Product details
Overview
TLV2371QDRG4Q1 from Texas Instruments is an AEC-Q100 Grade 1 qualified single-channel rail-to-rail input/output operational amplifier designed for automotive signal conditioning. It delivers 3 MHz gain-bandwidth, 2.4 V/µs slew rate, 550 µA supply current per channel, 39 nV/√Hz input voltage noise, and operates from 2.7 V to 16 V supply across –40°C to +125°C ambient. It is used in engine control units (ECU) for sensor signal amplification with high common-mode rejection.
For engineers reviewing the TLV2371QDRG4Q1 datasheet, TLV2371QDRG4Q1 pinout, TLV2371QDRG4Q1 application, or TLV2371QDRG4Q1 equivalent, key selection criteria include rail-to-rail I/O swing at low supply (2.7 V), ultra-low input bias current (1 pA), automotive temperature compliance, and SOT-23-5 packaging for space-constrained ECU and battery management PCB layouts.
Technical Context
The TLV2371QDRG4Q1 employs CMOS input stage architecture enabling 1 pA input bias current and rail-to-rail common-mode input range (0 V to VDD). Its internal Class AB output stage supports rail-to-rail output swing under 1 mA load while maintaining phase stability up to 100 pF capacitive load.
It features no phase reversal over full common-mode range and supports high common-mode voltage operation up to the positive supply rail-enabling direct sensing in high-side current monitor configurations without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 16 V - supports start-stop battery systems (6–16 V transients) and direct 12-V battery connection without regulation. |
| Gain-Bandwidth Product | 3 MHz - enables stable closed-loop operation up to ~200 kHz with gain ≥15, suitable for motor current feedback and analog front-end filtering. |
| Slew Rate | 2.4 V/µs - ensures <2 µs 0.1% settling for 1-V step, critical for fast transient response in HEV/EV inverter gate driver biasing. |
| Input Offset Voltage | 4.5 mV (typ), 6 mV (max over temp) - enables accurate low-level sensor signal amplification (e.g., thermistor, pressure bridge) without trimming. |
| Input Bias Current | 1 pA (typ) - preserves high-impedance sensor node integrity in ECU oxygen sensor interfaces and battery cell voltage monitoring. |
| Common-Mode Rejection | 68 dB (min at 25°C, 5 V supply) - rejects engine noise coupling on differential sensor inputs in noisy powertrain environments. |
| ESD Rating | HBM ±2000 V, CDM ±500 V - meets AEC-Q100 stress requirements for robustness in automotive assembly and field operation. |
Pinout & Package
TLV2371QDRG4Q1 is packaged in a 5-pin SOT-23 (DBV) with body size 2.90 mm × 1.60 mm, optimized for high-density automotive PCBs and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Output | Amplified signal source; rail-to-rail swing supports full dynamic range utilization into 2-kΩ loads or ADC reference buffers. |
| 2 - IN− | Inverting Input | Negative input node; high-impedance CMOS interface accepts precision feedback networks without loading error. |
| 3 - IN+ | Noninverting Input | Positive input node; accepts sensor signals directly, including high-impedance sources like thermocouples or resistive bridges. |
| 4 - GND | Negative Supply | Lowest potential reference; must be connected to system ground plane with low-inductance path to minimize noise coupling. |
| 5 - VDD | Positive Supply | Single-supply rail; accepts unregulated 12-V battery input; internal protection allows 16.5-V absolute max rating. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal acquisition from 0 V to VDD without external level-shifting, reducing BOM count in battery voltage monitors. |
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation, meeting thermal requirements of under-hood ECUs and transmission control modules. |
| 550 µA supply current per channel | Supports always-on diagnostic circuits in body control modules with sub-1-mW quiescent power at 2.7 V supply. |
| 39 nV/√Hz input voltage noise | Preserves SNR in low-amplitude sensor paths (e.g., knock sensors, cabin air quality detectors) without requiring post-amplification filtering. |
| No phase reversal over full common-mode range | Eliminates output latch-up risk when input exceeds rails-critical for fault-tolerant current sensing in HEV/EV inverters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2271QDR | Lower GBW (2.2 MHz), higher supply current (1100 µA), rail-to-rail output only (not input) | Limited common-mode range restricts use in high-side sensing; higher IQ reduces battery life in always-on BMS nodes | Choose TLC2271QDR only if lower cost is prioritized over input rail-to-rail capability and quiescent power. |
| TLV271QDR | Identical GBW (3 MHz), same IQ (550 µA), rail-to-rail output only (not input), higher offset (500 µV typ vs 4.5 mV) | Cannot accept inputs near VDD or GND-unsuitable for direct battery voltage monitoring or wide common-mode sensor interfaces | TLV271QDR may be selected for non-critical signal paths where input common-mode range is constrained by external circuitry. |

FAQ
What is the operating temperature range for TLV2371QDRG4Q1?
The TLV2371QDRG4Q1 is qualified per AEC-Q100 Grade 1, supporting continuous operation from –40°C to +125°C ambient temperature. This range covers under-hood environments in gasoline, diesel, and electric powertrains, and is validated across all electrical parameters in the datasheet's recommended operating conditions table.
Does TLV2371QDRG4Q1 support rail-to-rail input and output simultaneously?
Yes, TLV2371QDRG4Q1 supports true rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swing within 100 mV of both rails at 1-mA load). This dual capability is explicitly confirmed in the device description, features list, and electrical characteristics tables of the official TI datasheet SGLS244B.
What package type is used for TLV2371QDRG4Q1?
TLV2371QDRG4Q1 uses the 5-pin SOT-23 (DBV) package with nominal body dimensions of 2.90 mm × 1.60 mm. Pin configuration matches standard SOT-23 layout: OUT (pin 1), IN− (pin 2), IN+ (pin 3), GND (pin 4), VDD (pin 5), as documented in the "Pin Configuration and Functions" section of the TI datasheet.
Is TLV2371QDRG4Q1 pin-compatible with other TLV237x-Q1 variants?
No-TLV2371QDRG4Q1 (single-channel, SOT-23-5) is not pin-compatible with TLV2372-Q1 (dual, SOIC-8) or TLV2374-Q1 (quad, SOIC-14/TSSOP-14). The pinout, footprint, and channel count differ fundamentally; PCB redesign is required when substituting between family members.
What is the typical input offset voltage of TLV2371QDRG4Q1 over temperature?
The typical input offset voltage of TLV2371QDRG4Q1 is 4.5 mV at 25°C, with a maximum of 6 mV across the full –40°C to +125°C operating range. This value is specified in the "Electrical Characteristics" table (Section 7.7) of the TI datasheet SGLS244B under test condition VIC = VDD/2 and VO = VDD/2.
