Definition of Specifications–AD1866

TO TAL H ARMO NIC D ISTO RTIO N + NO ISE

T otal harmonic distortion plus noise (T HD+N) is defined as

the ratio of the square root of the sum of the squares of the am-

plitudes of the harmonics and noise to the amplitude of the fun-

damental input frequency. It is usually expressed in percent (%)

or decibels (dB).

FUNCTIO NAL D ESCRIP TIO N

T he AD1866 is a complete, monolithic dual 16-bit digital audio

DAC which runs off a single +5 volt supply. As shown in the

block diagram, each channel contains a voltage reference, a

16-bit serial-to-parallel input register, a 16-bit input latch, a

16-bit DAC, and an output amplifier.

T he voltage reference section provides a reference voltage and a

false ground voltage for each channel. T he low noise bandgap

circuits produce reference voltages that are unaffected by

changes in temperature, time, and power supply.

D -RANGE D ISTO RTIO N (EIAJ SP ECIFICATIO N)

D-Range distortion is the ratio of the amplitude of the signal at

an amplitude of –60 dB to the amplitude of the distortion plus

noise. In this case, an A-weight filter is used. T he value speci-

fied for D-range performance is the ratio measured plus 60 dB.

T he input registers are fabricated with CMOS logic gates.

T hese gates allow high switching speeds and low power con-

sumption, contributing to the fast digital timing, the low glitch

and low power dissipation of the AD1866.

SIGNAL-TO -NO ISE RATIO

T he signal-to-noise ratio is defined as the ratio of the amplitude

of the output when a full-scale output is present to the ampli-

tude of the output with no signal present. It is expressed in

decibels (dB) and measured using an A-weight filter.

GAIN LINEARITY

16-BIT

SERIAL

Gain linearity is a measure of the deviation of the actual output

amplitude from the ideal output amplitude. It is determined by

measuring the amplitude of the output signal as the amplitude

of that output signal is digitally reduced to a lower level. A per-

fect D/A converter exhibits no difference between the ideal and

actual amplitudes. Gain linearity is expressed in decibels (dB).

DGND

Midscale error, or bipolar zero error, is the deviation of the ac-

tual analog output from a voltage at the bias pin when the twos

complement input code representing midscale is loaded in the

DAC. Midscale error is expressed in mV.

DAC

AD1866 Functional Block Diagram

T he 16-bit DAC uses a combination of segmentation and R-2R

architecture to achieve good integral and differential linearity.

T he resistors which form the ladder structure are fabricated

with silicon-chromium thin film. Laser trimming of these resis-

tors further reduces linearity error, resulting in low output

distortion.

T he output amplifier uses both MOS and bipolar devices and

incorporates an NPN class A output stage. It is designed to pro-

duce high slew rate, low noise, low distortion, and optimal fre-

quency response.
