Product details
Overview
TLV2472QDRQ1 from Texas Instruments is a dual-channel, automotive-grade CMOS rail-to-rail input/output operational amplifier optimized for low-voltage sensor signal conditioning. It delivers 2.8 MHz gain-bandwidth, 600 µA/channel supply current, 250 µV typical input offset voltage, and ±35 mA output drive at 500 mV from rail - enabling high-precision, low-power analog front-ends in battery-powered automotive ECUs.
For engineers reviewing the TLV2472QDRQ1 datasheet, TLV2472QDRQ1 pinout, TLV2472QDRQ1 application, or TLV2472QDRQ1 equivalent, key selection criteria include its −40°C to 125°C automotive qualification, rail-to-rail I/O swing at 2.7–6 V supply, 2.5 pA input bias current, and validated stability with capacitive loads up to 100 pF using RNULL compensation.
Technical Context
The TLV2472QDRQ1 employs a CMOS input stage with differential pair architecture delivering ultra-low input bias current (2.5 pA typ) and rail-to-rail common-mode input range (0 V to VDD). Its output stage uses complementary push-pull circuitry enabling true rail-to-rail output swing under 10 mA load and high-current sourcing/sinking (±35 mA at 500 mV from rail).
It features unity-gain stable compensation optimized for 2.8 MHz bandwidth across 2.7–6 V supply, with phase margin ≥61° into 1000 pF capacitive load and slew rate of 1.5 V/µs (VDD = 5 V). Input noise is 15 nV/√Hz at 1 kHz, supporting precision DC-coupled amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion, 3.3 V, and 5 V systems without level-shifting. |
| Gain-Bandwidth Product | 2.8 MHz - enables stable closed-loop gain ≥10 at 280 kHz for anti-aliasing filter interfaces. |
| Input Bias Current | 2.5 pA (typ) - minimizes voltage error in high-impedance sensor bridges (e.g., RTD, piezoresistive). |
| Output Drive | ±35 mA at 500 mV from rail - drives 100 Ω loads directly, eliminating external buffers in actuator drivers. |
| Input Offset Voltage | 250 µV (typ) - ensures ≤0.5% gain error in 12-bit ADC front-ends with 1 V full-scale reference. |
| Quiescent Current | 600 µA per channel - allows dual op-amp operation in <1.3 mW total power budget at 3 V. |
| Operating Temperature | −40°C to 125°C - qualified per AEC-Q100 Grade 1 for engine control, transmission, and ADAS modules. |
Pinout & Package
SOP-8 (D package), 3.9 mm × 4.9 mm body, 1.27 mm pitch, thermally enhanced with exposed pad (non-electrical). Pin 1 marked by notch or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | Drives external load; rail-to-rail swing (0.178 V to 4.82 V at 5 V, 10 mA sink/source). |
| 1IN− | Channel 1 inverting input | Differential node for feedback networks; 1012 Ω input resistance enables high-Z sensor interfacing. |
| 1IN+ | Channel 1 non-inverting input | Reference or signal input; common-mode range extends to both rails (0 V to VDD). |
| GND | Analog ground reference | Return path for all channels; requires low-inductance connection to PCB ground plane. |
| VDD | Positive supply | Single-supply input (2.7–6 V); decoupling requires 0.1 µF ceramic + 6.8 µF tantalum per supply pin. |
| 2OUT | Channel 2 output | Independent output; identical AC/DC specs to Channel 1, enabling dual-path signal processing. |
| 2IN− | Channel 2 inverting input | Isolated from Channel 1 inputs; crosstalk ≤−140 dB at 1 kHz supports simultaneous sampling. |
| 2IN+ | Channel 2 non-inverting input | Full rail-to-rail common-mode range; matched offset drift (0.4 µV/°C) enables ratiometric designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2472CDR | Commercial grade (0°C to 70°C), same electrical specs but no AEC-Q100 qualification or automotive temp range. | Not suitable for under-hood or safety-critical systems requiring −40°C to 125°C operation. | Select TLV2472QDRQ1 when automotive qualification, extended temperature, or enhanced ESD robustness is mandatory. |
| LMV722QDRQ1 | Lower GBW (1.5 MHz), higher supply current (1.25 mA/ch), but lower input offset (150 µV typ) and wider supply (2.7–5.5 V). | Better DC precision but insufficient bandwidth for fast transient sensing; higher power limits battery life in portable diagnostics tools. | Choose LMV722QDRQ1 only if sub-200 µV offset dominates over bandwidth and quiescent current requirements. |
Compared with TLV2472CDR and LMV722QDRQ1, the TLV2472QDRQ1 uniquely balances automotive qualification, 2.8 MHz bandwidth, and 600 µA/channel quiescent current - making it optimal for cost-sensitive, thermally demanding, and safety-relevant dual-op-amp functions in modern vehicle ECUs.

FAQ
What is the maximum capacitive load the TLV2472QDRQ1 can drive without oscillation?
The TLV2472QDRQ1 maintains ≥61° phase margin into 1000 pF capacitive load when configured as unity-gain follower with RL = 10 kΩ. For loads >10 pF, TI recommends adding a series RNULL resistor (20–100 Ω) between output and load to preserve stability - verified in Figure 18–19 of the SGLS180B datasheet. This enables direct driving of LCD panels or long PCB traces without external isolation components.
Does the TLV2472QDRQ1 support single-supply operation below 3 V?
Yes, the TLV2472QDRQ1 is fully specified down to 2.7 V supply voltage across −40°C to 125°C. 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/channel quiescent current - enabling compatibility with single-cell LiFePO4 (2.8–3.6 V) and emerging low-voltage automotive subsystems.
How does the input offset voltage drift affect precision over temperature in TLV2472QDRQ1?
The TLV2472QDRQ1 has a temperature coefficient of input offset voltage of 0.4 µV/°C (max). Over the full −40°C to 125°C range (165°C span), this contributes ≤66 µV additional offset drift beyond the 250 µV typical room-temperature value - resulting in <320 µV total offset across automotive operating conditions, sufficient for 12-bit accuracy in 1 V full-scale systems.
Can TLV2472QDRQ1 replace legacy TLV2372 in existing automotive designs?
Yes, the TLV2472QDRQ1 is pin-compatible with TLV2372 in SOP-8 (D) package and offers superior performance: 2.8 MHz GBW vs. 1 MHz, 600 µA vs. 20 µA supply current, and rail-to-rail I/O vs. limited input range. However, verify layout for improved PSRR (92 dB vs. 70 dB) and reduced noise - no PCB changes required due to identical footprint and pinout.
What thermal management is required for TLV2472QDRQ1 in continuous 35 mA output operation?
At 35 mA output into 500 mV dropout, power dissipation reaches ~35 mW per channel. The SOP-8 package has θJA = 176°C/W; with standard 2-layer PCB and 1 in² copper pour, junction temperature rise is <7°C above ambient. No heatsink needed - but TI recommends connecting the exposed thermal pad to internal ground plane via ≥5 vias (13 mil diameter) per Figure 39 for sustained high-current operation in 125°C environments.
