Product details
Overview
TLV2252ID from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage, micropower applications. It delivers 34 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing from 2.7 V to 8 V supply - enabling high dynamic range signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLV2252ID datasheet, TLV2252ID pinout, TLV2252ID application, or TLV2252ID equivalent, key selection criteria include its 850 µV max input offset voltage (TLV2252AI grade), 1 pA typical input bias current, and guaranteed operation from −40°C to 125°C in the SOIC-8 package - critical for precision analog front-ends in automotive and industrial monitoring systems.
Technical Context
The TLV2252ID uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining CMOS-level input impedance (>10¹² Ω) and ultra-low input bias current. Its input stage operates with common-mode voltage extending to the negative rail, supporting single-supply configurations where ground-referenced sensors are used.
Internally compensated for unity-gain stability, it provides 0.187 MHz gain-bandwidth product and 0.07 V/µs slew rate at 3 V, with phase margin of 63° into 50 kΩ//100 pF loads - ensuring robust performance in low-frequency precision amplification without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - supports direct integration with Li-ion, 3.3 V, and 5 V systems without level-shifting. |
| Input Offset Voltage (Max) | 850 µV at TA = 25°C - enables accurate DC-coupled amplification of mV-level sensor outputs. |
| Supply Current (Per Channel) | 34 µA typ - allows continuous operation for years on coin-cell batteries in remote sensing nodes. |
| Input Voltage Noise | 19 nV/√Hz at f = 1 kHz - 4× lower than prior micropower CMOS op amps, reducing noise floor in high-gain stages. |
| Output Swing | Rail-to-rail - delivers full 0 V to VDD output range, maximizing ADC utilization in single-supply data acquisition. |
| Input Bias Current | 1 pA typ - preserves signal integrity when amplifying from high-impedance sources like piezoelectric transducers. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
TLV2252ID is housed in an 8-pin SOIC (D) package with standard pinout compatible with industry-wide PCB footprints. Thermal pad is not present; power dissipation is managed via package surface area and board copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to ±50 mA; rail-to-rail swing ensures maximum signal headroom. |
| 2 | IN− A | Inverting input of Amplifier A - high-impedance node (10¹² Ω) minimizes loading on source networks. |
| 3 | IN+ A | Non-inverting input of Amplifier A - accepts common-mode voltages down to VDD− (ground). |
| 4 | VDD− / GND | Negative supply / ground reference - serves as return path for both amplifiers and bias circuitry. |
| 5 | IN+ B | Non-inverting input of Amplifier B - electrically isolated from Amp A; supports dual-channel independent signal paths. |
| 6 | IN− B | Inverting input of Amplifier B - matched input characteristics to Pin 2 ensure consistent channel performance. |
| 7 | OUT B | Amplifier B output - identical AC/DC specs to Pin 1; enables differential drive or parallel gain staging. |
| 8 | VDD+ | Positive supply - powers both amplifiers; supply rejection ratio (kSVR) is 80 dB min over full voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Enables full-scale signal capture into 12-bit+ ADCs without supply headroom loss in 3.3 V systems. |

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 |
|---|---|---|---|
| TLV2252AID | Same SOIC-8 package and pinout; tighter 850 µV max VIO (vs. 1500 µV for TLV2252ID) at 25°C. | Better DC accuracy for precision sensor front-ends requiring minimal calibration. | Select TLV2252AID when offset-limited error budget demands ≤850 µV VIO at room temperature. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C max drift vs. 0.5 µV/°C for TLV2252ID; higher 35 µA/channel current. | Superior long-term DC stability in uncalibrated systems exposed to wide temperature cycling. | Choose OPA2333AID for applications needing <1 µV total drift over −40°C to 125°C, accepting slightly higher power. |
Compared with TLV2252AID, TLV2252ID trades initial offset accuracy for broader availability and cost efficiency in non-critical DC applications; versus OPA2333AID, it offers lower quiescent current and simpler biasing but lacks auto-zero correction for ultra-stable DC gain.

FAQ
What is the maximum operating temperature range for the TLV2252ID?
The TLV2252ID is rated for continuous operation from −40°C to +125°C ambient temperature. This specification is validated per the recommended operating conditions table in the official datasheet (SLOS185D), making TLV2252ID suitable for under-hood automotive and industrial control applications where thermal stress is a primary design constraint.
Does the TLV2252ID support true rail-to-rail input capability?
No, the TLV2252ID features rail-to-rail *output* swing but only extends its common-mode input voltage range to the negative rail (VDD−). The positive end of the input range is limited to VDD+ −1.3 V at 3 V supply, meaning it does not accept inputs all the way to VDD+. This behavior is explicitly defined in the "Recommended Operating Conditions" section of the TLV2252ID datasheet.
What is the typical supply current per channel for TLV2252ID at 3 V operation?
The TLV2252ID draws 34 µA per channel typical supply current at VDD = 3 V and TA = 25°C, as specified in the "Electrical Characteristics" tables of the SLOS185D datasheet. This value remains stable across the full −40°C to 125°C temperature range, with a maximum of 150 µA per channel under worst-case conditions.
Can TLV2252ID drive capacitive loads directly?
The TLV2252ID is internally compensated for unity-gain stability with resistive loads up to 50 kΩ and capacitive loads up to 100 pF, as confirmed by phase margin (63°) and gain margin (15 dB) measurements in the datasheet. Driving larger capacitive loads (>100 pF) requires external isolation resistor or feedback network adjustment to prevent peaking or oscillation.
Is TLV2252ID pin-compatible with older TI op amps like TLV2322?
Yes, TLV2252ID is pin-compatible with TLV2322 in the same SOIC-8 package. However, TLV2252ID improves upon TLV2322 with rail-to-rail output swing, lower noise (19 nV/√Hz vs. ~30 nV/√Hz), and reduced input offset voltage - making it a direct functional upgrade in existing designs without PCB changes.
