Product details
Overview
TLV2252AQDREP from Texas Instruments is a dual-channel, rail-to-rail output, micropower operational amplifier optimized for low-voltage (2.7 V to 8 V), precision signal conditioning in extended-temperature industrial and automotive applications. It delivers 19 nV/√Hz input voltage noise at 1 kHz, 850 µV max input offset voltage at 25°C, and 34 µA per channel supply current - enabling high-fidelity sensor interfacing in battery-powered remote monitoring systems.
For engineers reviewing the TLV2252AQDREP datasheet, TLV2252AQDREP pinout, TLV2252AQDREP application, or TLV2252AQDREP equivalent, this page provides verified electrical specifications, SOIC-8 package terminal mapping, rail-to-rail output behavior under single-supply operation, and validated alternative options for precision analog front-end design.
Technical Context
The TLV2252AQDREP employs Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ) and rail-to-rail output swing - allowing full dynamic range utilization with 3-V or 5-V supplies. Its CMOS input stage supports common-mode input voltage down to the negative rail (VDD−), critical for single-supply transducer amplification.
It features internal compensation for unity-gain stability with 100-pF capacitive loads, 63° phase margin, and 15 dB gain margin. The device is fully characterized across −40°C to +125°C, qualified per JEDEC standards including HAST, temperature cycling, and electromigration testing for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - enables direct interface with Li-ion, 3.3-V, and 5-V logic rails without level-shifting. |
| Input Offset Voltage (max) | 850 µV at 25°C - ensures ≤0.017% error in 5-V full-scale instrumentation amplifier configurations. |
| Supply Current per Channel | 34 µA typ - supports >1-year battery life in 10-µA average-power IoT sensor nodes. |
| Input Voltage Noise | 19 nV/√Hz at 1 kHz - 4× lower than prior micropower CMOS op-amps, critical for piezoelectric and strain-gauge signal integrity. |
| Output Swing | Rail-to-rail - delivers >99% of supply voltage swing, maximizing ADC input range when driving 12-bit+ SAR converters. |
| Common-Mode Input Range | Includes VDD− - permits direct amplification of ground-referenced sensors (e.g., thermistors, RTDs) without biasing circuitry. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
TLV2252AQDREP is housed in an 8-pin SOIC (D) package with standard 1.27-mm pitch and 3.91-mm body width. Pin numbering follows TI's dual-amplifier top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Inverting amplifier output - drives external load or ADC input with rail-to-rail capability. |
| 2 | IN1− | Inverting input - accepts feedback network or differential signal path; high-impedance (10¹² Ω). |
| 3 | IN1+ | Non-inverting input - connects to sensor reference or high-Z source; supports common-mode down to VDD−. |
| 4 | VDD−/GND | Negative supply / ground reference - serves as return path for both channels and PCB reference plane. |
| 5 | IN2+ | Non-inverting input (Channel 2) - independent of Channel 1; enables dual-sensor or differential pair processing. |
| 6 | IN2− | Inverting input (Channel 2) - supports separate feedback or gain-setting resistors per channel. |
| 7 | OUT2 | Output (Channel 2) - electrically isolated from OUT1; shares same rail-to-rail drive strength. |
| 8 | VDD+ | Positive supply - powers both amplifiers; accepts 2.7–8 V with no external regulation required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers ≥99% of VDD swing at 1-mA load - eliminates need for dual supplies when interfacing with 3.3-V ADCs. |
| Ultra-low input bias current | 1 pA typical - prevents signal degradation in high-impedance pH, piezo, or photodiode circuits (>1 GΩ sources). |
| Low-noise performance | 19 nV/√Hz at 1 kHz - preserves SNR in sub-100-µV sensor outputs without requiring external filtering. |
| Extended temperature qualification | −40°C to +125°C with JEDEC HAST and temperature-cycle validation - meets AEC-Q100 stress requirements for automotive use. |
| Single-supply operation | Fully specified from 2.7 V - enables direct integration into energy-harvesting and coin-cell powered designs. |

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 |
|---|---|---|---|
| TLV2252QDREP | 1500 µV max input offset voltage (vs. 850 µV); otherwise identical specs and pinout. | Suitable for cost-sensitive industrial controls where <0.03% gain error is acceptable. | Select TLV2252QDREP only if VIO tolerance relaxation is permissible in final calibration budget. |
| OPA2333AIDR | Zero-drift architecture; 2 µV max VIO, 0.02 µV/°C drift, but 17 µA higher quiescent current (51 µA/ch). | Better for DC-critical applications like precision weight scales; less optimal for ultra-low-power battery use. | Choose OPA2333AIDR when long-term DC stability outweighs battery life; avoid if <35 µA/ch is mandatory. |
Compared with TLV2252QDREP, TLV2252AQDREP offers tighter VIO for improved absolute accuracy in uncalibrated systems; versus OPA2333AIDR, it trades zero-drift performance for 49% lower supply current - making it superior for energy-constrained edge nodes.

FAQ
What is the maximum supply voltage for TLV2252AQDREP?
The absolute maximum supply voltage for TLV2252AQDREP is 16 V, but its recommended operating range is 2.7 V to 8 V. Operating above 8 V does not improve performance and may increase power dissipation beyond thermal limits in the SOIC-8 package. For reliable long-term operation, maintain VDD within the 2.7–8 V window specified in the datasheet.
Does TLV2252AQDREP support true rail-to-rail input?
No, TLV2252AQDREP supports rail-to-rail *output* swing but only common-mode input voltage down to the negative rail (VDD−). Its input common-mode range extends from VDD− to (VDD+ − 1.3 V) at 3 V supply, meaning the positive input cannot reach VDD+. This is sufficient for ground-referenced sensors but requires external biasing for full-rail input signals.
Can TLV2252AQDREP drive a 10-kΩ load while maintaining rail-to-rail output?
Yes - TLV2252AQDREP guarantees rail-to-rail output swing into 10-kΩ loads at room temperature. At 25°C and VDD = 3 V, VOH ≥ 2.98 V and VOL ≤ 10 mV with IOH/IOL = ±20 µA. Even at 125°C, output swing remains ≥2.8 V high and ≤300 mV low into 1-kΩ loads, confirming robust drive capability for typical ADC input impedances.
Is TLV2252AQDREP qualified for automotive applications?
Yes - TLV2252AQDREP is an automotive-grade Q1 part, qualified per JEDEC standards including HAST, temperature cycling, and electromigration. It operates reliably from −40°C to +125°C and carries TI's Controlled Baseline and Enhanced DMS support, making it suitable for under-dash and cabin modules (e.g., climate control, occupancy detection) but not under-hood engine control.
How does TLV2252AQDREP compare to TLV2252AQPWREP?
TLV2252AQDREP and TLV2252AQPWREP share identical electrical specifications and temperature grading (−40°C to +125°C), differing only in package: SOIC-8 (D) vs. TSSOP-8 (PW). The SOIC version offers better thermal dissipation (725 mW at 25°C vs. 525 mW) and is preferred for higher ambient temperatures or higher-output-current applications, while TSSOP suits space-constrained PCBs.
