Product details
Overview
TLV2254QDRG4Q1 from Texas Instruments is a quad-channel, rail-to-rail output, micropower operational amplifier qualified for automotive applications (AEC-Q100 Grade 1). It delivers 19 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, 34 µA per channel supply current, and operates from 2.7 V to 16 V. It enables high-precision signal conditioning in battery-powered automotive sensor interfaces and low-voltage data acquisition systems.
For engineers reviewing the TLV2254QDRG4Q1 datasheet, TLV2254QDRG4Q1 pinout, TLV2254QDRG4Q1 application, or TLV2254QDRG4Q1 equivalent, key selection criteria include its rail-to-rail output swing, 850 µV max input offset voltage (A-grade), −40°C to 125°C operating range, SOIC-14 package, and compatibility with single-supply 3 V/5 V systems interfacing to ADCs.
Technical Context
The TLV2254QDRG4Q1 implements a CMOS-based Advanced LinCMOS™ input stage delivering ultra-low input bias current (1 pA typ) and high input impedance (>10¹² Ω), making it suitable for high-impedance source amplification such as piezoelectric transducers. Its rail-to-rail output stage supports full dynamic range utilization across 2.7–16 V supplies.
It features fully specified operation over automotive temperature range (−40°C to 125°C), ESD protection exceeding 2000 V (MIL-STD-883), and common-mode input voltage range extending to the negative rail - enabling direct ground-referenced sensing without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single-supply operation down to 3 V for battery-powered automotive modules. |
| Input Offset Voltage (max) | 850 µV at TA = 25°C - enables precision DC-coupled amplification without external trimming in sensor front-ends. |
| Supply Current (per channel) | 34 µA typ at 3 V - allows four-channel operation at <136 µA total, critical for always-on vehicle subsystems. |
| Input Bias Current | 1 pA typ - preserves signal integrity when amplifying from high-impedance sources like pH electrodes or photodiodes. |
| Input Voltage Noise | 19 nV/√Hz at f = 1 kHz - provides low-noise signal conditioning for analog sensor outputs before ADC sampling. |
| Output Swing | Rail-to-rail - delivers full-scale output into 10 kΩ load, maximizing SNR when driving SAR or delta-sigma ADC inputs. |
| Common-Mode Input Range | Includes negative rail (VDD−) - permits direct interface to ground-referenced sensors without input biasing resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2254AQDRQ1 | 850 µV max VIO (vs. 1500 µV for TLV2254QDRG4Q1); otherwise identical specs and pinout. | Required where tighter DC accuracy is needed (e.g., closed-loop current sensing), not for general-purpose buffering. | Select TLV2254AQDRQ1 only if VIO ≤850 µV is mandatory; TLV2254QDRG4Q1 suffices for most automotive sensor interfaces. |
| LMV324QDRQ1 | Higher supply current (130 µA/ch), no rail-to-rail output, wider VIO range (±3 mV), lower cost. | Suitable for non-critical, higher-power subsystems (e.g., lighting control feedback) where rail-to-rail swing is unnecessary. | Choose LMV324QDRQ1 for cost-sensitive, non-precision applications; TLV2254QDRG4Q1 is preferred for low-noise, low-power, rail-to-rail needs. |
Compared with TLV2254AQDRQ1, TLV2254QDRG4Q1 trades 650 µV higher VIO for broader availability and identical micropower, noise, and automotive qualification. Against LMV324QDRQ1, it delivers 75% lower supply current, rail-to-rail output, and 4× lower input voltage noise - justifying its use in precision battery-constrained systems.

FAQ
What is the maximum operating temperature range for TLV2254QDRG4Q1?
The TLV2254QDRG4Q1 is qualified for automotive Grade 1 operation, with a guaranteed operating free-air temperature range of −40°C to +125°C. All electrical specifications - including input offset voltage, supply current, and output swing - are fully characterized across this range, making TLV2254QDRG4Q1 suitable for under-hood and cabin applications where thermal stability is critical.
Does TLV2254QDRG4Q1 support true rail-to-rail input common-mode range?
TLV2254QDRG4Q1 supports rail-to-rail *output* swing but its common-mode input voltage range extends only to VDD− and up to VDD+ −1.3 V (e.g., 0 V to 1.7 V at 3 V supply). It does *not* accept inputs at the positive rail. However, inclusion of the negative rail enables direct ground-referenced sensor interfacing without level-shifting - a key advantage over many competing op-amps.
What is the supply current consumption of TLV2254QDRG4Q1 at 5 V operation?
At VDD = 5 V and TA = 25°C, TLV2254QDRG4Q1 draws 140 µA typical total supply current (35 µA per channel). Over the full −40°C to 125°C range, maximum total IDD is 300 µA. This micropower performance enables four-channel operation in always-on automotive modules while maintaining low self-heating and extended battery life.
Is TLV2254QDRG4Q1 pin-compatible with TLV2254AQDRQ1?
Yes, TLV2254QDRG4Q1 and TLV2254AQDRQ1 share identical SOIC-14 (D) packaging, pinout, and footprint. They differ only in input offset voltage grade (1500 µV max vs. 850 µV max) and top-side marking (TLV2254Q1 vs. TLV2254AQ1). No PCB redesign is required when substituting between these variants - only validation of system-level DC accuracy requirements.
What packaging and assembly standards apply to TLV2254QDRG4Q1?
TLV2254QDRG4Q1 is supplied in a Pb-free, RoHS-compliant SOIC-14 (D) package conforming to JEDEC MS-012AC. It is qualified for reflow soldering per J-STD-020, with a peak reflow temperature of 260°C (10 seconds at 1.6 mm from case). The device meets AEC-Q100 stress test requirements for automotive use, including temperature cycling, humidity bias, and mechanical shock.
