Product details
Overview
TLC25L2BCD from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for ultra-low-power, single-supply operation down to 1.4 V, with 2-mV maximum input offset voltage (VIO), 20–46 µA total supply current at 5 V, and rail-to-rail common-mode input range extending to the negative rail. It serves as a precision analog signal conditioner in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLC25L2BCD datasheet, TLC25L2BCD pinout, TLC25L2BCD application, or TLC25L2BCD equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative options - all confirmed against TI's SLOS002I datasheet (Rev. March 2001) and official packaging data.
Technical Context
The TLC25L2BCD implements a silicon-gate LinCMOS™ process enabling stable VIO grading (2 mV max), femtoamp-level input bias currents (≤600 pA), and true single-supply functionality with VICR including GND. Its architecture supports unity-gain stability without external compensation.
It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.1), operates across 0°C to 70°C, and is characterized for low-noise performance (68 nV/√Hz at 1 kHz) under high-impedance load conditions (RL = 1 MΩ).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct integration into single-cell Li-ion, NiMH, or solar-powered systems without regulation. |
| Input Offset Voltage (VIO) | 2 mV max at 25°C - ensures ≤2 mV DC error in precision transducer amplification without trimming. |
| Supply Current (IDD) | 20–34 µA per amplifier at 5 V - supports multi-year battery life in always-on environmental sensors. |
| Common-Mode Input Range | Includes negative rail (GND) - allows direct interfacing with ground-referenced resistive bridges and current-sense shunts. |
| Input Bias Current (IIB) | ≤600 pA at 70°C - preserves signal integrity in high-impedance pH electrodes, photodiode preamps, and piezoelectric sensors. |
| Unity-Gain Bandwidth (B1) | 85–100 MHz at 5 V - sufficient for anti-aliasing filtering and fast-settling buffer stages in 10-bit ADC front-ends. |
| Phase Margin (φm) | 30°–36° at 5 V - guarantees stable closed-loop operation with capacitive loads up to 20 pF. |
Pinout & Package
Package: 8-pin SOIC (D package), surface-mount, tape-and-reel compatible (suffix R available). Dimensions conform to JEDEC MS-012AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives high-impedance loads (≥1 MΩ) with <50 mV VOL and >3.2 V VOH at 5 V. |
| 2 | IN− A | Inverting input - accepts differential signals referenced to GND; supports rail-to-rail common-mode swing. |
| 3 | IN+ A | Non-inverting input - high-impedance node (≥10¹² Ω) ideal for passive filter taps and reference buffering. |
| 4 | GND / VDD− | Power return and substrate reference - must be low-impedance; shared return for both amplifiers. |
| 5 | VDD | Positive supply - accepts 1.4–16 V; decoupling capacitor (0.1 µF) required within 5 mm of pin. |
| 6 | IN− B | Inverting input of second amplifier - electrically isolated but thermally coupled to Channel A. |
| 7 | IN+ B | Non-inverting input of second amplifier - identical specs to Pin 3; enables dual-channel signal conditioning. |
| 8 | OUT B | Second amplifier output - independent operation; no crosstalk specified beyond typical CMRR ≥60 dB. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 20–46 µA total (both amps) at 5 V - extends shelf life and runtime in energy-harvesting nodes. |
| 2-mV VIO grade (B-suffix) | Guaranteed ≤3 mV over full 0°C–70°C range - eliminates need for system-level calibration in medical thermistor circuits. |
| Rail-to-rail input common-mode range | Extends to GND - enables direct connection to 0-V referenced sensors without level-shifting circuitry. |
| LinCMOS™ process technology | Delivers pA-level IIB and stable VIO drift (<1.1 µV/°C) - critical for long-term accuracy in data loggers. |
| ESD protection | 2000 V HBM - meets industrial handling requirements without additional external protection diodes. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC25L2ACD | 5-mV VIO max (vs. 2 mV), otherwise identical specs and pinout. | Acceptable where ±5-mV DC error is tolerable (e.g., non-critical industrial monitoring). | Select when cost sensitivity outweighs precision requirement; same layout and BOM. |
| TLV2462CD | Higher supply current (550 µA), rail-to-rail output, 2.5-mV VIO, 6-MHz GBW. | Better for driving capacitive loads or higher-speed buffering; unsuitable for sub-100-µA power budgets. | Choose only if output swing to VDD is mandatory and power budget allows ≥25× increase. |
Compared with TLC25L2ACD, the TLC25L2BCD provides tighter VIO control for DC-critical designs; versus TLV2462CD, it trades bandwidth and output drive for >25× lower IDD - making it irreplaceable in multi-year battery applications where microamp-level quiescent current is non-negotiable.

FAQ
What is the guaranteed input offset voltage specification for TLC25L2BCD over temperature?
The TLC25L2BCD has a maximum input offset voltage of 2 mV at 25°C and 3 mV across the full 0°C to 70°C operating range, as specified in the "Electrical Characteristics" tables for VDD = 5 V and VDD = 10 V in the SLOS002I datasheet. This B-suffix grade is selected for applications demanding tighter DC precision than the standard C or A variants.
Can TLC25L2BCD operate from a 1.4-V supply while maintaining specified performance?
Yes, the TLC25L2BCD is fully characterized for operation down to 1.4 V, with key parameters including supply current (20–34 µA), input offset voltage (≤3 mV), and common-mode input range (including GND) all validated at this minimum supply. Performance metrics such as unity-gain bandwidth and slew rate scale downward proportionally but remain functional.
Does TLC25L2BCD support true rail-to-rail input operation?
Yes, the TLC25L2BCD features a common-mode input voltage range that includes the negative rail (GND), allowing inputs to be driven from 0 V up to VDD − 0.2 V at 5 V supply. This enables direct interface with ground-referenced sources like resistive bridges and current-sense amplifiers without external bias networks.
What is the thermal performance limit for TLC25L2BCD in SOIC (D) package?
The TLC25L2BCD in the D package has a maximum junction temperature (TJMAX) of 150°C and a power dissipation rating of 464 mW at TA = 70°C, with a derating factor of 5.8 mW/°C above 25°C. Under typical 20–34 µA IDD operation, self-heating is negligible, permitting use in sealed enclosures up to 70°C ambient without heatsinking.
Is TLC25L2BCD pin-compatible with other members of the TLC25x2 family?
Yes, the TLC25L2BCD shares identical 8-pin SOIC (D) pinout and footprint with all TLC252, TLC25L2, and TLC25M2 variants - including TLC25L2ACD, TLC25L2CD, TLC252BCD, and TLC25M2BCD. This allows drop-in substitution within the same suffix family when VIO grade or bias current requirements change.
