Decoupling capacitors are strongly recommended in applications with noisy or high impedance power supplies. The capacitors should be placed close to the device pins as shown in Figure 1. All circuitry is completely independent in the dual version assuring lowest crosstalk and normal behavior when one amplifier is overdriven or short-circuited. 1µF 1µF 7 4 INA134 –In V2 As shown in Figure 1, the differential input signal is connected to pins 2 and 3. The source impedances connected to the inputs must be nearly equal to assure good commonmode rejection. A 10Ω mismatch in source impedance will degrade the common-mode rejection of a typical device to approximately 74dB. If the source has a known impedance mismatch, an additional resistor in series with the opposite input can be used to preserve good common-mode rejection. 2 R2 25kΩ R1 25kΩ 5 6 VOUT = V3 – V2 +In 3 V3 Do not interchange pins 1 and 3 or pins 2 and 5, even though nominal resistor values are equal. These resistors are laser trimmed for precise resistor ratios to achieve accurate gain and highest CMR. Interchanging these pins would not provide specified performance. R4 25kΩ R3 25kΩ 1 FIGURE 1. Precision Difference Amplifier (Basic Power Supply and Signal Connections). INA134 AUDIO PERFORMANCE The INA134 and INA2134 were 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 common-mode rejection (typically 90dB), especially when compared to circuits implemented with an op amp and discrete precision resistors. In addition, high slew rate (14V/µs) and fast settling time (3µs to 0.01%) ensure good dynamic performance. R1 R2 5 6 10Ω V3 3 VO R3 R4 The INA134 and INA2134 have excellent distortion characteristics. THD+Noise is below 0.002% throughout the audio frequency range. Up to approximately 10kHz distortion is below the measurement limit of commonly used test equipment. Furthermore, distortion remains relatively flat over its wide output voltage swing range (approximately 1.7V from either supply). +15V VO = V3 – V2 Offset Adjustment Range = ±300µV 1 499kΩ 100kΩ 10Ω –15V FIGURE 2. Offset Adjustment. OFFSET VOLTAGE TRIM The INA134 and INA2134 are laser trimmed for low offset voltage and drift. Most applications require no external offset adjustment. Figure 2 shows an optional circuit for trimming the output offset voltage. The output is referred to the output reference terminal (pin 1), which is normally grounded. A voltage applied to the Ref terminal will be summed with the output signal. This can be used to null offset voltage as shown in Figure 2. The source impedance of a signal applied to the Ref terminal should be less than 10Ω to maintain good common-mode rejection. ® INA134/2134 2 V2 8 INA134 5 2 INA134 V1 6 1 V1 –In V0 = V1 + V2 1/2 OPA2134 5 2 R2 V2 3 6 R1 V2 INA134 –In 2 V0 0utput R2 FIGURE 3.
