AUDIO BALANCED LINE DRIVERS  
DESCRIPTION  
FEATURES  
The DRV134 and DRV135 are differential output  
amplifiers that convert a single-ended input to a  
balanced output pair. These balanced audio drivers  
consist of high performance op amps with on-chip  
precision resistors. They are fully specified for high  
performance audio applications and have excellent  
ac specifications, including low distortion (0.0005%  
at 1kHz) and high slew rate (15V/µs).  
BALANCED OUTPUT  
LOW DISTORTION: 0.0005% at f = 1kHz  
WIDE OUTPUT SWING: 17Vrms into 600Ω  
HIGH CAPACITIVE LOAD DRIVE  
HIGH SLEW RATE: 15V/µs  
WIDE SUPPLY RANGE: ±4.5V to ±18V  
LOW QUIESCENT CURRENT: ±5.2mA  
8-PIN DIP, SO-8, AND SOL-16 PACKAGES  
The on-chip resistors are laser-trimmed for accurate  
gain and optimum output common-mode rejection. Wide  
output voltage swing and high output drive capability  
allow use in a wide variety of demanding applications.  
They easily drive the large capacitive loads associated  
with long audio cables. Used in combination with the  
INA134 or INA137 differential receivers, they offer a  
complete solution for transmitting analog audio signals  
without degradation.

DISCHARGE SENSITIVITY  
This integrated circuit can be damaged by ESD. Burr-Brown  
recommends that all integrated circuits be handled with ap-  
propriate precautions. Failure to observe proper handling and  
installation procedures can cause damage.  
NOTE: (1) Stresses above these ratings may cause permanent damage.  
Exposure to absolute maximum conditions for extended periods may affect  
device reliability.  
ESD damage can range from subtle performance degradation  
to complete device failure. Precision integrated circuits may  
be more susceptible to damage because very small parametric  
changes could cause the device not to meet its published  
specifications.

resistors. Characterized by low differential-mode output  
impedance (50) and high common-mode output imped-  
ance (1.6k), the DRV134 is ideal for audio applications.  
Normally, +VO is connected to +Sense, –VO is connected to  
–Sense, and the outputs are taken from these junctions as  
shown in Figure 1. For applications with large dc cable  
offset errors, a 10µF electrolytic nonpolarized blocking  
capacitor at each sense pin is recommended as shown in  
Figure 2.  
APPLICATIONS INFORMATION  
The DRV134 (and DRV135 in SO-8 package) converts a  
single-ended, ground-referenced input to a floating differ-  
ential output with +6dB gain (G = 2). Figure 1 shows the  
basic connections required for operation. Decoupling ca-  
pacitors placed close to the device pins are strongly recom-  
mended in applications with noisy or high impedance power  
supplies.  
The DRV134 consists of an input inverter driving a cross-  
coupled differential output stage with 50series output

DRV134, 135  
Excellent internal design and layout techniques provide low  
signal distortion, high output level (+27dBu), and a low  
noise floor (–98dBu). Laser trimming of thin film resistors  
assures excellent output common-mode rejection (OCMR)  
and signal balance ratio (SBR). In addition, low dc voltage  
offset reduces errors and minimizes load currents.  
Up to approximately 10kHz, distortion is below the mea-  
surement limit of commonly used test equipment. Further-  
more, distortion remains relatively constant over the wide  
output voltage swing range (approximately 2.5V from the  
positive supply and 1.5V from the negative supply). A  
special output stage topology yields a design with minimum  
distortion variation from lot-to-lot and unit-to-unit. Further-  
more, the small and large signal transient response curves  
demonstrate the DRV134’s stability under load.  
For best system performance, it is recommended that a high  
input-impedance difference amplifier be used as the re-  
ceiver. Used with the INA134 (G = 0dB) or the INA137 (G  
= ±6dB) differential line receivers, the DRV134 forms a  
complete solution for driving and receiving audio signals,  
replacing input and output coupling transformers commonly  
used in professional audio systems (Figure 2). When used  
with the INA137 (G = –6dB) overall system gain is unity.  
OUTPUT COMMON-MODE REJECTION  
Output common-mode rejection (OCMR) is defined as the  
change in differential output voltage due to a change in  
output common-mode voltage. When measuring OCMR,  
VIN is grounded and a common-mode voltage, VCM, is  
applied to the output as shown in Figure 4. Ideally no  
differential mode signal (VOD) should appear. However, a  
small mode-conversion effect causes an error signal whose  
magnitude is quantified by OCMR.  
AUDIO PERFORMANCE  
The DRV134 was designed for enhanced ac performance.  
Very low distortion, low noise, and wide bandwidth provide  
superior performance in high quality audio applications.  
Laser-trimmed matched resistors provide optimum output  
common-mode rejection (typically 68dB), especially when  
compared to circuits implemented with op amps and discrete  
precision resistors. In addition, high slew rate (15V/µs) and  
fast settling time (2.5µs to 0.01%) ensure excellent dynamic  
response.

The DRV134 has excellent distortion characteristics. As  
shown in the distortion data provided in the typical perfor-  
mance curves, THD+Noise is below 0.003% throughout the  
audio frequency range under various output conditions. Both  
differential and single-ended modes of operation are shown.  
In addition, the optional 10µF blocking capacitors used to  
minimize VOCM errors have virtually no effect on perfor-  
mance. Measurements were taken with an Audio Precision  
System One (with the internal 80kHz noise filter) using the  
THD test circuit shown in Figure 3.

SIGNAL BALANCE RATIO  
For best rejection of line noise and hum differential mode  
operation is recommended. However, single-ended perfor-  
mance is adequate for many applications. In general single-  
ended performance is comparable to differential mode (see  
THD+N typical performance curves), but the common-  
mode and noise rejection inherent in balanced-pair systems  
is lost.  
Signal balance ratio (SBR) measures the symmetry of the  
output signals under loaded conditions. To measure SBR an  
input signal is applied and the outputs are summed as shown  
in Figure 5. VOUT should be zero since each output ideally  
is exactly equal and opposite. However, an error signal  
results from any imbalance in the outputs. This error is  
quantified by SBR. The impedances of the DRV134’s out  
put stages are closely matched by laser trimming to mini-  
mize SBR errors. In an application, SBR also depends on the  
balance of the load network.  
CABLE  
The DRV134 is capable of driving large signals into 600Ω  
loads over long cables. Low impedance shielded audio  
cables such as the standard Belden 8451 or 9452 (or similar)  
are recommended, especially in applications where long  
cable lengths are required.

The DRV134 and DRV135 have robust output drive capa-  
bility and excellent performance over temperature. In most  
applications there is no significant difference between the  
DIP, SOL-16, and SO-8 packages. However, for applica-  
tions with extreme temperature and load conditions, the  
SOL-16 (DRV134UA) or DIP (DRV134PA) packages are  
recommended. Under these conditions, such as loads greater  
than 600or very long cables, performance may be de-  
graded in the SO-8 (DRV135UA) package.

LAYOUT CONSIDERATIONS  
NOTE: (1) Matched to 0.1%.  
A driver/receiver balanced-pair (such as the DRV134 and  
INA137) rejects the voltage differences between the grounds  
at each end of the cable, which can be caused by ground  
currents, supply variations, etc. In addition to proper bypass-  
ing, the suggestions below should be followed to achieve  
optimal OCMR and noise rejection.  
FIGURE 5. Signal Balance Ratio Test Circuit.  
SINGLE-ENDED OPERATION  
The DRV134 can be operated in single-ended mode without  
degrading output drive capability. Single-ended operation  
requires that the unused side of the output pair be grounded  
(both the VO and Sense pins) to a low impedance return path.  
Gain remains +6dB. Grounding the negative outputs as  
shown in Figure 6 results in a noninverted output signal  
(G = +2) while grounding the positive outputs gives an  
inverted output signal (G = –2).  
• The DRV134 input should be driven by a low impedance  
source such as an op amp or buffer.  
• As is the case for any single-ended system, the source’s  
common should be connected as close as possible to the  
DRV134’s ground. Any ground offset errors in the source  
will degrade system performance.  
• Symmetry on the outputs should be maintained.  
V+  
• Shielded twisted-pair cable is recommended for all appli-  
cations. Physical balance in signal wiring should be main-  
tained. Capacitive differences due to varying wire lengths  
may result in unequal noise pickup between the pair and  
degrade OCMR. Follow industry practices for proper sys-  
tem grounding of the cables.
