Product details
Overview
TLV2254AQDRG4Q1 from Texas Instruments is a quad-channel, rail-to-rail output, micropower operational amplifier qualified for automotive applications (AEC-Q100 Grade 1, −40°C to +125°C). It delivers 19 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, 850 µV max input offset voltage at 25°C, and operates from 2.7 V to 16 V supply. It is used in precision sensor signal conditioning and low-power ADC interfacing in battery-powered vehicle subsystems.
For engineers reviewing the TLV2254AQDRG4Q1 datasheet, TLV2254AQDRG4Q1 pinout, TLV2254AQDRG4Q1 application, or TLV2254AQDRG4Q1 equivalent, key selection criteria include its rail-to-rail output swing, 34 µA per channel quiescent current, automotive temperature range, low-noise performance, and SOIC-14 package compatibility with legacy TLV2324 layouts.
Technical Context
The TLV2254AQDRG4Q1 employs Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω), rail-to-rail output swing (within 10 mV of rails at light load), and common-mode input range extending to the negative rail. Its CMOS input stage enables ultra-low input bias current (1 pA typ) and low input offset voltage drift (0.5 µV/°C).
It features a gain-bandwidth product of 0.187 MHz at 3 V and 0.2 MHz at 5 V, slew rate of 0.07–0.12 V/µs (depending on supply), and phase margin of 63° - optimized for stable unity-gain buffer and low-frequency closed-loop configurations in automotive analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports wide automotive battery range including cold-crank (6 V) and load-dump (16 V) conditions. |
| Quiescent Current (per channel) | 34 µA typ - enables multi-channel operation in always-on vehicle modules without excessive battery drain. |
| Input Offset Voltage (max) | 850 µV at TA = 25°C - ensures <1 LSB error when driving 12-bit ADCs with 3.3 V reference. |
| Input Bias Current (typ) | 1 pA - preserves signal integrity from high-impedance sources like piezoelectric sensors or pH electrodes. |
| Input Voltage Noise | 19 nV/√Hz at f = 1 kHz - 4× lower than prior micropower CMOS op-amps, critical for low-level transducer amplification. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs or low-voltage logic interfaces without level-shifting circuitry. |
| Common-Mode Input Range | Includes negative rail (VDD−) - simplifies single-supply design with ground-referenced sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2254QPWRQ1 | Same architecture but 1500 µV max VIO (vs. 850 µV); TSSOP-14 package (3.0 mm × 4.4 mm). | Lower precision requirement; space-constrained PCBs where SOIC-14 footprint is unavailable. | Select when cost sensitivity outweighs offset-critical performance and board area permits fine-pitch assembly. |
| LMV324QDRQ1 | Bipolar input; higher supply current (130 µA/ch); 3 mV max VIO; wider GBW (1 MHz); not rail-to-rail output. | Higher-speed signal paths (>10 kHz); less sensitive to input bias current; tolerant of larger offset. | Choose for faster settling or higher drive capability where rail-to-rail output is not mandatory and power budget allows. |
Compared with TLV2254QPWRQ1, TLV2254AQDRG4Q1 offers tighter offset spec and SOIC compatibility; versus LMV324QDRQ1, it provides superior DC precision, lower power, and rail-to-rail output at the expense of bandwidth - making it optimal for battery-sensitive, low-frequency automotive sensing.

FAQ
What is the maximum operating temperature range for TLV2254AQDRG4Q1?
The TLV2254AQDRG4Q1 is qualified per AEC-Q100 Grade 1 and operates reliably from −40°C to +125°C ambient temperature. This range covers under-hood and cabin-mounted automotive applications, including engine control, transmission, and body electronics modules where thermal extremes are common. All electrical specifications in the datasheet are guaranteed across this full range.
Does TLV2254AQDRG4Q1 support single-supply operation?
Yes, TLV2254AQDRG4Q1 is fully specified for single-supply operation from 2.7 V to 16 V. Its common-mode input voltage range extends to the negative rail (VDD−), and its rail-to-rail output swing allows full utilization of the supply range - enabling direct interface with 3.3 V or 5 V microcontrollers and ADCs without dual supplies or level shifters.
What is the typical supply current consumption of TLV2254AQDRG4Q1?
The TLV2254AQDRG4Q1 consumes 34 µA per channel typical (136 µA total for all four amplifiers) at 25°C with no load. At full temperature range (−40°C to +125°C), maximum supply current is 300 µA for all four channels. This micropower performance makes it ideal for always-on vehicle subsystems such as battery monitoring and occupancy sensing.
Is TLV2254AQDRG4Q1 pin-compatible with earlier TLV2324 variants?
Yes, TLV2254AQDRG4Q1 uses the same SOIC-14 pinout as TLV2324 and TLV2324-Q1. However, while pinout is identical, TLV2254AQDRG4Q1 offers improved rail-to-rail output swing, lower noise (19 nV/√Hz vs. ~30 nV/√Hz), lower input bias current (1 pA vs. ~100 pA), and tighter input offset voltage (850 µV max vs. 3 mV max), making it a functional upgrade without PCB redesign.
What packaging and marking information applies to TLV2254AQDRG4Q1?
TLV2254AQDRG4Q1 is supplied in a 14-pin SOIC (D) package with tape-and-reel packaging. Top-side marking is "TLV2254AQ1", consistent with TI's automotive Q1 ordering convention. The "G4" suffix indicates green (lead-free) packaging compliant with RoHS and ELV directives, and "Q1" denotes AEC-Q100 qualification.
