Product details
Overview
TLE2024AIN from Texas Instruments is a quad-channel, precision operational amplifier using the Excalibur bipolar process, delivering 2.8 MHz unity-gain bandwidth, 0.7 V/µs slew rate (±15 V), and 1000 µV max input offset voltage at 25°C. It operates across –55°C to +125°C, supports ±15 V and 5 V single-supply configurations, and features phase-reversal protection for robust low-level signal conditioning in sensor front-ends and military-grade instrumentation.
For engineers reviewing the TLE2024AIN datasheet, TLE2024AIN pinout, TLE2024AIN application, or TLE2024AIN equivalent, key selection criteria include its rail-to-rail-compatible common-mode input range (down to negative rail), low 1.4 mA total supply current (±15 V), 19 nV/√Hz input voltage noise, and ceramic DIP-14 packaging qualified for high-reliability analog signal chains.
Technical Context
The TLE2024AIN employs a complementary bipolar Excalibur process with isolated vertical PNP transistors, enabling improved unity-gain bandwidth and slew rate over legacy OP21-based designs. Its bias circuit ensures stable dc parameters across temperature and time-evidenced by ≤2 µV/°C offset drift and 0.006 µV/month long-term drift.
Phase-reversal protection prevents output inversion when inputs fall below the negative supply rail, while the common-mode input voltage range includes the negative rail (–15 V to +13.2 V at ±15 V), making it suitable for single-supply sensor interfaces without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-stage filtering or simultaneous signal conditioning of four sensor channels in one package. |
| Unity-gain bandwidth | 2.8 MHz - supports stable closed-loop operation up to ~200 kHz in gain-of-10 configurations with adequate phase margin. |
| Slew rate | 0.7 V/µs (±15 V) - handles 100 kHz full-scale sine waves up to ~1.1 V peak without distortion. |
| Input offset voltage | 1000 µV max (25°C, ±15 V) - sets baseline dc error in precision amplification; trimmed versions (TLE2024AM) offer 750 µV max. |
| Supply current | 1.4 mA total (±15 V, 25°C) - enables low-power operation in battery-backed or thermally constrained systems. |
| Operating temperature | –55°C to +125°C - qualified for aerospace, downhole, and military embedded applications requiring extended thermal resilience. |
| Input voltage noise | 19 nV/√Hz - limits detectable signal floor in 1 Hz–10 kHz band to ~0.2 µVPP (0.1–10 Hz). |

FAQ
What is the maximum supply voltage rating for the TLE2024AIN?
The TLE2024AIN has an absolute maximum supply voltage rating of ±20 V per rail. Operation at ±15 V is standard and fully characterized across the full –55°C to +125°C temperature range. Exceeding ±20 V risks permanent damage, as defined in Section 5.1 of the datasheet. The TLE2024AIN maintains specified performance at ±2 V minimum, supporting low-voltage operation in power-constrained systems.
Does the TLE2024AIN support single-supply operation?
Yes, the TLE2024AIN is explicitly specified for 5 V single-supply operation per Section 5.12 and Section 5.13 of the datasheet. With a common-mode input voltage range extending to the negative rail (GND in single-supply mode), it enables direct interfacing with grounded sensors. Output swing reaches within 0.8 V of rails under load, and phase-reversal protection remains active even when inputs dip below GND.
What is the input bias current specification for the TLE2024AIN at 25°C?
The TLE2024AIN specifies a maximum input bias current of 50 nA at 25°C under ±15 V supply conditions (Section 5.14). This value increases to 90 nA across the full –55°C to +125°C range. The low bias current minimizes voltage drop across high-impedance source networks, preserving accuracy in photodiode transimpedance or high-value resistor divider applications.
How does phase-reversal protection function in the TLE2024AIN?
The TLE2024AIN integrates internal circuitry that prevents output polarity inversion when either input falls below the negative supply rail (VCC–). Unlike unprotected op-amps that may latch or reverse output state during input overdrive, the TLE2024AIN maintains predictable behavior-critical in sensor saturation scenarios such as overpressure events in transducer interfaces. This feature is inherent to the Excalibur process design and requires no external components.
Is the TLE2024AIN pin-compatible with other TLE202xM variants in the same package?
Yes, the TLE2024AIN (CDIP-14) shares identical pinout and footprint with all other TLE2024xM variants in the J package-including TLE2024AM and TLE2024BM-as confirmed in Figure 4-6 and Table 3-3 of the datasheet. Electrical differences (e.g., offset voltage grade) do not affect physical compatibility, enabling drop-in replacement within the same family for recalibration or performance tuning.
