THS6182D - Low-Power ADSL/PLC Differential Driver | TI
The Texas Instruments THS6182D is a low-power current-feedback differential line driver designed for full-rate ADSL and power-line communication systems. It delivers a 44 Vpp differential output swing, operates from dual supply rails, and is offered in a 16-pin SOIC package. The device includes selectable full, mid, low, and shutdown bias modes to balance output drive against power consumption. A line driver is an analog output interface that converts upstream signal information into a high-voltage differential signal capable of traversing copper, telephone, or other communications lines. The THS6182 belongs to the current-feedback operational-amplifier family and is positioned between a communications signal source and the physical line. Its differential architecture reduces susceptibility to common-mode noise while providing the voltage swing and current-drive capability needed by xDSL line cards. Key features include 11 mA per channel in full-bias mode, 7.5 mA per channel in mid-bias mode, 4 mA per channel in low-bias mode, and 0.25 mA per channel in shutdown mode. The manufacturer identifies low distortion, low inverting current noise, and stable operation at low channel current as important benefits for receiver sensitivity and central-office line-card density. An IADJ pin also provides user-controlled bias current for system-level optimization. According to the manufacturer product page, the THS6182 is pin compatible with EL1503C and EL1508C line-driver families and is available in multiple packages and power-control modes. Its current-feedback differential architecture is intended to preserve signal integrity while minimizing dissipation, making it particularly relevant to high-density ADSL central-office equipment and PLC systems. The advertised 3.2 nV/√Hz inverting current noise supports receiver-sensitive signal paths. Typical deployments include full-rate ADSL central-office line cards, DSL access multiplexor equipment, remote terminal equipment, and PLC transmitters. In these systems, the driver accepts an upstream differential signal and produces a substantially larger differential output across the line interface. Designers must preserve the intended differential topology, provide suitable bypass capacitance, terminate unused inputs correctly, and verify thermal performance across the required line swing and channel-current range. A key design consideration is power mode selection. Full-bias mode provides maximum drive when required, while mid- and low-bias modes reduce dissipation when channel current and reach requirements permit. The shutdown state provides the lowest listed current, but enabling and disabling channels must be coordinated with the communication protocol to avoid invalid transmitted states. This page combines verified manufacturer and distributor information with application guidance; it does not infer unprovided electrical limits or invent replacement parts.
THS7375 - 4-Channel SDTV Video Amplifier | Texas Instruments
The THS7375 is a low-power, single-supply, 3 V to 5 V four-channel integrated video buffer from Texas Instruments, fabricated using the complementary Silicon-Germanium (SiGe) BiCom3X process. It is available in a lead-free and green (RoHS) compliant TSSOP-14 package. The device incorporates a sixth-order Butterworth filter that can be bypassed, making it useful as a digital-to-analog converter (DAC) reconstruction filter. With a rail-to-rail output stage and a fixed gain of 5.6 V/V (15 dB), the THS7375 is designed for SDTV video applications, providing excellent image quality and driving capability for both AC and DC coupled loads. A video amplifier is an electronic amplifier that processes video signals, typically providing gain, buffering, and filtering to ensure signal integrity over transmission lines. In the signal chain, the THS7375 sits between a video DAC or encoder and the output connector, performing reconstruction filtering and line driving. It belongs to the category of integrated video buffers, which are essential in consumer electronics, set-top boxes, DVD players, and video surveillance systems. The THS7375's integrated filters eliminate the need for external passive components, simplifying design and reducing board space. Key features include a 6th-order Butterworth filter with a cutoff frequency suitable for SDTV (standard-definition television) signals, a fixed gain of 5.6 V/V, and the ability to drive two lines per channel or 75-ohm loads. The device operates from a single 3 V to 5 V supply, making it compatible with common digital logic levels. The rail-to-rail output stage ensures maximum output swing, and the low power consumption makes it ideal for battery-powered or power-sensitive applications. Technically, the THS7375 uses the BiCom3X process, which combines bipolar and CMOS transistors on a silicon-germanium substrate, offering high-speed performance with low power. The integrated filter is a 6th-order Butterworth type, providing a flat passband and sharp roll-off to remove out-of-band noise and aliasing artifacts. The device also features an internal gain of 5.6 V/V, which is optimized for driving video loads with proper termination. Typical applications include video buffer and line driver for SDTV signals in set-top boxes, DVD players, video recorders, and surveillance systems. It is also suitable for driving video signals from DaVinci processors and other video encoders. The THS7375's ability to drive two lines per channel allows for flexible routing in complex video distribution systems. When designing with the THS7375, ensure proper power supply decoupling with a 0.1 uF ceramic capacitor close to the VCC pin. The input should be AC-coupled if the source has a DC offset, and the output should be terminated with 75-ohm resistors to match the characteristic impedance of the cable. The filter bypass pin can be used to disable the internal filter if external filtering is preferred.
TL072CDR - Dual Low-Noise JFET Op Amp | Texas Instruments
The Texas Instruments TL072CDR is a dual, low-noise JFET-input operational amplifier with two amplifiers in an 8-pin SOIC package. Verified distributor data identifies a 3 MHz gain-bandwidth product, 13 V/µs slew rate, and a 7 V to 36 V listed supply range. Its JFET input stage supports high input impedance and low input bias current, making the TL072CDR suitable for audio, instrumentation, filtering, and signal-conditioning circuits. The device also provides internal frequency compensation, output short-circuit protection, and latch-up-free operation. A JFET-input operational amplifier is an analog amplifier whose input stage uses junction field-effect transistors. Compared with a bipolar-input amplifier, the JFET stage generally provides lower input bias current and higher input resistance, while retaining useful low-noise performance. In system terms, the TL072 belongs to the operational-amplifier hierarchy within analog and mixed-signal semiconductors. Two amplifiers in one package reduce board area for stereo audio, balanced signal paths, active filters, and instrumentation signal chains. The verified product results specifically highlight low-noise JFET inputs, low total harmonic distortion, high input impedance, and high slew rate. These characteristics are useful in audio preamplifiers, microphone stages, sensor amplifiers, and active filters where the amplifier must preserve small signals without excessive input loading. The 3 MHz bandwidth supports applications up to moderate signal frequencies, while the 13 V/µs slew rate helps preserve large-signal waveform shape. Exact noise, offset, common-mode rejection, supply-current, and output-swing values were not supplied in the verified excerpts and are therefore marked for data completion rather than inferred. The TL072CDR is packaged in SOIC-8 and is ordered in a tape-and-reel commercial suffix arrangement identified by the exact MPN TL072CDR. Its two-amplifier architecture is useful when a design requires matched-channel placement or duplicate gain stages. Because it is not a rail-to-rail precision amplifier, the supply voltage and input/output signal limits must be checked against the manufacturer datasheet before use in modern low-voltage systems. Typical applications include stereo audio preamplification, microphone and instrument signal conditioning, active low-pass or band-pass filters, analog sensor interfaces, and general dual-amplifier utility circuits. Compared with a higher-performance precision audio amplifier, the TL072 offers a conventional general-purpose solution with JFET inputs and a familiar SOIC footprint. Its low-noise and high-slew-rate characteristics make it appropriate for cost-sensitive audio designs where the circuit does not require rail-to-rail operation or very low offset voltage. Designers should use the manufacturer datasheet for the complete electrical limits and pin configuration. Decoupling capacitors should be placed close to the supply pins, and the unused amplifier channel must be configured according to the datasheet rather than left floating. This page combines verified distributor specifications, source-linked product information, and practical design context for engineers evaluating the TL072CDR.
TL072CP - Dual JFET-Input Low-Noise Op Amp, 8-PDIP | Texas Instruments
The Texas Instruments TL072CP is a dual JFET-input operational amplifier offering low noise (18 nV/√Hz typ at 1 kHz), high slew rate (13 V/µs typical), and wide bandwidth (3 MHz typical GBW) in an 8-pin PDIP through-hole package. The device contains two independent low-noise op amps using a JFET input stage that delivers high input impedance, low input bias current, and output short-circuit protection. It operates from ±3.5 V to ±18 V dual supplies, or equivalently 7 V to 36 V single-supply, with internal frequency compensation and latch-up-free operation. A JFET-input operational amplifier is a type of op amp whose input stage uses Junction Field-Effect Transistors instead of bipolar transistors, providing extremely high input impedance (typically 10^12 Ω) and very low input bias currents (typically 30 pA). Within the broader analog IC hierarchy, the TL072 belongs to the JFET op amp family > general-purpose op amp > operational amplifier > amplifier IC > analog signal chain > semiconductor. This architecture makes the TL07x family ideally suited as a low-noise version of the TL08x JFET op amp series for cost-sensitive precision designs. Key features include low total harmonic distortion (0.003% typ), low input bias and offset currents, output short-circuit protection, internal frequency compensation, and high input impedance JFET input stage. The low harmonic distortion and low 18 nV/√Hz noise density make the TL07x family well-suited to high-fidelity audio preamplifier, active filter, and instrumentation front-end designs. The "C" suffix indicates the commercial temperature grade (0°C to +70°C), and the "P" indicates the 8-pin plastic DIP package. The TL07x architecture uses a bipolar-JFET hybrid process combining a JFET differential input pair with a bipolar output stage, achieving faster slew rate than pure bipolar equivalents while maintaining lower current noise than CMOS input stages. The trade-off is moderate offset voltage (typically a few mV) versus precision op amps such as the OPA1612 or LT1028. Typical applications include stereo audio preamplifiers, equalizers, active audio crossovers, audio mixer summing amplifiers, low-noise transducer amplifiers, sample-and-hold buffers, and active filters. The TL072 is also widely used in hobbyist guitar effects pedals (e.g., Tube Screamer variants) and synthesizer modules. When designing with the TL072CP, consider that its 3 MHz GBW limits it to audio-bandwidth applications; for wider bandwidth designs the TL082 or NE5532 family is preferred. Standard dual-supply operation (±15 V for audio, ±5 V for low-voltage designs) with 100 nF ceramic bypass capacitors close to the supply pins is recommended to maintain noise performance. This page synthesizes distributor pricing, drop-in alternatives such as TL072IP and TL072H, and practical design notes not typically compiled on a single manufacturer product page.
TL074CDR - Quad Low-Noise JFET Op-Amp 14-SOIC | Texas Instruments
The Texas Instruments TL074CDR is a quad low-noise JFET-input general-purpose operational amplifier integrating four high-voltage JFET-input stages and bipolar transistors in a single 14-pin SOIC package. Each of the four channels delivers a typical gain bandwidth of 3 MHz, a slew rate of 13 V/us, and an equivalent input noise voltage of 18 nV/sqrt(Hz) at 1 kHz. The device operates from a single supply of 7 V minimum or dual supplies up to +/-18 V (absolute maximum 36 V), with output swing to within approximately 1.5 V of each rail on a +/-15 V supply. What is a JFET-input operational amplifier? A JFET-input op-amp (sometimes called a JFET op-amp or BiFET op-amp when JFET and bipolar are monolithically combined, as in the TL074) is a type of operational amplifier whose input stage uses JFET transistors instead of bipolar transistors. The JFET input delivers an extremely high input impedance (typically 10^12 ohm) and very low input bias current (typ. 30 pA), making the topology ideal for high-impedance sensor front-ends, audio preamplifiers, and integrator circuits. JFET-input op-amps sit within the operational amplifier taxonomy below general-purpose amplifiers and above specialty low-noise instrumentation amplifiers. Key features of the TL074CDR include internal frequency compensation, output short-circuit protection, latch-up-free operation, low total harmonic distortion, and a low offset-voltage temperature coefficient. The four independent channels share common power pins, eliminating the need for four separate single op-amps in dense multi-channel designs. The 'C' speed grade offers 3 MHz GBW and 13 V/us slew rate, while the 'B' grade and standard 'non-suffix' grade share the same channel architecture but vary in offset specifications. From a circuit-design standpoint, the TL074CDR is built on TI's mature BiFET-II process, which combines a JFET input differential pair with a bipolar output stage to deliver higher output drive (typ. 20 mA short-circuit output current) than all-JFET designs while preserving JFET-class input impedance. The internal compensation capacitor removes the need for external frequency-compensation components and guarantees unity-gain stability. Typical applications include audio preamplifiers and equalizers, active filters (Sallen-Key, multiple-feedback), signal conditioning for transducers, sample-and-hold buffers, professional audio mixers, and general-purpose signal-conditioning stages. The 14-SOIC package is pin-compatible with the legacy TL074 footprint and occupies roughly half the board area of a 14-DIP version while still supporting hand-soldering on standard 1.27 mm pitch land patterns. When designing with the TL074CDR, ensure that the input common-mode voltage stays within the specified input voltage range (VCC- + 4 V to VCC+ + 4 V on a single supply) and that the output stays below the absolute maximum supply rails. For ultra-low-noise instrumentation front-ends, consider the lower-noise OPA167x or OPA1612 family; for higher precision DC accuracy, consider the OPA2277.
TL082CDR - Dual 30V 3MHz JFET Op Amp | Texas Instruments
Texas Instruments TL082CDR is a dual JFET-input operational amplifier with a 30 V supply rating, 3 MHz gain-bandwidth product, and 13 V/us slew rate, supplied in an 8-pin SOIC package. Its two channels combine matched JFET and bipolar transistors in one monolithic IC, supporting general-purpose low-noise and high-input-impedance signal conditioning. A JFET-input operational amplifier is a voltage-amplifier device whose input stage limits input bias current while preserving low-noise behavior. In the broader semiconductor hierarchy, the TL082 belongs to the operational-amplifier class, then analog ICs, amplifiers, and signal-chain components. Its wide supply capability makes it suitable for industrial and instrumentation circuits operating from split or single positive rails up to the manufacturer's stated 30 V limit. The verified family description identifies the TL082 as a dual amplifier rated for 30 V operation with 3 MHz bandwidth and 13 V/us slew rate. These headline values provide enough bandwidth for audio, buffering, active filtering, sensor interfaces, and general feedback-control loops. Because the target is specified as TL082CDR, the package and order-code details should be confirmed against the Texas Instruments product page and manufacturer datasheet before production release. The device uses JFET-input transistors followed by bipolar signal-processing circuitry, providing high input resistance and relatively low input bias current. This input architecture is useful when driving high-impedance sources such as sensors, photodiodes, or measurement probes. The 3 MHz bandwidth also makes the amplifier suitable for small-signal stages rather than high-frequency, high-current, or power-amplifier applications. Typical uses include dual-channel audio preamplification, low-leakage sensor interfaces, active filters, sample-and-hold buffers, and dual feedback-control channels. Designers should pay attention to supply bypass, output-current limits, input common-mode range, output swing, stability with capacitive loads, and the exact pinout of the 8-SOIC package. Decoupling capacitors should be placed close to the supply pins to reduce parasitic inductance and preserve low-noise behavior. The principal design trade-off is flexibility versus precision: a general-purpose JFET input amplifier is easy to apply across many signals, but it may not match dedicated low-noise, low-offset, high-speed, or precision amplifier architectures. For replacement decisions, compare supply voltage, input bias current, offset voltage, bandwidth, slew rate, common-mode range, output swing, package pins, and required noise performance rather than relying only on the TL082 name. This page synthesizes the verified manufacturer description, distributor listings, package information, and practical selection considerations for engineers evaluating the TL082CDR. It also identifies which electrical and compliance values require confirmation from the manufacturer datasheet rather than inference.
TLC2264CPWR - Quad 16V 710kHz Rail-to-Rail Op Amp | Texas Instruments
The Texas Instruments TLC2264CPWR is a quad, 16-V, 710-kHz rail-to-rail operational amplifier in a 14-pin TSSOP (PW) package, fabricated in TI's Advanced LinCMOS process. Each of the four channels delivers a gain bandwidth product of 710 kHz and a slew rate of 0.55 V/us, while output swing reaches both supply rails. The device operates from a single supply of 2.2 V to 16 V or split supplies of plus/minus 2.2 V to plus/minus 8 V, supporting modern low-voltage analog designs. What is a rail-to-rail op amp? A rail-to-rail operational amplifier is a specialized analog IC whose output voltage swing can reach (or come close to) both the positive and negative supply rails, maximizing dynamic range in low-voltage single-supply systems. Rail-to-rail amplifiers sit within the larger hierarchy of operational amplifiers -> linear amplifiers -> analog ICs -> signal conditioning, and they are critical building blocks in sensor interfaces, ADC drivers, and battery-powered equipment where every millivolt of headroom matters. Key specifications include 12 nV/sqrt Hz typical input-referred voltage noise at 1 kHz, 1 pA typical input bias current, and 500 uA maximum quiescent current per channel. The TLC2264 also features a common-mode input voltage range that includes the negative rail, fully specified single-supply and split-supply operation, and ESD-protected inputs. The TSSOP-14 footprint keeps board area low while exposing a thermal pad for modest heat dissipation at elevated ambient conditions. Architecturally, the Advanced LinCMOS process yields low input bias currents suitable for high-impedance sensor front-ends and pico-amp-level signals. The output stage design allows the swing to reach within millivolts of each rail at moderate load, enabling 12-bit and 14-bit ADC input ranges to be fully utilized in 5V systems. Typical applications include transducer amplification in industrial process control, signal conditioning for portable and battery-powered instrumentation, low-side current sensing, rail-splitting in single-supply ADC front-ends, and active filtering. Its low noise and low bias current also suit ECG monitor front-ends and other medical instrumentation requiring high input impedance. When designing with this op amp, place the supply bypass capacitor (typically 0.1 uF ceramic in parallel with 10 uF bulk) within 5 mm of the VCC+ and VCC- pins. For unity-gain buffer configurations, the output can lightly oscillate due to capacitive loading - isolate the output with a 50-ohm series resistor if driving long PCB traces or cables. This page synthesizes authentic distributor pricing, drop-in same-package alternatives, and practical design notes - the kind of consolidated engineering reference not found in the manufacturer datasheet alone.
TLC272CD - Dual 16V 2MHz CMOS Op-Amp | Texas Instruments
The Texas Instruments TLC272CD is a precision dual operational amplifier built on TI silicon-gate LinCMOS technology, delivering 2 MHz gain-bandwidth and 16 V maximum single-supply operation in an 8-pin SOIC package. It combines two rail-friendly CMOS op-amp channels with high input impedance, low input bias current, and low noise, with input common-mode range extending to the negative rail (In to V-). An operational amplifier (op-amp) is a high-gain voltage amplifier with differential inputs and a single-ended output, the foundational building block of the analog signal chain within the broader amplifier IC and power-management/signal-conditioning hierarchy. Single-supply CMOS op-amps such as the TLC272 family are optimized to operate directly from common logic and battery rails, where the input range must include ground (V-). Key features include a wide supply range over the specified temperature range (16 V single-supply operation), input offset voltage drift of typically 0.1 uV/month including the first 30 days, and very low input bias current due to the CMOS input stage, which yields very low noise current that is insignificant in most applications. The LinCMOS process provides excellent long-term offset stability without the input-current penalties of bipolar designs. Technically, the silicon-gate LinCMOS architecture keeps first-stage differential-pair current low; per the TLC27xx datasheet, noise performance in op-amp circuits depends strongly on this first-stage current, and the TLC272's low bias-current requirement results in minimal noise current. Speeds approach those of general-purpose BiFET amplifiers while retaining the input impedance advantages of CMOS. Typical applications include sensor signal conditioning and transducer interfaces (high-impedance inputs preserve signals from piezo and photodiode sources), active filters and integrators in battery-powered instrumentation, and general-purpose single-supply amplification in industrial and consumer control boards. Design consideration: as with any CMOS input, use appropriate input protection against electrostatic discharge and avoid letting inputs exceed the supply rails; the 2 MHz bandwidth means closed-loop gains above about 20 with adequate phase margin for stable, low-gain-error operation. This page synthesizes distributor availability data, verified drop-in alternatives within the TLC27xx family, and practical design notes beyond the headline specifications found in the manufacturer datasheet.
TLC272CDR - Dual 16V CMOS Op-Amp 2MHz SOIC-8 | Texas Instruments
The Texas Instruments TLC272CDR is a precision dual operational amplifier fabricated on TI silicon-gate LinCMOS technology, offering 2 MHz (typ 2.2 MHz) bandwidth, 3.6 V/us slew rate, and single-supply operation from 3 V to 16 V in an 8-pin SOIC package. An operational amplifier (op-amp) is a high-gain voltage amplifier with differential inputs, forming the foundational building block of the analog signal chain within the broader hierarchy of amplifier ICs, linear ICs, and semiconductors. Rail-to-rail style input flexibility on single-supply parts like the TLC272 lets designers amplify sensor signals that swing near ground without a negative supply, dramatically simplifying battery-powered and industrial designs. Key features include a maximum input offset voltage of 500 uV at 25 C with VDD = 5 V, extremely low offset drift of typically 0.1 uV/month (including the first 30 days), very high input impedance with low bias currents inherent to CMOS inputs, and a common-mode input range that extends to the negative rail (In to V-). These characteristics make it a cost-effective alternative to BiFET general-purpose amplifiers. The LinCMOS process provides input bias currents in the picoampere range, enabling direct interfacing with high-impedance sources such as pH probes, photodiodes, and piezoelectric sensors without external buffering. The dual amplifier in one SOIC-8 saves board area and improves channel matching in filter and instrumentation circuits. Typical applications include sensor signal conditioning, active filters, battery-powered portable instrumentation, and low-frequency data-acquisition front ends where single-supply, low-bias-current operation is required. Design consideration: keep source impedances moderate and use adequate supply bypassing; the CMOS input is sensitive to static, so observe ESD handling precautions. This page synthesizes distributor pricing, drop-in alternatives, pinout data, and practical design notes not found in the manufacturer datasheet.
TLE2022IDR - Dual Precision Low-Power Op Amp | Texas Instruments
The Texas Instruments TLE2022IDR is a dual precision, high-speed, low-power operational amplifier built on TI's Excalibur bipolar process, housed in an 8-pin SOIC (D) package and rated for the industrial -40C to +85C temperature range. It delivers 2 circuit channels with low offset voltage, high unity-gain bandwidth, and low power consumption typical of the Excalibur family, making it suitable for general-purpose precision signal conditioning from a single supply. The part is specified as a standard (general-purpose) amplifier in TI's amplifier portfolio. What is an operational amplifier (op amp)? An op amp is a high-gain DC-coupled electronic voltage amplifier with differential inputs and, typically, a single-ended output. It is one of the most ubiquitous building blocks in analog electronics, sitting below instrumentation amplifiers and active filters in the signal-chain hierarchy and above individual transistors in functional abstraction. Precision low-power single-supply op amps such as the TLE2022 family are optimized for systems that must operate from a single positive rail (often 3.3V or 5V) while still delivering DC accuracy and AC bandwidth close to what dual-supply parts achieve. Key features of the TLE2022IDR include two independent op-amp channels in a single SOIC-8 footprint, low power consumption characteristic of the Excalibur process, high-speed response relative to competing low-power op amps, unity-gain stability, and support for single-supply operation. The complementary bipolar process uses isolated vertical PNP transistors that improve input common-mode range and slew rate versus older designs, which is one reason the TLE2022 family remains popular as a successor to the OP21 in legacy designs. Typical applications include active filters, precision integrators, sample-and-hold front ends, transducer signal conditioning, and battery-powered instrumentation. The 8-pin SOIC footprint is industry standard, allowing easy hand prototyping and high-density SMT assembly on the same PCB land pattern used by countless alternative dual op amps. When designing with this device, observe the datasheet maximum supply rating and provide proper input common-mode biasing when used on a single supply; the lower rail of the input common-mode range may not extend all the way to ground. Decouple the supply pin close to the IC with at least 0.1 uF ceramic capacitance. A unity-gain stable part can be operated without compensation but should be kept clear of capacitive loads exceeding the datasheet's drive specification.

TLP7820(A-LF4 - 5 kVrms Isolated Amplifier | Toshiba
The Toshiba TLP7820(A-LF4 is a one-channel optically isolated amplifier with analog output, 5000 Vrms isolation, and a SO8L (LF4) package. It operates from 3 V to 5.5 V, supports differential input sensing, and is designed for high-precision current sensing in electronic motor drives. The isolation barrier transfers a measured voltage signal optically while electrically separating the sensed power circuit from downstream control electronics. An isolation amplifier is an analog signal-conditioning IC that combines input amplification, modulation across a galvanic isolation barrier, and signal reconstruction at the output. Unlike a conventional voltage amplifier, its primary purpose is to measure a differential signal while maintaining high-voltage isolation. This places it in the isolated-sensing branch of the industrial, power-conversion, and motor-control semiconductor hierarchy. Key verified characteristics include a 3 V to 5.5 V supply range, differential sensing, 5000 Vrms isolation, and analog output. Toshiba identifies motor phase current sensing and inverter current or voltage sensing as primary use cases. In a typical motor-drive circuit, motor current flows through an external shunt resistor and the resulting differential voltage is measured by the amplifier. The device architecture provides an analog output while preserving a reinforced-style isolation barrier up to the verified 5000 Vrms rating. Its single-channel SO8L package supports compact isolated signal-conditioning layouts, but the exact pin assignments, input range, bandwidth value, propagation behavior, accuracy limits, and temperature limits must be taken from the manufacturer datasheet. Typical applications include three-phase inverter phase-current measurement, DC motor control, industrial inverter monitoring, power-supply current feedback, and isolated analog voltage sensing. The differential architecture suits shunt-based measurements where common-mode voltage is elevated or varies with the switching environment. PCB design should preserve creepage and clearance around the isolation barrier, keep input and output grounds separate, and place the shunt path and amplifier inputs according to the manufacturer layout guidance. Filtering near the sensor input may be needed if switch-node transients exceed the device limits; component values should not be inferred without the complete datasheet specifications. This page consolidates the verified manufacturer and distributor information, separates confirmed TLP7820 characteristics from unavailable parameters, and provides engineering-oriented application and sourcing context rather than treating packaging-code variants as engineering alternatives.
TLP7820(A-TP4 - 5kVrms Isolated Amplifier | Toshiba
The Toshiba TLP7820(A-TP4 is a photocoupler-based isolation amplifier with analog output, 5000 Vrms reinforced isolation, and an 8-pin SO8L package. It is designed primarily for motor phase-current and inverter voltage sensing. The verified source data identifies one differential isolation-amplifier circuit and an 8-SO package, while detailed electrical characteristics are not provided in the supplied records. An isolation amplifier is an analog signal-conditioning IC that transfers voltage information across a galvanically isolated barrier while electrically separating high-voltage circuitry from the low-voltage control domain. In the application hierarchy, the TLP7820 belongs to isolation amplifiers, optically isolated amplifiers, signal-conditioning ICs, analog ICs, and semiconductor devices. Its isolation barrier helps prevent ground faults and high common-mode potentials from reaching measurement, protection, or control electronics. Toshiba identifies the TLP7820 as an analog-output isolation amplifier rated to 5000 Vrms. The official product description specifically targets current sensing in electronic motor drives, where an external resistor produces a voltage proportional to motor current. The TLP7820 senses that voltage across its isolated input side and presents the result on the non-isolated output side. The provided records also associate the device with power-inverter current sensing. The isolation mechanism is optical within a photocoupler-type package. Optical isolation breaks the direct conductive path between input and output while preserving the intended analog signal relationship. In practical systems, the amplifier is paired with a precision shunt resistor, power-supply bypassing, an analog acquisition stage, and a controller such as a motor-drive MCU. Exact gain, bandwidth, input range, common-mode limits, supply requirements, and accuracy must be confirmed in the manufacturer datasheet before release to production. Typical uses include three-phase motor-drive shunt sensing, inverter leg-current measurement, power-converter feedback, and isolated analog-voltage sensing across a high-voltage barrier. Unlike ordinary operational amplifiers placed directly beside a shunt, the TLP7820 provides a defined isolation function suited to systems where the sensed node can sit at a hazardous or elevated potential. PCB design should preserve the isolation barrier by maintaining the package creepage and clearance required by the working voltage and applicable safety requirements. Place input-side and output-side ground returns independently, route copper so isolation barriers cannot be bridged by solder, test pads, or silkscreen-dependent features, and use stable references and supply decoupling appropriate for the measurement accuracy required. This page consolidates the verified Toshiba product-page data, distributor identification, sourcing links, and engineering cautions that are not presented together in the manufacturer overview. Because the supplied web records do not expose a complete parametric datasheet, unsupported values are intentionally marked for verification rather than inferred from generic isolation-amplifier specifications.
TLP7820(B-LF4 - 5V 5kVrms Isolation Amplifier | Toshiba
The Toshiba TLP7820(B-LF4 is a 5 V optically isolated analog-output amplifier with 5000 Vrms reinforced isolation, one isolation channel, and an 8-pin SO8L (LF4) package. It is designed for motor phase-current and inverter voltage sensing, where an external shunt produces a small differential voltage that must be transferred safely across a high-potential barrier. The verified product information identifies an analog output, differential input operation, 3 V to 5.5 V supply range, and a surface-mount SO8L package. An isolation amplifier is an analog signal-conditioning IC that transfers a low-voltage input across an electrical isolation barrier while electrically separating the input and output grounds. Optically isolated amplifiers use an internal light path or other isolation mechanism to prevent high-voltage ground currents and common-mode transients from reaching the measurement system. This product belongs to the isolation-amplifier family of signal-chain ICs rather than a general-purpose operational amplifier. The TLP7820 is intended for current sensing in electronic motor drives. In a typical implementation, motor current flows through an external resistor and the resulting analog voltage drop is sensed by the isolation amplifier. Its differential input arrangement helps reject common-mode voltage at the shunt, while the 5000 Vrms isolation rating supports high-side sensing in inverter and motor-control systems. The analog output can be connected to a controller or monitoring ADC after the system designer confirms the required transfer gain, bandwidth, accuracy, and supply conditions. The verified Toshiba material also references EN IEC 60747-5-5 option (D4) documentation, which is relevant when evaluating isolation-related product qualification requirements. The part is associated with motor phase-current sensing, inverter current sensing, and inverter voltage sensing. The available LCSC listing reports a 5-piece stock example and a starting price of $11.3258, but pricing and inventory are market-dependent and were not provided as a structured XAIPART price schedule. A practical design must preserve the isolation barrier rather than treating SO8L as an ordinary op-amp package. Keep high-voltage and low-voltage copper regions separated, route the shunt signal as a short differential pair, provide local supply bypassing where the datasheet specifies it, and verify creepage, clearance, capacitor insulation, and system-level withstand requirements. The TLP7820(B-LF4 is best considered for isolated measurement in power-conversion equipment after checking the exact option suffix and datasheet revision. This page consolidates manufacturer product information, distributor findings, and cross-reference evidence into an engineering-oriented overview. It distinguishes verified information from fields that still require the latest Toshiba datasheet or authorized distributor quote, helping designers evaluate the TLP7820 without substituting unverified ratings or assuming that a similar package implies drop-in compatibility.

Verified source information identifies the device as a photocoupler-type isolation amplifier with an analog output, 5,000 Vrms isolation rating, and SO8L (LF4) package construction. An isolation amplifier is an optically isolated signal-conditioning IC that transfers a voltage or current-related measurement across an electrical barrier while electrically separating high-power circuitry from the measurement domain. Its internal isolation barrier helps protect low-voltage control and sensing electronics from high common-mode voltages. The TLP7820 family is associated with motor phase-current, inverter-current, and voltage-sensing applications. The verified Toshiba product listing identifies TLP7820(B-TP4 as an isolation amplifier with an analog output and 5,000 Vrms isolation capability. The family is packaged in SO8L (LF4), while distributor and comparison listings describe an 8-pin SO/SOIC-style package. The device is therefore positioned for isolated current-measurement circuits rather than ordinary non-isolated operational-amplifier applications. Because the supplied sources do not provide the complete electrical characteristic table, input common-mode range, gain error, bandwidth, propagation delay, supply-current limits, or exact pin names, those values must be confirmed in the manufacturer datasheet before layout or qualification. This page does not infer unverified numerical specifications. The available evidence supports the device category, isolation rating, analog-output architecture, package family, and target sensing applications. Typical implementation places the TLP7820 across a current-sense shunt or inverter phase-current sensing path. Its isolation barrier allows measurement information to cross from the power stage toward a controller while maintaining galvanic separation. Designers should verify the complete recommended shunt, input filter, supply, output, and grounding configuration in the Toshiba datasheet and evaluate the external resistor network for the intended current range. Design emphasis belongs on barrier isolation, common-mode voltage limits, input-referenced filtering, output scaling, and PCB creepage. The SO8L package should be placed with adequate isolation clearance and a defined high-voltage barrier; copper, slots, and grounded structures must not unintentionally reduce the rated isolation distance. The manufacturer datasheet is the controlling source for layout dimensions and safety requirements. This page consolidates verified manufacturer and distributor information, distinguishes documented facts from missing parameters, and provides application and sourcing guidance. It is intended to help engineers identify the correct isolation-amplifier family and obtain the authoritative Toshiba datasheet before committing to a PCB design.

Toshiba TLP7820(LF4 is a one-channel optically isolated amplifier with analog output, rated for 5000 Vrms isolation and supplied in an 8-pin SO8L (LF4) package. The verified product data identifies differential sensing and a supply range of 3 V to 5.5 V, while the related distributor listings identify the device for motor phase-current and voltage sensing. Its isolated measurement architecture transfers a differential analog signal across a high-voltage barrier, supporting current feedback and protection functions in inverter and motor-drive systems. The SO8L package and 8-SO outline make it suitable for compact isolated-control boards. An isolation amplifier is a signal-conditioning IC that combines an input stage, an isolation barrier, and an output stage. The input stage measures a differential voltage, the barrier transfers that information while maintaining galvanic separation, and the output stage produces an analog voltage for an analog-to-digital converter or controller. In a motor-drive circuit, this arrangement measures voltage across a shunt resistor without connecting the high-voltage power stage directly to the controller ground. The verified data highlights analog output, differential operation, 5000 Vrms isolation, one circuit, and a 3 V to 5.5 V supply range. These features are directly relevant to current sensing in power converters and inverters. The isolation barrier allows sensing information to cross from a noisy power environment to a control domain while maintaining the required separation between those domains. Toshiba’s product page identifies the TLP7820 as an isolation amplifier and isolated delta-sigma modulator product. The manufacturer data retrieved for the device describes current sensing in electronic motor drives, where motor current flows through an external resistor and the resulting voltage drop is sensed. The D4 qualification information references EN IEC 60747-5-5 option D4 for designated part-number conventions, while the standard LF4 designation is used for the package and ordering variant shown here. Typical applications include three-phase inverter current sensing, motor phase-current measurement, DC-link voltage sensing in inverter systems, power-factor correction current feedback, and isolated gate-driver monitoring. The component is most appropriate when the analog sensor signal must remain galvanically isolated from a controller or ADC input. The primary design consideration is maintaining the manufacturer-specified layout and isolation-clearance requirements. The input network, shunt connection, output filtering, supply decoupling, and isolation barrier must be laid out according to the Toshiba datasheet. The verified data does not provide every pin name, electrical limit, thermal value, or timing parameter, so those details remain marked for data-needed rather than estimated.

Toshiba TLP7920(D4 is an optically isolated, analog-output isolation amplifier with 5000 Vrms galvanic isolation, 230 kHz bandwidth, and an 8-pin DIP package. It is designed to transfer analog measurement signals across high-potential barriers in motor drives, inverters, power converters, and industrial current-sense systems. The input side uses sigma-delta analog-to-digital conversion, while the isolated output reconstructs an analog voltage for downstream measurement and control circuits. An isolation amplifier is a signal-conditioning semiconductor that combines an analog input, digital isolation path, and isolated analog output. Unlike a conventional optocoupler intended primarily for switching or logic signals, the TLP7920 family preserves analog amplitude information while maintaining electrical separation between high-voltage and low-voltage domains. This makes it suitable for current and voltage feedback in systems where ground potentials and switching transients can corrupt measurements. The verified distributor and manufacturer sources identify the TLP7920 family for motor phase-current sensing and inverter current/voltage sensing. The listed part is available in an 8-DIP through-hole configuration, while related Toshiba ordering codes include surface-mount and lead-free variants. The TLP7920(D4 designation is associated with the EN IEC 60747-5-5 Option D4 qualification naming convention, as stated in the Toshiba document search result. The isolation amplifier is intended for current sensing through an external shunt resistor. In a motor-drive circuit, the shunt produces a small differential voltage proportional to phase current, and the TLP7920 transmits that measurement across the isolation barrier. The 230 kHz bandwidth figure supports signal bandwidth requirements in power-conversion systems, while the 5000 Vrms specification identifies the isolation rating used when selecting the component for a high-side or barrier-separated measurement channel. Designers should verify the exact Toshiba ordering code, package variant, input range, output range, supply requirements, and timing characteristics against the relevant datasheet before production release. The supplied search data does not provide a complete authoritative parameter table, so values not explicitly present in the provided material are marked as needed rather than inferred. For PCB design, place the isolation device so the high-voltage and low-voltage copper areas maintain their required creepage and clearance, and route input and output return paths separately.
TLP7920(D4-A - 5000 Vrms Isolation Amplifier | Toshiba
The Toshiba TLP7920(D4-A is a precision isolation amplifier with an analog output, 5000 Vrms isolation rating, gain rank A, and an 8-pin DIP package. It is designed for motor phase-current and inverter voltage sensing, where a high-voltage sensing domain must transfer a measured analog signal to a controller across an isolated barrier. An isolation amplifier is an optically isolated signal-conditioning device that combines input amplification, electrical isolation, and output conditioning. In the signal-chain hierarchy, it sits between a sensor or shunt resistor and an analog-to-digital converter or motor-control controller. Its purpose is to preserve measurement information while providing galvanic separation between the input-side power domain and the output-side control domain. The TLP7920 family uses an input-side sigma-delta analog-to-digital conversion technique according to the Toshiba datasheet. The measured input is converted into a digital representation for optical transfer across the isolation barrier, then reconstructed as an analog output on the secondary side. This architecture is intended for current sensing in electronic motor drives, where the sensed voltage across an external shunt is small and isolation from high switching nodes is required. Key application parameters include the 5000 Vrms isolation rating, analog output, gain rank A, 8-DIP package, and a documented operating-temperature range of -40 C to +105 C. The family is associated with a minimum common-mode transient immunity of 15 kV/us. These features make it relevant to motor-control systems, inverter current sensing, phase-current monitoring, and isolated voltage-sensing circuits. When designing around the TLP7920, the shunt or sensing resistor must remain within the input range and power rating of the device, while the controller-side supply and analog input limits must also be respected. The DIP-8 package simplifies through-hole assembly and provides a conventional isolation-amplifier footprint. Because the verified data does not provide complete electrical limits, pin names, pricing tiers, or guaranteed alternative cross-references, those fields remain explicitly marked as data needed rather than inferred. This page combines Toshiba manufacturer information, distributor product records, and the supplied cross-reference results into a technically cautious product reference. It emphasizes application fit, isolation considerations, and the distinction between verified device information and parameters that still require confirmation from the complete manufacturer datasheet.
TLP7920(D4-B - 5 kVrms Isolation Amplifier | Toshiba

It is designed for current sensing in electronic motor drives and inverter systems. The verified product information identifies a one-circuit isolation-amplifier configuration and a 0.300-inch, 7.62 mm 8-DIP package. The device uses optical isolation between the input and output sides, helping transfer a measured analog signal across a high-voltage barrier without requiring a direct galvanic connection. An isolation amplifier is a signal-conditioning IC that combines an input-side sensor interface, optical or other barrier-isolated signal path, and an isolated analog output. Within the broader hierarchy, the TLP7920 belongs to the isolation-amplifier and optocoupler families of analog and interface semiconductors. Its primary role is to preserve signal integrity while providing current sensing for motor phase conductors, inverter systems, and other power-conversion equipment. The verified manufacturer listing specifies analog output, 5000 Vrms isolation, and D4 qualification wording associated with EN IEC 60747-5-5. The Mouser result also identifies gain rank B, VDE approval, and an 8-DIP package. These attributes make the part suitable where a protected measurement path is required between a high-current power circuit and a controller or monitoring system. The exact input range, gain error, bandwidth, supply requirements, output levels, and temperature limits are not included in the supplied verified data and must be confirmed in the manufacturer datasheet before design release. Typical applications include motor phase-current sensing, inverter current sensing, voltage sensing through an external resistor, power-supply feedback, and isolated analog monitoring. In a motor-drive implementation, a shunt resistor produces a voltage proportional to current, and the TLP7920 transfers that measurement through the isolation barrier to a control system. The analog output allows the receiving controller to process the current information without a direct high-voltage connection. PCB design should preserve the isolation barrier and provide adequate copper clearance and creepage around the package. The through-hole 8-DIP format supports conventional through-hole assembly, while the input and output return paths must remain separated according to the datasheet layout guidance. Do not assume that identical pin numbering or package geometry alone guarantees regulatory compliance; the final system must be checked against its applicable safety standard. This page consolidates manufacturer identification, distributor availability, qualification references, application context, and verified cross-reference information. Numerical parameters absent from the supplied sources are intentionally marked for datasheet confirmation rather than inferred.

The TLP7920(D4-LF1,F ordering code includes the manufacturer’s D4 qualification option; the manufacturer document search result references EN IEC 60747-5-5 option D4, but no additional device-specific parameters were supplied here. The isolation amplifier provides a defined interface between a current-sense resistor and the downstream measurement electronics. In a motor-drive implementation, the sensed voltage is applied to the isolated input side, and the analog output is generated on the output side. This arrangement helps protect control circuitry from high common-mode voltage and ground-potential differences. The exact input range, gain, bandwidth, accuracy, propagation delay, and common-mode limits must be confirmed from the manufacturer datasheet before final design release. Typical applications include three-phase motor inverter monitoring, motor phase-current measurement, inverter current sensing, power-factor monitoring, industrial motor control, and isolated analog measurement. The device is suitable when the design requires reinforced signal separation and an analog output rather than a digital isolated communication interface. The 8-SMD format also supports surface-mount assembly, although the exact PCB land pattern and pin numbering must be taken from the Toshiba datasheet. Designers should verify the input resistor, output-side supply, decoupling, isolation barrier, creepage and clearance, and analog filtering requirements against the manufacturer datasheet. The isolated barrier is a safety and reliability boundary, so PCB layout must preserve the required spacing and avoid placing high-voltage copper beneath or across the isolation region. This page consolidates verified manufacturer and distributor information, available replacement context, and practical design guidance without inventing unprovided electrical values.
TLP7920(F - 5000 Vrms Isolated Amplifier | Toshiba

The TLP7920(F belongs to the broader isolation-amplifier and optoelectronics hierarchy, combining an internal phototransistor isolation mechanism with analog amplification. Its differential input arrangement is suited to sensing the voltage developed across a current-sense resistor in a motor-drive power stage. The verified manufacturer material specifically positions the TLP7920 and TLP7920F for current sensing in electronic motor drives. The datasheet search result states that motor current flows through an external resistor and the resulting analog voltage drop is sensed by the device. This makes the part applicable to inverter control, motor phase monitoring, power-factor correction equipment, and isolated industrial measurement interfaces. The TLP7920F variant is associated with an 8-DIP package and analog output. Its isolation rating of 5000 Vrms supports designs that require reinforced separation between a high-side or power-stage sensing node and downstream control circuitry. The device is not a general-purpose precision op-amp; its application depends on the external current-sense resistor, input network, supply arrangement, isolation barrier, and analog output connection described in the Toshiba datasheet. For motor-control use, place the isolation amplifier at the power-conversion interface and connect its inputs across the selected sense resistor. Keep the high-voltage and isolated signal paths physically separated from control-side traces, maintain the datasheet-defined creepage and clearance requirements, and route analog output wiring away from switching nodes. This page combines verified manufacturer and distributor information, available cross-reference results, and practical engineering guidance without inventing missing electrical parameters.
TLV07IDR - 36V Precision Rail-to-Rail Op Amp | Texas Instruments
The Texas Instruments TLV07IDR is a single precision operational amplifier with a 36 V supply range, rail-to-rail output operation, low noise, and a 1 MHz gain-bandwidth product. It is packaged in an 8-pin SOIC and accepts single-supply operation from 4.5 V to 36 V or dual-supply operation from ±2.25 V to ±18 V. Its typical input offset voltage is 20 µV, with a maximum of 150 µV and typical input offset drift of 1 µV/°C. A precision operational amplifier is a voltage-feedback analog IC that amplifies the difference between two input voltages while using negative feedback to set the closed-loop gain. The TLV07 belongs to the operational amplifier hierarchy, which sits within analog signal-chain ICs and broader semiconductor devices. It is intended for instrumentation, buffering, signal conditioning, and precision control paths that require low offset and low noise. The TLV07 combines a wide 36 V operating range with rail-to-rail output capability, allowing the output to approach the supply rails under suitable load conditions. Its 1 MHz gain-bandwidth product supports moderate-bandwidth closed-loop amplifier designs, while the 0.7 V/µs slew rate is useful for signals requiring controlled transitions. The low-noise architecture is particularly relevant when small sensor, measurement, or control signals must be amplified without adding excessive broadband noise. The input common-mode range and output-swing behavior must be checked against the actual supply and load conditions. In designs using high supply voltages, input-current limiting is important: the manufacturer data recommends limiting input current to 10 mA. The 8-SOIC package facilitates conventional surface-mount assembly, while the exposed thermal considerations depend on the board footprint and operating dissipation rather than the package alone. Typical uses include industrial instrumentation, low-level sensor amplification, analog measurement chains, precision buffer stages, process-control interfaces, and low-noise signal conditioning. The TLV07IDR is preferable where a single op amp and a 36 V-capable supply simplify the design, but application engineers should confirm input range, output swing, noise, stability, and load-drive requirements against the datasheet and their specific operating conditions. For PCB implementation, place decoupling capacitors close to the supply pins and route feedback and signal paths away from switching nodes. Stable feedback-network component values and careful grounding help preserve precision performance. This page combines manufacturer information, distributor availability, package details, pricing context, and design guidance for faster engineering evaluation.

Pricing starts around $0.45 as of 2026-08-30.
TLV2452AIDGKR - Dual 23uA RRIO Op Amp 220kHz | Texas Instruments
The Texas Instruments TLV2452AIDGKR is a dual, micropower rail-to-rail input/output (RRIO) operational amplifier in an 8-pin VSSOP (MSOP, DGK) package. It operates from 2.7V to 6V single supply (or ±1.35V to ±3V dual supplies) while consuming only 23uA per channel, with a 220kHz gain-bandwidth product and 0.11V/us slew rate. An operational amplifier is a high-gain differential-to-single-ended voltage amplifier and a fundamental building block of analog signal chains, used as buffers, active filters, comparators, and transimpedance amplifiers. Op amps sit within the linear IC hierarchy alongside comparators and voltage regulators; the TLV2452 belongs to the low-power (micropower) op amp family, which prioritizes ultra-low quiescent current for battery-operated systems. Key features include true rail-to-rail input common-mode range and rail-to-rail output swing to within 5mV of each rail at light loads, maximizing dynamic range in low-voltage designs. The A-grade version guarantees a maximum input offset voltage of 1.5mV, and CMOS inputs deliver 1pA typical input bias current for high-impedance sensor interfaces. Micropower 23uA-per-channel consumption directly extends battery life in always-on circuits. Fabricated on a CMOS process, the TLV2452 offers high input impedance with internal ESD protection and is specified from -40C to +125C. The dual-channel DGK-8 package saves board space versus two single amplifiers. According to the TLV245x datasheet (Rev. F), the family also includes shutdown variants for further power savings. Typical applications include battery monitoring, portable medical devices, photodiode amplification, and low-power active filters. Rail-to-rail output allows direct ADC interfacing without level shifting, and the low quiescent current suits IoT always-on sensing. Design tip: decouple the supply with a 0.1uF ceramic close to V+, and remember the 220kHz GBW limits closed-loop bandwidth - keep gains and filter frequencies modest to preserve phase margin.
TLV2452AIDGKR-Q1 - Dual 220kHz RRIO Op Amp, 23uA | TI
The Texas Instruments TLV2452AIDGKR-Q1 is an automotive-grade (AEC-Q100 qualified) dual micropower rail-to-rail input/output operational amplifier consuming only 23 uA per channel while delivering 220 kHz of gain-bandwidth product, supplied in an 8-pin VSSOP (DGK) package. It operates from a single 2.7 V to 6 V supply and is qualified for AEC-Q100 Grade 1 temperature (-40C to +125C). A rail-to-rail input/output operational amplifier is a type of precision op amp within the broader analog amplifier family whose input common-mode range and output voltage swing extend to within millivolts of both supply rails. This maximizes dynamic range in low-voltage, single-supply systems where signal levels approach the rails, a capability conventional op amps cannot provide. Key features include the industry-leading 23 uA/channel quiescent current (far below competitive devices at similar bandwidth), 220 kHz gain-bandwidth product, rail-to-rail input and output (RRIO) operation, and high output drive capability for its power class. The dual-channel integration saves board space and reduces BOM count in multi-channel signal chains. The TLV245x family achieves its performance point through a trimmed CMOS input stage combined with rail-to-rail output buffer architecture, providing stable gain-bandwidth across the full load range. The related TLV245x family also offers shutdown variants (TLV2453/2455) for further average-power reduction in duty-cycled systems. Typical automotive and industrial applications include battery monitoring and current sensing front ends, low-power sensor signal conditioning, portable instrumentation, and microcontroller ADC driver stages, where micropower consumption directly extends battery life and reduces self-heating. Design consideration: because gain-bandwidth is 220 kHz, keep closed-loop gains moderate for signal bandwidths above a few tens of kHz; with 23 uA supply current, output current drive is limited, so avoid heavy capacitive loads without isolation resistors.
