Product details
Overview
TLE2301INEE4 from Texas Instruments is a wide-bandwidth power operational amplifier with 3-state output control, delivering ≥1 A output current, 12 V/µs slew rate, and 8 MHz gain-bandwidth product. It features dual Class AB outputs, thermal shutdown, and operates across –40°C to 85°C for mains-line telemetering modems and high-current audio/motor driver circuits.
For engineers reviewing the TLE2301INEE4 datasheet, TLE2301INEE4 pinout, TLE2301INEE4 application, or TLE2301INEE4 equivalent, key selection criteria include 3-state enable voltage thresholds (VIH = 2 V, VIL = 0.8 V), output resistance in 3-state mode (100 kΩ), ±20 V absolute max supply, and NE-package thermal performance (ZθJA derated at 16.56 mW/°C).
Technical Context
The TLE2301INEE4 integrates two parallel Class AB output stages (OUT1/OUT2) designed to be externally tied together, enabling ≥1 A continuous output into low-impedance loads like 4 Ω mains lines. Its Excalibur process enables high-speed operation while maintaining <0.08% THD at 50 kHz.
3-state control is implemented via differential TRS1/TRS2 inputs: raising TRS1 2 V above TRS2 forces high-impedance output and reduces ICC to ≤3.5 mA; returning TRS1 within 0.8 V of TRS2 restores normal operation. Compensation terminals COMP1/COMP2 support stable unity-gain configuration with 15 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | ≥1 A continuous - drives 4 Ω mains lines per EN56065–1 utility band applications |
| Slew Rate | 12 V/µs typ - supports fast transient response in 40–90 kHz signaling without distortion |
| Gain-Bandwidth | 8 MHz typ - enables stable closed-loop operation up to ~1 MHz with adequate phase margin (30°) |
| Total Harmonic Distortion | <0.08% typ at 50 kHz - meets low-noise requirements for precision mains telemetry |
| 3-State Output Resistance | 100 kΩ typ - isolates output during standby, minimizing network loading in multi-transmitter systems |
| Input Offset Voltage | 7 mV typ at 25°C - sets DC accuracy limit for non-inverting configurations with ±5 V supplies |
| Supply Voltage Range | ±4.5 V to ±20 V - accommodates both low-power (±5 V) and high-output-voltage (±15 V) designs |
Pinout & Package
The TLE2301INEE4 uses a thermally enhanced 16-pin NE plastic DIP package with four substrate-connected VCC– terminals (pins 4, 5, 12, 13) soldered to PCB copper for ZθJA reduction. Pins 10 and 15 are high-impedance VCC– inputs for stability; pins 2 and 7 are positive supply inputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| COMP2 (1) | Compensation network | Connects to external 15 pF capacitor for unity-gain stability per Figure 5 |
| TRS2 (8) | 3-state reference input | Connected to µP ground; TRS1 referenced to this node for 3-state activation |
| IN+ (14) | Noninverting input | Accepts signals within –4 V to +1.6 V common-mode range at ±5 V supply |
| IN– (11) | Inverting input | Used with feedback network to set gain; requires matched layout for offset minimization |
| OUT1 (3), OUT2 (6) | Parallel Class AB outputs | Must be externally shorted; each sources >500 mA - combined drive meets 1 A spec |
| TRS1 (9) | 3-state enable input | Raising 2 V above TRS2 places outputs in high-Z; pulling within 0.8 V resumes operation |
| VCC+ (2,7) | Positive supply | Both pins must connect to same rail; decoupling recommended near pin 2 |
| VCC– (4,5,10,12,13,15) | Negative supply / substrate | Pins 4/5/12/13 tied to PCB copper pour; pins 10/15 connected to negative rail for stability |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM675T | Single-output, no 3-state function; 100 mA quiescent current vs. TLE2301INEE4's 2.7 mA active / 3.5 mA 3-state | Lacks integrated 3-state control - requires external MOSFET switch for high-Z mode | Choose LM675T only if 3-state is unnecessary and higher supply current is acceptable |
| OPA548TP | Higher 3 A output, wider ±30 V supply range, but no 3-state inputs; larger TO-220 package | Designed for lab-grade instrumentation, not mains-line telemetry with multi-unit coordination | Select OPA548TP when >1 A peak current or >±20 V operation is required, and board space permits TO-220 mounting |
Compared with LM675T and OPA548TP, the TLE2301INEE4 uniquely combines 1 A drive, 3-state logic interface, and NE-package thermal efficiency - making it optimal for space-constrained, multi-node mains communication systems where standby power and network loading matter.

FAQ
What is the maximum continuous output current specification for the TLE2301INEE4?
The TLE2301INEE4 delivers ≥1 A continuous output current into resistive loads such as 4 Ω mains lines, verified under recommended operating conditions (VCC± = ±5 V or ±15 V, TA = 25°C). Short-circuit current reaches 1.8 A typical at ±5 V and 3 A at ±15 V, with unlimited duration rating below 25°C ambient.
How does the 3-state functionality work on the TLE2301INEE4?
The TLE2301INEE4 implements 3-state control via differential inputs TRS1 and TRS2. Raising TRS1 2 V above TRS2 forces outputs into high-impedance mode (ro ≈ 100 kΩ) and reduces supply current to ≤3.5 mA. Normal operation resumes when TRS1 is within 0.8 V of TRS2. Both TRS pins must be referenced to the same ground plane.
What package type and thermal characteristics apply to the TLE2301INEE4?
The TLE2301INEE4 uses a thermally enhanced 16-pin NE plastic DIP package. Four substrate-connected VCC– pins (4, 5, 12, 13) are designed for soldering to large PCB copper areas, reducing junction-to-ambient thermal impedance. ZθJA derates linearly at 16.56 mW/°C above 25°C free-air temperature.
Can the TLE2301INEE4 be used in single-supply configurations?
No - the TLE2301INEE4 is specified exclusively for dual-supply operation (±4.5 V to ±20 V). Its input common-mode range, output swing, and internal biasing require symmetric positive and negative rails. Attempting single-supply use violates recommended operating conditions and risks instability or damage.
What is the purpose of the COMP1 and COMP2 pins on the TLE2301INEE4?
COMP1 (pin 16) and COMP2 (pin 1) are compensation network terminals used to stabilize closed-loop operation. Per Figure 5 in the datasheet, a 15 pF capacitor connects between them to configure the amplifier for unity-gain stability - essential for maintaining ≥30° phase margin at 8 MHz bandwidth with 20 Ω loads.
