Product details
Overview
TLE2021AQDRG4Q1 from Texas Instruments is a single-channel, AEC-Q100 qualified automotive precision operational amplifier in an 8-pin SOIC package. It delivers 2 MHz unity-gain bandwidth, 0.45 V/μs minimum slew rate, and 100 μV maximum input offset voltage across –40°C to +125°C, enabling high-accuracy signal conditioning in battery management systems and automotive body electronics.
For engineers reviewing the TLE2021AQDRG4Q1 datasheet, TLE2021AQDRG4Q1 pinout, TLE2021AQDRG4Q1 application, or TLE2021AQDRG4Q1 equivalent, key selection criteria include its rail-to-rail input capability (including negative rail), phase-reversal protection, low 300 μA supply current, and dual-supply (±15 V) or single-supply (5 V) operation compatibility.
Technical Context
The TLE2021AQDRG4Q1 uses a proprietary Texas Instruments bipolar process optimized for stable dc performance over temperature and time. Its bias circuitry ensures minimal supply-current change across –40°C to +125°C and supports precision operation in both single-supply (5 V) and split-supply (±15 V) configurations.
It features phase-reversal protection that prevents output state inversion when an input falls below the negative supply rail, and its common-mode input range includes the negative rail - a critical capability for low-level signal amplification in automotive sensor interfaces and current-sense circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply current | 300 μA max - enables ultra-low-power operation in always-on automotive modules. |
| Unity-gain bandwidth | 2 MHz typical - supports medium-speed closed-loop control and sensor signal amplification up to ~1 MHz. |
| Slew rate | 0.45 V/μs min - ensures faithful reproduction of fast transients in motor control feedback paths. |
| Input offset voltage | 100 μV max - provides <1 mV error at 100× gain, critical for precision current sensing in BMS. |
| Common-mode input range | Includes negative rail - allows direct interface with ground-referenced sensors without level-shifting. |
| Operating temperature | –40°C to +125°C - fully qualified for under-hood and powertrain applications per AEC-Q100 Grade 1. |
| ESD protection | >1000 V per MIL-STD-883 Method 3015 - enhances robustness in manufacturing and field environments. |
Pinout & Package
Package: D (SOIC, 8-pin), surface-mount, 3.9 mm × 4.9 mm footprint, standard JEDEC MS-012AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OFFSET N1 | External offset null adjustment terminal - used with potentiometer to trim input offset voltage to near zero. |
| 2 | –IN | Inverting input - primary feedback node in standard op-amp configurations (e.g., inverting amplifier, transimpedance). |
| 3 | +IN | Noninverting input - connects to reference or sensor signal in noninverting amplifier or comparator applications. |
| 4 | V– | Negative power supply - must be connected to lowest potential (e.g., GND in single-supply, –15 V in dual-supply). |
| 5 | NC | No connection - internally unconnected; must be left floating per datasheet. |
| 6 | OUT | Amplified output - drives loads up to ±20 mA; output swing reaches within 0.7 V of rails at 5 V supply. |
| 7 | V+ | Positive power supply - supplies highest potential (e.g., 5 V or +15 V); decoupling capacitor required. |
| 8 | OFFSET N2 | Second external offset null terminal - completes the nulling network with Pin 1 and external resistor/potentiometer. |
Key Features
| Feature | Design Value |
|---|---|
| Phase-reversal protection | Prevents output latch-up or polarity flip when input drops below V–, eliminating need for external clamping diodes in sensor front-ends. |
| Rail-inclusive common-mode range | Enables direct amplification of signals referenced to system ground (e.g., shunt-based current sensing), reducing BOM and layout complexity. |
| AEC-Q100 Grade 1 qualification | Validated for automotive use across full –40°C to +125°C ambient range, supporting safety-critical body and powertrain subsystems. |
| Low input bias current | 50 nA max - minimizes voltage error across high-impedance sources (e.g., thermistors, piezoelectric sensors) without requiring guard traces. |
| Stable parameters over time/temperature | Drift-limited design ensures long-term calibration integrity in battery monitoring and ADAS sensor signal chains over vehicle lifetime. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AQPWRQ1 | Zero-drift architecture; 12 μV max offset; 0.17 μV/°C drift; higher 350 μA supply current. | Better dc accuracy for ultra-low-drift requirements; less suitable for high-slew-rate transients. | Select when long-term offset stability dominates over speed and power. |
| LM7332QMA/NOPB | Higher slew rate (15 V/μs); dual-channel; 1.5 mA supply current; no offset null pins. | Superior dynamic performance for active filtering and fast control loops; higher power consumption limits always-on use. | Select when bandwidth and drive strength outweigh low-power and trimming needs. |
Compared with OPA2333AQPWRQ1 and LM7332QMA/NOPB, the TLE2021AQDRG4Q1 uniquely balances low power (300 μA), trimmable offset (via Pins 1/8), and automotive-grade robustness - making it optimal for cost-sensitive, precision analog front-ends where manual calibration and thermal stability are prioritized.

FAQ
What is the maximum operating temperature range for the TLE2021AQDRG4Q1?
The TLE2021AQDRG4Q1 is AEC-Q100 Grade 1 qualified and operates across –40°C to +125°C ambient temperature. This rating is validated per automotive standards and applies to all electrical specifications in the datasheet, ensuring reliable performance in under-hood and powertrain applications where thermal stress is severe.
Does the TLE2021AQDRG4Q1 support single-supply operation?
Yes, the TLE2021AQDRG4Q1 is fully specified for 5 V single-supply operation. Its common-mode input range extends to the negative rail (0 V), and output swings to within 0.7 V of the rails - enabling direct interfacing with microcontroller ADCs and ground-referenced sensors without level-shifting circuitry.
How is offset voltage adjusted on the TLE2021AQDRG4Q1?
The TLE2021AQDRG4Q1 provides dedicated offset null terminals (Pins 1 and 8) for external trimming. A 10 kΩ potentiometer is connected between these pins, with its wiper grounded; adjusting the potentiometer nulls input offset voltage to ≤10 μV in production calibration, improving absolute accuracy in precision measurement systems.
What packaging and lead finish does the TLE2021AQDRG4Q1 use?
The TLE2021AQDRG4Q1 is supplied in an 8-pin SOIC (D package) with matte tin lead finish, RoHS-compliant and compatible with standard SnPb and lead-free reflow profiles. The package dimensions are 3.9 mm × 4.9 mm × 1.75 mm (height), meeting JEDEC MS-012AC mechanical specifications.
Is phase-reversal protection active in both single- and dual-supply configurations of the TLE2021AQDRG4Q1?
Yes, phase-reversal protection is inherent to the TLE2021AQDRG4Q1's internal architecture and functions identically in both 5 V single-supply and ±15 V dual-supply modes. It prevents output polarity inversion when either input falls below the negative supply rail - a critical safeguard for sensor inputs exposed to transients or cold-junction offsets.
