Product details
Overview
TLV2374QDRQ1 from Texas Instruments is a quad-channel, rail-to-rail input and output automotive-grade operational amplifier designed for precision signal conditioning in engine control units, battery management systems, and HEV/EV inverters. It operates from 2.7 V to 16 V, delivers 3 MHz gain-bandwidth, 2.4 V/µs slew rate, 550 µA/channel supply current, and 39 nV/√Hz input voltage noise.
For engineers reviewing the TLV2374QDRQ1 datasheet, TLV2374QDRQ1 pinout, TLV2374QDRQ1 application, or TLV2374QDRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (–40°C to 125°C), ultra-low 1 pA input bias current, rail-to-rail CMVR up to VDD, and SOIC-14 package compatibility with high-density automotive PCB layouts.
Technical Context
The TLV2374QDRQ1 employs CMOS input stage architecture enabling high-impedance sensing and low offset drift (2 µV/°C), critical for current-sense amplification and sensor front-ends in safety-critical automotive subsystems. Its rail-to-rail common-mode input range extends to VDD without phase reversal, supporting direct connection to 12-V battery rails and start-stop system transients.
Each of the four independent op-amp channels features matched AC performance-3 MHz unity-gain bandwidth and 2.4 V/µs slew rate at 5 V-and DC specifications including 6 mV max input offset voltage over temperature, 68 dB min CMRR at 25°C, and 70 dB PSRR across supply variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports direct 12-V battery interface and start-stop operation without external regulation |
| Gain-Bandwidth Product | 3 MHz - enables stable closed-loop gain up to ~100× at 30 kHz for motor control feedback loops |
| Slew Rate | 2.4 V/µs - ensures <2 µs 0.1% settling for 1-V step inputs, suitable for fast transient detection |
| Input Bias Current | 1 pA (typ) - minimizes voltage error in high-impedance sensor interfaces (e.g., thermistors, strain gauges) |
| Input Noise Voltage | 39 nV/√Hz - preserves SNR in low-level analog signal chains such as current-sense amplifier outputs |
| Common-Mode Input Range | 0 V to VDD - eliminates need for level-shifting circuitry when monitoring signals referenced to battery ground |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464QDRQ1 | Higher supply current (550 µA → 725 µA/channel); shutdown pin included; rail-to-rail output only (not input) | Less suitable for battery-powered always-on BMS monitoring due to higher quiescent current and no rail-to-rail input | Prefer TLV2374QDRQ1 where input common-mode range to VDD is required and power budget is constrained |
| TLC2274QDRQ1 | Lower bandwidth (2.2 MHz vs 3 MHz); higher input offset (300 µV typ vs 4.5 mV typ); same 1 pA IIB | Marginally adequate for slower control loops but insufficient for 20-kHz inverter current sensing | Choose TLV2374QDRQ1 when 3-MHz GBW and fast settling are mandatory for motor control or ADAS timing |
Compared with TLV2464QDRQ1 and TLC2274QDRQ1, TLV2374QDRQ1 uniquely combines rail-to-rail input capability, 3-MHz bandwidth, and 550-µA/channel consumption in an AEC-Q100 qualified quad op-amp-making it optimal for space- and power-constrained automotive signal chains requiring full supply-rail utilization.

FAQ
What is the operating temperature range for TLV2374QDRQ1?
The TLV2374QDRQ1 is qualified per AEC-Q100 Grade 1, with guaranteed operation from –40°C to +125°C ambient temperature. This specification covers all electrical parameters-including input offset voltage, CMRR, and slew rate-across the full range, making TLV2374QDRQ1 suitable for under-hood and powertrain applications where thermal stress is extreme.
Does TLV2374QDRQ1 support rail-to-rail input voltage beyond VDD?
No. TLV2374QDRQ1 supports rail-to-rail common-mode input voltage from 0 V to VDD, inclusive. Exceeding VDD at any input pin violates Absolute Maximum Ratings and may cause permanent damage. The device does not tolerate input voltages above VDD or below GND, even momentarily.
What is the maximum capacitive load TLV2374QDRQ1 can drive stably?
TLV2374QDRQ1 maintains ≥65° phase margin with up to 100 pF capacitive load when configured as a unity-gain buffer (AV = 1), per Figure 19 in the datasheet. For loads >100 pF, external isolation resistance (e.g., 50 Ω in series with output) is recommended to preserve stability in high-frequency applications like motor current sensing.
Is TLV2374QDRQ1 pin-compatible with other TLV237x-Q1 variants?
TLV2374QDRQ1 uses a 14-pin SOIC package, while TLV2371-Q1 (5-pin SOT-23) and TLV2372-Q1 (8-pin SOIC) have different pin counts and footprints. No pin-to-pin compatibility exists between TLV2374QDRQ1 and other family members; PCB layout must be redesigned for channel count changes.
What packaging options are available for TLV2374QDRQ1?
TLV2374QDRQ1 is offered exclusively in the 14-pin SOIC (D) package with body dimensions 8.65 mm × 3.91 mm. Unlike some other TLV237x-Q1 variants, TLV2374QDRQ1 is not available in TSSOP (PW) or smaller packages-the D package provides optimal thermal performance (RθJA = 67°C/W) for automotive under-hood environments.
