T he critical specifications of T HD+N and signal-to-noise ratio  
are 100% tested for all devices.  
T he AD1851/AD1861 is a monolithic PCM audio DAC. T he  
AD1851 is a 16-bit device, while the AD1861 is an 18-bit de-  
vice. Each device provides a voltage output amplifier, DAC,  
serial-to-parallel register and voltage reference. T he digital por-  
tion of the AD1851/AD1861 is fabricated with CMOS logic  
elements that are provided by Analog Devices’ 2 µm ABCMOS  
process. T he analog portion of the AD1851/AD1861 is fabri-  
cated with bipolar and MOS devices as well as thin-film  
resistors.  
T he AD1851/AD1861 operates with ±5 V power supplies, mak-  
ing it suitable for home use markets. T he digital supply, VL, can  
be separated from the analog supplies, VS and –VS, for reduced  
digital crosstalk. Separate analog and digital ground pins are  
also provided. Power dissipation is 100 mW typical.  
T he AD1851/AD1861 is available in either a 16-pin plastic DIP  
or a 16-pin plastic SOIC package. Both packages incorporate  
the industry standard pinout found on the AD1856 and  
AD1860 PCM audio DACs. As a result, the AD1851/AD1861  
is a drop-in replacement for designs where ±5 V supplies have  
been used with the AD1856/AD1860. Operation is guaranteed  
over the temperature range of –25°C to +70°C and over the  
voltage supply range of ±4.75 V to ±5.25 V.  
T his combination of circuit elements, as well as careful design  
and layout techniques, results in high performance audio play-  
back. Laser-trimming of the linearity error affords low total har-  
monic distortion. An optional linearity trim pin is provided to  
allow residual differential linearity error at midscale to be elimi-  
nated. T his feature is particularly valuable for low distortion  
reproductions of low amplitude signals. Output glitch is also  
small, contributing to the overall high level of performance. T he  
output amplifier achieves fast settling and high slew rates, pro-  
viding a full ±3 V signal at load currents up to 8 mA. When  
used in current output mode, the AD1851/AD1861 provides a  
±1 mA output signal. T he output amplifier is short circuit  
protected and can withstand indefinite shorts to ground.

l. AD1851 16-bit resolution provides 96 dB dynamic range.  
AD1861 18-bit resolution provides 108 dB dynamic range.  
2. No external components are required.  
3. Operates with ±5 V supplies.  
4. Space saving 16-pin SOIC and plastic DIP packages.  
5. 100 mW power dissipation.  
T he serial input interface consists of the clock, data and latch  
enable pins. T he serial 2s complement data word is clocked into  
the DAC, MSB first, by the external clock. T he latch enable  
signal transfers the input word from the internal serial input  
register to the parallel DAC input register. T he AD1851 input  
clock can support a 12.5 MHz data rate, while the AD1861 in-  
put clock can support a 13.5 MHz data rate. T his serial input  
port is compatible with second generation digital filter chips  
used in consumer audio products. T hese filters operate at over-  
sampling rates of 2ϫ, 4ϫ, 8ϫ and 16ϫ sampling frequencies.  
6. High input clock data rates and 1.5 µs settling time permits  
2ϫ, 4ϫ, 8ϫ and 16ϫ oversampling.  
7. ±3 V or ±1 mA output capability.  
8. T HD + Noise and SNR are 100% tested.  
9. Pin-compatible with AD1856 & AD1860 PCM audio DACs.
