Product details
Overview
TLE2301INE from Texas Instruments is a wide-bandwidth power operational amplifier with 3-state output control, delivering ≥1 A continuous output current, 12 V/µs typical slew rate, and 8 MHz gain-bandwidth product. It features dual Class AB output stages, thermal shutdown, and operates across –40°C to 85°C for mains-line telemetering modems and high-current audio drivers.
For engineers reviewing the TLE2301INE datasheet, TLE2301INE pinout, TLE2301INE application, or TLE2301INE equivalent, key selection criteria include 3-state enable logic (TRS1/TRS2), ±4.5 V to ±20 V dual-supply operation, low THD (<0.08% at 50 kHz), and NE-package thermal performance with substrate-connected VCC– terminals.
Technical Context
The TLE2301INE integrates two parallel Class AB output stages (OUT1/OUT2) internally connected for combined 1 A drive capability and uses Excalibur bipolar process technology to achieve >12 V/µs slew rate and 8 MHz unity-gain bandwidth. Its 3-state function is controlled differentially via TRS1 and TRS2 inputs, reducing supply current to <3.5 mA in high-impedance mode.
Compensation is implemented externally via COMP1/COMP2 pins using a 15 pF capacitor, supporting stable operation into reactive loads like mains-line coupling transformers. The device's four dedicated VCC– terminals (pins 4,5,12,13) are bonded to the lead frame to minimize θJA (60.4°C/W), enabling high-power dissipation in the thermally enhanced NE package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | ≥1 A continuous - supports driving low-impedance mains lines (≤4 Ω) and audio loads without external boost stages. |
| Slew Rate | 12 V/µs typ - enables faithful reproduction of fast transients in telemetering signals up to 90 kHz. |
| Gain-Bandwidth | 8 MHz typ - ensures stable closed-loop gain ≥10 up to ~800 kHz with proper compensation. |
| Total Harmonic Distortion | <0.08% typ at 50 kHz - meets EN50065-1 requirements for clean utility-band signaling. |
| 3-State Enable Threshold | TRS1 ≥ 2 V above TRS2 - provides noise-immune digital control of output impedance without external logic level shifters. |
| Input Offset Voltage | 7 mV max at 25°C - limits DC error in precision line-driver feedback paths requiring minimal trimming. |
| Supply Voltage Range | ±4.5 V to ±20 V - accommodates both low-voltage (±5 V) metering designs and higher-voltage industrial interfaces. |
Pinout & Package
The TLE2301INE uses a 16-pin thermally enhanced plastic DIP (NE package) with four substrate-connected VCC– terminals (pins 4,5,12,13) soldered to PCB copper for optimal heat dissipation (ZθJA = 60.4°C/W). Pins 10 and 15 are high-impedance VCC– inputs for stability enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (COMP2) | Compensation network terminal | Connects to external 15 pF capacitor for unity-gain stability with capacitive loads. |
| 2,7 (VCC+) | Positive supply input | Dual connection reduces supply inductance and improves PSRR at high frequencies. |
| 3 (OUT1), 6 (OUT2) | Parallel Class AB output stage outputs | Must be externally tied together to deliver full 1 A output; internal paralleling minimizes thermal mismatch. |
| 8 (TRS2), 9 (TRS1) | 3-state enable differential inputs | TRS2 referenced to µP ground; TRS1 raised ≥2 V above TRS2 activates high-Z mode (ICC < 3.5 mA). |
| 11 (IN–), 14 (IN+) | Inverting/noninverting inputs | Common-mode range extends to –14 V to +11.8 V at ±15 V supplies - supports rail-to-rail signal injection. |
| 16 (COMP1) | Compensation network terminal | Completes external RC compensation network with COMP2 and 15 pF capacitor. |
| 4,5,12,13 (VCC–) | Substrate and negative supply terminals | Direct lead-frame bonding enables PCB copper pour heat sinking - critical for >2 W dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| 3-State Output Control | Differential TRS1/TRS2 interface eliminates need for external level-shifting circuitry and reduces standby current to <3.5 mA. |
| Thermally Enhanced NE Package | Four substrate-connected VCC– pins enable direct PCB copper thermal coupling - achieves 4.64 W dissipation at 85°C case temperature. |
| Parallel Dual Output Stages | OUT1 and OUT2 internally paralleled and matched - delivers 1 A while maintaining THD <0.08% and minimizing thermal drift. |
| Excalibur Process Technology | Bipolar fabrication enables 12 V/µs slew rate and 8 MHz GBW without composite architecture - simplifies compensation design. |
| Industrial Temperature Range | Specified from –40°C to +85°C - validated for deployment in electricity meters and building automation systems exposed to ambient extremes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA547FKTWT | Higher 3 A output, wider ±30 V supply range, but no 3-state output; requires external enable logic. | Preferred for high-voltage industrial actuators; unsuitable for mains-telemetering where 3-state isolation is mandatory. | Select OPA547FKTWT only when >1 A drive and >±20 V operation are required and 3-state functionality can be implemented externally. |
| LM675T | 1.5 A output, no 3-state, lower 2.5 MHz GBW, higher 0.1% THD at 1 kHz; TO-220 package with single thermal pad. | Cost-effective for fixed-gain audio or motor drivers where dynamic output disabling is unnecessary. | Choose LM675T for non-telemetering applications needing simpler layout and lower cost, accepting reduced bandwidth and distortion performance. |
Compared with OPA547FKTWT and LM675T, the TLE2301INE uniquely combines 1 A drive, integrated 3-state control, and 8 MHz bandwidth in a thermally optimized DIP package-making it irreplaceable in EN50065-1-compliant mains signaling where output disable timing and thermal management are co-critical.

FAQ
What is the maximum continuous output current specification for the TLE2301INE?
The TLE2301INE is specified for ≥1 A continuous output current under recommended operating conditions (VCC± = ±5 V to ±20 V, TA = –40°C to 85°C). This rating is validated with both OUT1 and OUT2 connected together and accounts for thermal derating above 25°C ambient. Short-circuit current reaches 1.8 A (typ) at ±5 V and 3 A (typ) at ±15 V per pulse testing.
How does the 3-state function operate on the TLE2301INE?
The TLE2301INE enters 3-state (high-impedance output) when TRS1 is held ≥2 V above TRS2; this reduces supply current to <3.5 mA (typ). Normal operation resumes when TRS1 is within 0.8 V of TRS2. Both TRS inputs must be referenced to the same ground - TRS2 is typically tied to µP ground, and TRS1 driven by a logic signal.
Which package type is used by the TLE2301INE and why is it thermally significant?
The TLE2301INE uses a 16-pin thermally enhanced plastic DIP (NE package) with four substrate-connected VCC– terminals (pins 4,5,12,13) bonded directly to the lead frame. This construction lowers junction-to-ambient thermal resistance to 60.4°C/W, enabling 4.64 W dissipation at 85°C case temperature - essential for sustained 1 A output into low-impedance loads.
Can the TLE2301INE be used with single-supply configurations?
No - the TLE2301INE is strictly a dual-supply operational amplifier requiring symmetric or asymmetric positive and negative rails (e.g., ±5 V, ±15 V, or +15 V/–5 V). Its input common-mode range and output swing are referenced to the midpoint between VCC+ and VCC–, and it lacks rail-to-rail input or output architecture needed for true single-supply operation.
What compensation components are required for stable operation of the TLE2301INE?
The TLE2301INE requires external compensation via COMP1 and COMP2 pins using a 15 pF capacitor (as specified in Figure 5 of SLOS131). This configuration ensures unity-gain stability with capacitive loads up to 100 pF and maintains ≥30° phase margin. No series resistor is needed - the capacitor connects directly between COMP1 and COMP2.
