® DRV134 DRV135 DRV 134 DRV 134 DRV 135 AUDIO BALANCED LINE DRIVERS FEATURES DESCRIPTION ● ● ● ● ● ● ● ● ● 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). 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. The DRV134 is available in 8-pin DIP and SOL-16 surface-mount packages. The DRV135 comes in a space-saving SO-8 surface-mount package. Both are specified for operation over the extended industrial temperature range, –40°C to +85°C and operate from –55°C to +125°C.

Characterized by low differential-mode output impedance (50Ω) and high common-mode output impedance (1.6kΩ), 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. The DRV134 (and DRV135 in SO-8 package) converts a single-ended, ground-referenced input to a floating differential output with +6dB gain (G = 2). Figure 1 shows the basic connections required for operation. Decoupling capacitors placed close to the device pins are strongly recommended in applications with noisy or high impedance power supplies.

Complete Audio Driver/Receiver Circuit. ® DRV134, 135 –VO 8 VO 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 measurement limit of commonly used test equipment. Furthermore, 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. Furthermore, 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 receiver. 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. +18V 1µF VIN The DRV134 has excellent distortion characteristics. As shown in the distortion data provided in the typical performance 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 performance. Measurements were taken with an Audio Precision System One (with the internal 80kHz noise filter) using the THD test circuit shown in Figure 3. 6 4 7 8 VOD DRV134 Gnd 1 2 5 3 300Ω(1) +VO 300Ω(1) –VO 600Ω 1µF VCM = 10Vp-p –18V OCMR = –20 Log ( VOD VCM ) at f = 1kHz, VOD = (+VO) – (–VO) NOTE: (1) Matched to 0.1%.

FIGURE 3. Distortion Test Circuit. ® 9 DRV134, 135 SIGNAL BALANCE RATIO 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 minimize SBR errors. In an application, SBR also depends on the balance of the load network. For best rejection of line noise and hum differential mode operation is recommended. However, single-ended performance is adequate for many applications. In general singleended performance is comparable to differential mode (see THD+N typical performance curves), but the commonmode and noise rejection inherent in balanced-pair systems is lost. 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. +18V 1µF VIN = 10Vp-p 6 4 +VO 7 THERMAL PERFORMANCE The DRV134 and DRV135 have robust output drive capability and excellent performance over temperature. In most applications there is no significant difference between the DIP, SOL-16, and SO-8 packages. However, for applications with extreme temperature and load conditions, the SOL-16 (DRV134UA) or DIP (DRV134PA) packages are recommended. Under these conditions, such as loads greater than 600Ω or very long cables, performance may be degraded in the SO-8 (DRV135UA) package. 300Ω(1) 8 DRV134 Gnd 1 2 5 3 300Ω(1) VOUT –VO 600Ω 1µF –18V SBR = –20 Log ( VOUT VIN ) at f = 1kHz LAYOUT CONSIDERATIONS 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 bypassing, the suggestions below should be followed to achieve optimal OCMR and noise rejection. NOTE: (1) Matched to 0.1%. 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+ VOUT = 2VIN 6 VIN • Shielded twisted-pair cable is recommended for all applications. Physical balance in signal wiring should be maintained. Capacitive differences due to varying wire lengths may result in unequal noise pickup between the pair and degrade OCMR. Follow industry practices for proper system grounding of the cables. 7 4 8 600Ω DRV134 1 2 3 5 G = +6dB V– FIGURE 6.
