Product details
Overview
TLV2472QDRG4Q1 from Texas Instruments is a dual-channel, automotive-qualified CMOS rail-to-rail input/output operational amplifier optimized for low-voltage sensor interface and data acquisition. It delivers 2.8 MHz gain-bandwidth, 600 µA/channel supply current, ±10 mA output drive at 180 mV from rails, 250 µV typical input offset voltage, and operates from 2.7 V to 6 V across −40°C to 125°C.
For engineers reviewing the TLV2472QDRG4Q1 datasheet, TLV2472QDRG4Q1 pinout, TLV2472QDRG4Q1 application, or TLV2472QDRG4Q1 equivalent, key selection considerations include rail-to-rail I/O swing in 3 V systems, micropower performance with usable AC bandwidth, high output current capability for driving capacitive loads, and AEC-Q100 Grade 1 qualification for automotive signal conditioning.
Technical Context
The TLV2472QDRG4Q1 implements a CMOS input stage with 2.5 pA typical input bias current and rail-to-rail differential input voltage range (0 V to VDD), enabling full-swing operation in single-supply configurations. Its output stage supports true rail-to-rail sourcing and sinking up to ±10 mA at 180 mV from supply rails, and ±35 mA at 500 mV from rails - resolving classic micropower op-amp output drive limitations.
Internally compensated for unity-gain stability, it achieves 1.5 V/µs typical slew rate and 61°–68° phase margin (depending on supply and load), with specified performance across the full automotive temperature range (−40°C to 125°C) at both 3 V and 5 V supplies. Input common-mode range extends to both supply rails, and output swing remains within 180 mV of each rail under 10-mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - enables direct use in 3.3 V and 5 V automotive microcontroller I/O domains without level-shifting. |
| Gain-Bandwidth Product | 2.8 MHz - supports stable closed-loop operation up to ~200 kHz in unity-gain buffer or low-noise instrumentation amplifier configurations. |
| Input Offset Voltage (typ) | 250 µV - ensures <1 LSB error in 12-bit ADC front-ends with gain ≤20, critical for precision sensor signal conditioning. |
| Supply Current per Channel | 600 µA - allows dual-channel operation at <1.2 mA total, suitable for battery-powered automotive subsystems with tight power budgets. |
| Output Drive Capability | ±10 mA at 180 mV from rail - drives 10 kΩ loads fully to rails while maintaining linearity, ideal for driving SAR ADC reference buffers or analog multiplexers. |
| Input Bias Current (typ) | 2.5 pA - minimizes voltage error across high-impedance sources (e.g., thermistors, pH electrodes, piezoelectric sensors) without external guarding. |
| Common-Mode Rejection Ratio | 84 dB (min at 5 V) - rejects engine noise and alternator ripple in vehicle-mounted sensor nodes operating near noisy power domains. |
Pinout & Package
SOP-8 (D package), surface-mount, thermally enhanced plastic small-outline package with exposed thermal pad (PowerPAD™). Pin 1 marked by beveled corner or dot; device qualified per AEC-Q100 Grade 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | Delivers rail-to-rail buffered or amplified signal; requires local 0.1 µF ceramic decoupling to GND for stability. |
| 1IN− | Channel 1 inverting input | High-impedance node (10¹² Ω); sensitive to PCB trace length and stray capacitance - keep routing short and away from noisy signals. |
| 1IN+ | Channel 1 noninverting input | Accepts rail-to-rail common-mode input (0 V to VDD); used for unity-gain buffers or active filters with DC-coupled inputs. |
| GND | Analog ground reference | Primary return path for both channels; must connect directly to low-inductance ground plane, not shared with digital or power grounds. |
| VDD | Positive supply | Accepts 2.7–6 V; requires 6.8 µF tantalum + 0.1 µF ceramic decoupling placed within 0.1 inch of pin. |
| 2OUT | Channel 2 output | Independent rail-to-rail output; can drive separate signal chain (e.g., second sensor channel or diagnostic monitor). |
| 2IN− | Channel 2 inverting input | Electrically isolated from Channel 1; supports dual independent amplification paths on single die. |
| 2IN+ | Channel 2 noninverting input | Enables simultaneous processing of two analog signals (e.g., differential pair + reference, or dual-axis sensor outputs). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3 V systems - e.g., 0–3.3 V ADC input coverage without negative supply or level-shifting circuitry. |

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 |
|---|---|---|---|
| TLV2472AQDRQ1 | Lower input offset voltage (250 µV max vs 2200 µV max over temp), tighter initial spec but same package and pinout. | Better suited for high-precision calibration-critical paths where offset drift matters more than cost. | Select TLV2472AQDRQ1 when initial offset <1600 µV is required at 25°C; otherwise TLV2472QDRG4Q1 offers optimal cost/performance balance for general automotive signal chains. |
| LMV722QDRQ1 | Higher GBW (10 MHz), lower supply current (420 µA), but only rail-to-rail output (not input); 1.2 mV max VIO over temp. | Preferred for higher-frequency filtering or faster settling where input common-mode range beyond rails is not needed. | Choose LMV722QDRQ1 when bandwidth >5 MHz is required and input swing beyond 0–VDD is unnecessary; TLV2472QDRG4Q1 remains superior for true rail-to-rail input in low-voltage sensor front-ends. |
Compared with TLV2472AQDRQ1 and LMV722QDRQ1, TLV2472QDRG4Q1 uniquely balances rail-to-rail input/output, 2.8 MHz bandwidth, and AEC-Q100 qualification in SOP-8 - making it the most broadly applicable dual op-amp for cost-sensitive, safety-aware automotive analog signal paths where full input voltage range and moderate speed are essential.

FAQ
What is the maximum operating temperature range for TLV2472QDRG4Q1?
The TLV2472QDRG4Q1 is qualified for automotive applications and operates reliably from −40°C to +125°C ambient temperature. This Grade 1 AEC-Q100 rating is verified across all electrical parameters in the datasheet, including input offset voltage, gain-bandwidth, and output drive capability - ensuring consistent performance in under-hood and powertrain environments where thermal stress is severe.
Does TLV2472QDRG4Q1 support true rail-to-rail input operation?
Yes, TLV2472QDRG4Q1 supports true rail-to-rail input operation: its common-mode input voltage range extends from 0 V to VDD, allowing signals at either supply rail to be accurately amplified. This is confirmed in the datasheet's "Recommended Operating Conditions" table and validated across temperature - enabling direct interfacing with resistive sensors, DAC outputs, and other circuits that swing to ground or supply without external level-shifting components.
What is the output drive capability of TLV2472QDRG4Q1 at 3.3 V supply?
At VDD = 3.3 V, TLV2472QDRG4Q1 delivers ±10 mA output current while maintaining output voltage within 180 mV of each rail, and ±35 mA while staying within 500 mV of each rail. These values are measured per channel and confirmed in the Electrical Characteristics tables for 3 V operation - making it capable of driving 330 Ω loads to full rail compliance or heavier capacitive loads such as ADC input networks and analog switches.
Is TLV2472QDRG4Q1 pin-compatible with other devices in the TLV247x family?
Yes, TLV2472QDRG4Q1 in the SOP-8 (D) package shares identical pinout with TLV2472, TLV2472A, and TLV2472QDRQ1 - all follow the standard dual-op-amp D-package configuration: 1OUT, 1IN−, 1IN+, GND, VDD, 2OUT, 2IN−, 2IN+. This allows direct substitution within the same footprint when upgrading or qualifying alternate variants, provided the application tolerates differences in offset voltage or temperature drift specifications.
What decoupling is recommended for stable operation of TLV2472QDRG4Q1?
Texas Instruments specifies a 6.8 µF tantalum capacitor in parallel with a 0.1 µF ceramic capacitor on the VDD pin, placed within 0.1 inch of the device. The 0.1 µF ceramic must be mounted directly at the VDD–GND pins to suppress high-frequency noise and prevent oscillation. For dual-channel use, separate 0.1 µF ceramics per channel are not required - one shared 0.1 µF ceramic at VDD suffices if layout minimizes trace inductance.
