Product details
Overview
TLV2252QDREP from Texas Instruments is a dual, rail-to-rail output, micropower CMOS operational amplifier optimized for low-voltage (2.7 V to 8 V) single-supply operation across −40°C to 125°C. It delivers 34 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, 850 µV max input offset voltage at 25°C, and rail-to-rail output swing - enabling high-precision signal conditioning in battery-powered industrial sensors and remote analog front-ends.
For engineers reviewing the TLV2252QDREP datasheet, TLV2252QDREP pinout, TLV2252QDREP application, or TLV2252QDREP equivalent, key selection criteria include its extended temperature qualification, ultra-low input bias current (1 pA typ), wide common-mode input range (includes negative rail), and guaranteed performance at 3 V - critical for interfacing with low-power ADCs and high-impedance transducers.
Technical Context
The TLV2252QDREP employs Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise. Its input stage operates with common-mode voltage extending to the negative rail, supporting true single-supply sensor interface topologies without level-shifting circuitry.
It is fully characterized over −40°C to 125°C with enhanced DMS support and JEDEC-qualified reliability testing including HAST, temperature cycling, and electromigration. The device features internal ESD protection exceeding 2000 V (HBM) and 150 V (machine model), and is specified for stable operation with capacitive loads up to 100 pF.

Pinout & Package
TLV2252QDREP is housed in an 8-pin SOIC (D) package with standard pinout for dual op-amps. Thermal and mechanical data comply with TI's SC-59 / SOIC-8 specifications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail capable, drives ADC inputs or low-power filters directly. |
| 2 | IN− A | Inverting input of Amp A - high-impedance node; sensitive to PCB leakage and layout parasitics. |
| 3 | IN+ A | Non-inverting input of Amp A - accepts signals down to VDD− (ground), enabling true single-supply DC coupling. |
| 4 | VDD− / GND | Negative supply / ground reference - serves as common return for both amplifiers and external circuitry. |
| 5 | IN+ B | Non-inverting input of Amp B - electrically isolated from Amp A; supports independent signal paths. |
| 6 | IN− B | Inverting input of Amp B - matched bias current and offset specs enable precision differential configurations. |
| 7 | OUT B | Amplifier B output - identical AC/DC performance to OUT A; allows dual-channel signal processing on one die. |
| 8 | VDD+ | Positive supply - accepts 2.7–8 V; internal regulation not required; quiescent current stable across range. |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| TLV2252AQDREP | Lower input offset voltage: 850 µV max (same spec) but tighter distribution; same package and pinout. | Preferred for precision DC-coupled applications requiring minimal initial calibration (e.g., medical diagnostics). | Select TLV2252AQDREP when VIO budget is ≤500 µV at system level; otherwise TLV2252QDREP offers identical functionality at Q-level reliability. |
| TLV2322IDR | Higher supply current (100 µA/ch), wider VIO range (2000 µV max), no extended temperature rating (−40°C to 85°C only). | Suitable for commercial-grade, cost-sensitive designs where extended temp is unnecessary. | Choose TLV2322IDR only for non-automotive/non-industrial use; TLV2252QDREP provides superior noise, power, and temperature robustness. |
Compared with TLV2252AQDREP, TLV2252QDREP trades tighter VIO distribution for enhanced DMS support and extended temperature qualification - making it preferable for long-lifecycle industrial deployments. Against TLV2322IDR, it delivers 3× lower power, 2× lower noise, and full −40°C to 125°C operation - justifying its use in mission-critical sensing.

FAQ
What is the maximum operating temperature range for TLV2252QDREP?
The TLV2252QDREP is qualified for continuous operation from −40°C to 125°C. This extended temperature range is verified per JEDEC standards including HAST, temperature cycling, and electromigration testing - confirming reliability in under-hood automotive and industrial control environments where thermal stress is severe. The device maintains all key specs, including 34 µA supply current and 850 µV max VIO, across this full range.
Does TLV2252QDREP support true single-supply operation with input signals referenced to ground?
Yes, TLV2252QDREP supports true single-supply operation: its common-mode input voltage range extends to VDD− (ground), and its output swings rail-to-rail. This allows direct DC-coupled amplification of 0–VDD sensor outputs - such as resistive bridge or thermistor signals - without external level-shifting circuitry. The input stage remains linear and stable even when IN+ or IN− is held at 0 V.
How does the noise performance of TLV2252QDREP compare to legacy micropower op-amps?
TLV2252QDREP delivers 19 nV/√Hz input voltage noise at 1 kHz - four times lower than previous-generation micropower CMOS op-amps. This improvement directly enhances signal-to-noise ratio in low-frequency sensor applications (e.g., environmental monitoring), enabling detection of sub-millivolt signals without additional gain stages that would amplify noise further. Measured noise is consistent across 3 V and 5 V supplies.
Is TLV2252QDREP pin-compatible with other dual op-amps in SOIC-8 packages?
TLV2252QDREP uses the industry-standard dual op-amp pinout for SOIC-8 (pin 1 = OUT A, pin 2 = IN− A, pin 3 = IN+ A, pin 4 = GND, pin 5 = IN+ B, pin 6 = IN− B, pin 7 = OUT B, pin 8 = VDD+). It is pin-compatible with TLV2252AQDREP, TLV2322IDR, and LMV358IDR - though electrical specs (VIO, IIB, noise, temp range) differ significantly between families.
What is the recommended capacitive load limit for stable operation of TLV2252QDREP?
TLV2252QDREP is characterized for stable unity-gain operation with capacitive loads up to 100 pF, as confirmed by phase margin (63°) and gain margin (15 dB) measurements at 25°C. For loads exceeding 100 pF, a series resistor (typically 10–50 Ω) should be placed between the output and capacitor to maintain stability - especially critical in ADC driver or filter applications where ringing must be avoided.
