Product details
Overview
TLE2022IDR from Texas Instruments is a dual-channel, precision operational amplifier using the Excalibur bipolar process, delivering 2 MHz unity-gain bandwidth, 0.65 V/µs slew rate, and 150 µV max input offset voltage at ±15 V supply - optimized for low-level signal conditioning in military-grade instrumentation and sensor front-ends.
For engineers reviewing the TLE2022IDR datasheet, TLE2022IDR pinout, TLE2022IDR application, or TLE2022IDR equivalent, key selection criteria include its rail-to-rail input capability (including negative rail), phase-reversal protection, stable 300 µA max supply current over –55°C to +125°C, and compatibility with both single-5V and split-±15V operation.
Technical Context
The TLE2022IDR employs a complementary bipolar Excalibur process with isolated vertical PNP transistors, enabling higher unity-gain bandwidth and slew rate than legacy OP21-based amplifiers. Its bias circuit ensures minimal parameter drift across temperature and time.
It features phase-reversal protection that prevents output inversion when inputs fall below the negative supply rail, and supports common-mode input voltage ranges extending to the negative rail - critical for single-supply transducer interfacing and precision difference amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables matched-pair signal paths in instrumentation, e.g., differential input stages or dual feedback loops. |
| Unity-gain bandwidth | 2 MHz - supports stable closed-loop operation up to ~1.7 MHz with gain ≥ 1, suitable for anti-aliasing filters and active sensor conditioning. |
| Slew rate | 0.65 V/µs - allows clean 10 kHz full-scale sine output at 2 Vpp without distortion under ±15 V supply. |
| Input offset voltage | 150 µV max (±15 V, 25°C) - enables sub-1 mV error in 10 V full-scale measurement systems without trimming. |
| Supply current | 300 µA max per channel (±15 V) - achieves precision performance while consuming < 1 mA total, ideal for power-constrained military modules. |
| Operating temperature | –55°C to +125°C - qualified for MIL-STD-883 Class B environments including avionics, downhole tools, and vehicle control units. |
| Input bias current | 50 nA max - permits use with high-impedance sources (e.g., piezoelectric sensors or pH electrodes) without significant DC error. |
Pinout & Package
Package: SOIC-8 (D package), 8-pin surface-mount plastic small-outline integrated circuit - compatible with standard reflow profiles and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel 1) | Accepts inverted-phase signal; internal phase-reversal protection prevents latch-up if driven below V–. |
| 2 | Non-inverting input (Channel 1) | Accepts reference or sensor signal; common-mode range includes V–, enabling true single-supply operation. |
| 3 | Output (Channel 1) | Capable of ±13.6 V swing into 10 kΩ load at ±15 V supply - supports wide dynamic range analog outputs. |
| 4 | V– (Negative supply) | Reference for dual-supply operation; also serves as ground reference in single-5V configurations (V– = GND). |
| 5 | Non-inverting input (Channel 2) | Independent input path; matched dc specs enable dual-channel synchronous acquisition. |
| 6 | Inverting input (Channel 2) | Phase-reversal protected like Pin 1 - safe for unbuffered sensor inputs crossing rail boundaries. |
| 7 | Output (Channel 2) | Electrically isolated from Channel 1 output; no crosstalk specified - suitable for independent signal chains. |
| 8 | V+ (Positive supply) | Accepts 5 V (single) or +15 V (dual); internal regulation maintains stable bias under supply ripple ≤ 100 mVpp. |
Key Features
| Feature | Design Value |
|---|---|
| Phase-reversal protection | Prevents catastrophic output inversion when either input drops below V– - eliminates need for external clamping diodes in transducer interfaces. |
| Rail-to-rail input (V– inclusive) | Enables direct connection of grounded-sensor outputs (e.g., thermocouples, strain gauges) without level-shifting circuitry. |
| Low long-term drift | 0.006 µV/month - ensures calibration stability over 10+ years in sealed military enclosures without recalibration. |
| High open-loop gain | 6.5 V/µV (136 dB) - delivers < 0.001% gain error in unity-gain buffer configurations at 10 kΩ load. |
| Low noise voltage | 19 nV/√Hz at 1 kHz - preserves SNR in 20-bit ADC front-ends with bandwidths up to 100 kHz. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2277UA | Lower VIO (10 µV typ), higher cost, SOIC-8 but not MIL-temp rated (–40°C to +85°C only) | Lacks military temperature qualification; unsuitable for embedded systems requiring –55°C startup. | Select only for commercial-grade systems where ultra-low offset outweighs temp range and cost constraints. |
| LMC6082IMX | CMOS input (0.01 pA IIB), lower supply current (120 µA), but only 1.3 MHz GBW and no phase-reversal protection | No rail-to-rail input near V–; requires external protection for sensors crossing ground. | Prefer for ultra-high-Z sources where bias current dominates error, but verify input voltage limits before deployment. |
Compared with OPA2277UA and LMC6082IMX, the TLE2022IDR uniquely combines MIL-temperature operation, phase-reversal immunity, and 2 MHz bandwidth in a cost-effective SOIC-8 package - making it the only drop-in solution for ruggedized dual-channel precision signal chains requiring guaranteed performance from –55°C.

FAQ
What is the maximum operating temperature range for the TLE2022IDR?
The TLE2022IDR is characterized for operation from –55°C to +125°C, meeting MIL-STD-883 requirements for extended temperature performance. This range is explicitly confirmed in Section 3 (Device Comparison Tables) and Section 5.3 (Recommended Operating Conditions) of the official TI datasheet SLOS191E, and applies to all M-suffix variants including TLE2022IDR.
Does the TLE2022IDR support single-supply operation?
Yes, the TLE2022IDR is fully specified for 5 V single-supply operation, with common-mode input voltage range extending to the negative rail (0 V when V– = GND) and output swing to within 0.95 V of each rail. These capabilities are documented in Sections 5.4 and 5.8 of the datasheet under "Electrical Characteristics" at VCC = 5 V.
What is the input offset voltage specification for the TLE2022IDR at ±15 V supply?
At ±15 V supply and 25°C, the TLE2022IDR has a maximum input offset voltage of 150 µV for the 'M' grade (TLE2022M), as stated in Table 5-10 (Electrical Characteristics TLE2022xM, VCC = ±15 V). The 'IDR' suffix denotes the SOIC-8 packaging of the TLE2022M variant.
Is phase-reversal protection active on both channels of the TLE2022IDR?
Yes, phase-reversal protection is implemented on both amplifier channels, as confirmed in the Functional Description (Section 2): "these devices offer phase-reversal protection circuitry that eliminates an unexpected change in output states when one of the inputs is less than the negative supply rail." Pin-level behavior is identical for Channels 1 and 2 per Figure 4-2 (JG package) and functional equivalence across channels.
What package type does the TLE2022IDR use, and is it RoHS-compliant?
The TLE2022IDR uses an 8-pin SOIC (D package), as indicated by the 'DR' suffix per TI's packaging nomenclature. It is RoHS-compliant and lead-free, consistent with TI's corporate compliance policy effective July 2006 and verified in the "Mechanical, Packaging, and Orderable Information" section (Section 11) of SLOS191E.
