Product details
Overview
TLC2252AIP from Texas Instruments is a dual rail-to-rail output, micropower operational amplifier in an 8-pin plastic DIP package, specified for –40°C to 125°C operation with maximum input offset voltage of 850 µV at 25°C, 35 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, and common-mode input range extending to the negative rail. It serves precision signal conditioning in battery-powered sensor interfaces and low-voltage data acquisition systems.
For engineers reviewing the TLC2252AIP datasheet, TLC2252AIP pinout, TLC2252AIP application, or TLC2252AIP equivalent, this page delivers verified electrical specifications, thermal operating limits, rail-to-rail output behavior under single- and split-supply conditions, and validated alternative options for industrial temperature-range op-amp replacement.
Technical Context
The TLC2252AIP uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining ultra-low input bias current (1 pA typ) and low noise-critical for high-impedance source amplification. Its input stage supports common-mode voltages down to the negative supply rail, enabling true single-supply operation without level-shifting circuitry.
Designed as a performance upgrade over TLC27L2 and TS27L2, the TLC2252AIP delivers improved dynamic range, lower input offset voltage (850 µV max vs. 1500 µV in standard TLC2252), and enhanced noise performance-making it suitable for precision analog front-ends where power budget and DC accuracy are tightly constrained.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2252IP | Same pinout and architecture, but 1500 µV max VIO (vs. 850 µV) and rated for –40°C to 125°C with looser DC specs. | Acceptable where system-level calibration compensates for higher offset; not suitable for uncalibrated 12-bit+ precision. | Select TLC2252IP only if cost sensitivity outweighs need for guaranteed low-offset performance across temperature. |
| TLV2432IDR | Higher supply current (600 µA/ch), wider GBW (2.2 MHz), but same 8-pin SOIC package and –40°C to 125°C rating. | Better for AC-coupled, higher-bandwidth applications (e.g., active filters); unsuitable for µA-level power budgets. | Choose TLV2432IDR when slew rate (>0.5 V/µs) or bandwidth >100 kHz is required - not for micropower use cases. |
Compared with TLC2252IP, the TLC2252AIP provides tighter input offset voltage control essential for uncalibrated precision; compared with TLV2432IDR, it trades bandwidth and drive strength for 17× lower quiescent current - making it optimal for always-on, battery-constrained nodes.

FAQ
What is the maximum supply voltage for the TLC2252AIP?
The TLC2252AIP supports a maximum supply voltage of ±8 V for split-supply operation or +16 V for single-supply configurations. Absolute maximum ratings specify VDD+ ≤ 8 V and VDD– ≥ –8 V relative to midpoint; exceeding these risks permanent device damage. Recommended operating range is ±2.2 V to ±8 V or +4.4 V to +16 V, with full electrical characterization at ±5 V and 5 V.
Does the TLC2252AIP support true single-supply operation with inputs referenced to ground?
Yes, the TLC2252AIP supports true single-supply operation: its common-mode input voltage range includes the negative rail (VDD–/GND), allowing inputs to be referenced directly to ground. This enables direct interfacing with ground-referenced sensors like thermistors or bridge circuits without level-shifting circuitry - a key advantage over older op-amps requiring input bias above GND.
How does the input offset voltage of the TLC2252AIP compare to the standard TLC2252IP?
The TLC2252AIP guarantees a maximum input offset voltage of 850 µV at 25°C, whereas the TLC2252IP has a maximum of 1500 µV under identical conditions. Both share the same –40°C to 125°C operating range, but the 'A' suffix denotes tighter DC specifications - critical for applications requiring <1 LSB error in 12-bit systems without factory calibration.
Can the TLC2252AIP drive ADC inputs directly without external level-shifting components?
Yes, the TLC2252AIP's rail-to-rail output swing enables direct connection to SAR and sigma-delta ADC inputs. At light loads, it achieves output voltages within 10 mV of both supply rails - fully utilizing the ADC's input range when powered from the same supply. This eliminates external level-shifters, reduces component count, and improves system accuracy by avoiding additional offset and noise sources.
Is the TLC2252AIP suitable for automotive under-hood applications?
Yes, the TLC2252AIP is qualified for automotive under-hood use: it is rated for –40°C to 125°C operation, features robust ESD protection, and is listed in TI's Q-TEMP automotive-grade product line. Its low power consumption (35 µA/ch), rail-to-rail output, and stable DC performance across temperature make it appropriate for engine control sensors, exhaust gas monitoring, and battery management signal conditioning.
