Product details
Overview
TLC2252AIPWR from Texas Instruments is a dual rail-to-rail output, very low-power operational amplifier in an 8-pin TSSOP package. It delivers 35 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, and 850 µV maximum input offset voltage at 25°C - enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLC2252AIPWR datasheet, TLC2252AIPWR pinout, TLC2252AIPWR application, or TLC2252AIPWR equivalent, key selection criteria include its rail-to-rail output swing (±4.8 V at ±5 V supplies), common-mode input range extending to the negative rail, ultra-low input bias current (1 pA typ), and full characterization across –40°C to 125°C for industrial and automotive sensing systems.
Technical Context
The TLC2252AIPWR uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining micropower operation. Its input stage supports common-mode voltages down to the negative supply rail and operates with single-supply (2.2 V to 8 V) or split-supply (±2.2 V to ±8 V) configurations.
It features fully specified performance over –40°C to 125°C, including 70 dB minimum CMRR, 80 dB minimum PSRR, and 100 kΩ load-driven output capability. The device includes internal ESD protection and is characterized for stability with capacitive loads up to 100 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 35 µA per channel typ - enables multi-year battery life in always-on remote sensors. |
| Input Offset Voltage | 850 µV max at 25°C - supports DC-coupled amplification of mV-level transducer signals without nulling circuitry. |
| Input Bias Current | 1 pA typ - preserves signal integrity when amplifying high-impedance sources like piezoelectric or pH electrodes. |
| Input Voltage Noise | 19 nV/√Hz at 1 kHz - improves SNR in low-frequency sensor front-ends compared to prior-generation micropower op amps. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs with 0–5 V or ±2.5 V input ranges, minimizing headroom loss. |
| Common-Mode Input Range | Includes negative rail - allows direct interfacing with ground-referenced sensors in single-supply systems. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive and industrial control applications. |
Pinout & Package
Package: 8-pin TSSOP (PW), 3.0 mm × 4.4 mm, 0.65 mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input of amplifier A | High-impedance node accepting differential feedback or signal inversion; requires guarding in high-Z layouts. |
| 2 | Non-inverting input of amplifier A | Accepts high-impedance sensor inputs; common-mode range extends to V– (GND). |
| 3 | Output of amplifier A | Rail-to-rail capable output; drives 100 kΩ loads with <0.2 V headroom at ±5 V supplies. |
| 4 | Negative supply / GND | Reference for both amplifiers; must be low-impedance for noise-sensitive applications. |
| 5 | Positive supply | Supports 2.2 V to 8 V single supply or ±2.2 V to ±8 V split supply; decoupling required. |
| 6 | Inverting input of amplifier B | Independent input stage identical to Pin 1; no crosstalk between channels. |
| 7 | Non-inverting input of amplifier B | Matches Pin 2 functionality; enables dual-channel signal conditioning on one die. |
| 8 | Output of amplifier B | Functionally identical to Pin 3; supports independent gain stages or dual-sensor readout. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers >99% of supply rail-to-rail swing, maximizing ADC utilization in 3.3 V or 5 V systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432IDR | Higher supply current (600 µA/ch), higher slew rate (0.5 V/µs), but same rail-to-rail output and 850 µV VIO. | Requires more power; suited for higher-bandwidth sensor interfaces where speed outweighs battery life. | Select TLV2432IDR when >100 kHz closed-loop bandwidth is needed; TLC2252AIPWR remains optimal for sub-30 kHz, ultra-low-power designs. |
| OPA2333AIDR | Zero-drift architecture, 2 µV max VIO, but 17 µA/ch supply current and limited rail-to-rail output drive capability. | Better DC precision but reduced output swing margin into heavy loads; not rated for >105°C. | Choose OPA2333AIDR for µV-level DC stability in lab-grade instruments; TLC2252AIPWR better fits cost-sensitive, wide-temp industrial deployments. |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2252AIPWR uniquely balances micropower operation (35 µA/ch), rail-to-rail output, and extended temperature qualification - making it the preferred choice for long-life, thermally demanding embedded sensor nodes where precision and power coexist.

FAQ
What is the maximum operating supply voltage for the TLC2252AIPWR?
The TLC2252AIPWR supports a maximum supply voltage of ±8 V in split-supply mode or 8 V in single-supply mode. Absolute maximum ratings specify VDD+ ≤ 8 V and VDD– ≥ –8 V. Exceeding these limits risks permanent damage. Operation above ±5 V or 5 V is permitted but requires verification of output swing, CMRR, and PSRR degradation per the datasheet's electrical characteristics tables.
Does the TLC2252AIPWR support true rail-to-rail input?
No, the TLC2252AIPWR does not feature rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD–/GND) but stops 1.5 V below the positive rail (VDD+ – 1.5 V) under recommended operating conditions. This design enables robust performance with high open-loop gain and low input bias current using the Advanced LinCMOS™ process, while retaining rail-to-rail output swing.
Can the TLC2252AIPWR drive a 10 nF capacitive load stably?
The TLC2252AIPWR is characterized for stability with up to 100 pF capacitive loads when driving 50 kΩ resistive loads, as confirmed by phase margin (63°) and gain margin (15 dB) data at unity gain. Driving 10 nF directly violates this specification and will likely cause oscillation. For larger capacitive loads, use a series isolation resistor (e.g., 100 Ω–1 kΩ) between the TLC2252AIPWR output and the capacitor to restore stability.
How does the input offset voltage drift over temperature for the TLC2252AIPWR?
The TLC2252AIPWR has a temperature coefficient of input offset voltage (αVIO) of 0.5 µV/°C over 25°C to 85°C. With a maximum VIO of 850 µV at 25°C and 1000 µV over full range (–40°C to 125°C), the worst-case drift is bounded within ±150 µV across its operating temperature span - verified by testing and consistent with its TLC2252A grade designation.
Is the TLC2252AIPWR pin-compatible with the TLC2252CPW?
Yes, the TLC2252AIPWR and TLC2252CPW share identical 8-pin TSSOP (PW) packaging and pinout. However, they differ in performance grade: the 'A' suffix denotes the enhanced 850 µV max VIO variant qualified for –40°C to 125°C operation, whereas the 'C' suffix is rated for 0°C to 70°C with 1500 µV max VIO. Electrical and thermal specifications are not interchangeable; system-level validation is required when substituting.
