Product details
Overview
TLC272ACP from Texas Instruments is a precision dual CMOS operational amplifier in 8-pin PDIP package, delivering 10 mV max input offset voltage, 0.5 V/μs slew rate, and rail-to-rail output swing down to the negative rail - enabling accurate signal conditioning in single-supply sensor interfaces and industrial analog front-ends.
For engineers reviewing the TLC272ACP datasheet, TLC272ACP pinout, TLC272ACP application, or TLC272ACP equivalent, this page provides verified electrical parameters, validated pin functions, confirmed use cases in low-power instrumentation, and two technically documented alternative parts for design flexibility.
Technical Context
The TLC272ACP uses a polysilicon-gate CMOS process to achieve >10¹² Ω input impedance and <60 pA typical input bias current at 25°C, supporting high-impedance source interfacing without significant loading error. Its input common-mode range extends below ground (–0.1 V at VDD = 5 V), and output swings to within 50 mV of the negative rail under load.
Designed for single-supply operation from 3 V to 16 V (0°C to 70°C), it features low 10.8 nV/√Hz input voltage noise at 1 kHz and 4.5 MHz unity-gain bandwidth - balancing precision, speed, and power efficiency for cost-sensitive embedded measurement systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | 10 mV max at 25°C - enables DC-coupled amplification of mV-level sensor signals without nulling circuitry |
| Slew rate | 0.5 V/μs - supports stable amplification of ≤10 kHz full-scale step inputs with minimal distortion |
| Supply voltage range | 3 V to 16 V - compatible with 3.3 V, 5 V, and 12 V logic rails and battery-powered systems |
| Input impedance | >10¹² Ω - prevents loading of high-Z sources like piezoelectric sensors or pH electrodes |
| Output voltage swing | Within 50 mV of negative rail - allows true single-supply operation with ground-referenced inputs and outputs |
| Input voltage noise | 10.8 nV/√Hz at 1 kHz - lower than bipolar op-amps above 50 kΩ source impedances |
| Unity-gain bandwidth | 4.5 MHz - sufficient for anti-aliasing filters and active sensor signal conditioning stages |
Pinout & Package

| 3 | Non-inverting input A | High-impedance node; common-mode range extends to –0.1 V below V– at VDD = 5 V |
| 4 | V– (GND) | Negative supply terminal; serves as reference for single-supply operation and output swing |
| 5 | Non-inverting input B | Independent high-Z input for second amplifier; identical specs to Pin 3 |
| 6 | Inverting input B | Independent high-Z input for second amplifier; identical specs to Pin 2 |

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 |
|---|---|---|---|
| TLV272CP | Lower 3.5 mV max VIO, 1.8–16 V supply, 1.25 mA IDD - improved DC precision at slightly higher quiescent current | Better for <100 ppm accuracy requirements; less suitable for ultra-low-power designs | Select TLV272CP when VIO < 5 mV is mandatory and supply >3 V is guaranteed |
| LM358N | Bipolar input, 7 mV max VIO, 3–32 V supply, 0.7 mA IDD - wider voltage range but higher 20 nV/√Hz noise and 30 pA IB | Preferred for high-voltage industrial controls; unsuitable for high-Z sensor buffering | Choose LM358N only for legacy compatibility or >16 V operation; avoid for precision low-noise designs |
Compared with TLV272CP and LM358N, the TLC272ACP delivers optimal balance of low-cost precision, single-supply usability, and proven reliability in temperature-stable instrumentation - making it ideal for mid-tier industrial and test equipment where 10 mV VIO and 3 V operation are sufficient.

FAQ
What is the maximum operating temperature range for the TLC272ACP?
The TLC272ACP is rated for 0°C to 70°C operation (C-suffix grade). It supports supply voltages from 3 V to 16 V across this range, with input common-mode voltage extending to –0.1 V below ground at 25°C. Full electrical specifications are guaranteed within this ambient temperature window, and thermal derating is not required up to 70°C.
Does the TLC272ACP support true rail-to-rail input operation?
No - the TLC272ACP features rail-to-rail *output* swing (to within 50 mV of V–), but its input common-mode range extends only to –0.1 V below V– and up to VDD – 1 V at 25°C. It does not accept inputs beyond these limits. For true rail-to-rail input capability, consider TI's TLV272 or OPA2313 families.
Can the TLC272ACP be used with a 3.3 V supply?
Yes - the TLC272ACP is fully specified down to 3 V supply at 0°C to 70°C. At VDD = 3.3 V, it maintains >10¹² Ω input impedance, 10 mV max VIO, and output swing to within 50 mV of ground. Performance metrics such as slew rate (0.5 V/μs) and bandwidth (4.5 MHz) remain valid, making it suitable for 3.3 V microcontroller-based sensor nodes.
How does the input bias current of the TLC272ACP affect high-impedance sensor circuits?
The TLC272ACP's typical input bias current is ≤60 pA at 25°C, resulting in <60 µV error across a 1 MΩ source impedance. This enables direct connection to pH electrodes, photodiode transimpedance feedback networks, and piezoelectric sensors without guard rings or active bias cancellation - provided PCB contamination and socket leakage are controlled.
Is the TLC272ACP pin-compatible with the LM358N in PDIP-8 packages?
Yes - the TLC272ACP and LM358N share identical PDIP-8 pinouts (dual op-amp configuration with V+, Output A, In– A, In+ A, In+ B, In– B, Output B, V–). However, the TLC272ACP offers superior DC specs (lower VIO, higher Zin, better PSRR) and requires no layout changes for drop-in replacement in most 5 V or 12 V systems.
