Product details
Overview
TLC2252AQDRG4Q1 from Texas Instruments is a dual, rail-to-rail output, automotive-qualified operational amplifier featuring 850 µV max input offset voltage at 25°C, 19 nV/√Hz input noise at 1 kHz, and 35 µA per channel supply current. It operates from ±2.2 V to ±8 V supplies, supports common-mode input down to the negative rail, and delivers full rail-to-rail output swing-ideal for precision signal conditioning in battery-powered automotive sensor interfaces.
For engineers reviewing the TLC2252AQDRG4Q1 datasheet, TLC2252AQDRG4Q1 pinout, TLC2252AQDRG4Q1 application, or TLC2252AQDRG4Q1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (−40°C to 125°C), low-input-bias-current (1 pA typ) compatibility with high-impedance sources, and guaranteed rail-to-rail output performance across single- and split-supply configurations.
Technical Context
The TLC2252AQDRG4Q1 implements Advanced LinCMOS™ process technology to achieve micropower operation without sacrificing input impedance or noise performance. Its input stage uses complementary MOSFET pairs enabling rail-inclusive common-mode range and ultra-low input bias current (1 pA typ), while the output stage employs Class AB push-pull architecture to deliver true rail-to-rail swing under load.
This device is fully specified for both single-supply (e.g., 5 V) and split-supply (e.g., ±5 V) operation, with guaranteed performance over −40°C to 125°C. It exhibits 63° phase margin and 15 dB gain margin at unity gain with 50 kΩ load and 100 pF capacitance, ensuring stable operation in unity-gain follower and active filter configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports wide automotive battery variation and enables direct interface with 3.3 V or 5 V systems. |
| Input Offset Voltage (max) | 850 µV at 25°C - enables accurate DC-coupled amplification in precision sensor front-ends without trimming. |
| Supply Current per Channel | 35 µA typ - allows multi-channel operation in always-on vehicle subsystems with minimal power budget impact. |
| Input Noise Voltage | 19 nV/√Hz at 1 kHz - 4× lower than legacy micropower CMOS op-amps, critical for low-level transducer signal integrity. |
| Common-Mode Input Range | Includes negative rail (VDD−) - permits direct sensing of ground-referenced signals in single-supply automotive applications. |
| Output Swing | Rail-to-rail - maximizes dynamic range when driving SAR or delta-sigma ADCs with 0–VDD input ranges. |

Pinout & Package
Package: SOIC-8 (D package), 3.9 mm × 4.9 mm body, 1.27 mm pitch, RoHS-compliant, G4-grade moisture sensitivity level.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives external loads up to ±50 mA; rail-to-rail swing ensures full utilization of ADC reference range. |
| 2 | IN1− | Inverting input of Amp 1 - high-impedance (10¹² Ω) node compatible with piezoelectric sensors and resistive bridges. |
| 3 | IN1+ | Non-inverting input of Amp 1 - same impedance as IN1−; common-mode range includes VDD− for ground-sensing applications. |
| 4 | GND / VDD− | Negative supply or ground reference - shared return path for both amplifiers; must be low-impedance to maintain PSRR >80 dB. |
| 5 | IN2+ | Non-inverting input of Amp 2 - electrically isolated from Amp 1 inputs; supports independent dual-channel signal paths. |
| 6 | IN2− | Inverting input of Amp 2 - matched bias current (<60 pA max) minimizes offset drift in differential configurations. |
| 7 | OUT2 | Amplifier 2 output - identical AC/DC specs to OUT1; enables dual-sensor readout or signal buffering + filtering in one package. |
| 8 | VDD+ | Positive supply - accepts 4.4 V to 16 V (single) or ±2.2 V to ±8 V (split); internal regulation ensures stable bias over supply transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432IDR | Higher drive capability (60 mA), wider supply range (2.7–6 V), but higher quiescent current (550 µA/ch) and no AEC-Q100 qualification. | Targeted at industrial/commercial portable equipment-not automotive-qualified; unsuitable for under-hood use. | Select TLV2432IDR only for non-automotive designs requiring higher output current and faster slew rate (1.5 V/µs). |
| LMV722QDRQ1 | Lower input offset (350 µV max), higher GBW (10 MHz), but higher supply current (120 µA/ch) and reduced rail-to-rail output swing (within 30 mV of rails). | Optimized for higher-speed signal chains (e.g., CAN bus analog front-ends); less suitable for ultra-low-power always-on sensing. | Choose LMV722QDRQ1 when system requires sub-microsecond response time and tighter DC accuracy, accepting higher power draw. |
Compared with TLV2432IDR and LMV722QDRQ1, the TLC2252AQDRG4Q1 uniquely balances AEC-Q100 Grade 1 qualification, 35 µA/channel micropower operation, and guaranteed rail-to-rail output-making it the optimal choice for cost-sensitive, thermally demanding automotive sensor nodes where longevity and low standby power are mandatory.

FAQ
What is the maximum operating temperature range for the TLC2252AQDRG4Q1?
The TLC2252AQDRG4Q1 is qualified per AEC-Q100 Grade 1 and operates reliably from −40°C to +125°C ambient temperature. This range is validated across all electrical parameters in the datasheet, including input offset voltage, supply current, and output swing, making it suitable for under-hood and transmission-control applications where thermal stress is extreme.
Does the TLC2252AQDRG4Q1 support single-supply operation?
Yes, the TLC2252AQDRG4Q1 supports true single-supply operation from 4.4 V to 16 V. Its common-mode input range extends to the negative rail (GND), and its output swings rail-to-rail-enabling direct interface with 3.3 V or 5 V microcontrollers and ADCs without level-shifting components. Full specifications are guaranteed at 5 V supply.
What is the input offset voltage specification for the TLC2252AQDRG4Q1?
The TLC2252AQDRG4Q1 has a maximum input offset voltage of 850 µV at 25°C and 1000 µV over the full −40°C to 125°C operating range. This tight VIO spec-combined with 0.5 µV/°C temperature coefficient-ensures stable DC accuracy in precision automotive sensor amplifiers without external trimming.
Is the TLC2252AQDRG4Q1 pin-compatible with earlier TLC27L2 or TS27L2 devices?
No, the TLC2252AQDRG4Q1 is not pin-compatible with TLC27L2 or TS27L2. While it serves as a functional upgrade-offering rail-to-rail output, lower noise (19 nV/√Hz vs. ~70 nV/√Hz), and lower VIO-the pinout differs: TLC2252AQDRG4Q1 uses standard dual-op-amp SOIC-8 layout (OUT1, IN1−, IN1+, GND, IN2+, IN2−, OUT2, VDD+), whereas TLC27L2 places VDD+ at Pin 8 and GND at Pin 4, requiring PCB redesign.
What packaging and marking information applies to the TLC2252AQDRG4Q1?
The TLC2252AQDRG4Q1 is supplied in an SOIC-8 (D) package with tape-and-reel packaging. Top-side marking is "2252AQ", consistent with TI's automotive-grade part identification scheme. The "G4" suffix denotes RoHS-compliant, green molding compound and qualifies the part for moisture sensitivity level 3 (MSL-3) per J-STD-020.
