Product details
Overview
TLC252CP from Texas Instruments is a LinCMOS™ dual operational amplifier in an 8-pin plastic DIP package, designed for low-power, single-supply operation down to 1.4 V. It delivers 10 mV max input offset voltage (25°C), 3.6 mA typical supply current at 5 V, and rail-to-rail common-mode input range extending to the negative rail - enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLC252CP datasheet, TLC252CP pinout, TLC252CP application, or TLC252CP equivalent, this page provides verified technical context, validated pin functions, real-world application mappings, and two confirmed alternative parts with documented functional trade-offs for design-in decisions under low-voltage, low-quiescent-current constraints.
Technical Context
The TLC252CP uses Texas Instruments' silicon-gate LinCMOS™ process to achieve ultra-low input bias currents (≤60 pA typ at 25°C) and stable input offset voltage across temperature (1.8 µV/°C avg coefficient). Its architecture supports true single-supply operation with input common-mode range including ground and output swing within 50 mV of rails.
It is internally compensated for unity-gain stability, features ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.1), and operates across 0°C to 70°C. The device is not optimized for high-speed applications - its unity-gain bandwidth is 1.7 MHz (typ at VDD = 5 V), and slew rate is 2.9 V/µs (typ).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct use with single alkaline, lithium, or NiMH cells without regulation. |
| Input Offset Voltage (max) | 10 mV at 25°C - defines worst-case DC error in precision gain stages or active filters. |
| Supply Current (two amps) | 3.6 mA typ at VDD = 5 V - suitable for moderate-duty-cycle portable systems where µA-level current is not required. |
| Input Bias Current (max) | 600 pA over 0°C–70°C - preserves accuracy in high-impedance transducer interfaces (e.g., pH electrodes, photodiode TIA feedback). |
| Common-Mode Input Range | Includes VDD–/GND - allows direct sensing of signals referenced to ground in single-supply configurations. |
| Unity-Gain Bandwidth | 1.7 MHz typ at VDD = 5 V - supports audio-band filtering, slow-control-loop compensation, and DC-coupled buffering. |
| ESD Rating | 2000 V HBM - meets basic handling robustness for non-automotive industrial assembly environments. |
Pinout & Package
Package: 8-pin plastic DIP (P package), 0.3-inch width, through-hole mountable. RoHS-compliant lead finish per TI documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier 1 (1OUT) | Low-impedance voltage source; drives loads ≥10 kΩ without significant gain error. |
| 2 | Inverting Input of Amplifier 1 (1IN–) | Differential node; high-impedance (≥10¹² Ω) - sensitive to stray capacitance and leakage paths. |
| 3 | Non-Inverting Input of Amplifier 1 (1IN+) | Differential node; identical impedance and bias behavior as Pin 2. |
| 4 | Ground / Negative Supply (VDD–/GND) | Reference return for both amplifiers and all external circuitry; must be low-impedance. |
| 5 | Positive Supply (VDD) | Single or dual supply rail; decoupling capacitor (0.1 µF) required within 1 cm for stability. |
| 6 | Output of Amplifier 2 (2OUT) | Independent output stage; no crosstalk specified - usable for dual-path signal processing. |
| 7 | Inverting Input of Amplifier 2 (2IN–) | Functionally identical to Pin 2; isolated from Amp 1 except via shared supply/ground. |
| 8 | Non-Inverting Input of Amplifier 2 (2IN+) | Functionally identical to Pin 3; maintains same input characteristics across both channels. |
Key Features
| Feature | Design Value |
|---|---|
| LinCMOS™ Process Technology | Enables picoampere-level input bias current and stable offset voltage without trimming - reduces calibration overhead in production. |
| True Single-Supply Operation | Input common-mode range includes GND and output swings to within 50 mV of GND - eliminates need for split supplies in portable data loggers. |
| Wide Supply Range (1.4 V–16 V) | Supports direct connection to unregulated battery stacks (e.g., 2×AA, 3×NiMH) while maintaining functionality across discharge curve. |
| Internal Unity-Gain Compensation | Guarantees stability without external compensation components - simplifies layout and reduces BOM count in low-frequency designs. |
| ESD Protection (2000 V HBM) | Reduces risk of field failure during manual handling or board-level test - lowers qualification burden for Class 1B assembly lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462CP | Lower VIO (2 mV max), higher supply current (550 µA/amp), rail-to-rail output (TLC252CP is not RRO). | Better DC precision but higher power - suited for 3.3 V systems where output headroom is critical. | Select TLV2462CP when output swing to within 10 mV of rails is required and supply current budget allows ≥1.1 mA. |
| LM358AP | Higher VIO (7 mV max), bipolar input (nA bias current), wider temp range (−25°C to 85°C), no LinCMOS™ low-IIB benefit. | Lower cost and broader availability - acceptable where input impedance >1 MΩ is sufficient and DC error <10 mV is tolerable. | Select LM358AP for cost-sensitive industrial controls where high-Z sources are absent and 1.4 V operation is not needed. |
Compared with TLV2462CP and LM358AP, the TLC252CP uniquely balances ultra-low input bias current (≤60 pA), 1.4 V minimum supply, and 10 mV VIO grade - making it optimal for high-impedance, battery-constrained designs where LM358AP's bias current would cause error and TLV2462CP's power draw exceeds budget.

FAQ
What is the maximum supply voltage rating for the TLC252CP?
The TLC252CP has an absolute maximum supply voltage of 18 V, as specified in the Absolute Maximum Ratings table. However, its recommended operating range is 1.4 V to 16 V. Exceeding 16 V may compromise long-term reliability or parametric performance, especially at elevated temperatures. Always observe derating curves in the Dissipation Rating Table for thermal management at high VDD and ambient conditions.
Does the TLC252CP support rail-to-rail output swing?
No, the TLC252CP does not provide rail-to-rail output. At VDD = 5 V and RL = 10 kΩ, its typical high-level output voltage (VOH) is 3.8 V and low-level output voltage (VOL) is 50 mV - meaning it swings to within ~1.2 V of VDD and ~50 mV above GND. This limitation must be accounted for in output stage design, particularly when interfacing with 5 V logic or ADC reference levels.
Can the TLC252CP operate from a single 1.5 V alkaline cell?
Yes, the TLC252CP is explicitly characterized for operation down to 1.4 V, making it compatible with a fresh 1.5 V alkaline cell. At 1.4 V, it delivers usable gain (AVD ≥10 V/mV), common-mode input range from GND to 0.2 V, and IDD ≈375 µA (typ). Performance degrades gradually as voltage drops below 1.4 V, but functional operation continues until ~1.2 V depending on load and temperature.
What is the input offset voltage specification for the TLC252CP across temperature?
The TLC252CP has a maximum input offset voltage of 12 mV over the full 0°C to 70°C operating range, with a typical value of 10 mV at 25°C. Its average temperature coefficient is 1.8 µV/°C, meaning offset drift contributes ≤0.1 mV over a 55°C span - a key advantage over bipolar op-amps in thermally varying environments like outdoor sensors.
Is the TLC252CP pin-compatible with other devices in the TLC25x2 family?
Yes, all variants in the TLC252, TLC25L2, and TLC25M2 families share identical 8-pin DIP (P), SOIC (D), and TSSOP (PW) footprints and pinouts. The TLC252CP is functionally interchangeable with TLC252ACP and TLC252BCP at the board level - only VIO grade and supply current differ. No PCB changes are required when upgrading to tighter offset grades.
