DESCRIPTION

The DRV134 and DRV135 are differential output ampli-

fiers 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 resis-

tors. They are fully specified for high performance audio

applications and have excellent ac specifications, in-

cluding 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 sur-

face-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.

APPLICATIONS INFORMATION resistors. 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.
PAGE 9
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.
PAGE 10
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.
