LOW VOLTAGE HEADPHONE AMPLIFIERS
Figure 49 shows a stereo headphone output amplifier for the
AD1849 16-bit SOUNDPORT stereo codec device.1 The
pseudo-reference voltage is derived from the common-mode
voltage generated internally by the AD1849, thus providing a
convenient bias for the headphone output amplifiers.

LOW NOISE MICROPHONE AMPLIFIER FOR
MULTIMEDIA
The OPx13 family is ideally suited as a low noise microphone
preamp for low voltage audio applications. Figure 50 shows a
gain of 100 stereo preamp for the AD1849 16-bit SOUNDPORT
stereo codec chip. The common-mode output buffer serves as a
phantom power driver for the microphones.

PRECISION VOLTAGE COMPARATOR
With its PNP inputs and 0 V common-mode capability, the
OPx13 family can make useful voltage comparators. There is
only a slight penalty in speed in comparison to IC comparators.
However, the significant advantage is its voltage accuracy. For
example, VOS can be a few hundred microvolts or less, combined
with CMRR and PSRR exceeding 100 dB, while operating from
a 5 V supply. Standard comparators like the 111/311 family
operate on 5 V, but not with common mode at ground, nor with
offset below 3 mV. Indeed, no commercially available single-
supply comparator has a VOS less than 200 μV.
