Product details
Overview
TLE2037AQDRG4Q1 from Texas Instruments is a decompensated, high-speed, precision operational amplifier optimized for automotive applications. It delivers 50 MHz unity-gain bandwidth, −7.5 V/µs slew rate (typ), and 25 µV max input offset voltage at 25°C, enabling high-fidelity signal conditioning in engine control units and battery management systems.
For engineers reviewing the TLE2037AQDRG4Q1 datasheet, TLE2037AQDRG4Q1 pinout, TLE2037AQDRG4Q1 application, or TLE2037AQDRG4Q1 equivalent, key selection criteria include minimum closed-loop gain ≥5 for stability, ±4 V to ±19 V supply operation, and −40°C to 125°C automotive temperature range compliance.
Technical Context
The TLE2037AQDRG4Q1 uses TI's Excalibur process to achieve simultaneous dc precision and ac performance. Its decompensated architecture enables wide bandwidth but requires closed-loop gain ≥5 to maintain 50° phase margin and avoid oscillation under capacitive loads up to 100 pF.
It features saturation recovery circuitry for fast overdrive recovery, rail-to-rail output swing capability (±13.5 V into 2 kΩ), and robust ESD protection (>2000 V HBM, >200 V MM), making it suitable for noisy automotive sensor front-ends and active filter stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 50 MHz typ - supports stable closed-loop operation up to 50 MHz with AV ≥ 5 |
| Slew Rate | −7.5 V/µs typ - enables accurate reproduction of fast transients in motor control feedback |
| Input Offset Voltage | 25 µV max at 25°C - ensures sub-mV error in precision current sensing over temperature |
| Supply Voltage Range | ±4 V to ±19 V - compatible with 12 V and 24 V automotive battery rails with headroom |
| Operating Temperature | −40°C to 125°C - qualified per AEC-Q100 for under-hood and powertrain use |
| Input Noise Voltage | 2.5 nV/√Hz at 1 kHz - preserves SNR in low-level sensor amplification (e.g., thermocouple, strain gauge) |
| Large-Signal Voltage Gain | 19 V/µV typ into 600 Ω - provides >100 dB open-loop gain for high-accuracy closed-loop configurations |
Pinout & Package
Package: 8-pin SOIC (D package), surface-mount, 3.9 mm × 4.9 mm footprint, 1.75 mm height, RoHS-compliant.

| 3 (IN+) | Non-Inverting Input | Differential input node; common-mode range extends to ±10.2 V at full temperature |
| 4 (VCC−) | Negative Supply Rail | Accepts −4 V to −19 V; must be decoupled locally for noise immunity |
| 5 (OFFSET N2) | Offset Null Input 2 | Second terminal of offset null network; used with Pin 1 for calibration |
| 6 (OUT) | Amplifier Output | Capable of ±13.5 V swing into 2 kΩ; drives ADC inputs or downstream buffers directly |
| 7 (VCC+) | Positive Supply Rail | Accepts +4 V to +19 V; supplies internal bias and output stage |

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, 0.02 µV/°C drift, 350 kHz GBW, rail-to-rail I/O | Better dc accuracy and low-frequency stability; lower bandwidth limits dynamic response | Select for ultra-low drift in battery-powered BMS monitoring where speed <100 kHz suffices |
| LM7332QMA/NOPB | 16 MHz GBW, ±60 V/µs slew, dual-channel, 2.1 mA/ch supply current | Higher drive strength and dual configuration; higher noise (8 nV/√Hz) and larger offset (150 µV max) | Select when dual-channel operation and high output current (±80 mA) are required in motor driver feedback |
Compared with OPA2333AQPWRQ1 and LM7332QMA/NOPB, the TLE2037AQDRG4Q1 uniquely balances 50 MHz bandwidth, 25 µV max offset, and automotive qualification-making it optimal for high-speed, high-accuracy analog signal paths where both precision and speed are non-negotiable.

FAQ
What is the minimum closed-loop gain required for stable operation of the TLE2037AQDRG4Q1?
The TLE2037AQDRG4Q1 is decompensated and requires a minimum closed-loop gain of 5 (AV ≥ 5) to ensure stability and maintain ≥50° phase margin. Operating at unity gain will cause oscillation due to insufficient internal compensation. This constraint is explicitly stated in the datasheet's "Recommended Operating Conditions" and Figure 3 test circuit notes.
Does the TLE2037AQDRG4Q1 support rail-to-rail output swing?
The TLE2037AQDRG4Q1 does not provide rail-to-rail output swing. Its maximum output voltage swing is ±13.5 V into 2 kΩ with ±15 V supplies, and ±10 V into 600 Ω. The output cannot reach within ~1.5 V of either supply rail, limiting its use in low-voltage single-supply applications without level-shifting.
Is the TLE2037AQDRG4Q1 pin-compatible with the TLE2027AQDRQ1?
Yes, the TLE2037AQDRG4Q1 is pin-compatible with the TLE2027AQDRQ1. Both devices use the same 8-pin SOIC (D) package with identical pinout (OFFSET N1, IN−, IN+, VCC−, OFFSET N2, OUT, VCC+, NC). However, they differ in compensation: TLE2027AQDRQ1 is unity-gain stable (15 MHz GBW), while TLE2037AQDRG4Q1 is decompensated (50 MHz GBW, AV ≥ 5 required).
What is the purpose of Pins 1 and 5 (OFFSET N1 and OFFSET N2) on the TLE2037AQDRG4Q1?
Pins 1 and 5 on the TLE2037AQDRG4Q1 form the offset null interface. Connecting a 10 kΩ potentiometer between these pins-with its wiper tied to VCC−-allows manual adjustment of input offset voltage to ≤1 µV. This feature is essential for applications demanding ultra-low dc error, such as precision weigh scales or medical sensor front-ends.
How does the TLE2037AQDRG4Q1 handle input overvoltage conditions?
The TLE2037AQDRG4Q1 specifies a differential input voltage limit of ±1.2 V. Exceeding this risks excessive input current flow unless external series resistors are used. Its absolute maximum ratings allow input voltages from VCC− to VCC+, but sustained overvoltage beyond ±1.2 V differentially may degrade long-term reliability or cause latch-up if not properly current-limited per datasheet Note 2.
