Ceramic or tantalum types are recommended for use as bypass capacitors. The INA148 is a unity gain difference amplifier with a high common-mode input voltage range. A basic diagram of the circuit and pin connections is shown in Figure 1. The input impedances are unusually high for a difference amplifier and this should be considered when routing input signal traces on a PC board. Avoid placing digital signal traces near the difference amplifier’s input traces to minimize noise pickup. To achieve its high common-mode voltage range, the INA148 features a precision laser-trimmed thin-film resistor network with a 20:1 input voltage divider ratio. High input voltages are thereby reduced in amplitude, allowing the internal op amp to “see” input voltages that are within its linear operating range. A “Tee” network in the op amp feedback network places the amplifier in a gain of 20V/V, thus restoring the circuit’s overall gain to unity (1V/V). OPERATING VOLTAGE The INA148 is specified for ±15V and ±5V dual supplies and +5V single supplies. The INA148 can be operated with single or dual supplies with excellent performance. The INA148 is fully characterized for supply voltages from ±1.35V to ±18V and over temperatures of –55ºC to +125 ºC. Parameters that vary significantly with operating voltage, load conditions, or temperature are shown in the Typical Performance Curves section. External voltages can be summed into the amplifier’s output by using the Ref pin, making the differential amplifier a highly versatile design tool. Voltages on the Ref pin will also influence the INA148’s common-mode voltage range. In accordance with good engineering practice for linear integrated circuits, the INA148’s power-supply bypass +VS 0.1µF 7 – VIN 2 1MΩ 50kΩ 50kΩ + – VO = (VIN – VIN ) 2.7778kΩ 6 A1 + VIN 3 1MΩ 52.6316kΩ INA148 4 1 0.1µF –VS FIGURE 1. Basic Circuit Connections. ® INA148 8 VO THE GAIN EQUATION An internal on-chip resistor network sets the overall differential gain of the INA148 to precisely 1V/V. It’s output is accordance with the equation: + – V– ) + V VOUT = (VIN IN REF OFFSET TRIM The INA148 is laser-trimmed for low offset voltage and drift. Most applications will require no external offset adjustment. Since a voltage applied to the reference (Ref) pin (pin 1) will be summed directly into the amplifier’s output signal, this technique can be used to null the amplifier’s input offset voltage. Figure 2 shows an optional circuit for trimming the offset voltage. To maintain high common-mode rejection (CMR), the source impedance of any signal applied to the Ref terminal should be very low (≤5Ω). A source impedance of only 10Ω at the Ref pin will reduce the INA148’s CMR to approximately 74dB. High CMR can be restored if a resistor is added in series with the amplifier’s positive input terminal (pin 3). This resistor should be 19 times the source impedance that drives the Ref pin. For example, if the Ref pin sees a source impedance of 10Ω, a resistor of 190Ω should be added in series with pin 3. (1) COMMON-MODE RANGE The 20:1 input resistor ratio of the INA148 provides an input common-mode range that extends well beyond its power supply rails. The exact input voltage range depends on the amplifier’s power-supply voltage and the voltage applied to the Ref terminal (pin 1). Typical input voltage ranges at different power supply voltages can be found in the applications circuits section. +VS 7 2 – VIN 1MΩ 50kΩ 50kΩ + – VO = (VIN – VIN ) + VREF 2.7778kΩ 6 A1 190Ω + VIN 3 52.6316kΩ 1MΩ INA148 VREF 1 4 ±15mV Offset Trim Range, RTI VO +15V 10kΩ 10kΩ –VS 10Ω –15V FIGURE 2.

Preferred Offset Trim Circuit. ® 9 INA148 Preferably, the offset trim voltage applied to the Ref pin should be buffered with an amp such as an OPA237 (see Figure 3). In this case, the op amp output impedance is low enough that no external resistor is needed to maintain the INA148’s excellent CMR. Unless the shunt resistor is less than approximately 100Ω, an additional equal compensating resistor (RC) is recommended to maintain input balance and high CMR. Source impedances (or shunts) greater than 5kΩ are not recommended, even if they are “perfectly” compensated. This is because the internal resistor network is laser-trimmed for accurate voltage divider ratios, but not necessarily to absolute values. Input resistors are shown as 1MΩ, however, this is only their nominal value. INPUT IMPEDANCE The input resistor network determines the impedance of each of the INA148’s inputs. It is approximately 1MΩ. Unlike an instrumentation amplifier, signal source impedances at the two input terminals must be nearly equal to maintain good common-mode rejection. In practice, the input resistors’ absolute values may vary by as much as 30 percent. The two input resistors match to about 5 percent, so adding compensating resistors greater than 5kΩ can cause a serious mismatch in the resulting resistor network voltage divider ratios, thus degrading CMR. A mismatch between the two inputs’ source impedances will cause a differential amplifier’s common-mode rejection to be degraded. With a source impedance imbalance of only 500Ω, CMR can fall to approximately 66dB. Attempts to extend the INA148 input voltage range by adding external resistors is not recommended for the reasons just described in the last paragraph. CMR will suffer a serious degradation unless the resistors are carefully trimmed for CMR and gain. This is an iterative adjustment and can be tedious and time consuming. Figure 4 shows a common application—measuring power supply current through a shunt resistor (RS). A shunt resistor creates an unbalanced source resistance condition that can degrade a differential amplifier’s common mode rejection. +15V 7 LOAD 2 1MΩ 50kΩ 50kΩ VO = IL • RS IL 2.7778kΩ 6 A1 RS RC 3 VO 52.6316kΩ 1MΩ INA148 VCM 4 200V 1 –15V Make RC = RS if RS ≥ 100Ω FIGURE 4.

To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information published by TI regarding third-party products or services does not constitute a license from TI 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 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. Reproduction of this information with alteration is an unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
