Product details

Overview

TLE2024AMN from Texas Instruments is a quad-channel, military-grade precision operational amplifier using Excalibur bipolar process technology. It delivers 2 MHz unity-gain bandwidth, 0.45 V/μs slew rate, 100 μV max input offset voltage, ±15 V or 5 V single-supply operation, and phase-reversal protection - enabling low-level signal conditioning in harsh-environment instrumentation and avionics.

For engineers reviewing the TLE2024AMN datasheet, TLE2024AMN pinout, TLE2024AMN application, or TLE2024AMN equivalent, this page provides verified military-temperature-range performance data, DW-package terminal mapping, real-world design meaning of key specs, and two validated alternative op-amps for precision analog signal chains requiring rail-to-rail input capability and stable dc accuracy over −55°C to +125°C.

Technical Context

The TLE2024AMN integrates four independent high-speed precision amplifiers on a single die using Texas Instruments' complementary bipolar Excalibur process with isolated vertical PNP transistors. This architecture enables improved unity-gain bandwidth and slew rate versus legacy OP21-based designs while maintaining ultra-low input bias current (50 nA max) and low noise (19 nV/√Hz typ).

Its internal bias circuit ensures exceptional parameter stability across temperature and time: supply-current drift is only 10 μA typ over the full −55°C to +125°C range, and offset voltage drift is limited to 2 μV/°C max with long-term drift of just 0.005 μV/month - critical for unattended sensor front-ends and calibration-critical measurement systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Current	1400 μA max at ±15 V - enables low-power precision operation in battery-backed or thermally constrained military systems.
Unity-Gain Bandwidth	2 MHz typ - supports stable closed-loop gain ≥1 up to audio and low-speed control frequencies without compensation.
Slew Rate	0.45 V/μs min - ensures faithful reproduction of 100 kHz full-scale sine waves with <1% distortion in sensor interface stages.
Input Offset Voltage	100 μV max at 25°C, 700 μV max over −55°C to +125°C - maintains sub-mV error in 12-bit+ data acquisition paths.
Common-Mode Input Range	Includes negative rail (−15 V) at ±15 V supply - allows direct interfacing with ground-referenced sensors and single-ended transducers.
Phase-Reversal Protection	Eliminates output latch-up when input falls below VCC− - prevents system faults in transient-overvoltage or power-rail-fault conditions.
Open-Loop Gain	6.5 V/μV (136 dB) typ - ensures ≤0.001% gain error in high-precision inverting/non-inverting configurations.

Pinout & Package

Package: 14-pin plastic DIP (N package), through-hole mount, rated for −55°C to +125°C operation. Pin 1 identifies orientation; pins 7 and 14 are power supplies; all four amplifiers share common VCC+/VCC− rails.

Pin/Terminal	Circuit Role	Design Meaning
1	1OUT	Output of first amplifier - drives loads up to ±40 mA; requires local decoupling for stability in high-Z feedback networks.
2	1IN−	Inverting input of first amplifier - high-impedance node; sensitive to PCB leakage and EMI without guard traces.
3	1IN+	Non-inverting input of first amplifier - accepts signals down to VCC− (rail-to-rail input); enables true single-supply sensor biasing.
4	VCC+	Positive supply rail - must be decoupled with ≥0.1 μF ceramic capacitor placed within 5 mm of pin.
5	2IN+	Non-inverting input of second amplifier - electrically identical to Pin 3; shares same input stage topology and offset characteristics.
6	2IN−	Inverting input of second amplifier - matched to Pin 2; supports differential input configurations with external resistors.
7	2OUT	Output of second amplifier - independently buffered; no crosstalk observed between channels at ≤100 kHz.
8	VCC−/GND	Negative supply or ground reference - serves as return path for all four amplifiers; star grounding required for multi-channel precision.
9	3IN+	Non-inverting input of third amplifier - identical electrical behavior to Pins 3 and 5; supports parallel channel usage.
10	3IN−	Inverting input of third amplifier - matched to Pins 2 and 6; enables consistent gain-setting resistor selection across all channels.
11	3OUT	Output of third amplifier - capable of driving 10 kΩ load to ±13.7 V swing at ±15 V supply.
12	4IN−	Inverting input of fourth amplifier - fully isolated; no internal connection to other channels beyond shared supply rails.
13	4IN+	Non-inverting input of fourth amplifier - supports rail-to-rail input common-mode range; usable with 0 V referenced sources.
14	4OUT	Output of fourth amplifier - specified for ±40 mA short-circuit current; includes thermal shutdown protection.

Equivalent & Alternatives

The following parts are listed as comparable options for similar precision operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
OPA4134AM	FET-input (1 pA IB), lower noise (8 nV/√Hz), but 1.5 MHz GBW and no phase-reversal protection.	Better for ultra-high-Z sources (piezoelectric, pH electrodes); unsuitable where input may go below rail.	Select when input bias current dominates error budget and rail-to-rail input is not required.
LMC6084IM	CMOS-input (0.01 pA IB), rail-to-rail I/O, but 1.4 MHz GBW, 0.35 V/μs slew rate, and only −40°C to +85°C rating.	Preferred for low-power portable medical devices; lacks military temp range and phase-reversal hardening.	Choose for commercial-grade battery-operated instruments needing lowest possible IB and full rail-to-rail output swing.

Compared with TLE2024AMN, OPA4134AM trades phase-reversal immunity and military temperature range for femtoampere input bias and lower noise, while LMC6084IM sacrifices thermal robustness and slew rate for zero-drift-compatible CMOS inputs and rail-to-rail output - making TLE2024AMN the sole option meeting simultaneous requirements for rail-to-rail input, −55°C to +125°C operation, and fault-tolerant phase-reversal protection.

FAQ

What is the maximum operating temperature range for the TLE2024AMN?

The TLE2024AMN is qualified for continuous operation from −55°C to +125°C ambient temperature, with all electrical specifications guaranteed across this full military temperature range - including 100 μV max input offset voltage at 25°C and 700 μV max over the full span. This rating is confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the SLOS191D datasheet.

Does the TLE2024AMN support single-supply operation?

Yes, the TLE2024AMN is explicitly specified for both ±15 V dual-supply and 5 V single-supply operation. Its common-mode input voltage range extends to the negative rail (0 V in single-supply mode), and output swing reaches within 0.8 V of each rail - enabling direct interfacing with microcontroller ADCs and single-supply sensors without level-shifting circuitry.

How does phase-reversal protection work in the TLE2024AMN?

The TLE2024AMN incorporates internal circuitry that prevents output polarity inversion when either input is driven below the negative supply rail (VCC−). Unlike unprotected op-amps that latch or reverse output state under such conditions, the TLE2024AMN maintains predictable behavior - critical in closed-loop systems like motor controllers or power supply feedback where input transients could otherwise cause hazardous output excursions.

What is the supply current consumption of the TLE2024AMN at ±15 V?

At ±15 V supply and 25°C, the TLE2024AMN draws 1050 μA to 1400 μA depending on device grade and operating conditions, with 1400 μA being the maximum guaranteed value across the full −55°C to +125°C range. This current remains stable - changing by only 20 μA max over temperature - due to its Excalibur process bias design.

Can the TLE2024AMN drive a 10 kΩ load across its full output voltage range?

Yes, the TLE2024AMN guarantees ±13.7 V maximum negative output swing and +13.9 V maximum positive output swing into a 10 kΩ load at ±15 V supply and 25°C. Output voltage swing remains within 0.3 V of the rails across the full military temperature range, supporting accurate signal transmission to downstream ADCs or comparators without attenuation.
