Product details
Overview
TLV2472AQDRG4Q1 from Texas Instruments is a dual-channel, automotive-qualified 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, ±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 management front-end amplification.
For engineers reviewing the TLV2472AQDRG4Q1 datasheet, TLV2472AQDRG4Q1 pinout, TLV2472AQDRG4Q1 application, or TLV2472AQDRG4Q1 equivalent, key selection criteria include rail-to-rail I/O swing under 3-V operation, 2.8-MHz bandwidth with micropower consumption, automotive temperature qualification, output drive capability into 10-mA loads within 180 mV of rails, and input bias current below 50 pA.
Technical Context
The TLV2472AQDRG4Q1 implements a CMOS input stage with rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing, enabling full dynamic range utilization in single-supply systems. Its architecture supports stable operation with capacitive loads up to 1000 pF when using external nulling resistors (RNULL ≥ 20 Ω), as verified by phase margin ≥61° at 25°C with 1000-pF load.
It features a unity-gain-stable design with 1.5 V/µs typical slew rate, 90 dB minimum large-signal differential voltage amplification (AVD) at 25°C, and 68–90 dB supply voltage rejection ratio (SVR) over 2.7–6 V supply range-enabling robust performance in noisy automotive power domains.

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 |
|---|---|---|---|
| TLV2472QDRQ1 | Same die, non-A grade; 1600-µV max input offset vs. 1800-µV for TLV2472AQDRG4Q1; no AEC-Q100 qualification. | Not approved for automotive safety-critical modules; suitable for consumer-grade portable instruments. | Select TLV2472QDRQ1 only when AEC-Q100 compliance and <1800-µV offset guarantee are not required. |
| LM7332MA/NOPB | Higher 22-MHz GBW, 2.5-mA/channel supply current, ±80-mA output; not automotive-qualified. | Used where speed >2.8 MHz is mandatory (e.g., ultrasonic flow meters); unsuitable for battery-constrained automotive modules. | Choose LM7332MA/NOPB only when bandwidth and drive exceed TLV2472AQDRG4Q1 capabilities and automotive qualification is unnecessary. |
Compared with TLV2472QDRQ1, the TLV2472AQDRG4Q1 provides guaranteed lower offset and automotive qualification; compared with LM7332MA/NOPB, it trades bandwidth and drive for 75% lower supply current and AEC-Q100 compliance-making it optimal for cost- and power-sensitive automotive analog front ends.

FAQ
What is the maximum capacitive load the TLV2472AQDRG4Q1 can drive without oscillation?
The TLV2472AQDRG4Q1 maintains stability with up to 1000 pF capacitive load when a series nulling resistor (RNULL ≥ 20 Ω) is placed between the output pin and the load. Without RNULL, oscillation risk increases above 10 pF. Phase margin remains ≥61° at 25°C with 1000-pF load and RNULL = 20 Ω, as confirmed in the SGLS180B datasheet Figure 18.
Does the TLV2472AQDRG4Q1 support true rail-to-rail input common-mode range?
Yes, the TLV2472AQDRG4Q1 supports a common-mode input voltage range from 0 V to VDD, verified across −40°C to 125°C. This allows direct interfacing with sensors referenced to ground or VDD, such as resistive bridge outputs or DAC buffers. Input stage CMOS architecture enables this full-range operation without phase reversal or increased bias current.
What is the guaranteed input offset voltage specification for TLV2472AQDRG4Q1 over temperature?
The TLV2472AQDRG4Q1 guarantees a maximum input offset voltage of 1800 µV over the full −40°C to 125°C operating range, per the "TLV247xA" row in the Electrical Characteristics tables (page 4 and 6 of SGLS180B). At 25°C, the typical value is 250 µV, with a maximum of 1600 µV.
Is the thermal pad on the TLV2472AQDRG4Q1 D-package electrically connected to any internal node?
No, the thermal pad on the TLV2472AQDRG4Q1 SOP-8 (D) package is electrically isolated from all internal terminals, as explicitly stated in the "General PowerPAD™ Design Considerations" section (page 16, Note A). It must be soldered to a dedicated PCB copper pour for thermal dissipation but may remain floating or tied to GND solely for thermal conduction-not for electrical reference.
How does the TLV2472AQDRG4Q1 compare to standard TLV2472 variants in terms of ESD robustness?
The TLV2472AQDRG4Q1 meets or exceeds 2000 V HBM (MIL-STD-883, Method 3015) and 200 V machine model (C = 200 pF, R = 0) ESD ratings-identical to all TLV247x-Q1 automotive variants. This level of protection is validated for assembly and in-system handling in automotive manufacturing environments and eliminates need for external ESD clamps in most board-level implementations.
