  
both channels of the AD1865 have been designed to ensure  
matched gain and linearity as well as tracking over time and  
temperature. This assures optimum performance when used in  
stereo and multi-DAC per channel applications.
