Its current-feedback circuitry achieves very wide bandwidth and excellent dynamic response. It is ideal for low-level audio signals such as balanced low-impedance microphones. The INA103 provides near-theoretical limit noise performance for 200Ω source impedances. Many industrial applications also benefit from its low noise and wide bandwidth. The INA103 is available in 16-pin plastic DIP and SOL-16 surface-mount packages. Commercial and Industrial temperature range models are available. Unique distortion cancellation circuitry reduces distortion to extremely low levels, even in high gain. Its balanced input, low noise and low distortion provide superior performance compared to transformer-coupled microphone amplifiers used in professional audio equipment. The INA103’s wide supply voltage (±9 to ±25V) and high output current drive allow its use in high-level audio stages as well. A copper lead frame in the plastic DIP assures excellent thermal performance. –Gain Drive 12 –Input 16 –Gain Sense 15 Offset Offset Null Null 3 4 6kΩ + A1 – 3kΩ 6kΩ 11 Sense –RG 13 – 60.6Ω G = 100 14 +RG 6 +Gain Sense 2 +Input 1 + 3kΩ 6kΩ – A3 10 Output 7 Ref 6kΩ A2 + 5 9 8 +Gain Drive V+ V– International Airport Industrial Park • Mailing Address: PO Box 11400, Tucson, AZ 85734 • Street Address: 6730 S.

Although not shown in other figures, this network can be used, if needed, with all applications shown. Figure 1 shows the basic connections required for operation. Power supplies should be bypassed with 1µF tantalum capacitors near the device pins. The output Sense (pin 11) and output Reference (pin 7) should be low impedance connections. Resistance of a few ohms in series with these connections will degrade the common-mode rejection of the amplifier. To avoid oscillations, make short, direct connection to the gain set resistor and gain sense connections. Avoid running output signals near these sensitive input nodes. GAIN SELECTION Gains of 1 or 100V/V can be set without external resistors. For G = 1V/V (unity gain) leave pin 14 open (no connection)—see Figure 4. For G = 100V/V, connect pin 14 to pin 6—see Figure 5. Gain can also be accurately set with a single external resistor as shown in Figure 1. The two internal feedback resistors are laser-trimmed to 3kΩ within approximately ±0.1%. The temperature coefficient of these resistors is approximately 50ppm/˚C. Gain using an external RG resistor is— 6kΩ G=1+ RG INPUT CONSIDERATIONS Certain source impedances can cause the INA103 to oscillate. This depends on circuit layout and source or cable characteristics connected to the input. An input network consisting of a small inductor and resistor (Figure 2) can greatly reduce the tendancy to oscillate.

Offset voltage can be trimmed with the optional circuit shown in Figure 3. This offset trim circuit primarily adjusts the output stage offset, but also has a small effect on input stage offset. For a 1mV adjustment of the output voltage, the input stage offset is adjusted approximately 1µV. Use this adjustment to null the INA103’s offset voltage with zero differential input voltage. Do not use this adjustment to null offset produced by a sensor, or offset produced by subsequent stages, since this will increase temperature drift. FIGURE 1. Basic Circuit Configuration. Accuracy and TCR of the external RG will also contribute to gain error and temperature drift. These effects can be directly inferred from the gain equation. Connections available on A1 and A2 allow external resistors to be substituted for the internal 3kΩ feedback resistors. A precision resistor network can be used for very accurate and stable gains. To preserve the low noise of the INA103, the value of external feedback resistors should be kept low. Increasing the feedback resistors to 20kΩ would increase noise of the INA103 to approximately 1.5nV/√Hz. Due to the current-feedback input circuitry, bandwidth would also be reduced. To offset the output voltage without affecting drift, use the circuit shown in Figure 4. The voltage applied to pin 7 is summed at the output. The op amp connected as a buffer provides a low impedance at pin 7 to assure good commonmode rejection. Figure 5 shows a method to trim offset voltage in ACcoupled applications. A nearly constant and equal input bias current of approximately 2.5µA flows into both input terminals. A variable input trim voltage is created by adjusting the balance of the two input bias return resistances through which the input bias currents must flow. NOISE PERFORMANCE The INA103 provides very low noise with low source impedance. Its 1nV/√Hz voltage noise delivers near theoretical noise performance with a source impedance of 200Ω. Relatively high input stage current is used to achieve this low noise. This results in relatively high input bias current and input current noise. As a result, the INA103 may not provide best noise performance with source impedances greater than 10kΩ. For source impedance greater than 10kΩ, consider the INA114 (excellent for precise DC applications), or the INA111 FET-input IA for high speed applications. V– 10kΩ 16 6kΩ G = 1 + —– RG 3 15 4 13 ∆V IN RG OFFSET ADJUSTMENT Offset voltage of the INA103 has two components: input stage offset voltage is produced by A1 and A2; and, output stage offset is produced by A3. Both input and output stage offset are laser trimmed and may not need adjustment in many applications. 14 11 10 INA103 VOUT 7 6 2 1 Offset Adjust Range = ±250mV. RTI FIGURE 3. Offset Adjustment Circuit. ® 9 INA103 OUTPUT SENSE An output sense terminal allows greater gain accuracy in driving the load. By connecting the sense connection at the load, I•R voltage loss to the load is included inside the feedback loop. Current drive can be increased by connecting a current booster inside the feedback loop as shown in Figure 11. Figure 6 shows an active control loop that adjusts the output offset voltage to zero. A2, R, and C form an integrator that produces an offsetting voltage applied to one input of the INA103. This produces a –6dB/octave low frequency rolloff like the capacitor input coupling in Figure 5. COMMON-MODE INPUT RANGE For proper operation, the combined differential input signal and common-mode input voltage must not cause the input amplifiers to exceed their output swing limits. The linear input range is shown in the typical performance curve “Maximum Common-Mode Voltage vs Output Voltage.” For a given total gain, the input common-mode range can be increased by reducing the input stage gain and increasing the output stage gain with the circuit shown in Figure 7.

Here, the amplifier’s input is driven beyond its linear common-mode range, forcing the output of the amplifier into the supply rails. The output then “folds back”, i.e., a more positive input voltage now causes the output of the amplifier to go negative. The INA103 has protection circuitry to prevent fold-back, and as shown in (b), limits cleanly. FIGURE 9. INA103 Overload Condition Performance.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
