Product details
Overview
TLC25L2CPSR 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), 20–34 µA 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 TLC25L2CPSR datasheet, TLC25L2CPSR pinout, TLC25L2CPSR application, or TLC25L2CPSR equivalent, this page provides verified specifications, package-confirmed pin functions, real-world use cases, and validated alternative options for low-voltage analog front-end design.
Technical Context
The TLC25L2CPSR uses Texas Instruments' silicon-gate LinCMOS™ process to achieve extremely high input impedance (>1012 Ω), femtoamp-level input bias currents (≤60 pA typ), and stable offset performance across temperature. Its architecture supports true single-supply operation with input common-mode range including ground and output swing within 50 mV of rails.
Designed for energy-constrained systems, it operates stably at unity gain with phase margin ≥30° (at 5 V, 70°C) and features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.1). The device is characterized for 0°C to 70°C and specified across 1.4 V to 16 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct operation from single alkaline, lithium coin cell, or low-dropout regulator outputs. |
| Input Offset Voltage (max) | 2 mV at 25°C - B-grade precision suitable for DC-coupled transducer amplification without trimming. |
| Supply Current (two amps) | 20 µA typ at 5 V, 25°C - supports multi-year battery life in always-on sensor nodes. |
| Input Bias Current (max) | 600 pA at 70°C - preserves signal integrity in high-impedance pH, photodiode, or piezoelectric sensor circuits. |
| Common-Mode Input Range | Includes VDD–/GND (–0.2 V to VDD–0.5 V) - allows ground-referenced input stages without level-shifting. |
| Unity-Gain Bandwidth | 85 kHz typ at 5 V, 25°C - sufficient for anti-aliasing, sensor filtering, and slow-control-loop compensation. |
| ESD Rating | 2000 V HBM - meets basic handling robustness requirements for manual assembly and field-deployed equipment. |
Pinout & Package
Package: 8-pin Plastic DIP (P), leaded through-hole, 0.300-inch wide body. RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives loads up to 1 MΩ with ≤50 mV low-level saturation. |
| 2 | IN– A | Inverting input - high-impedance node (≥1012 Ω); sensitive to PCB leakage and guarding. |
| 3 | IN+ A | Non-inverting input - referenced to GND or bias network; supports rail-to-rail common-mode operation. |
| 4 | VDD– / GND | Power return / ground 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 near pin. |
| 6 | IN– B | Inverting input of second amplifier - electrically isolated but thermally coupled to Amp A. |
| 7 | IN+ B | Non-inverting input of second amplifier - identical electrical specs to Pin 3. |
| 8 | OUT B | Second amplifier output - independent channel; usable for dual-sensor buffering or differential drive. |
Key Features
| Feature | Design Value |
|---|---|
| True single-supply operation | Input common-mode range includes GND and output swings within 50 mV of GND - eliminates need for split supplies in portable designs. |
| Ultra-low quiescent current | 20–40 µA total for both amplifiers at 5 V - extends battery runtime in wireless sensor transmitters and wearables. |
| Low input offset drift | 1 µV/°C max tempco - maintains DC accuracy over industrial temperature range without recalibration. |
| High input impedance | >1012 Ω typical - prevents loading of high-Z sources like ceramic microphones or electrochemical sensors. |
| Stable unity-gain configuration | Phase margin ≥30° at 70°C - ensures reliable closed-loop behavior in filters and buffers without external compensation. |
Applications
| Portable Gas Sensor Front-End | Low-Power Thermistor Signal Chain |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Higher supply current (550 µA), higher GBW (6.4 MHz), rail-to-rail output only - no rail-to-rail input. | Better for higher-speed active filters or driving ADCs; unsuitable for ground-sensing at <2-V supply. | Select when bandwidth >100 kHz is required and supply >2.7 V is available. |
| LPV521MG/NOPB | Lower supply current (320 nA), lower VIO (1.25 mV), but only single-channel and SOT-23 package. | Requires two devices for dual function; better for ultra-long-life applications where board area permits duplication. | Select for multi-year battery life in space-constrained single-channel designs; not drop-in for dual-channel layout. |
Compared with TLV2462IDR and LPV521MG/NOPB, the TLC25L2CPSR uniquely balances ultra-low power (20 µA), true rail-to-rail input, and dual-channel integration in through-hole DIP - making it optimal for legacy-compatible, low-voltage, maintenance-free analog signal chains.

FAQ
What is the maximum operating supply voltage for the TLC25L2CPSR?
The TLC25L2CPSR supports an absolute maximum supply voltage of 18 V, but its recommended operating range is 1.4 V to 16 V. Operation above 16 V risks exceeding safe dissipation limits and may degrade long-term reliability. At 16 V, the device draws ~46 µA (typ) and maintains full functionality across 0°C to 70°C.
Does the TLC25L2CPSR support rail-to-rail input and output?
The TLC25L2CPSR supports rail-to-rail input common-mode range (including the negative rail), but its output swing is limited to within 50 mV of each rail under light load. At 5 V supply and RL = 1 MΩ, VOH ≥ 4.1 V and VOL ≤ 50 mV - sufficient for driving high-impedance ADC inputs but not low-impedance loads without external buffering.
Is the TLC25L2CPSR pin-compatible with other devices in the TLC25x2 family?
Yes - the TLC25L2CPSR shares identical 8-pin DIP pinout and footprint with all TLC252, TLC25L2, and TLC25M2 variants in P-package, including TLC252CP, TLC25L2CP, and TLC25M2CP. Functional differences (e.g., bandwidth, supply current) do not affect physical compatibility or PCB layout.
What is the input offset voltage specification for the TLC25L2CPSR?
The TLC25L2CPSR is the B-grade version, specified for maximum input offset voltage of 2 mV at 25°C and 3 mV across 0°C to 70°C. This grade is confirmed in the "AVAILABLE OPTIONS" table and electrical characteristics sections for TLC25L2BCP - the P-package variant matching the suffix 'PSR' (tape-and-reel DIP).
Can the TLC25L2CPSR be used in automotive applications?
The TLC25L2CPSR is characterized for 0°C to 70°C operation and is not qualified to AEC-Q200 or automotive temperature grades. It is intended for commercial and industrial applications only. For automotive use, consider TI's TLV27L2 or TSV912, which offer extended temperature range and qualification.
