Product details
Overview
TLC25L2CP from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for ultra-low-power, single-supply operation down to 1.4 V. It delivers 2-mV max input offset voltage (B-grade), 20–46 µA total 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 TLC25L2CP datasheet, TLC25L2CP pinout, TLC25L2CP application, or TLC25L2CP equivalent, key selection criteria include its 2-mV VIO grade, 68 nV/√Hz input noise at 1 kHz, unity-gain bandwidth of 85–100 kHz (VDD = 5 V), and compatibility with 1-MΩ high-impedance feedback networks in transducer amplification stages.
Technical Context
The TLC25L2CP uses Texas Instruments' silicon-gate LinCMOS™ process to achieve femtoamp-level input bias currents (<60 pA) and stable DC performance across 0°C to 70°C. Its input stage supports true single-supply operation with VICR including GND, while internal ESD protection meets MIL-STD-883C, Method 3015.1 (2000 V).
It is internally compensated for unity-gain stability and exhibits phase margins of 34°–40° at 5 V, supporting robust closed-loop designs in active filters and precision buffers without external compensation components.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462CP | Higher supply current (550 µA), lower VIO (0.6 mV), rail-to-rail output only (not input) | Requires level-shifting for ground-referenced inputs; unsuitable for sub-2-V operation | Select when higher speed (6.4 MHz GBW) and tighter VIO are prioritized over battery life |
| LPV521MG/NOPB | Lower supply current (320 nA), higher VIO (1.25 mV), single-channel only | Requires two devices for dual functionality; lacks integrated dual layout and matching | Select for ultra-long-life (>10-year) applications where dual-channel integration is not mandatory |

FAQ
What is the maximum input offset voltage specification for the TLC25L2CP?
The TLC25L2CP is the B-grade variant of the TLC25L2 series and is specified with a maximum input offset voltage of 2 mV at 25°C and 3 mV across the full 0°C to 70°C operating temperature range. This guaranteed VIO enables predictable DC accuracy in uncalibrated, low-cost sensor signal chains without trimming components.
Does the TLC25L2CP support true single-supply operation with input signals referenced to ground?
Yes, the TLC25L2CP supports true single-supply operation with its common-mode input voltage range explicitly including the negative rail (VDD–/GND). At VDD = 5 V, the input range extends from –0.2 V to +3.5 V, allowing direct connection of ground-referenced transducers such as thermistors or bridge sensors without external level-shifting circuitry.
What is the typical supply current consumption of the TLC25L2CP at 5 V?
The TLC25L2CP draws 20–34 µA total supply current (both amplifiers) at VDD = 5 V and TA = 25°C, rising to 28 µA at 70°C. This ultra-low IDD enables multi-year operation from standard coin cells and makes the device ideal for always-on sensing applications where power budget is constrained to single-digit microamps.
Can the TLC25L2CP drive a 1-MΩ load while maintaining DC accuracy?
Yes, the TLC25L2CP is characterized with RL = 1 MΩ in its electrical specifications, including parameters like AVD (large-signal voltage gain), CMRR, and kSVR. Its LinCMOS™ input stage ensures <60 pA input bias current, minimizing voltage error across high-value feedback or source impedances - critical for maintaining DC accuracy in precision transducer interfaces.
Is the TLC25L2CP pin-compatible with other devices in the TLC25x2 family?
Yes, the TLC25L2CP shares identical 8-pin DIP (P) package pinout and footprint with all members of the TLC25x2 family, including TLC252CP, TLC25M2CP, and their A/B-suffix variants. This allows direct substitution within the same family for trade-offs in bandwidth, supply current, or offset voltage - provided PCB layout accommodates thermal and noise requirements of the selected grade.
