Product details
Overview
TLE2037QDRQ1 from Texas Instruments is an automotive-qualified, decompensated high-speed precision operational amplifier in an 8-pin SOIC package. It delivers 50 MHz unity-gain bandwidth, −7.5 V/µs slew rate (typ), and ultra-low input voltage noise of 2.5 nV/√Hz at 1 kHz - enabling high-fidelity signal conditioning in engine control units, battery management systems, and active filter stages.
For engineers reviewing the TLE2037QDRQ1 datasheet, TLE2037QDRQ1 pinout, TLE2037QDRQ1 application, or TLE2037QDRQ1 equivalent, key selection criteria include its minimum stable gain of 5, −40°C to 125°C operating range, 25 µV max input offset voltage, and SOIC-D package compatibility with automotive PCB layouts requiring AEC-Q100 compliance and robust ESD protection (>2 kV HBM).
Technical Context
The TLE2037QDRQ1 uses TI's Excalibur process to achieve simultaneous dc precision and ac performance: it features a decompensated internal architecture optimized for closed-loop gains ≥5, delivering 50 MHz bandwidth while maintaining 50° phase margin with 100 pF load. Its input stage employs precision-matched bipolar transistors to ensure low offset drift (0.4 µV/°C) and high CMRR (131 dB typ).
Unlike the compensated TLE2027, the TLE2037QDRQ1 trades unity-gain stability for enhanced slew rate and bandwidth - requiring external gain-setting resistors ≥4.7 kΩ to maintain stability. Its output saturation recovery circuitry enables fast settling after overdrive, critical in automotive sensor interface and PWM feedback loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 50 MHz typical - supports wideband active filters and high-speed analog front-ends without external compensation. |
| Slew Rate | −7.5 V/µs typical - enables clean 10 Vpp output at >1 MHz without slew-induced distortion. |
| Input Offset Voltage | 25 µV maximum at 25°C - ensures sub-0.01% error in precision current sensing and bridge amplifier applications. |
| Input Voltage Noise | 2.5 nV/√Hz at 1 kHz - preserves SNR in low-level sensor signal amplification (e.g., thermocouples, strain gauges). |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive environments per AEC-Q100 Grade 1. |
| Supply Voltage Range | ±4 V to ±19 V - supports dual-rail operation in 12 V and 24 V vehicle electrical systems. |
| Common-Mode Rejection | 131 dB typical - rejects engine noise and alternator ripple in differential sensor interfaces. |
Pinout & Package
Package: 8-pin SOIC (D package), surface-mount, 150 mil width, JEDEC MS-012AC compliant. Thermal resistance θJA = 101°C/W (0 LFPM).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OFFSET N1) | Offset null input | Connects to external potentiometer for fine-tuning input offset voltage in precision DC-coupled stages. |
| 2 (IN−) | Inverting input | Differential input node; high impedance (150 nA max bias current) for accurate feedback network design. |
| 3 (IN+) | Non-inverting input | Differential input node; matched to Pin 2 for optimal CMRR and offset cancellation. |
| 4 (VCC−) | Negative supply rail | Accepts −4 V to −19 V; must be decoupled with ≥0.1 µF ceramic capacitor near pin. |
| 5 (OFFSET N2) | Offset null output | Second terminal for external nulling circuit; used with Pin 1 to balance input stage mismatch. |
| 6 (OUT) | Amplifier output | Capable of ±50 mA short-circuit current; drives 600 Ω loads with <10 V swing (±10 V typical). |
| 7 (VCC+) | Positive supply rail | Accepts +4 V to +19 V; requires local 0.1 µF ceramic + 10 µF tantalum decoupling. |
| 8 (NC) | No connect | Internally unused; must remain unconnected to avoid parasitic coupling or latch-up risk. |
Key Features
| Feature | Design Value |
|---|---|
| Decompensated high-speed architecture | Enables 50 MHz bandwidth only when configured for closed-loop gain ≥5 - prevents instability in high-gain precision circuits. |
| Automotive qualification (AEC-Q100) | Validated across −40°C to 125°C with lifetime reliability testing - suitable for powertrain and chassis control modules. |
| Low 1/f noise corner | 3.3 nV/√Hz at 10 Hz - maintains accuracy in slow-slewing DC-coupled applications like battery voltage monitoring. |
| Saturation recovery circuitry | Reduces output recovery time after overdrive by >5× vs standard op-amps - critical for pulse-width modulated feedback paths. |
| High PSRR and CMRR | 144 dB supply rejection and 131 dB common-mode rejection - suppresses ripple from noisy 12 V/24 V rails and EMI. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2377QDRQ1 | Unity-gain stable (no minimum gain requirement); lower bandwidth (9 MHz); rail-to-rail output. | Better suited for low-voltage (2.7–5.5 V) systems and single-supply designs where gain flexibility is prioritized over speed. | Select when unity-gain stability and rail-to-rail output are required, and 50 MHz bandwidth is unnecessary. |
| TLE2027QDRQ1 | Compensated version; 15 MHz bandwidth; 1.7 V/µs slew rate; stable at unity gain. | Preferred for general-purpose precision amplification where stability at G = 1 is mandatory (e.g., voltage followers). | Choose when circuit topology demands unity-gain operation or when lower power (3.8 mA ICC) outweighs speed needs. |
Compared with OPA2377QDRQ1 and TLE2027QDRQ1, the TLE2037QDRQ1 uniquely balances automotive-grade reliability, 50 MHz bandwidth, and 25 µV offset - making it optimal for gain-fixed, high-dynamic-range signal chains where speed and precision coexist.

FAQ
What is the minimum closed-loop gain required for stable operation of the TLE2037QDRQ1?
The TLE2037QDRQ1 is decompensated and requires a minimum closed-loop gain of 5 for stable operation. This is explicitly stated in the datasheet's "Typical Operating Characteristics" section and Figure 3 test conditions. Operating below gain = 5 risks oscillation due to insufficient phase margin. The TLE2037QDRQ1 achieves its 50 MHz bandwidth only under this constraint - unlike the unity-gain-stable TLE2027QDRQ1.
Does the TLE2037QDRQ1 support rail-to-rail input or output?
No, the TLE2037QDRQ1 does not support rail-to-rail input or output. Its input common-mode range is specified as −10.3 V to +10.3 V with ±15 V supplies, and its output swing is ±10 V into 600 Ω (±11 V into 2 kΩ). It is a traditional bipolar-input, bipolar-output op-amp - not a rail-to-rail device. For rail-to-rail alternatives, consider the OPA2377QDRQ1 or TLV2772QDRQ1.
Is the TLE2037QDRQ1 pin-compatible with the TLE2027QDRQ1?
Yes, the TLE2037QDRQ1 is pin-compatible with the TLE2027QDRQ1 - both use the same 8-pin SOIC (D) package with identical pinout (OFFSET N1, IN−, IN+, VCC−, OFFSET N2, OUT, VCC+, NC). However, they are not functionally interchangeable without circuit review: the TLE2037QDRQ1 requires minimum gain = 5, while the TLE2027QDRQ1 is unity-gain stable. Swapping them may cause instability if gain is not adjusted.
What is the ESD rating of the TLE2037QDRQ1?
The TLE2037QDRQ1 has an ESD rating exceeding 2000 V per MIL-STD-883 Method 3015 (Human Body Model) and exceeding 200 V using the Machine Model (C = 200 pF, R = 0 Ω). This level of protection meets automotive assembly and handling requirements and reduces susceptibility to field failures caused by electrostatic discharge during module integration.
Can the TLE2037QDRQ1 drive capacitive loads directly?
The TLE2037QDRQ1 can drive moderate capacitive loads (≤100 pF) without external compensation, as confirmed by the datasheet's Figure 3 test circuit and phase margin specification (50° at unity gain with CL = 100 pF). For loads >100 pF, isolation resistance (e.g., 10–50 Ω in series with the output) or a dedicated capacitive-load driver stage is recommended to prevent peaking or oscillation.
