Product details
Overview
TLV2254AQDREP from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-voltage, micropower operation in extended-temperature industrial and automotive applications. It delivers 850 µV max input offset voltage at 25°C, 19 nV/√Hz input voltage noise at 1 kHz, 34 µA per channel supply current, and full rail-to-rail output swing from 2.7 V to 16 V supplies - enabling high-precision signal conditioning in battery-powered sensor interfaces and ADC drivers.
For engineers reviewing the TLV2254AQDREP datasheet, TLV2254AQDREP pinout, TLV2254AQDREP application, or TLV2254AQDREP equivalent, this page provides verified technical context, package mapping, real-world use cases, and validated alternative options for designs requiring −40°C to 125°C operation, ultra-low power, and precision DC performance with rail-to-rail output capability.
Technical Context
The TLV2254AQDREP implements a CMOS-input, rail-to-rail output op-amp architecture with fully differential input stage and push-pull output stage. Its input bias current of 1 pA typ enables high-impedance source interfacing (e.g., piezoelectric transducers), while its 10¹² Ω common-mode and differential input resistance ensures minimal loading on sensitive nodes.
It is characterized across 3 V and 5 V supplies and supports single-supply operation down to 2.7 V. The device features enhanced ESD protection (100 V HBM), controlled baseline manufacturing, and qualification per JEDEC standards for extended temperature reliability - including HAST, temperature cycling, and intermetallic life testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports direct integration into 3.3 V, 5 V, and 12 V systems without level-shifting. |
| Input Offset Voltage (max) | 850 µV at TA = 25°C - enables accurate DC-coupled amplification in precision sensor front-ends. |
| Supply Current (per channel) | 34 µA typ - allows four-channel operation at <136 µA total, ideal for always-on battery monitoring. |
| Input Voltage Noise | 19 nV/√Hz at f = 1 kHz - 4× lower than prior micropower CMOS op-amps, critical for low-level signal integrity. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs (e.g., 0–3.3 V input range) without headroom loss. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive and industrial control environments. |
| Input Bias Current | 1 pA typ - preserves signal fidelity when amplifying high-Z sources like pH electrodes or photodiodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2254QDREP | 1500 µV max input offset voltage (vs. 850 µV); otherwise identical specs and pinout. | Suitable where DC accuracy is secondary to cost in non-precision industrial controls. | Select TLV2254QDREP only if system-level calibration compensates for higher offset drift. |
| OPA2333PWR | Zero-drift architecture (0.02 µV/°C drift), 17 nV/√Hz noise, but 55 µA/channel supply current and 1.8–5.5 V supply range. | Better for ultra-stable DC gain stages; less suitable for 12 V systems or ultra-low-power designs. | Choose OPA2333PWR when offset drift dominates error budget, not quiescent current. |
Compared with TLV2254QDREP, TLV2254AQDREP offers tighter DC accuracy for calibrated sensor systems; compared with OPA2333PWR, it trades zero-drift performance for lower power and wider supply range - making it optimal for cost-sensitive, battery-constrained, wide-voltage industrial sensing.

FAQ
What is the maximum supply voltage rating for TLV2254AQDREP?
The absolute maximum supply voltage for TLV2254AQDREP is 16 V, as specified in the Absolute Maximum Ratings table of the SGLS217B datasheet. Operation beyond this voltage risks permanent damage. Recommended operating range is 2.7 V to 8 V for optimal performance and reliability, though 12 V and 15 V operation is permissible within thermal limits.
Does TLV2254AQDREP support true rail-to-rail input?
No, TLV2254AQDREP does not support rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD−) but only to VDD+ −1.3 V at 3 V supply (or VDD+ −1.3 V at 5 V supply). This limitation is explicitly defined in the Recommended Operating Conditions table and confirmed across electrical characteristics sections for both 3 V and 5 V operation.
Is TLV2254AQDREP pin-compatible with TLV2254QDREP?
Yes, TLV2254AQDREP and TLV2254QDREP share identical SOIC-14 (D) package footprints and pin assignments. They differ only in input offset voltage specification (850 µV max vs. 1500 µV max) and qualification grade - both are drop-in replacements in PCB layout, requiring no hardware changes.
What is the typical supply current for TLV2254AQDREP at 5 V operation?
At VDD = 5 V and TA = 25°C, TLV2254AQDREP draws 140 µA total (35 µA per channel typ), as confirmed in the "TLV2254 electrical characteristics at VDD = 5 V" table on page 12 of SGLS217B. Full-range current is 300 µA maximum across −40°C to 125°C, ensuring predictable power budgeting in thermally demanding environments.
Can TLV2254AQDREP drive capacitive loads directly?
TLV2254AQDREP is stable with up to 100 pF capacitive load when configured as unity-gain follower, as verified in phase margin (63°) and gain margin (15 dB) measurements at RL = 50 kΩ and CL = 100 pF. Driving larger capacitive loads requires isolation resistor or compensation network per Figure 56–59 typical characteristics in the datasheet.
