Product details
Overview
TLC2252ID from Texas Instruments is a dual rail-to-rail output, very low-power operational amplifier optimized for battery-powered and high-impedance signal conditioning applications. It delivers 35 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and rail-to-rail output swing from ±2.2 V to ±8 V supplies. It operates across –40°C to 125°C and supports single- or split-supply configurations in industrial sensor front-ends.
For engineers reviewing the TLC2252ID datasheet, TLC2252ID pinout, TLC2252ID application, or TLC2252ID equivalent, this page provides verified electrical specifications, package mapping to SOIC-8 (D), thermal derating data, real-world use cases in piezoelectric sensing and ADC interfacing, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLC2252ID 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 (19 nV/√Hz). Its input stage includes common-mode range extending to the negative rail, enabling true single-supply operation down to 0 V ground reference.
It features fully characterized performance over –40°C to 125°C, with maximum input offset voltage of 1500 µV (standard grade) and guaranteed operation up to ±8 V supply. The device exhibits 63° phase margin and 15 dB gain margin under standard 50 kΩ/100 pF load conditions, ensuring stable unity-gain buffer operation.

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 drive capability (100 mA short-circuit), wider input voltage range (to VDD– + 0.1 V), but higher supply current (600 µA/channel) | Better suited for driving heavy capacitive loads or low-impedance ADCs; not viable for multi-year battery operation | Select TLV2432IDR only when output drive or speed (1.5 MHz GBW) outweighs power budget constraints |
| OPA2333AIDR | Zero-drift architecture, 10 µV max VIO, 0.1 µV/°C drift, but 17 µA/channel supply current and narrower supply range (1.8–5.5 V) | Ideal for precision DC-coupled measurements where long-term drift matters more than absolute noise floor | Choose OPA2333AIDR when offset stability over temperature and time is critical, and supply is constrained to ≤5.5 V |
Compared with TLC2252ID, TLV2432IDR trades 17× higher quiescent current for stronger output drive, while OPA2333AIDR reduces input offset by 99% but restricts supply voltage and increases cost-making TLC2252ID optimal for cost-sensitive, wide-supply, battery-operated rail-to-rail signal chains.

FAQ
What is the maximum supply voltage rating for the TLC2252ID?
The TLC2252ID has an absolute maximum supply voltage rating of ±8 V for split-supply operation or 16 V for single-supply operation. Operation beyond these limits risks permanent damage. Recommended operating range is ±2.2 V to ±8 V or 4.4 V to 16 V, with full specification compliance across –40°C to 125°C ambient.
Does the TLC2252ID support true single-supply operation with input signals down to ground?
Yes, the TLC2252ID supports true single-supply operation: its common-mode input voltage range extends to the negative rail (VDD–/GND), and its output swings rail-to-rail. This allows direct interface with grounded sensors and full utilization of ADC input range without external biasing networks.
How does the input offset voltage of TLC2252ID compare to the TLC2252AID variant?
The TLC2252ID has a maximum input offset voltage of 1500 µV at 25°C, while the TLC2252AID variant is precision-trimmed to 850 µV max at 25°C. Both share identical packaging, temperature range (–40°C to 125°C), and core specifications-only VIO and its drift differ.
Can the TLC2252ID drive capacitive loads directly, and what is its phase margin?
The TLC2252ID maintains 63° phase margin and 15 dB gain margin with a 100 pF capacitive load and 50 kΩ resistive load at unity gain. It can drive moderate capacitive loads directly, but for >100 pF or low-impedance ADC inputs, external isolation resistors are recommended to ensure stability.
Is the TLC2252ID pin-compatible with older TI op-amps like the TLC27L2?
Yes, the TLC2252ID is pin-compatible with the TLC27L2 in SOIC-8 (D) package. It serves as a direct performance upgrade-offering rail-to-rail output, 4× lower noise (19 nV/√Hz vs. ~75 nV/√Hz), lower input offset voltage, and reduced supply current-without requiring PCB layout changes.
