Product details
Overview
TLC272CPS from Texas Instruments is a precision dual CMOS operational amplifier optimized for single-supply operation, featuring 10 mV input offset voltage (max), 0.5 V/μs slew rate, and rail-to-rail output swing down to the negative rail - enabling accurate signal conditioning in battery-powered sensor interfaces and industrial analog front-ends.
For engineers reviewing the TLC272CPS datasheet, TLC272CPS pinout, TLC272CPS application, or TLC272CPS equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative options - all grounded in TI's SLOS091F production data sheet (Rev. F, Jan 2026).
Technical Context
The TLC272CPS uses a polysilicon-gate CMOS process to achieve ultra-high input impedance (>10¹² Ω), low input bias current (10–60 pA typ), and low noise (10.8 nV/√Hz at 1 kHz). Its input stage supports common-mode voltage down to –0.1 V (at VDD = 5 V), enabling true single-supply operation with ground-referenced inputs.
It delivers 4.5 MHz unity-gain bandwidth and 60° phase margin with 20 pF load, ensuring stable closed-loop performance in transimpedance amplifiers and active filters. The device is rated for 0°C to 70°C operation and specified across 3 V to 16 V supply range - matching TTL/HCMOS logic rails while preserving dynamic range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 10 mV max at 25°C - sets DC accuracy limit in precision gain stages and sensor amplification |
| Slew Rate | 0.5 V/μs - supports <10 kHz full-power bandwidth for 1 Vpp signals in low-noise instrumentation |
| Supply Voltage Range | 3 V to 16 V - enables direct interface with 3.3 V, 5 V, and 12 V systems without level-shifting |
| Input Bias Current | 10–60 pA typical - allows >1 MΩ source impedances without significant DC error in pH or photodiode circuits |
| Common-Mode Input Range | Extends to –0.1 V below negative rail - permits ground-referenced input in single-supply configurations |
| Output Voltage Swing | Reaches negative rail (0 V) with 10 kΩ load - eliminates need for negative supply in level-shifting or comparator reference circuits |
| Equivalent Input Noise | 10.8 nV/√Hz at 1 kHz - suitable for low-frequency sensor amplification where thermal noise dominates |
Pinout & Package
The TLC272CPS is supplied in an 8-pin SOP (Small Outline Package) with 6.2 mm × 7.8 mm footprint and standard 1.27 mm pitch - compatible with automated PCB assembly and space-constrained industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier A) | High-impedance node accepting differential signal; requires guard ring if high-Z sources used |
| 2 | Non-Inverting Input (Amplifier A) | Accepts reference or sensor signal; common-mode range includes ground for single-supply biasing |
| 3 | Output (Amplifier A) | Capable of sourcing/sinking ±30 mA; swings to negative rail under light load |
| 4 | Negative Supply (V–) | Typically connected to GND in single-supply mode; must be bypassed with 0.1 μF ceramic capacitor |
| 5 | Non-Inverting Input (Amplifier B) | Independent second channel input; identical specs and layout rules as Pin 2 |
| 6 | Inverting Input (Amplifier B) | Matches Pin 1 functionality; supports dual-channel signal processing on one die |
| 7 | Output (Amplifier B) | Electrically isolated from Output A; shares same supply pins and thermal characteristics |
| 8 | Positive Supply (V+) | Accepts 3–16 V; requires local decoupling to maintain PSRR >65 dB across frequency |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply optimized input stage | Common-mode range extends below negative rail (–0.1 V), enabling ground-referenced inputs without level shifters |
| Rail-to-rail output capability | Drives to negative rail (0 V) with 10 kΩ load - simplifies interfacing with ADCs and digital comparators |
| Ultra-low input bias current | 10–60 pA typical - preserves signal integrity with high-impedance sensors (e.g., piezoelectric, pH electrodes) |
| Low 1/f noise corner | 10.8 nV/√Hz at 1 kHz - outperforms bipolar op-amps above 50 kΩ source impedance in precision measurement |
| ESD protection circuitry | Integrated protection per JEDEC JS-001 - withstands ≥2 kV HBM, reducing board-level ESD design overhead |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV272IDR | Lower VIO (2 mV max), higher quiescent current (1.25 mA vs 3.2 mA), same SOP-8 package | Better DC accuracy but higher power draw - preferred in low-drift, moderate-speed applications | Select TLV272IDR when VIO < 2 mV is required and supply current budget allows +0.2 mA per amplifier |
| OPA2333AIDR | Zero-drift architecture, 12 µV max VIO, 17 µV/°C drift, 360 kHz GBW, higher cost | Superior long-term stability and temperature drift - suited for metrology-grade calibration systems | Choose OPA2333AIDR only when sub-20 µV total drift over temperature is mandatory and cost is secondary |

FAQ
What is the maximum supply voltage for the TLC272CPS?
The TLC272CPS has an absolute maximum supply voltage of 18 V, but its recommended operating range is 3 V to 16 V. Operating at 16 V maximizes dynamic range and output swing, while 3 V enables compatibility with low-voltage microcontrollers and battery-powered systems. Exceeding 16 V risks exceeding internal junction limits and degrading long-term reliability.
Does the TLC272CPS support true rail-to-rail input?
No - the TLC272CPS does not support rail-to-rail input. Its common-mode input voltage range extends to –0.1 V below the negative rail (enabling ground-referenced inputs), but the upper limit is VDD – 1 V at 25°C and VDD – 1.5 V over full temperature range. This means it cannot accept signals at the positive rail without external attenuation or level shifting.
Can unused channels of the TLC272CPS be left floating?
No - unused amplifiers in the TLC272CPS must not be left floating. TI explicitly recommends configuring them as grounded unity-gain followers (non-inverting input tied to GND, output connected to inverting input) to prevent oscillation, excessive current draw, or unpredictable output states that could couple noise into adjacent channels.
What is the typical input bias current of the TLC272CPS at 70°C?
At 70°C, the TLC272CPS exhibits a typical input bias current of 40–600 pA, depending on unit variation and test conditions. The datasheet specifies 40 pA typical and 600 pA maximum at 70°C for the C-suffix grade. This remains sufficiently low to avoid significant error with source impedances up to 100 kΩ in most industrial sensing applications.
Is the TLC272CPS RoHS compliant and lead-free?
Yes - the TLC272CPS (SOP-8 package) is RoHS compliant and lead-free, meeting EU Directive 2011/65/EU and TI's corporate environmental standards. The "PS" suffix denotes the lead-free, green (halogen-free) SOP packaging variant, with SnAgCu solder finish and compliant marking per J-STD-609.
