THS6093CD - 275mA +12V ADSL Line Driver | Texas Instruments
N.º da peça: THS6093CD ✓ AtivoTHS6093CD Visão geral
An ADSL line driver is an interface integrated circuit that converts upstream data signals into suitable current and voltage levels for transmission over copper lines. It belongs to the interface IC hierarchy within integrated circuits and semiconductor signal-conditioning devices. The THS6093 is intended for full-rate ADSL and G.Lite equipment, including customer-premises equipment and power-line communication equipment where the line interface must combine high output current with controlled noise.
Key features include compatibility with a 1:2 transformer ratio, a wide supply-voltage range, and suitability for single +12 V operation. The 275 mA output capability provides useful drive current for line termination and transformer coupling. The device also includes shutdown control, allowing a system to disable the driver when line transmission is not required. Low noninverting current noise of 2.1 pA/√Hz helps reduce noise coupled through a telephone hybrid into the downstream receiver path.
The THS6093 uses a high-current output stage suited to the demanding load presented by an ADSL line interface. Its architecture supports both transformer-coupled and single-supply arrangements, giving designers flexibility in line-network topology. The 14-pin SOIC package is a conventional surface-mount format suitable for automated PCB assembly, although the high-current output path requires careful routing, thermal review, and adequate copper around the power and ground pins.
Typical uses include ADSL CPE line interfaces, full-rate ADSL modems, G.Lite access equipment, PLC gateways, and communications terminals connected to copper lines. It is particularly relevant when the design needs a dedicated line driver with a shutdown control and operation from a +12 V supply rather than a general-purpose low-power amplifier.
For PCB implementation, place the device close to the line-transformancer or network interface and keep the high-current output path compact. Use a low-inductance supply connection and adequate input and output bypassing according to the manufacturer application guidance. Verify maximum output current, voltage, and thermal conditions across temperature because 275 mA describes the line-driver capability rather than unlimited continuous load capacity.
This product record combines the manufacturer identification, package information, current capability, major ADSL and PLC use cases, and practical implementation considerations. It also provides sourcing guidance for the exact THS6093CD ordering code and distinguishes confirmed specifications from parameters that still require confirmation from the manufacturer datasheet.

Aplicações típicas
THS6093CD é adequado para 6 aplicaçãos: ADSL CPE Line Interface, Full-Rate ADSL Modem, G.Lite Access Terminal, Power-Line Communication Gateway, Telephone-Line Interface Circuit, Communications Terminal Equipment.
ADSL CPE Line Interface
The THS6093CD fits an ADSL customer-premises equipment line interface because it combines a 275 mA line-driver output with operation from a +12 V supply. It can sit on the transmit side of a transformer-coupled copper-line network and drive the required current into the termination and external network. The 1:2 transformer-ratio compatibility directly supports common ADSL line-interface topologies. During design-in, verify the transformer ratio, line impedance, peak current, and output voltage against the manufacturer application circuit, because interface compliance depends on the complete external network rather than on the IC alone.
Full-Rate ADSL Modem
A full-rate ADSL modem can use the THS6093CD as the dedicated copper-line transmitter because the device supports full-rate ADSL service, a 275 mA output current, and +12 V single-supply operation. Its noninverting current noise of 2.1 pA/√Hz helps limit unwanted noise that could otherwise reach downstream circuitry through the telephone hybrid. The line driver should be placed close to the transformer and line network, with a low-inductance supply path and manufacturer-recommended bypassing to preserve signal quality and reduce unwanted emissions.
G.Lite Access Terminal
The THS6093CD is appropriate for G.Lite access equipment where a compact line interface must support both full-rate and reduced-rate ADSL service families. Its dedicated line-driver stage offers 275 mA capability, while the shutdown function lets the terminal disable transmit circuitry during idle or control states. The +12 V supply arrangement simplifies integration into communications equipment that already uses a positive rail. Engineers should still evaluate transformer coupling, downstream noise isolation, and the required output waveform over line impedance and temperature conditions.
Power-Line Communication Gateway
The THS6093CD can serve as the line-driver element in a PLC gateway designed around a copper-network interface compatible with its ADSL-oriented drive characteristics. The 275 mA output current provides sufficient drive capability for the external line network, and the 1:2 transformer-ratio compatibility supports a familiar isolation or coupling arrangement. Its low 2.1 pA/√Hz noninverting current noise is useful in mixed-signal equipment where line-driver noise can otherwise couple into other channels. Final EMI and conducted-emissions performance requires system-level testing with the actual coupling network.
Telephone-Line Interface Circuit
A telephone-line interface can use the THS6093CD when the design requires a high-current transmit path with controlled shutdown behavior. Its 275 mA drive capability suits transformer-coupled line networks, and the dedicated line-driver architecture is more application-focused than a general-purpose op amp. The low noninverting current noise can reduce feedback through a hybrid toward the downstream path, which is important in full-duplex equipment. Layout should isolate the line-driver output from sensitive receive circuitry and keep the high-current return path compact to minimize inductive coupling.
Communications Terminal Equipment
The THS6093CD is suitable for communications terminals requiring an ADSL or PLC transmitter in a 14-pin surface-mount package. The +12 V operating point supports integration with positive-rail terminal power, while shutdown control provides a direct method for managing the line-driver state. Its 275 mA output rating and transformer compatibility align with high-current copper-line interfaces rather than low-power signal processing. When laying out the board, follow the manufacturer application guidance for decoupling and output routing, and verify thermal performance if the line driver operates continuously at its maximum current.

Notas de projeto
Place the THS6093CD close to the line transformer and termination network to minimize the length of the high-current output path. Keep the supply and ground connections short and use low-inductance routing for the +12 V rail. The 275 mA output capability makes conductor and via resistance relevant, so the PCB must provide adequate copper width and parallel current paths where necessary.
Use the manufacturer-recommended input, output, and bypass capacitors at the device pins. Place high-frequency bypass capacitance close to the supply pins rather than at the connector or transformer. Confirm that the supply source can support the dynamic line-driver demand without excessive droop. Because the THS6093CD operates from a nominal +12 V supply, check the full allowable range and output-current limit in the Texas Instruments data sheet before selecting the regulator and protection network.
Evaluate the line-driver output, transformer, termination, and hybrid as one signal path. The 2.1 pA/√Hz noninverting current-noise characteristic can reduce unwanted feedback into the downstream path, but layout coupling may still dominate system noise. Maintain separation between the 275 mA output route and sensitive receive nodes, and use a ground reference strategy that avoids forcing return current through the line-output region.
Do not treat the 275 mA rating as permission to load the output continuously without checking thermal and electrical limits. Confirm the exact shutdown polarity, output-state behavior, and maximum output voltage from the manufacturer pin table. Also validate the 1:2 transformer orientation and termination values against the approved application circuit; a mechanically similar line driver with different output limits may not be interchangeable.
