THS6043ID - 350mA ±12V ADSL CPE Line Driver | TI
MPN: THS6043ID ✓ فعالTHS6043ID نمای کلی
An operational amplifier is an amplifier IC whose high open-loop gain and feedback configuration amplify voltage differences between its inputs. The THS6043 belongs to the operational-amplifier hierarchy and is specialized as a high-speed line driver within the broader amplifier IC category. In ADSL and power-line communication equipment, a line driver strengthens signals before they pass through a transformer coupling network and onto a copper line.
The most prominent characteristics are its 350 mA output-drive capability, ±12 V dual-supply operation, integrated shutdown function, and suitability for full-rate ADSL and G.Lite service. A stated distortion figure of 79 dBc is reported when driving a 100 Ω load at 2 V peak-to-peak. Its low noninverting current noise of 2.1 pA/√Hz is intended to reduce noise feedback through the hybrid into the downstream communication channel.
The THS6043 uses a high-speed operational-amplifier core with current-capable outputs suited to transformer-coupled line interfaces. Its dual-channel arrangement allows one package to serve the transmit path of an ADSL or PLC CPE design. Because the driver dissipates power as voltage and current are applied to the line load, adequate supply-decoupling layout and thermal planning remain important even though the quoted 8.2 mA supply current per channel is much lower than the 350 mA output-current capability.
Typical applications include ADSL customer-premises equipment, G.Lite-compatible access terminals, PLC line interfaces, remote-terminal transmit drivers, and central-office line-driving stages. The 14-pin SOIC package is suitable for conventional surface-mount assembly and copper-based thermal spreading, subject to the manufacturer's layout and maximum electrical ratings.
Designers should verify the exact pin configuration, recommended external network, transformer ratio, allowable output swing, and shutdown logic in the manufacturer datasheet before layout release. Particular care is required when driving low-impedance lines because excessive output current, voltage overshoot, or incorrect transformer coupling can violate device ratings even when nominal ADSL operation is maintained.
This page consolidates verified manufacturer and distributor information, distinguishes available evidence from unverified parameters, and provides application guidance, comparison limitations, and drop-in-replacement criteria that are not presented as a substitute for the original THS6043 datasheet.

کاربردهای معمول
THS6043ID مناسب است برای 6 کاربردs: ADSL Customer-Premises Equipment, G.Lite Access Terminal Interface, Power-Line Communication Line Driver, Remote-Terminal Transmit Driver, Central-Office Line Interface, Transformer-Coupled Communications Output.
ADSL Customer-Premises Equipment
The THS6043ID fits an ADSL CPE transmit path because it is specified as a 350 mA, high-speed line driver for full-rate ADSL and G.Lite service. Its dual-channel 14-pin SOIC implementation can support line-driving functions while its ±12 V operating point provides the headroom expected in this equipment class. The manufacturer-reported 79 dBc distortion at a 100 Ω load and 2 Vpp gives engineers a concrete baseline, while 2.1 pA/√Hz noninverting current-noise density can help limit noise coupling. The external transformer and output network must still match the required 1:1 ratio and be designed from the manufacturer guidance.
G.Lite Access Terminal Interface
The THS6043ID is suitable for a G.Lite-compatible access terminal because the manufacturer identifies it as compatible with both full-rate ADSL and G.Lite. Its 350 mA output capability is valuable when the line-driver stage must energize a transformer-coupled interface rather than operate only at microphone or sensor signal levels. Two channels are provided in one 14-pin SOIC, simplifying board allocation compared with two separate packages. Before schematic release, engineers should verify pin-level enable behavior, bypass placement, allowable output swing, and the exact transformer coupling network required by their line-card design.
Power-Line Communication Line Driver
The THS6043ID can serve as the line-driver element in PLC equipment because the Texas Instruments product family is identified as a 350 mA ADSL CPE and PLC line driver with shutdown. A current-capable output is appropriate for driving a communications transformer and presenting the required signal amplitude into the line interface. The 8.2 mA per-channel supply-current figure and the shutdown feature help engineers balance communication performance with system power management. Since the verified information does not specify the full PLC modulation bandwidth or recommended external network, those details should be confirmed in the manufacturer datasheet before using the device in a new PLC design.
Remote-Terminal Transmit Driver
The THS6043ID matches a remote-terminal transmit stage that must increase the voltage and current available to a copper-line interface. Its high-speed dual operational-amplifier architecture supports communications signal handling, while the rated 350 mA output capability provides margin relative to ordinary low-power amplifier ICs. The manufacturer-reported 79 dBc distortion under a 100 Ω, 2 Vpp test condition offers a reference for expected line-driver behavior. Layout should keep the high-current output loop compact, provide local supply bypassing, and follow the datasheet-recommended transformer and termination arrangement to preserve signal quality.
Central-Office Line Interface
The THS6043ID can be evaluated for central-office line-driver circuitry where a ±12 V communications interface requires more output current than a conventional precision op-amp. The two channels allow a transmit function to be implemented in a compact 14-pin SOIC footprint, and the shutdown control can support power-conservation strategies when a line is inactive. The device’s 350 mA drive rating is the primary selection criterion, followed by verification of signal bandwidth, output-voltage swing, thermal behavior, and protection-network requirements. Exact absolute maximum ratings and recommended layout details are not present in the verified snippets and must be obtained from the manufacturer documentation.
Transformer-Coupled Communications Output
The THS6043ID is appropriate for a transformer-coupled communications output that requires a 1:1 transformer ratio and a high-current driver. Its dedicated line-driver configuration is more suitable than a general-purpose operational amplifier when the output must drive a 100 Ω-class line under the cited 2 Vpp, 79 dBc distortion condition. The device can be placed between the upstream communications signal source and the line transformer, with local decoupling and controlled return paths reducing radiated or conducted noise. Engineers should confirm the transformer impedance, peak current, flyback behavior, and maximum output compliance before finalizing the interface.

یادداشت‌های طراحی
Validate both quiescent supply current and output dissipation rather than sizing the supply from the 8.2 mA per-channel figure alone. A 350 mA line-driver output can create substantial instantaneous demand during signal transitions. Use the manufacturer datasheet for output-current and supply-voltage limits, place low-ESR bypass capacitors close to the supply pins, and keep high-current return paths compact so supply noise is not injected into the communications channel.
Route the line-driver output and transformer connection with minimal loop area because this is a high-current, high-speed communications path. Keep the output loop away from sensitive analog inputs, route the shutdown signal away from the output network, and use a continuous ground reference beneath the device where the recommended layout permits. The supplied data does not include the official PCB artwork, so follow the manufacturer reference layout rather than relying on generic SOIC guidance.
Do not treat the THS6043 as a conventional low-power precision op-amp. Its 350 mA drive rating, transformer coupling requirement, and ±12 V operating environment make incorrect output loading or supply sequencing especially important. Confirm the shutdown polarity, signal-pin assignments, transformer ratio, maximum output swing, and protection requirements directly from the manufacturer datasheet. A conventional SOIC pin-number sequence must not be assumed for a dual high-speed line-driver package.
Perform a thermal check at the highest expected line frequency, output voltage, and load current because dissipated power depends on the actual output waveform rather than only supply-current consumption. Estimate package and copper-plane temperature rise using the manufacturer’s thermal parameters, then preserve adequate spacing from heat-sensitive components. If the line-driver dissipation or adjacent converter heat raises the board temperature beyond the assumed ambient, reduce loss through impedance matching or improve copper spreading.
