Product details

Overview

TLV2254QDRQ1 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 battery-powered sensor signal conditioning and ADC interface circuits where low power and wide common-mode range are critical.

For engineers reviewing the TLV2254QDRQ1 datasheet, TLV2254QDRQ1 pinout, TLV2254QDRQ1 application, or TLV2254QDRQ1 equivalent, key selection criteria include its rail-to-rail output swing, 34 µA per channel supply current, automotive temperature qualification, CMOS input stage enabling high-impedance source interfacing, and compatibility with single-supply 3 V/5 V systems.

Technical Context

The TLV2254QDRQ1 implements a CMOS-input, rail-to-rail output amplifier architecture optimized for low-voltage, low-power operation. Its input stage supports common-mode voltage down to the negative rail (VDD−), and its output swings within 10 mV of both supply rails under light load - enabling full dynamic range utilization in single-supply data acquisition systems.

It features fully specified performance across 3 V and 5 V supplies, with guaranteed operation from −40°C to +125°C. The device exhibits 65–75 dB common-mode rejection ratio (CMRR) and 80–95 dB supply voltage rejection ratio (SVRR), making it suitable for noisy automotive environments where precision analog front-ends must maintain accuracy despite supply ripple and ground shifts.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad micropower rail-to-rail op-amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV2254AQPWRQ1	Same architecture and pinout, but 850 µV max VIO (vs. 1500 µV for TLV2254QDRQ1) and TSSOP-14 package.	Preferred where tighter offset spec is required for precision DC measurements; TSSOP enables higher PCB density.	Select TLV2254AQPWRQ1 when offset-critical applications (e.g., strain gauge bridges) demand guaranteed ≤850 µV VIO at 25°C.
LMV324QDRQ1	Wider supply range (2.7–5.5 V), higher GBW (1 MHz), but higher noise (39 nV/√Hz) and no guaranteed rail-to-rail output below 100 µA load.	Suitable for higher-speed AC-coupled signal paths (e.g., audio preamp), but less optimal for low-noise DC sensor conditioning.	Choose LMV324QDRQ1 only when bandwidth >100 kHz is required and rail-to-rail output under heavy load is not mandatory.

Compared with TLV2254AQPWRQ1, TLV2254QDRQ1 trades guaranteed low offset for SOIC packaging and cost advantage; compared with LMV324QDRQ1, it prioritizes ultra-low noise and true rail-to-rail output over speed - making TLV2254QDRQ1 optimal for precision, low-power, automotive-grade DC signal chains.

FAQ

What is the maximum operating temperature range for TLV2254QDRQ1?

The TLV2254QDRQ1 is qualified for automotive Grade 1 operation, with a guaranteed operating free-air temperature range of −40°C to +125°C. All electrical specifications in the datasheet are validated across this full range, and the device undergoes HTOL, temperature cycling, and board-level reliability testing per AEC-Q100 requirements. This makes TLV2254QDRQ1 suitable for under-hood and cabin applications where ambient temperatures exceed 105°C.

Does TLV2254QDRQ1 support true rail-to-rail output swing under load?

Yes, TLV2254QDRQ1 delivers rail-to-rail output swing with ≤10 mV headroom to both supply rails at loads up to 100 µA. At 3 V supply and 25°C, VOH ≥2.98 V and VOL ≤10 mV for IOH = −20 µA and IOL = 50 µA respectively. This performance is maintained across the full −40°C to +125°C range, ensuring consistent ADC interface fidelity without external level-shifting circuitry in TLV2254QDRQ1-based designs.

How does the input offset voltage specification differ between TLV2254QDRQ1 and TLV2254AQDRQ1?

TLV2254QDRQ1 has a maximum input offset voltage (VIO) of 1500 µV at 25°C, while TLV2254AQDRQ1 is the "A" grade variant with tighter 850 µV max VIO at 25°C. Both share identical pinout, package, and temperature rating (−40°C to +125°C), but the "A" suffix denotes enhanced initial offset trimming. For applications requiring <0.017% gain error in unity-gain buffers at room temperature, TLV2254AQDRQ1 is preferred; TLV2254QDRQ1 offers cost and availability advantages where 1500 µV VIO is acceptable.

Can TLV2254QDRQ1 operate from a single 3.3 V supply in sensor interface applications?

Yes, TLV2254QDRQ1 is fully characterized and guaranteed for single-supply operation from 2.7 V to 16 V. At 3.3 V, it maintains rail-to-rail output swing, 1 pA input bias current, and 19 nV/√Hz noise - making it ideal for interfacing with 3.3 V microcontrollers and SAR ADCs. Its common-mode input range includes the negative rail (VDD−), allowing direct connection of ground-referenced sensors without level-shifting components in TLV2254QDRQ1 circuits.

What is the total supply current consumption of TLV2254QDRQ1 when all four amplifiers are active?

TLV2254QDRQ1 consumes 34 µA per channel typical, resulting in 136 µA total typical supply current for all four amplifiers at 25°C and 3 V supply. The datasheet specifies 250 µA maximum total IDD across −40°C to +125°C, ensuring predictable power budgeting in battery-powered TLV2254QDRQ1 systems. This ultra-low quiescent current enables multi-year operation on primary lithium cells in always-on monitoring applications.
