Product details
Overview
TLV2374QDRG4Q1 from Texas Instruments is a quad-channel automotive-grade rail-to-rail input/output operational amplifier designed for precision signal conditioning in engine control units, battery management systems, and HEV/EV inverters. It delivers 3 MHz unity-gain bandwidth, 2.4 V/µs slew rate, 550 µA per channel supply current, and 39 nV/√Hz input voltage noise across –40°C to 125°C ambient operation.
For engineers reviewing the TLV2374QDRG4Q1 datasheet, TLV2374QDRG4Q1 pinout, TLV2374QDRG4Q1 application, or TLV2374QDRG4Q1 equivalent, key selection criteria include rail-to-rail I/O swing at 2.7–16 V supply, 1 pA input bias current for high-impedance sensor interfaces, AEC-Q100 Grade 1 qualification, and SOIC-14 package thermal performance (RθJA = 67°C/W).
Technical Context
The TLV2374QDRG4Q1 employs CMOS input stage architecture enabling ultra-low input bias current (1 pA typ) and high common-mode rejection (≥64 dB at 15 V), supporting direct sensing of low-level signals without phase reversal across full supply range. Its rail-to-rail output stage drives loads down to 2 kΩ while maintaining linearity up to 10 kHz with THD+N < 0.02% at AV = 1.
Designed for single-supply automotive environments, it operates from 2.7 V to 16 V - accommodating start-stop battery transients and 12-V system integration. The 3-MHz gain-bandwidth product and 2.4 V/µs slew rate enable stable closed-loop response in current-sense amplification, active filtering, and analog front-end buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports direct connection to automotive 12-V battery and start-stop transient tolerance. |
| Bandwidth (UGBW) | 3 MHz - enables stable closed-loop gain ≥10 at 300 kHz for current-sense amplifier feedback paths. |
| Slew Rate | 2.4 V/µs - ensures ≤2 µs 0.1% settling for 1-V step inputs, critical for fast transient detection in BMS. |
| Input Bias Current | 1 pA (typ) - preserves accuracy in high-impedance sensor interfaces like thermistor or strain gauge bridges. |
| Input Noise Voltage | 39 nV/√Hz - maintains SNR > 80 dB in 10-kHz bandwidth applications such as motor phase current monitoring. |
| CMRR | 67 dB min (at 15 V, 25°C) - rejects common-mode noise from noisy power rails in ECU analog signal chains. |
| Quiescent Current | 550 µA per channel - enables low-power always-on monitoring in battery management systems. |
Pinout & Package
TLV2374QDRG4Q1 is packaged in a 14-pin SOIC (D package) with nominal body size 8.65 mm × 3.91 mm and standard JEDEC MS-012AC footprint. Thermal resistance RθJA = 67°C/W enables reliable operation at 125°C ambient with moderate PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | Output (1OUT, 2OUT, 3OUT, 4OUT) | Rail-to-rail output drivers capable of sourcing/sinking ±100 mA; each supports 2-kΩ load at full swing. |
| 2, 6, 9, 13 | Inverting Input (1IN−, 2IN−, 3IN−, 4IN−) | CMOS input with 1-pA bias current; accepts common-mode voltage from GND to VDD without phase reversal. |
| 3, 5, 10, 12 | Noninverting Input (1IN+, 2IN+, 3IN+, 4IN+) | High-impedance node for reference or sensor signal routing; differential input resistance >1 TΩ. |
| 4 | VDD | Positive supply terminal - must be decoupled with ≥100 nF ceramic capacitor near pin for stability. |
| 11 | GND | Negative (lowest) power supply reference - shared return for all four channels; requires low-impedance plane. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2374DR | Industrial-grade version (non-AEC-Q100); identical electrical specs but rated only to 85°C ambient. | Not qualified for automotive safety-critical functions; unsuitable for ECU or BMS deployment. | Select TLV2374DR only for cost-sensitive non-automotive industrial control or test equipment. |
| LMV324QDRQ1 | Lower bandwidth (1 MHz), higher supply current (130 µA/channel), no rail-to-rail input - CMOS input replaced with bipolar. | Cannot support high-impedance sensor interfaces or wide common-mode range; limited to low-speed signal conditioning. | Choose LMV324QDRQ1 only when budget constraints outweigh performance needs and AEC-Q100 compliance is retained. |

FAQ
What is the maximum operating temperature range for TLV2374QDRG4Q1?
The TLV2374QDRG4Q1 is qualified per AEC-Q100 Grade 1, supporting continuous operation from –40°C to +125°C ambient temperature. This rating covers junction temperatures up to 150°C under specified thermal conditions and is validated across all electrical parameters in the datasheet's Recommended Operating Conditions table.
Does TLV2374QDRG4Q1 support rail-to-rail input and output simultaneously?
Yes, TLV2374QDRG4Q1 supports true rail-to-rail input and output operation. Its CMOS input stage accepts common-mode voltages from GND to VDD, and its output stage swings within 100 mV of both rails under 1-mA load - confirmed in the Electrical Characteristics table for VOH and VOL across 2.7 V, 5 V, and 15 V supplies.
What is the input bias current specification for TLV2374QDRG4Q1?
The TLV2374QDRG4Q1 has a typical input bias current of 1 pA at 25°C, with a maximum of 500 pA over the full –40°C to +125°C temperature range. This ultra-low value is enabled by its CMOS input architecture and is explicitly documented in Section 7.7 "Electrical Characteristics" under the IIB parameter.
Is TLV2374QDRG4Q1 pin-compatible with other TLV237x-Q1 variants?
No - TLV2374QDRG4Q1 uses a 14-pin SOIC package, while TLV2371-Q1 is in 5-pin SOT-23 and TLV2372-Q1 is in 8-pin SOIC. Pin counts, layouts, and channel count differ fundamentally; direct PCB replacement is not possible without redesign. Only functional equivalence exists within the family.
What packaging options are available for TLV2374QDRG4Q1?
TLV2374QDRG4Q1 is offered exclusively in the 14-pin SOIC (D) package with body dimensions 8.65 mm × 3.91 mm. While the TLV2374-Q1 family also supports TSSOP-14 (PW), the specific part number TLV2374QDRG4Q1 denotes the SOIC variant - confirmed in TI's official orderable addendum and device information table.
