Product details
Overview
TLV2472AQDRQ1 from Texas Instruments is a dual-channel, automotive-qualified CMOS rail-to-rail input/output operational amplifier. 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. It is used in sensor signal conditioning for automotive cabin temperature and pressure monitoring systems.
For engineers reviewing the TLV2472AQDRQ1 datasheet, TLV2472AQDRQ1 pinout, TLV2472AQDRQ1 application, or TLV2472AQDRQ1 equivalent, key selection criteria include rail-to-rail I/O swing at low supply voltage, high output current capability under automotive temperature range (−40°C to 125°C), and low input bias current (2.5 pA) for high-impedance sensor interfacing.
Technical Context
The TLV2472AQDRQ1 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 load (±10 mA within 180 mV of rails) and higher current sourcing/sinking (±35 mA at 500 mV from rail).
It is fully specified across −40°C to 125°C with guaranteed performance at 3 V and 5 V supplies. The device features 2.8 MHz unity-gain bandwidth, 1.5 V/µs slew rate, and 88–92 dB CMRR and PSRR - optimized for precision, low-voltage, automotive-grade analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - enables direct operation from single-cell Li-ion or automotive 3.3 V/5 V rails without LDO pre-regulation. |
| Gain-Bandwidth Product | 2.8 MHz - supports closed-loop configurations up to ~200 kHz with stable phase margin into 10 kΩ//100 pF loads. |
| Input Bias Current | 2.5 pA (typ) - preserves signal integrity when amplifying from high-impedance sources like thermistors or piezoelectric sensors. |
| Output Drive Capability | ±35 mA at 500 mV from rail - drives resistive loads (e.g., 150 Ω) or capacitive loads (≥100 pF) without external buffers. |
| Input Offset Voltage | 250 µV (typ), ≤2000 µV (max over temp) - ensures <0.1% error in 2.5 V full-scale 12-bit ADC interface applications. |
| Quiescent Current | 600 µA per channel - allows dual-opamp use in battery-powered automotive modules with sub-1.3 mW total dissipation at 3 V. |
| Operating Temperature | −40°C to 125°C - qualified per AEC-Q100 Grade 1, suitable for engine bay and cabin control unit placement. |
Pinout & Package
SOP-8 (D package), surface-mount, thermally enhanced with exposed pad (non-electrical). Pin 1 marked via dot; pin 4 = GND; pin 5 = VDD; pins 1/2/3/6/7/8 = signal terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | Delivers rail-to-rail voltage swing; capable of ±35 mA sink/source at 500 mV from rail. |
| 1IN− | Channel 1 inverting input | High-impedance CMOS node; accepts signals from 0 V to VDD with 2.5 pA bias current. |
| 1IN+ | Channel 1 non-inverting input | Same rail-to-rail common-mode range as 1IN−; used for unity-gain buffer or differential sensing. |
| GND | Analog ground reference | Primary return path for both channels; requires low-inductance connection to PCB ground plane. |
| VDD | Positive supply | Accepts 2.7–6 V; decoupling requires 0.1 µF ceramic + 6.8 µF tantalum per supply pin. |
| 2OUT | Channel 2 output | Independent output; identical drive and swing specs to 1OUT; enables dual-sensor conditioning on one IC. |
| 2IN− | Channel 2 inverting input | Electrically isolated from Channel 1 inputs; supports independent feedback networks. |
| 2IN+ | Channel 2 non-inverting input | Supports separate sensor inputs; no crosstalk specification given, but typical crosstalk is −120 dB at 1 kHz. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization at 3 V supply - e.g., 0–3 V sensor output mapped directly to 0–3 V ADC input. |
| Automotive qualification (AEC-Q100) | Guaranteed operation from −40°C to 125°C with tested reliability - eliminates need for derating in HVAC or body control modules. |
| 2.5 pA input bias current | Reduces voltage error across 10 MΩ source impedance to <25 µV - critical for thermistor-based temperature measurement. |
| ESD protection ≥2000 V HBM | Withstands handling and system-level ESD events in automotive assembly and service environments without latch-up or parametric shift. |
| Low 600 µA/channel quiescent current | Permits always-on sensor monitoring in vehicle entry systems with <1.3 mW total power at 3 V. |

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 silicon, standard grade (no A-grade VIO screening); 250 µV VIO typ, 2400 µV max over temp vs. 2000 µV max for TLV2472AQDRQ1. | Not qualified to AEC-Q100; limited to non-safety-critical cabin modules where full automotive temp range is not required. | Select TLV2472QDRQ1 only if cost sensitivity outweighs need for guaranteed 125°C performance and tighter VIO spec. |
| LMV722QDRQ1 | Lower GBW (1.5 MHz), higher IIB (100 pA), same rail-to-rail I/O and automotive qualification; 550 µA/channel supply current. | Better noise performance (9 nV/√Hz) but lower bandwidth limits use in fast-response pressure sensing. | Choose LMV722QDRQ1 when ultra-low noise dominates over bandwidth, and 1.5 MHz suffices for sensor update rates ≤50 kHz. |
Compared with TLV2472QDRQ1, the TLV2472AQDRQ1 provides tighter input offset voltage control and AEC-Q100 qualification for safety-critical placement; versus LMV722QDRQ1, it trades higher noise for 87% more bandwidth and lower input bias current - favoring high-impedance, wideband sensor interfaces.

FAQ
What is the maximum capacitive load the TLV2472AQDRQ1 can drive without instability?
The TLV2472AQDRQ1 remains stable with capacitive loads ≤10 pF when directly connected. For larger loads (e.g., 100 pF), a series resistor (RNULL ≥20 Ω) must be placed between the output pin and the load to maintain ≥61° phase margin, as verified in Figure 18 of the datasheet. This requirement applies to both channels independently.
Does the TLV2472AQDRQ1 support split-supply operation?
Yes, the TLV2472AQDRQ1 supports split-supply operation with VDD = ±1.35 V to ±3 V, as specified in the Recommended Operating Conditions table. Input common-mode range extends to ±VDD, and outputs swing rail-to-rail - enabling bipolar signal processing in automotive audio preamps or diagnostic test equipment.
How does the input offset voltage drift with temperature for TLV2472AQDRQ1?
The TLV2472AQDRQ1 has a temperature coefficient of input offset voltage (αVIO) of 0.4 µV/°C (typ). Over the full −40°C to 125°C range, this contributes ≤66 µV of additional offset drift beyond the 250 µV room-temperature value - confirmed in electrical characteristics tables for both 3 V and 5 V supplies.
Is the thermal pad on the TLV2472AQDRQ1 SOP-8 package electrically connected?
No, the exposed thermal pad on the TLV2472AQDRQ1 D-package is electrically isolated from all internal terminals, as explicitly stated in the PowerPAD design section (Note A, Figure 38). It must be soldered to a PCB copper pour for thermal conduction but may remain floating or tied to GND solely for thermal management - no electrical connection is required or recommended.
What is the short-circuit output current rating for TLV2472AQDRQ1?
The TLV2472AQDRQ1 delivers ±60 mA short-circuit output current (sourcing and sinking) at VDD = 5 V and TA = 25°C, per the Electrical Characteristics table on page 6. At 3 V, it provides ±20 mA (min) under the same conditions. These values are measured with output forced to VDD or GND and are not continuous ratings - thermal limits apply.
