THS6052CD - 175mA ±12V ADSL CPE Line Driver | TI
Référence : THS6052CD ✓ ActifTHS6052CD Présentation
An ADSL line driver is a specialized interface amplifier that converts a low-level transmit signal into the voltage and current levels required by a copper telephone line. The THS6052CD belongs to the interface-IC and line-driver hierarchy, combining signal conditioning with the drive capability needed to overcome line attenuation and transformer losses. Its ±12 V operating capability also makes it suitable for bipolar line interfaces where a single positive supply would not provide adequate output swing.
The main feature of the THS6052CD is its combination of high output current, low current noise, and a wide supply range. The 175 mA output-current capability provides margin for driving the line through transformer windings and termination networks. The 2.7 pA/√Hz noninverting current-noise specification helps preserve signal integrity when the driver is used in sensitive transmit paths. A wide operating supply range supports both conventional ADSL equipment and power-line-related line-driver circuits.
The THS6052CD uses an 8-SOIC package, which is a surface-mount package in the SOIC family. The device is specified for 0 to 70 °C operation in the distributor data supplied for the THS6052CD. Its architecture is intended for high-current line driving rather than general-purpose low-power signal conditioning, so the external transformer, termination, protection, and biasing network must be designed around the specified output-current and supply-voltage limits.
Typical applications include ADSL customer-premises equipment, G.Lite modems, DSL line-interface networks, telephone-line splitters, and PLC-style line-driver interfaces. In these systems, the THS6052CD is placed between the upstream transmit signal path and the line transformer, with local feedback used to establish the required drive level and bandwidth. The device can reduce the number of external drive components when its current capability and noise performance match the transformer and network requirements.
Designers should pay particular attention to supply bypassing, transformer selection, output-current margin, and protection against transient events on the telephone line. The SOIC package also requires careful thermal assessment when operating continuously near the 175 mA output-current capability. The available verified information does not provide a complete pinout table, detailed timing characteristics, or a complete set of quantitative electrical limits, so those values are identified in the specification fields as data needed for final design sign-off.
This page combines the verified Texas Instruments product identity, distributor package and pricing information, relevant source links, and engineering-oriented selection guidance. It is intended to help engineers identify whether the THS6052CD matches the required ADSL line-driver application before downloading the official manufacturer datasheet and completing detailed circuit validation.

Applications typiques
THS6052CD convient pour 6 applications: ADSL Customer-Premises Equipment, G.Lite ADSL Modem Transmit Path, Telephone-Line Splitter Interface, PLC-Style Line-Driver Interface, Modem and Network Equipment, High-Output Interface Amplification.
ADSL Customer-Premises Equipment
The THS6052CD fits the transmit side of an ADSL CPE because it combines a 175 mA output-current capability with ±12 V operation and low 2.7 pA/√Hz noninverting current noise. The driver is placed before the external line transformer and supplies the current required to launch the downstream signal onto copper. Its two-driver configuration can serve complementary signal paths in the modem transmit circuit. The principal design benefit is the availability of substantial line-drive current without adding a discrete output-current stage, although the transformer ratio, load, and output swing must be verified against the manufacturer datasheet before layout is released.
Recommandé
G.Lite ADSL Modem Transmit Path
The THS6052CD is suitable for G.Lite modem transmit circuitry because the verified feature set identifies support for both full-rate ADSL and G.Lite. Its 175 mA drive capability gives the design margin needed to drive the line through a 1:1 transformer arrangement, while the 2.7 pA/√Hz current-noise specification helps preserve the integrity of the transmitted signal. The IC is normally used with feedback, filtering, line termination, and transformer coupling defined by the target network. Designers should compare the exact G.Lite spectral mask and peak line current against the detailed Texas Instruments electrical limits.
Recommandé
Telephone-Line Splitter Interface
A splitter interface can use the THS6052CD when the downstream copper path requires the specified 175 mA current capability and bipolar drive swing. The device is intended to work with a 1:1 transformer ratio, making it a practical choice when the external network and transformer are already designed around that topology. Low current noise can reduce unwanted contribution to the downstream channel, while the wide supply-voltage range supports ±12 V line-interface architectures. Final selection requires checking output waveform, clipping behavior, thermal dissipation, and isolation requirements in the official datasheet.
Recommandé
PLC-Style Line-Driver Interface
The THS6052CD can serve as a high-current line-drive element in PLC-oriented interfaces because Texas Instruments identifies it as a 175 mA, ±12 V ADSL CPE and PLC line driver. The device provides enough current capability for transformer-coupled copper interfaces while maintaining a low specified noninverting current-noise density. In implementation, the output network must limit fault current and comply with applicable telephone-line transient protection requirements. The verified data does not include complete PLC bandwidth, distortion, or protection ratings, so engineers should use the manufacturer datasheet for those qualifications.
Recommandé
Modem and Network Equipment
The THS6052CD is appropriate for legacy modem and network-interface equipment where a dedicated copper-line driver is required instead of a general-purpose amplifier. Its 175 mA output current, dual-driver arrangement, and SOIC-8 package make it practical for compact equipment designs with an external line transformer. The low 2.7 pA/√Hz noninverting current-noise figure is especially relevant when the driver contributes directly to the transmitted signal. System designers should still validate channel bandwidth, peak output voltage, load impedance, and thermal rise under continuous operating conditions.
Recommandé
High-Output Interface Amplification
Where a telephone-line or communications interface requires more current than a conventional small-signal amplifier can provide, the THS6052CD offers a 175 mA line-drive solution in an 8-SOIC package. The low current-noise rating helps preserve the small-signal integrity of the drive stage, while dual outputs provide two channels for complementary or parallel routing. The circuit should include local feedback and impedance control to define gain and bandwidth. Because the verified material does not specify slew rate, gain-bandwidth product, output impedance, or complete thermal resistance, those parameters must be obtained from the official manufacturer documentation.

Notes de conception
The verified THS6052CD information identifies ±12 V operation, so the design must provide both supply rails with appropriate bypass capacitance and verify that every rail remains within the manufacturer limits. Because the device supports a 175 mA output current, supply routing should account for the peak load imposed by the external transformer and line network. Place local high-frequency bypass capacitors at the supply pins, keep their return paths short, and use the exact capacitor values and stability guidance from the manufacturer datasheet.
Estimated: at a 24 V total supply span and 175 mA output, the worst-case theoretical output-stage dissipation could approach 4.2 W before accounting for actual quiescent current, duty cycle, clipping, and load waveform. Actual dissipation will usually be lower because the output does not continuously cover the full rail-to-rail swing. Use the datasheet thermal model and measured operating waveform to size copper area and assess the SOIC-8 junction temperature; do not treat this estimate as a guaranteed worst-case rating.
Keep the line-driver output path compact and isolate it from sensitive receive or feedback paths. The THS6052CD is designed for compatibility with a 1:1 transformer ratio, so the transformer connection, output impedance, and feedback components should follow the reference topology. Avoid routing high-current output traces beneath sensitive analog or digital nodes, provide a continuous ground reference, and place the local supply bypass components adjacent to the IC to minimize loop area and switching-transient coupling.
Do not treat a matching 8-SOIC outline as proof of an equivalent device. THS6052ID and THS6052CDR have explicit complete-replacement evidence in the verified cross-reference results, whereas THS6042IDR and THS6062CD require pin-level and electrical validation. Confirm output-current limits, supply range, gain, bandwidth, slew rate, thermal performance, and package suffix before substituting any candidate. The THS6052CD package drawing and exposed-pad requirements should also be checked in the official datasheet.
