Product details
Overview
TLC252CPE4 from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for low-power, single-supply operation across 1.4 V to 16 V. It features 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 TLC252CPE4 datasheet, TLC252CPE4 pinout, TLC252CPE4 application, or TLC252CPE4 equivalent, this device is selected for ultra-low quiescent current (3.6 mA typ @ 5 V), wide supply flexibility (1.4–16 V), and stable unity-gain operation in energy-constrained analog front-ends where input bias current <60 pA and offset drift <2 µV/°C are critical.
Technical Context
The TLC252CPE4 implements a silicon-gate LinCMOS™ process to achieve extremely high input impedance (>1012 Ω) and sub-60 pA input bias current, making it suitable for high-impedance transducer interfacing and passive filter buffering. Its input stage operates down to the negative rail (GND), supporting true single-supply configurations without level-shifting circuitry.
It delivers 1.7 MHz unity-gain bandwidth and 3.6 V/µs slew rate at 5 V, with phase margin of 46° - ensuring stability in gain-of-one configurations. The device is characterized for 0°C to 70°C operation and includes internal ESD protection rated to 2000 V per MIL-STD-883C Method 3015.1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct operation from single alkaline, Li-ion, or solar cells without regulation. |
| Input Offset Voltage (max) | 10 mV at 25°C - defines worst-case DC error in precision DC-coupled amplifiers and active filters. |
| Supply Current (typ) | 3.6 mA at 5 V (both amps) - supports multi-day battery life in always-on monitoring systems. |
| Unity-Gain Bandwidth | 1.7 MHz at 5 V - sufficient for audio preamps, anti-aliasing filters, and medium-speed sensor signal chains. |
| Common-Mode Input Range | Includes GND (VDD–/GND) - eliminates need for input biasing networks in single-supply designs. |
| Input Bias Current (max) | 600 pA at 70°C - preserves accuracy when driving high-value feedback resistors (>1 MΩ). |
| ESD Rating | 2000 V HBM - reduces risk of handling damage during PCB assembly and prototyping. |
Pinout & Package
Package: 8-pin plastic DIP (P package), through-hole mount, 0.3-inch width, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier 1 (1OUT) | Provides buffered, low-impedance output signal; drives loads up to 10 kΩ without significant gain loss. |
| 2 | Inverting Input of Amplifier 1 (1IN–) | Accepts feedback or differential input signals; high-impedance node sensitive to stray capacitance. |
| 3 | Non-Inverting Input of Amplifier 1 (1IN+) | Reference input for follower or non-inverting gain stages; must be decoupled if high-frequency noise is present. |
| 4 | Negative Supply / Ground (VDD–/GND) | Return path for both amplifiers; serves as reference for single-supply operation and must be low-impedance. |
| 5 | Positive Supply (VDD) | Power input for both amplifiers; requires local 0.1 µF ceramic bypass capacitor near pin. |
| 6 | Output of Amplifier 2 (2OUT) | Independent output channel; usable for dual-path signal processing or cascaded gain stages. |
| 7 | Inverting Input of Amplifier 2 (2IN–) | Second high-impedance input node; isolated from Channel 1 except via shared supply and ground paths. |
| 8 | Non-Inverting Input of Amplifier 2 (2IN+) | Second reference input; supports independent configuration (e.g., one channel as buffer, one as comparator driver). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends to VDD–/GND, enabling zero-input-voltage operation without external biasing resistors. |
| Ultra-low input bias current | ≤600 pA max at 70°C - preserves signal integrity in photodiode, piezoelectric, and pH electrode interfaces. |
| Stable at unity gain | 46° phase margin ensures reliable operation in voltage-follower configurations without external compensation. |
| Low-noise performance | 25 nV/√Hz input voltage noise at 1 kHz - suitable for amplifying microvolt-level sensor outputs. |
| Wide supply voltage range | Operates from 1.4 V (single cell) to 16 V - eliminates need for separate LDOs in mixed-voltage systems. |

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 only | Better DC precision but incompatible with ultra-low-power (<10 µA) sleep modes | Select when offset-critical DC gain accuracy outweighs battery life requirements |
| LMV358M/NOPB | Higher VIO (7 mV max), lower cost, wider temp range (–40°C to 125°C), same 8-pin DIP package | Less suitable for precision sensor front-ends but robust for industrial control I/O modules | Select when extended temperature operation and cost sensitivity dominate over input offset specs |
Compared with TLV2462CP and LMV358M/NOPB, the TLC252CPE4 provides superior input bias current (<600 pA) and lower supply current (3.6 mA vs. 1.1 mA for TLV2462CP and 170 µA for LMV358), making it uniquely suited for long-life, high-impedance, single-supply analog sensing where leakage and quiescent power are design constraints.

FAQ
What is the maximum input offset voltage specification for TLC252CPE4 at 25°C?
The TLC252CPE4 has a maximum input offset voltage of 10 mV at 25°C, as specified in the "TLC252_C" column of the electrical characteristics table under VDD = 5 V test conditions. This value applies across the commercial temperature range (0°C to 70°C) with a worst-case limit of 12 mV.
Does TLC252CPE4 support true single-supply operation with input signals referenced to ground?
Yes, the TLC252CPE4 supports true single-supply operation: its common-mode input voltage range extends to the negative rail (VDD–/GND), allowing inputs to swing down to 0 V. This eliminates the need for input biasing networks when interfacing grounded sensors or DAC outputs.
What is the typical supply current consumption of TLC252CPE4 at 5 V?
The TLC252CPE4 draws 3.6 mA typical supply current (for both amplifiers combined) at VDD = 5 V and TA = 25°C, as measured under no-load conditions with VO = 2.5 V and VIC = 2.5 V. At 70°C, the maximum is 2.6 mA, confirming excellent thermal stability.
Can TLC252CPE4 drive a 10-kΩ load while maintaining specified gain accuracy?
Yes - the TLC252CPE4 is characterized with RL = 10 kΩ in key specifications (e.g., AVD, VOH/VOL). At 5 V supply, it delivers VOH ≥ 3 V and VOL ≤ 50 mV into 10 kΩ, supporting standard logic-level interfacing and active filter implementations without gain degradation.
Is TLC252CPE4 pin-compatible with other variants in the TLC25x2 family?
Yes - all TLC252, TLC25L2, and TLC25M2 variants in the P (DIP), D (SOIC), and PW (TSSOP) packages share identical 8-pin layouts and pin functions. The TLC252CPE4 is functionally and physically interchangeable with TLC252ACP, TLC252BCP, and TLC25L2CP in the same package, differing only in VIO grade and bias current.
