Product details
Overview
TLV2252QD from Texas Instruments is a dual, rail-to-rail output, micropower CMOS operational amplifier designed for low-voltage, battery-powered systems. It delivers 19 nV/√Hz input voltage noise at 1 kHz, 34 µA per channel supply current, 850 µV max input offset voltage (at 25°C), and operates from 2.7 V to 8 V - enabling high-precision signal conditioning in automotive sensor interfaces and portable medical monitors.
For engineers reviewing the TLV2252QD datasheet, TLV2252QD pinout, TLV2252QD application, or TLV2252QD equivalent, key selection criteria include its rail-to-rail output swing, ultra-low input bias current (1 pA typ), wide common-mode input range extending to the negative rail, and Q-temp automotive qualification (−40°C to +125°C).
Technical Context
The TLV2252QD uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise. Its input stage supports common-mode voltages down to the negative rail, and its output can drive loads within 10 mV of both supply rails under light load conditions.
This device is fully characterized across −40°C to +125°C and optimized for single-supply operation at 3 V and 5 V. It features internal ESD protection, macromodel support for SPICE simulation, and is qualified to AEC-Q100 Grade 2 standards for automotive applications.
Key Specifications

|---|---|
| Supply Voltage Range | 2.7 V to 8 V - enables direct use with Li-ion, 3.3 V, and 5 V rails without regulation. |
| Supply Current per Channel | 34 µA typ - allows multi-year battery life in always-on sensor nodes and wearable devices. |
| Input Offset Voltage | 850 µV max at 25°C - ensures <±1 mV DC error in precision transducer amplification stages. |
| Input Voltage Noise | 19 nV/√Hz at 1 kHz - supports low-noise amplification of piezoelectric and thermopile signals. |
| Input Bias Current | 1 pA typ - preserves signal integrity when interfacing with high-impedance sources (>1 GΩ). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2252ID | Same electrical specs but rated for −40°C to +125°C industrial temp range; non-automotive qualification. | Lacks AEC-Q100 Grade 2 validation; not approved for safety-critical automotive modules. | Choose TLV2252ID only for cost-sensitive industrial designs where automotive qualification is unnecessary. |
| OPA2333QDGKR | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2252QD's 0.5 µV/°C; higher 17 µA/channel current. | Better long-term DC stability in temperature-varying environments; less suitable for ultra-low-power wake-up circuits. | Select OPA2333QDGKR when offset drift dominates system error budget over 10+ year lifetime, accepting 50% higher current draw. |
Compared with TLV2252ID, TLV2252QD adds automotive qualification and identical performance; compared with OPA2333QDGKR, it trades zero-drift stability for 40% lower quiescent current and simpler biasing - making TLV2252QD optimal for battery longevity in automotive cabin and body electronics.

FAQ
What is the operating temperature range for TLV2252QD?
The TLV2252QD is qualified for −40°C to +125°C free-air operating temperature, meeting AEC-Q100 Grade 2 requirements for automotive under-hood and cabin applications. This range is explicitly confirmed in the "Recommended Operating Conditions" table of the SLOS185D datasheet and applies to all electrical specifications unless otherwise noted.
Does TLV2252QD support true rail-to-rail input?
No, TLV2252QD features rail-to-rail *output* swing but only a common-mode input voltage range that includes the negative rail (VDD−) and extends to VDD+ −1.3 V. At 3 V supply, this yields a usable input range of 0 V to 1.7 V - sufficient for ground-referenced sensors but not full rail-to-rail input capability.
What is the maximum capacitive load TLV2252QD can drive stably?
TLV2252QD is characterized for stable operation with up to 100 pF capacitive load when configured with unity-gain and RL = 50 kΩ, delivering 63° phase margin and 15 dB gain margin. Driving larger capacitive loads (e.g., >200 pF) requires isolation resistor or gain adjustment to maintain stability.
Is TLV2252QD pin-compatible with TLV2252ID or TLV2252AQD?
Yes - TLV2252QD, TLV2252ID, and TLV2252AQD share identical 8-pin SOIC (D) package and pinout. All three variants use the same die and layout; differences are limited to screening, qualification, and specified VIO grade (850 µV max for 'A' versions, 1500 µV max for non-'A').
Can TLV2252QD operate from a 2.5 V supply?
No - the absolute minimum supply voltage is 2.7 V per the "Recommended Operating Conditions" table. Operation below 2.7 V is not characterized and may result in degraded rail-to-rail output swing, increased offset voltage, or instability. For 2.5 V systems, consider TI's TLV9002 or similar 2.2 V–5.5 V rail-to-rail op-amps.
