Product details
Overview
TLC252ACD from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for low-power, single-supply operation with 5-mV maximum input offset voltage (VIO), 1.4 V to 16 V supply range, and rail-to-rail common-mode input down to the negative rail - ideal for battery-powered sensor signal conditioning and portable instrumentation.
For engineers reviewing the TLC252ACD datasheet, TLC252ACD pinout, TLC252ACD application, or TLC252ACD equivalent, this device delivers verified low-input-bias-current amplification (≤60 pA typ), stable unity-gain bandwidth (1.7 MHz at VDD = 5 V), and ESD-protected operation up to 2000 V per MIL-STD-883C Method 3015.1.
Technical Context
The TLC252ACD employs Texas Instruments' silicon-gate LinCMOS™ process to achieve ultra-high input impedance (>10¹² Ω), extremely low input bias and offset currents (≤60 pA/≤300 pA), and stable VIO across temperature (1.8 µV/°C avg). It supports true single-supply operation with common-mode input extending to GND.
Its internal electrostatic discharge (ESD) protection network prevents catastrophic failure at ±2000 V, and it is characterized for 0°C to 70°C commercial operation in an 8-pin SOIC (D) package. The device is unity-gain stable and exhibits 46° phase margin at 5 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Lower VIO (2 mV max), higher supply current (550 µA per amp), rail-to-rail output (TLC252ACD is not RRO) | Better DC accuracy but higher power; requires 2.7 V min supply - unsuitable for sub-2.7 V battery operation | Select TLV2462IDR only if RRO and tighter VIO outweigh supply voltage and current constraints. |
| LMV358IDR | Higher VIO (7 mV max), lower cost, 2.7 V min supply, no ESD rating specified | Acceptable for non-critical AC-coupled apps; lacks 1.4 V operation and documented 2000 V HBM protection | Choose LMV358IDR for cost-sensitive, line-powered designs where ultra-low voltage and ESD robustness are not required. |
Compared with TLV2462IDR and LMV358IDR, the TLC252ACD uniquely supports 1.4 V operation, offers guaranteed 2000 V HBM ESD protection, and maintains 5-mV VIO at sub-2 V supplies - making it irreplaceable in ultra-low-voltage, battery-constrained, or harsh-handling environments.

FAQ
What is the maximum input offset voltage specification for the TLC252ACD?
The TLC252ACD is an A-suffix variant with a maximum input offset voltage (VIO) of 5 mV at 25°C and 6.5 mV across the full 0°C to 70°C operating range. This grade is selected for applications requiring better DC accuracy than the standard TLC252CD (10 mV max) but without the cost premium of the B-suffix (2 mV max). The TLC252ACD maintains this VIO spec across its entire 1.4 V to 16 V supply range.
Does the TLC252ACD support true single-supply operation with input signals referenced to ground?
Yes, the TLC252ACD supports true single-supply operation: its common-mode input voltage range includes the negative rail (GND) across all supply voltages (e.g., –0.2 V to 3.5 V at VDD = 5 V). This allows direct amplification of ground-referenced sensor outputs - such as thermocouples or resistive bridge midpoints - without external level-shifting circuitry, simplifying design and reducing component count in the TLC252ACD-based signal chain.
What is the unity-gain bandwidth of the TLC252ACD at 5 V supply?
The TLC252ACD has a typical unity-gain bandwidth (B1) of 1.7 MHz at VDD = 5 V and TA = 25°C, with a minimum of 1.3 MHz across the full 0°C to 70°C temperature range. This bandwidth is measured under standard test conditions (VI = 10 mV, CL = 20 pF) and confirms stable operation in unity-gain buffer and active filter configurations without external compensation - a key design assurance for the TLC252ACD in precision analog circuits.
Is the TLC252ACD pin-compatible with other devices in the TLC25x2 family?
Yes, the TLC252ACD shares identical 8-pin SOIC (D) pinout and footprint with all members of the TLC25x2 family - including TLC252CD, TLC252BCD, TLC25L2ACD, and TLC25M2ACD. This allows direct substitution within the same package variant for VIO grade, bandwidth, or supply current trade-offs - provided system-level validation confirms compatibility with the specific electrical characteristics (e.g., slew rate, noise, CMRR) required by the application using the TLC252ACD.
What ESD protection does the TLC252ACD provide, and how is it tested?
The TLC252ACD incorporates internal electrostatic discharge (ESD) protection circuits rated to withstand 2000 V human-body-model (HBM) stress, as tested per MIL-STD-883C, Method 3015.1. This protection applies to all pins and is inherent to the LinCMOS™ process design. While this prevents catastrophic failure, TI recommends standard ESD handling precautions during assembly, as repeated exposure may degrade parametric performance over time - a critical consideration for high-reliability deployment of the TLC252ACD.
