Product details
Overview
TLV2471QDBVRQ1 from Texas Instruments is an automotive-grade, single-channel CMOS rail-to-rail input/output operational amplifier optimized for low-voltage, low-power sensor signal conditioning. It delivers 2.8 MHz gain-bandwidth, 600 µA supply current per channel, ±35 mA output drive at 500 mV from rail, 250 µV typical input offset voltage, and operates from 2.7 V to 6 V across −40°C to 125°C. It is used in automotive cabin pressure sensors and battery monitoring front-ends.
For engineers reviewing the TLV2471QDBVRQ1 datasheet, TLV2471QDBVRQ1 pinout, TLV2471QDBVRQ1 application, or TLV2471QDBVRQ1 equivalent, key selection criteria include rail-to-rail I/O swing under 3-V operation, 2.5 pA input bias current for high-impedance source interfacing, thermal robustness in under-hood environments, and SOT-23-5 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2471QDBVRQ1 employs a CMOS input stage enabling ultra-low input bias current (2.5 pA) and rail-to-rail common-mode input range (0 V to VDD). Its output stage supports true rail-to-rail swing under 10-mA load (to within 180 mV of each rail) and high-current sourcing/sinking (±35 mA at 500 mV off rail), making it suitable for driving resistive loads directly without external buffers.
It features internal compensation for unity-gain stability, 1.5 V/µs slew rate, and phase margin ≥61° with 1 nF capacitive load. The device is fully specified across the automotive temperature range and qualified per AEC-Q100 Grade 1, with ESD protection exceeding 2000 V HBM and 200 V MM.
Key Specifications

| Input Bias Current | 2.5 pA (typ) - Minimizes voltage error when amplifying signals from high-impedance sources like piezoresistive sensors. |
| Output Drive Capability | ±35 mA at 500 mV from rail - Drives 100-Ω loads directly; eliminates need for external output transistors in actuator interfaces. |
| Input Offset Voltage | 250 µV (typ) - Limits DC error to <0.5% full-scale in 50-mV-range thermistor or strain gauge bridges. |
| Quiescent Current | 600 µA per channel - Enables always-on operation in low-power vehicle subsystems with <2 mW total dissipation at 3.3 V. |
| Operating Temperature | −40°C to 125°C - Qualified for engine bay, transmission control, and ADAS ECU locations per AEC-Q100 Grade 1. |
Pinout & Package
SOT-23-5 (DBV) package: 2.9 mm × 1.6 mm × 1.15 mm body, gull-wing leads, exposed pad not electrically connected. Thermal resistance θJA = 324.1°C/W enables 385 mW power rating at TA ≤ 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; capable of ±35 mA continuous drive at 500 mV from rail. |
| 2 (GND) | Analog ground reference | Single-point connection point for low-noise analog return; must be isolated from digital ground planes. |
| 3 (IN+) | Non-inverting input | CMOS input with 1012 Ω impedance; accepts common-mode voltages from 0 V to VDD. |
| 4 (VDD) | Positive supply | Accepts 2.7–6 V; requires local 0.1-µF ceramic + 6.8-µF tantalum decoupling per layout guidelines. |
| 5 (IN−) | Inverting input | Differential input node; matched to IN+ for <250 µV offset; sensitive to PCB trace length and parasitic capacitance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2471AQDBVRQ1 | Lower 1600 µV max input offset voltage (vs 2400 µV for TLV2471QDBVRQ1); same package, pinout, and specs otherwise. | Better suited for precision bridge amplification where <1 mV total offset is required. | Select TLV2471AQDBVRQ1 when offset-critical medical or industrial sensing dominates cost sensitivity. |
| LM7321QDRQ1 | Higher 21 MHz GBW and 15 V/µs slew rate; 1.3 mA supply current; same AEC-Q100 Grade 1 qualification. | Required for high-speed active filters or wideband sensor excitation circuits beyond 2.8 MHz. | Choose LM7321QDRQ1 only when bandwidth >5 MHz is mandatory and 2× higher quiescent current is acceptable. |
Compared with TLV2471AQDBVRQ1, the TLV2471QDBVRQ1 trades 1.4 mV higher max offset for broader availability and lower unit cost; versus LM7321QDRQ1, it provides 5.5× lower supply current at 33% of the bandwidth-ideal for always-on, battery-sensitive automotive subsystems.

FAQ
What is the maximum capacitive load the TLV2471QDBVRQ1 can drive without instability?
The TLV2471QDBVRQ1 maintains ≥61° phase margin with up to 1 nF capacitive load when configured as a unity-gain buffer with RL = 10 kΩ. For loads >10 pF, TI recommends adding a series null resistor (RNULL) of 20–100 Ω between the OUT pin and the capacitive load to preserve stability. This is documented in Figure 34 of the SGLS180B datasheet.
Does the TLV2471QDBVRQ1 support single-supply operation below 3 V?
Yes, the TLV2471QDBVRQ1 is fully specified down to 2.7 V supply voltage. At 2.7 V, it retains rail-to-rail input common-mode range (0 V to 2.7 V), 2.8 MHz gain-bandwidth, and 600 µA supply current. Input offset voltage remains ≤2400 µV across −40°C to 125°C, enabling reliable operation in low-voltage automotive subsystems such as body control modules.
Is the thermal pad on the TLV2471QDBVRQ1 DBV package electrically connected?
No, the exposed thermal pad on the TLV2471QDBVRQ1 SOT-23-5 (DBV) package is electrically isolated from all terminals. It serves solely for thermal conduction and must be soldered to a copper pour connected to PCB ground or a dedicated thermal plane to achieve the rated θJA of 324.1°C/W. This isolation is confirmed in TI's DBV package drawings and the SGLS180B datasheet Section 16.
How does the TLV2471QDBVRQ1 handle input overvoltage beyond the supply rails?
The TLV2471QDBVRQ1 specifies absolute maximum differential input voltage as ±VDD and common-mode input voltage range as 0 V to VDD. Inputs exceeding VDD or falling below GND risk latch-up or permanent damage. External clamping diodes or series resistors are required for inputs exposed to transients beyond these limits-such as in CAN bus or LIN physical layer interfaces-since the device lacks integrated overvoltage protection beyond ESD-rated pins.
Can the TLV2471QDBVRQ1 be used in a dual-supply configuration?
Yes, the TLV2471QDBVRQ1 supports split-supply operation with ±1.35 V to ±3 V (i.e., total supply 2.7 V to 6 V). In dual-supply mode, the common-mode input range extends from −1.35 V to +3 V (for ±1.35 V supplies), and output swings rail-to-rail symmetrically. This configuration is validated in the "Recommended Operating Conditions" table of SGLS180B and enables bipolar signal processing in automotive audio preamplifiers or active filter stages.
