Product details
Overview
TLC2252AQDRQ1 from Texas Instruments is a dual, rail-to-rail output, automotive-qualified operational amplifier featuring 850 µV max input offset voltage at 25°C, 35 µA per channel supply current, and 19 nV/√Hz input voltage noise at 1 kHz. It operates from ±2.2 V to ±8 V supplies, supports single- or split-supply configurations, and delivers full-rail output swing - making it ideal for precision signal conditioning in battery-powered automotive sensor interfaces and ADC front-ends.
For engineers reviewing the TLC2252AQDRQ1 datasheet, TLC2252AQDRQ1 pinout, TLC2252AQDRQ1 application, or TLC2252AQDRQ1 equivalent, this device is selected for low-power, high-input-impedance analog signal chains requiring AEC-Q100 Grade 1 qualification, rail-to-rail output capability, and micropower operation below 125 µA total quiescent current.
Technical Context
The TLC2252AQDRQ1 uses Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ) and rail-to-rail output swing while maintaining stable unity-gain operation with 63° phase margin. Its input stage includes common-mode voltage range extending to the negative rail, enabling true single-supply operation down to 0 V reference.
It features fully characterized performance across −40°C to +125°C, with guaranteed 850 µV max input offset voltage and 0.5 µV/°C temperature coefficient - critical for automotive cabin temperature sensing, battery monitoring, and engine control loop amplification where drift must remain bounded over wide thermal excursions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports both split-supply industrial designs and single-supply 5 V systems with rail-compatible headroom. |
| Input Offset Voltage (max) | 850 µV at 25°C - enables accurate DC-coupled amplification of mV-level sensor outputs without trimming. |
| Supply Current (per channel) | 35 µA typ - allows dual-channel operation under 70 µA total, suitable for always-on automotive subsystems. |
| Input Voltage Noise | 19 nV/√Hz at 1 kHz - 4× lower than legacy micropower CMOS op-amps, improving SNR in piezoelectric transducer interfaces. |
| Common-Mode Input Range | Extends to VDD− - permits direct connection to ground-referenced sensors in single-supply configurations. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs with 0–5 V or ±2.5 V input ranges, minimizing signal loss. |
| Gain-Bandwidth Product | 0.2 MHz - sufficient for anti-aliasing filters, sensor buffering, and slow-control loops in automotive ECUs. |
Pinout & Package
Package: SOIC-8 (D package), 3.9 mm × 4.9 mm, surface-mount, RoHS-compliant, qualified per AEC-Q100 Grade 1 (−40°C to +125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - rail-to-rail capable, drives loads up to ±50 mA short-circuit current. |
| 2 | IN1− | Inverting input - high-impedance (10¹² Ω), accepts signals down to VDD−. |
| 3 | IN1+ | Non-inverting input - same impedance and common-mode range as IN1−. |
| 4 | GND / VDD− | Negative supply or ground reference - serves as return path for both amplifiers. |
| 5 | IN2+ | Non-inverting input of amplifier 2 - electrically isolated but shares supply rails with AMP1. |
| 6 | IN2− | Inverting input of amplifier 2 - matched AC/DC characteristics to IN1−. |
| 7 | OUT2 | Amplifier 2 output - independent rail-to-rail output, no crosstalk above 70 dB CMRR. |
| 8 | VDD+ | Positive supply - accepts up to +8 V; supports single-supply (5 V) or split-supply (±5 V) operation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers full-swing output within 10 mV of either rail at light loads, maximizing ADC utilization in 5 V systems. |
| Automotive qualification | AEC-Q100 Grade 1 certified - validated for continuous operation from −40°C to +125°C ambient, including thermal cycling and ESD robustness (2000 V HBM). |
| Ultra-low input bias current | 1 pA typical - preserves signal integrity when amplifying high-impedance sources like thermistors or pH electrodes. |
| Low-noise micropower design | 19 nV/√Hz noise at 1 kHz with only 35 µA per channel - achieves best-in-class noise/power ratio for battery-constrained modules. |
| Single- and split-supply compatible | Operates from 4.4 V to 16 V total supply or ±2.2 V to ±8 V - eliminates need for separate bias networks in mixed-voltage automotive domains. |

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 |
|---|---|---|---|
| TLV2432QDRQ1 | Higher output drive (60 mA vs 50 mA), wider input voltage range (to VDD+ − 0.1 V), but higher quiescent current (125 µA/ch vs 35 µA/ch). | Better suited for driving heavier capacitive loads or higher-speed settling, but less optimal for ultra-low-power always-on nodes. | Select TLV2432QDRQ1 when output current >50 mA or faster slew rate (0.5 V/µs) is required; retain TLC2252AQDRQ1 for sub-100 µA power budgets. |
| LM7332QMA/NOPB | Higher GBW (21 MHz), lower noise (11 nV/√Hz), but consumes 1.1 mA/ch and lacks AEC-Q100 Grade 1 certification. | Targeted at high-speed automotive infotainment or ADAS signal chains, not low-power body electronics. | Choose LM7332QMA/NOPB only for bandwidth-critical applications; TLC2252AQDRQ1 remains preferred for cost-sensitive, thermally constrained, or safety-qualified low-speed sensing. |
Compared with TLV2432QDRQ1 and LM7332QMA/NOPB, the TLC2252AQDRQ1 uniquely balances AEC-Q100 Grade 1 qualification, rail-to-rail output, sub-100 µA total supply current, and 850 µV precision - making it the optimal choice for battery-conscious automotive sensor signal conditioning where reliability and power efficiency are co-prioritized.

FAQ
What is the maximum operating temperature range for the TLC2252AQDRQ1?
The TLC2252AQDRQ1 is qualified for operation from −40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This rating is verified across all electrical parameters in the datasheet, including input offset voltage, CMRR, and supply current, ensuring consistent performance in under-hood and cabin-mounted automotive applications.
Does the TLC2252AQDRQ1 support single-supply operation?
Yes, the TLC2252AQDRQ1 fully supports single-supply operation - its common-mode input voltage range extends to the negative rail (VDD−), and its rail-to-rail output swings within 10 mV of both supply rails. When powered from 5 V (VDD+ = 5 V, VDD− = GND), it accepts inputs from 0 V and delivers outputs from near 0 V to near 5 V, simplifying interface to unipolar ADCs.
What is the input offset voltage specification for the TLC2252AQDRQ1?
The TLC2252AQDRQ1 has a maximum input offset voltage of 850 µV at TA = 25°C and 1000 µV across the full −40°C to +125°C operating range. This tighter VIO spec (vs. 1550 µV for the standard TLC2252QDRQ1) makes it suitable for precision DC amplification in automotive temperature, pressure, and current sensing applications.
Is the TLC2252AQDRQ1 pin-compatible with older TI op-amps like the TLC27L2?
No, the TLC2252AQDRQ1 is not pin-compatible with the TLC27L2. While both are dual SOIC-8 op-amps, the TLC2252AQDRQ1 uses a different pinout: pins 1–4 are OUT1, IN1−, IN1+, GND; pins 5–8 are IN2+, IN2−, OUT2, VDD+. The TLC27L2 uses OUT1, IN1−, IN1+, VDD+, IN2+, IN2−, OUT2, GND - requiring PCB layout revision for drop-in replacement.
What packaging and marking information applies to the TLC2252AQDRQ1?
The TLC2252AQDRQ1 is supplied in an SOIC-8 (D) package with tape-and-reel packaging. Top-side marking is "2252AQ", confirming the A-grade (850 µV VIO) and Q1 (automotive) variant. The "Q1" suffix denotes AEC-Q100 qualification, and "DR" indicates SOIC-8 with embossed carrier tape per TI's ordering nomenclature.
