Product details
Overview
TLC252CD from Texas Instruments is a LinCMOS™ dual operational amplifier in an 8-pin SOIC (D) package, designed for low-power, single-supply operation from 1.4 V to 16 V. It delivers 10 mV max input offset voltage at 25°C, 30 nV/√Hz typical input noise at 1 kHz, and stable unity-gain performance-ideal for battery-powered sensor signal conditioning and portable analog front-ends.
For engineers reviewing the TLC252CD datasheet, TLC252CD pinout, TLC252CD application, or TLC252CD equivalent, this page provides verified electrical specifications, validated SOIC-D package details, confirmed temperature range (0°C to 70°C), and two functionally comparable alternatives with documented parameter differences for precision analog design.
Technical Context
The TLC252CD uses Texas Instruments' silicon-gate LinCMOS™ process to achieve extremely high input impedance (>1012 Ω), ultra-low input bias current (≤60 pA typ at 25°C), and rail-to-rail common-mode input range extending to the negative supply rail. Its internal ESD protection withstands 2000 V per MIL-STD-883C Method 3015.1.
It operates across three bias grades (TLC252, TLC25L2, TLC25M2), with the TLC252CD specifically configured as the standard-bias variant-offering balanced performance between supply current (1.4–3.2 mA at VDD = 5 V), slew rate (2.9–3.6 V/µs), and unity-gain bandwidth (1.7 MHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct use with single-cell Li-ion, alkaline, or solar-cell sources without regulation |
| Input Offset Voltage (max) | 10 mV at 25°C - defines worst-case DC error in precision gain stages and active filters |
| Input Bias Current (typ) | 60 pA at 25°C - supports high-impedance transducer interfaces (e.g., pH electrodes, piezoresistive sensors) |
| Unity-Gain Bandwidth | 1.7 MHz at VDD = 5 V - sufficient for audio preamps, anti-aliasing filters, and medium-speed instrumentation |
| Common-Mode Input Range | Includes negative rail (–0.2 V to VDD – 1 V) - allows true single-supply operation with ground-referenced inputs |
| ESD Rating | 2000 V HBM - meets industrial handling requirements without external protection circuitry |
Pinout & Package
Package: 8-pin SOIC (D), 3.9 mm × 4.9 mm body, 1.27 mm pitch, plastic, surface-mount. RoHS-compliant and tape-and-reel compatible (suffix R).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives loads up to 10 kΩ with rail-swing capability |
| 2 | IN– A | Inverting input - high-impedance node; sensitive to layout-induced leakage currents |
| 3 | IN+ A | Non-inverting input - accepts signals down to VDD–/GND; critical for reference buffering |
| 4 | VDD–/GND | Negative supply or ground reference - shared return path for both amplifiers |
| 5 | VDD | Positive supply - powers both op-amps; bypass capacitor required at pin |
| 6 | OUT B | Second amplifier output - independent channel for dual-path signal processing |
| 7 | IN– B | Inverting input of second amplifier - enables differential pair or dual-stage configurations |
| 8 | IN+ B | Non-inverting input of second amplifier - supports matched dual-channel applications |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC272CD | Higher VIO (15 mV max), higher supply current (1.2–2.5 mA), same SOIC-D package | Less suitable for precision DC-coupled paths but more robust in noisy industrial environments | Select when cost sensitivity outweighs offset-critical performance and wider supply margin (up to 16 V) is needed |
| LMV358IDR | Lower VIO (3 mV max), rail-to-rail output, 80 µA supply current, same pinout | Better for low-voltage (<3 V) systems and dynamic signal chains requiring full output swing | Choose for modern ultra-low-power designs where 1.4 V operation is unnecessary and output swing to rails is mandatory |
Compared with TLC252CD, TLC272CD trades offset accuracy for ruggedness and broader AC performance, while LMV358IDR offers superior DC precision and rail-to-rail output at significantly lower quiescent current-but lacks the 1.4 V minimum supply capability critical for legacy battery chemistries.

FAQ
What is the maximum input offset voltage specification for TLC252CD at 25°C?
The TLC252CD has a maximum input offset voltage of 10 mV at 25°C, as specified in the "Available Options" table and confirmed in the electrical characteristics section for TLC252_C grade devices. This value applies across the full commercial temperature range (0°C to 70°C) with a worst-case of 12 mV.
Does TLC252CD support true single-supply operation with inputs referenced to ground?
Yes, the TLC252CD supports true single-supply operation: its common-mode input voltage range includes the negative rail (VDD–/GND), extending down to –0.2 V at VDD = 5 V. This allows direct connection of ground-referenced sensors without level-shifting circuitry-confirmed in the recommended operating conditions table.
What is the unity-gain bandwidth of TLC252CD at VDD = 5 V and TA = 25°C?
The unity-gain bandwidth of TLC252CD is 1.7 MHz under VDD = 5 V and TA = 25°C conditions, as measured with VI = 10 mV, CL = 20 pF, and shown in the "Operating Characteristics, VDD = 5 V" table on page 8 of the datasheet.
Is TLC252CD pin-compatible with other variants like TLC252ACD or TLC252BCD?
Yes, TLC252CD is pin-compatible with TLC252ACD and TLC252BCD-all share identical SOIC-D packaging, pinout, and footprint. The suffix difference (C/A/B) denotes input offset voltage grade only (10 mV / 5 mV / 2 mV max), with no change to pin function or mechanical form factor.
What package options are available for TLC252CD beyond the standard D package?
The TLC252CD is exclusively offered in the 8-pin SOIC (D) package per the "Available Options" table. Other variants (e.g., TLC252CP, TLC252CPW) exist in PDIP and TSSOP packages-but TLC252CD itself is not manufactured in P or PW packages. Tape-and-reel delivery is supported via suffix R (TLC252CDR).
