Product details
Overview
TS613IDW from STMicroelectronics is a dual wideband operational amplifier engineered for high-output-current line driving in ADSL upstream transmission paths. It delivers 160mA into 25Ω at ±6V supply, features 3nV/√Hz input voltage noise, 40V/µs slew rate, and −77dBc third-order intermodulation distortion at 70/80kHz tones - enabling simultaneous multi-carrier amplification with ultra-low spectral contamination.
For engineers reviewing the TS613IDW datasheet, TS613IDW pinout, TS613IDW application, or TS613IDW equivalent, this device is selected for high-fidelity analog signal integrity in symmetric ±6V or single +12V differential line driver designs where harmonic and intermodulation distortion must be minimized below −70dBc across 100kHz bandwidth.
Technical Context
The TS613IDW integrates two independent high-speed op-amps sharing thermal management via an exposed thermal pad electrically isolated but thermally coupled to the die. Each channel supports closed-loop gains of +2 to +11 with ≥60° phase margin into 25Ω//15pF loads, and maintains stable operation under ±2.5V to ±6V supply conditions.
Its architecture prioritizes low-noise, high-slew-rate performance with rail-to-rail output swing capability (±4.5V at 160mA), common-mode input range extending to (VCC+)−1V, and robust 200mA short-circuit current limiting per output - all optimized for broadband analog signal conditioning in DSL physical layer interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 130MHz typical - enables stable unity-gain compensation up to 130MHz or closed-loop gain of +11 at 20MHz with 100Ω load. |
| Slew Rate | 40V/µs typical - supports clean 100kHz sine wave output at 4Vpp without slewing-induced distortion. |
| Output Current (DC) | 160mA min. into 25Ω - sufficient to drive ADSL upstream line impedance with 12.4Vpp differential signal after 1:2 transformer ratio. |
| Input Voltage Noise | 3nV/√Hz at 100kHz - preserves SNR in multi-tone upstream signals where carrier-to-noise ratio directly impacts bit error rate. |
| THD @ 100kHz | −69dB typical - ensures <0.08% total harmonic distortion for 4Vpp output, critical for maintaining spectral purity in FDM-based DSL systems. |
| IM3 @ 70/80kHz | −77dBc typical - guarantees third-order intermodulation products remain >77dB below fundamental tones, meeting ADSL upstream mask requirements. |
| Supply Voltage Range | ±2.5V to ±6V - compatible with both dual-supply lab evaluation and single +12V biasing via mid-rail virtual ground. |
Pinout & Package
TS613IDW is housed in an SO8 Exposed-Pad plastic micropackage (package code DW), featuring a thermally enhanced copper pad on the underside electrically isolated from all pins and intended for connection to −VCC ground plane on PCB for optimal thermal dissipation (Rthjc = 16°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Non-Inverting Input (Ch1) | High-impedance input node for Ch1; common-mode range extends to (VCC+)−1V. |
| 2 | Inverting Input (Ch1) | Differential input pair node; offset voltage ≤6mV max over temperature. |
| 3 | Output (Ch1) | Capable of sourcing/sinking ±200mA; requires external series resistor (12.5Ω) for 25Ω line matching. |
| 4 | VCC− | Negative supply rail; thermal pad may be connected to this potential for improved heat conduction. |
| 5 | VCC+ | Positive supply rail; decoupling capacitor (100nF) required near pin for stability. |
| 6 | Non-Inverting Input (Ch2) | Independent Ch2 input; channel separation >20dB at 1MHz ensures minimal crosstalk in differential driver mode. |
| 7 | Inverting Input (Ch2) | Matches Ch1 input characteristics; bias current ≤15µA max over temperature. |
| 8 | Output (Ch2) | Complementary output for differential signaling; used with Ch1 to generate balanced 18Vpp diff. signal. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low intermodulation distortion | −77dBc IM3 at 70/80kHz - meets stringent ADSL upstream spectral mask for multi-tone transmission. |
| High output current capability | 160mA into 25Ω at ±6V - eliminates need for external current-boosting stages in line driver applications. |
| Thermally optimized package | SO8 Exposed-Pad with Rthja = 60°C/W - enables 2W power dissipation at 25°C ambient, critical for sustained ADSL emission duty cycle. |
| Low input voltage noise | 3nV/√Hz at 100kHz - preserves dynamic range in wideband analog front-end without degrading SNR. |
| Dual-channel independence | Channel separation >20dB at 1MHz - maintains signal integrity in differential configurations without cross-talk degradation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-output-current, low-distortion operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6629MA/NOPB | Higher GBP (1.5GHz), lower noise (1.4nV/√Hz), but only 100mA output into 50Ω; no exposed-pad package. | Optimized for RF/IF gain blocks, not line driving into 25Ω; lacks thermal performance for sustained ADSL emission. | Select when bandwidth >500MHz is required and load impedance ≥50Ω; avoid for 25Ω line driver duty. |
| THS3091D | Higher slew rate (2000V/µs), 250mA output, but higher THD (−55dB at 100kHz); SO-8 without thermal pad. | Targeted at pulse amplification, not multi-tone linear amplification; IM3 not characterized for DSL frequencies. | Choose for transient-heavy applications like laser drivers; unsuitable for ADSL upstream spectral purity requirements. |
Compared with LMH6629MA/NOPB and THS3091D, TS613IDW uniquely balances 160mA/25Ω drive strength, −77dBc IM3, and 60°C/W thermal resistance in a cost-effective SO8 Exposed-Pad - making it the only option validated for continuous-duty ADSL upstream line driving under ±6V supply.

FAQ
Is TS613IDW still in active production?
No - TS613IDW is marked as Obsolete by STMicroelectronics per its December 2002 datasheet. However, Aetrix Electronics maintains legacy inventory with full traceability and offers engineering support for continued use in existing ADSL infrastructure designs and repair programs.
Can TS613IDW operate from a single +12V supply?
Yes - the TS613IDW supports single-supply operation with proper mid-rail biasing (e.g., 47kΩ resistive divider to generate +6V reference). Its input common-mode range extends to (VCC+)−1V and output swings within 0.5V of rails, enabling full 0–12V dynamic range in differential driver configurations.
What is the purpose of the exposed thermal pad on TS613IDW?
The exposed pad provides a low-thermal-resistance path (Rthjc = 16°C/W) from die to PCB copper, allowing 2W power dissipation at 25°C ambient. It is electrically isolated and should be soldered to a −VCC-connected copper pour to enhance thermal performance without compromising signal integrity.
How does TS613IDW achieve −77dBc IM3 performance?
This performance results from proprietary ST bipolar process optimization, symmetric internal layout minimizing even-order distortion, and high open-loop gain (>11000 V/V) enabling precise closed-loop linearity. Measured with 70/80kHz tones at 12.4Vpp into 25Ω//15pF, it reflects actual hardware validation - not simulation or extrapolation.
