Product details
Overview
TLE2021CPWRG4 from Texas Instruments is a single-channel, precision operational amplifier using the Excalibur bipolar process, delivering 2 MHz unity-gain bandwidth, 0.65 V/µs slew rate, and 100 µV max input offset voltage at ±15 V supply. It operates across –55°C to +125°C, supports rail-to-rail common-mode input (including negative rail), and features phase-reversal protection-ideal for low-level signal conditioning in military-grade sensor interfaces and precision analog front-ends.
For engineers reviewing the TLE2021CPWRG4 datasheet, TLE2021CPWRG4 pinout, TLE2021CPWRG4 application, or TLE2021CPWRG4 equivalent, key selection criteria include its military-temperature-rated precision performance, low 300 µA supply current, stable dc parameters over time and temperature, and compatibility with both 5 V single-supply and ±15 V split-supply configurations.
Technical Context
The TLE2021CPWRG4 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 exceptional stability of offset voltage, supply current, and gain over temperature and years of operation.
This architecture delivers high open-loop gain (6.5 V/µV), low noise (19 nV/√Hz at 1 kHz), and robust phase margin (46° at ±15 V), while maintaining rail-inclusive common-mode input range and phase-reversal protection-critical for unbuffered sensor inputs near ground in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 300 µA max - enables ultra-low-power operation in battery-backed or thermally constrained military systems |
| Unity-Gain Bandwidth | 2 MHz - supports stable closed-loop operation up to ~1.2 MHz with adequate phase margin |
| Slew Rate | 0.65 V/µs - allows faithful reproduction of signals up to ~200 kHz at 10 Vpp without distortion |
| Input Offset Voltage | 100 µV max - ensures ≤0.1% error in 100 mV full-scale precision measurement circuits |
| Common-Mode Input Range | Includes negative rail (–15 V to +13.2 V at ±15 V) - enables direct interfacing with grounded sensors |
| Open-Loop Gain | 6.5 V/µV (136 dB) - provides high loop gain for accurate closed-loop gain setting and low gain error |
| Phase Margin | 46° at ±15 V - ensures stable unity-gain follower operation without peaking or oscillation |
Pinout & Package
TLE2021CPWRG4 is packaged in an 8-pin TSSOP (PW) with thermal pad, optimized for surface-mount reliability in high-density PCB layouts. Pin functions are validated per TI SLOS191E Rev. July 2025.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 3 | Offset Null (N1) | Connects to external potentiometer for manual offset trimming in precision DC applications |
| 4 | V– / GND | Negative supply or ground reference; supports single-supply (GND) or dual-supply (–15 V) operation |
| 5 | Offset Null (N2) | Second terminal of offset null network; used with Pin 3 for fine calibration |
| 6 | Output | Class AB output stage; drives ≥10 kΩ load with ±13.6 V swing at ±15 V supply |
| 7 | V+ | Positive supply input; rated for up to +20 V absolute maximum |
| 8 | No Connect (NC) | Internally unused; must be left floating or tied to ground per layout best practices |
Key Features
| Feature | Design Value |
|---|---|
| Phase-reversal protection | Prevents output latch-up or polarity inversion when input falls below negative rail-critical for unbuffered thermocouple or strain gauge interfaces |
| Rail-inclusive common-mode input | Accepts inputs down to V–, eliminating need for level-shifting circuitry in single-supply sensor signal chains |
| Low long-term drift | 0.005 µV/month offset drift ensures calibration stability over multi-year deployments in field instrumentation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA277UA | Lower 10 µV max offset but higher 800 µA supply current; no phase-reversal protection | Better dc accuracy in lab-grade instruments; unsuitable for unbuffered negative-rail sensor inputs | Select OPA277UA only when ultra-low offset dominates over rail-inclusive input and fault tolerance |
| LT1012ACN8#PBF | Chopper-stabilized architecture; 5 µV max offset, 0.1 µV/°C drift, but 1.2 mA supply current and 1.5 MHz bandwidth | Superior long-term stability for metrology; higher power and lower bandwidth limit dynamic response | Choose LT1012ACN8#PBF for calibration standards where drift matters more than speed or power |
Compared with OPA277UA and LT1012ACN8#PBF, TLE2021CPWRG4 uniquely balances military-temperature operation, rail-inclusive input, phase-reversal immunity, and sub-300 µA power-making it optimal for ruggedized embedded sensing where fault resilience and longevity outweigh ultimate dc precision.

FAQ
What is the maximum operating temperature range for the TLE2021CPWRG4?
The TLE2021CPWRG4 is characterized for operation from –55°C to +125°C, meeting full military temperature specifications per MIL-PRF-38535. This range is explicitly confirmed in the device comparison tables and electrical characteristics sections of the official TI datasheet SLOS191E, with all parameters-including supply current change (≤10 µA), offset voltage (≤200 µV), and output swing-guaranteed across this span.
Does the TLE2021CPWRG4 support single-supply operation?
Yes, the TLE2021CPWRG4 is fully specified for 5 V single-supply operation, with guaranteed performance including common-mode input range (0 V to 3.2 V), output swing (0.7 V to 4.3 V), and supply current (≤230 µA). The datasheet explicitly states "Specified for both 5 V single-supply and ±15 V operation" in Section 1 Features and validates parameters under VCC = 5 V in Sections 5.4 and 5.5.
What does "phase-reversal protection" mean for the TLE2021CPWRG4?
Phase-reversal protection in the TLE2021CPWRG4 prevents the output from latching to a rail or reversing polarity when either input is driven below the negative supply rail-a known failure mode in standard op-amps. This feature is implemented in silicon and verified in the functional description (Section 2), making the device safe for direct connection to unbuffered sensors like thermocouples or strain gauges that may transiently go below ground.
Is the TLE2021CPWRG4 pin-compatible with older TI op-amps like the TL071?
No, the TLE2021CPWRG4 is not pin-compatible with the TL071. While both are 8-pin SOIC/TSSOP op-amps, the TLE2021CPWRG4 uses Pins 3 and 5 for offset null adjustment (not present on TL071), and Pin 8 is NC (vs. TL071's NC or sometimes unused). Layout changes are required; substitution must be validated at circuit level-not assumed from package similarity.
What is the typical input noise voltage of the TLE2021CPWRG4 at 1 kHz?
The typical input noise voltage of the TLE2021CPWRG4 is 15 nV/√Hz at 1 kHz under ±15 V supply conditions, as documented in Section 5.7 Operating Characteristics of the TI datasheet SLOS191E. At 5 V supply, the value is 17 nV/√Hz (Section 5.5), confirming low-noise performance across both operating modes-critical for amplifying weak sensor signals without degrading SNR.
