register to the DAC input register. T he data clock can function  
at 17 MHz, allowing 16 × FS operation. T he serial input port is  
compatible with second-generation digital filter chips for con-  
sumer audio products such as the NPC SM5813 and SM5818.  
T he AD1862 is a monolithic 20-bit digital audio DAC. Each  
device provides a 20-bit DAC, 20-bit serial-to-parallel input  
register and voltage reference. T he digital portion of the  
AD1862 is fabricated with CMOS logic elements that are pro-  
vided by Analog Devices’ BiMOS II process. T he analog por-  
tion of the AD1862 is fabricated with bipolar and MOS devices  
as well as thin-film resistors.  
T he AD1862 operates with ±5 V to ±12 V supplies for the dig-  
ital power supplies and ±12 V supplies for the analog supplies.  
T he digital and analog supplies can be separated for reduced  
digital crosstalk. Separate analog and digital common pins are  
also provided. T he AD1862 typically dissipates less than  
300 mW.  
New design, layout and packaging techniques all combine to  
produce extremely high performance audio playback. T he de-  
sign of the AD1862 incorporates a digital offset circuit which  
improves low-level distortion performance. Low stress packag-  
ing techniques are used to minimize stress-induced parametric  
shifts. Stress-sensitive circuit elements are located in die areas  
which are least affected by packaging stress. Laser-trimming of  
initial linearity error affords extremely low total harmonic  
distortion. Output glitch is also small, contributing to the over-  
all high level of performance.  
T he AD1862 is packaged in a 16-pin plastic DIP. T he operating  
range is guaranteed to be –25°C to +70°C.

1. 120 dB signal-to-noise ratio. (typical)  
2. 102 dB D-Range performance. (minimum)  
3. ±1 dB gain linearity @ –90 dB amplitude.  
4. 20-bit resolution provides 120 dB of dynamic range.  
5. 16 × FS operation.  
T he noise performance of the AD1862 is excellent. When used  
with the recommended two external noise-reduction capacitors,  
it achieves 120 dB signal-to-noise ratio.  
6. 0.0016% T HD+N @ 0 dB signal amplitude. (typical)  
7. Space saving 16-pin DIP package.  
T he serial input port consists of the clock, data and latch enable  
pins. A serial 20-bit, 2s complement data word is clocked into  
the DAC, MSB first, by the external data clock. A latch-enable  
signal transfers the input word from the internal serial input  
8. ±1 mA output current.
