Product details
Overview
TLC25L2CD from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for ultra-low-power, single-supply operation down to 1.4 V, featuring 10 mV max input offset voltage (VIO), 20–34 µA typical supply current (IDD) 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 TLC25L2CD datasheet, TLC25L2CD pinout, TLC25L2CD application, or TLC25L2CD equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative options - all grounded in the official SLOS002I datasheet (Rev. March 2001).
Technical Context
The TLC25L2CD implements a silicon-gate LinCMOS™ process, enabling extremely high input impedance (>10¹² Ω), sub-1 pA input bias current, and stable VIO across temperature. Its architecture supports true single-supply operation with common-mode input range including GND and output swing near both rails under light loads.
It is internally compensated for unity-gain stability and exhibits low-noise performance (68 nV/√Hz at 1 kHz) with bandwidth-limited slew rate (0.03 V/µs typ at 5 V), making it suitable for DC-coupled, low-frequency precision amplification rather than high-speed signal processing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIO max | 10 mV at 25°C - defines worst-case DC error in precision gain stages without trimming |
| Supply voltage range | 1.4 V to 16 V - enables direct operation from single alkaline, NiMH, or Li-ion cells |
| IDD (two amps) | 20–34 µA typ at 5 V - supports multi-year battery life in always-on monitoring systems |
| Input bias current | ≤60 pA max - preserves signal integrity in high-impedance pH, photodiode, or piezoelectric sensor circuits |
| Common-mode range | Includes VDD–/GND - allows direct interfacing to ground-referenced transducers without level-shifting |
| Unity-gain bandwidth | 85–100 MHz typ at 5 V - sufficient for anti-aliasing, active filtering, and sensor buffering up to ~100 kHz |
| CMRR | 65–94 dB - rejects power-supply and shared-ground noise in mixed-signal embedded systems |
Pinout & Package
Package: 8-pin SOIC (D package), surface-mount, tape-and-reel compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives low-capacitance loads (≤100 pF) directly; limited drive strength due to low IDD |
| 2 | IN− A | Inverting input of Amp A - high-impedance node; sensitive to PCB leakage and ESD |
| 3 | IN+ A | Non-inverting input of Amp A - accepts signals from 0 V to VDD − 0.2 V with minimal error |
| 4 | VDD–/GND | Ground reference for both amplifiers - must be low-impedance; shared return path affects CMRR |
| 5 | VDD | Positive supply - decoupling capacitor (0.1 µF) required within 5 mm for stability |
| 6 | OUT B | Amplifier B output - independent channel; identical specs to OUT A |
| 7 | IN− B | Inverting input of Amp B - electrically isolated from Amp A inputs but shares supply rails |
| 8 | IN+ B | Non-inverting input of Amp B - enables dual-channel signal conditioning on one die |
Key Features
| Feature | Design Value |
|---|---|
| True single-supply operation | Operates from 1.4 V with input range including GND - eliminates need for split supplies in portable designs |
| Ultra-low quiescent current | 20–34 µA total for two op-amps - extends battery runtime in IoT endpoints and wearables |
| High input impedance | >10¹² Ω - prevents loading of high-Z sources like thermistors, capacitive sensors, or electrochemical cells |
| ESD protection | 2000 V HBM per MIL-STD-883C - reduces handling risk during assembly and field service |
| Stable over temperature | VIO drift ≤1.1 µV/°C - maintains calibration integrity across 0°C to 70°C industrial range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27L2CD | Same LinCMOS™ process, 2-mV VIO max, 2× higher IDD (45 µA typ) | Better DC accuracy but higher power - suitable where VIO < 2 mV is mandatory | Select when tighter offset spec justifies 2× current increase |
| LPV521DRX | CMOS input, 1.5-µA IDD, 1.5-mV VIO, 3.6-V min supply | Lower power and better VIO, but incompatible with 1.4–3.3 V battery ranges | Prefer for new designs targeting <2 µA total system sleep current |
Compared with TLC25L2CD, TLC27L2CD trades higher supply current for lower VIO, while LPV521DRX achieves lower power and offset but requires ≥3.6 V supply - making TLC25L2CD uniquely suited for sub-3 V, moderate-accuracy, long-life applications.

FAQ
What is the minimum operating voltage for the TLC25L2CD?
The TLC25L2CD operates down to 1.4 V, enabling direct use with single-cell alkaline, NiMH, or lithium primary batteries. This specification is confirmed in the "Recommended Operating Conditions" table of the SLOS002I datasheet, where VDD(min) = 1.4 V across 0°C to 70°C ambient.
Does the TLC25L2CD support rail-to-rail input?
Yes - the TLC25L2CD features a common-mode input voltage range that includes the negative rail (VDD–/GND), allowing inputs to swing from 0 V up to VDD − 0.2 V at 5 V supply. This is explicitly stated in the "Recommended Operating Conditions" and verified in electrical characteristics tables for VICR.
What is the typical supply current of the TLC25L2CD at 5 V?
At VDD = 5 V and TA = 25°C, the TLC25L2CD draws 20–34 µA total for both amplifiers, as specified in the "Electrical Characteristics" table on page 9 of SLOS002I. This ultra-low IDD enables multi-year operation in always-on sensor nodes.
Is the TLC25L2CD pin-compatible with other devices in the TLC25x2 family?
Yes - all TLC25x2 variants (TLC252, TLC25L2, TLC25M2) share identical 8-pin D, P, and PW package footprints and pinouts. The TLC25L2CD uses the same SOIC-8 layout as TLC252CD and TLC25M2CD, enabling drop-in substitution where bandwidth and drive requirements align.
What is the maximum input offset voltage for the TLC25L2CD?
The TLC25L2CD has a maximum input offset voltage (VIO) of 10 mV at 25°C, as defined in the "Available Options" table and confirmed in electrical characteristics on page 9 of the SLOS002I datasheet. This applies to the 'C' grade (0°C to 70°C) commercial temperature range.
