Product details
Overview
TLE2021MP from Texas Instruments is a precision, high-speed, low-power single operational amplifier fabricated using the Excalibur complementary bipolar process. It delivers 2 MHz unity-gain bandwidth, 0.45 V/μs slew rate, and 100 μV max input offset voltage across −55°C to +125°C, enabling accurate low-level signal conditioning in military-grade analog front-ends for sensor interfaces and data acquisition systems.
For engineers reviewing the TLE2021MP datasheet, TLE2021MP pinout, TLE2021MP application, or TLE2021MP equivalent, key selection criteria include its rail-to-rail input capability (includes negative rail), phase-reversal protection, ±15 V / 5 V dual-supply operation, and stable dc performance over temperature and time-critical for precision instrumentation and ruggedized embedded control.
Technical Context
The TLE2021MP uses an isolated vertical PNP transistor architecture that improves unity-gain bandwidth and slew rate versus legacy OP21-based designs. Its bias circuit ensures minimal parameter drift with temperature and aging-evidenced by only 10 μA supply-current change over the full military temperature range.
It features phase-reversal protection to prevent output inversion when inputs go below the negative supply rail, and supports both single-supply (5 V) and split-supply (±15 V) configurations with common-mode input voltage ranges extending to the negative rail-making it suitable for ground-referenced sensor amplification without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA277MP | Lower 0.1 μV/°C offset drift but higher 1.5 mA supply current; no phase-reversal protection | Preferred for ultra-stable DC references; unsuitable for inputs near negative rail without external protection | Select OPA277MP only when sub-μV/°C drift dominates over power and rail compatibility requirements |
| LM108AMH | Higher 200 μV max VIO, lower 1.5 MHz GBW, but identical −55°C to +125°C rating and DIP-8 package | Better suited for legacy designs requiring drop-in replacement with relaxed precision demands | Choose LM108AMH when existing PCB layout must be preserved and 2× higher offset is acceptable |
Compared with OPA277MP and LM108AMH, the TLE2021MP uniquely balances military-temperature operation, rail-to-rail input, phase-reversal immunity, and sub-300 μA quiescent current-making it optimal for new designs where robustness, precision, and power efficiency are jointly critical.

FAQ
What is the maximum supply voltage rating for the TLE2021MP?
The TLE2021MP has an absolute maximum supply voltage rating of +20 V on VCC+ and −20 V on VCC−, per the official Texas Instruments SLOS191D datasheet. This allows safe operation with ±15 V supplies while accommodating transient overvoltage events up to ±20 V without damage. The recommended operating range remains ±2 V to ±20 V.
Does the TLE2021MP support single-supply operation at 5 V?
Yes, the TLE2021MP is fully specified for 5 V single-supply operation, with common-mode input voltage range extending from 0 V (GND) to 3.5 V and output swing from 0.7 V to 4.3 V (RL = 10 kΩ). Its phase-reversal protection and rail-to-rail input capability eliminate the need for level-shifting circuitry in 5 V systems.
How does the TLE2021MP achieve low input offset voltage drift over time?
The TLE2021MP achieves 0.005 μV/month typical long-term drift via its Excalibur process bias circuit and vertically isolated PNP transistors, which minimize parameter migration under thermal and electrical stress. This is validated by accelerated life testing at 150°C and extrapolated using the Arrhenius model with 0.96 eV activation energy-ensuring predictable calibration stability in deployed systems.
Is the TLE2021MP pin-compatible with other TLE202x variants like the TLE2022MP or TLE2024MP?
No, the TLE2021MP is not pin-compatible with TLE2022MP (dual) or TLE2024MP (quad). While all share the same DIP-8 package outline, the TLE2021MP is a single amplifier with dedicated offset-null pins (1 and 8), whereas TLE2022MP and TLE2024MP use different internal pin mappings and lack offset-null terminals-requiring distinct PCB layouts.
What is the purpose of Pins 1 and 8 (Offset Null N1/N2) on the TLE2021MP?
Pins 1 and 8 on the TLE2021MP provide access to the internal input stage offset nulling network. Connecting a 10-kΩ potentiometer between these pins-with its wiper grounded-allows manual adjustment of input offset voltage to <10 μV, essential for high-accuracy applications such as precision weigh scales or calibrated test equipment where factory-trimmed VIO alone is insufficient.
