Product details
Overview
TLC272BCPG4 from Texas Instruments is a precision dual CMOS operational amplifier optimized for single-supply operation, featuring 2 mV max input offset voltage (25°C), 10.8 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing down to the negative rail. It operates from 3 V to 16 V over 0°C to 70°C and delivers 0.5 V/μs slew rate and 4.5 MHz unity-gain bandwidth - enabling accurate low-level signal conditioning in battery-powered sensor interfaces.
For engineers reviewing the TLC272BCPG4 datasheet, TLC272BCPG4 pinout, TLC272BCPG4 application, or TLC272BCPG4 equivalent, key selection criteria include its guaranteed 2 mV VIO grade, C-suffix temperature range (0°C to 70°C), PDIP-8 package with through-hole mounting, and compatibility with single-supply systems requiring high input impedance (>1012 Ω) and low bias current (≤60 pA).
Technical Context
The TLC272BCPG4 uses a polysilicon-gate CMOS process to achieve ultra-low input bias current and stable offset voltage drift (0.3 μV/°C). Its input stage supports common-mode voltage down to the negative rail, and its output stage drives to within 50 mV of ground under load - critical for single-supply transducer amplification.
It integrates ESD protection circuitry and latch-up immunity, and is characterized across supply voltages (3–16 V) and temperatures (0°C to 70°C) with full electrical specifications including CMRR ≥65 dB, PSRR ≥65 dB, and open-loop gain ≥5 V/mV - ensuring robust performance in noisy industrial analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | Max 2 mV at 25°C - enables DC-coupled amplification of sub-10 mV sensor signals without nulling circuitry |
| Input Voltage Noise | 10.8 nV/√Hz at 1 kHz - supports low-noise amplification of high-impedance sources (e.g., piezoelectric sensors) |
| Slew Rate | 0.5 V/μs - sufficient for <10 kHz full-power bandwidth in unity-gain buffer configurations |
| Unity-Gain Bandwidth | 4.5 MHz - allows stable closed-loop gain ≥10 up to ~450 kHz with adequate phase margin (60°) |
| Common-Mode Input Range | Extends to negative rail - permits direct interfacing with ground-referenced sensors in single-supply systems |
| Supply Voltage Range | 3 V to 16 V - compatible with 3.3 V, 5 V, and 12 V rails without level-shifting components |

| 3 | Non-Inverting Input A | High-impedance node; common-mode range includes GND - enables single-supply reference biasing |
| 4 | GND | Power and signal reference plane - must be low-impedance for noise rejection and stability |
| 5 | Non-Inverting Input B | Independent high-Z input for second channel; identical specs to Pin 3 |
| 6 | Inverting Input B | Independent high-Z input for second channel; identical specs to Pin 2 |
| 7 | Output B | Amplifier B output - electrically isolated from Output A; same drive capability and swing limits |
| 8 | VDD | Positive supply rail - accepts 3 V to 16 V; requires local 0.1 μF ceramic bypass to GND |
Key Features

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 |
|---|---|---|---|
| TLV272IP | Lower VIO (1.5 mV max), lower supply current (1.25 mA typ), but narrower supply range (2.7–16 V) and no 0°C–70°C guarantee for VIO | Better for ultra-low-power portable designs; less suitable for industrial temp-range-critical calibration | Choose TLV272IP if supply current <1.3 mA is mandatory and VIO spec at 70°C is not required |
| OPA2333PA | Zero-drift architecture, 2 μV max VIO, 0.02 μV/°C drift, but higher cost and 1.8–5.5 V supply limit | Required for sub-μV DC stability in lab-grade instruments; incompatible with 12 V or 16 V supplies | Choose OPA2333PA only when nanovolt-level long-term DC accuracy outweighs supply flexibility and cost |
Compared with TLV272IP and OPA2333PA, the TLC272BCPG4 provides the optimal balance of guaranteed 2 mV VIO over 0°C–70°C, 3–16 V operation, and PDIP-8 through-hole compatibility - making it ideal for cost-sensitive industrial and automotive analog signal chains where wide supply range and proven reliability are essential.

FAQ
What is the maximum input offset voltage specification for TLC272BCPG4 across its operating temperature range?
The TLC272BCPG4 has a maximum input offset voltage of 2 mV at 25°C and 3 mV over the full 0°C to 70°C operating range. This is explicitly specified in the Electrical Characteristics tables for TLC272BC-grade devices under both VDD = 5 V and VDD = 10 V conditions, confirming its suitability for precision DC-coupled amplification without trimming.
Does TLC272BCPG4 support true single-supply operation with input signals referenced to ground?
Yes, the TLC272BCPG4 supports true single-supply operation: its common-mode input voltage range extends to the negative rail (GND), and its output swings to within 50 mV of GND. This allows direct connection of ground-referenced sensors - such as thermistors or bridge transducers - without level-shifting circuitry, as confirmed in Section 6.1.1 of the datasheet.
What package type and mounting style does TLC272BCPG4 use?
The TLC272BCPG4 uses an 8-pin PDIP (Plastic Dual In-line Package) with through-hole mounting. Its dimensions are 9.81 mm × 9.43 mm, and it features RoHS-compliant lead finish. This package is explicitly listed in the Device Information table for TLC272B variants and is designated by the "PG4" suffix per TI's packaging nomenclature.
How does the input bias current of TLC272BCPG4 impact high-impedance sensor interfaces?
The TLC272BCPG4 has a maximum input bias current of 60 pA at 70°C, enabling accurate amplification of signals from high-impedance sources like pH electrodes or photodiodes. At 25°C, typical IIB is ≤10 pA - low enough to avoid significant voltage error across 10 MΩ source impedances (<60 μV), preserving measurement integrity in precision analog front-ends.
Can TLC272BCPG4 be used in battery-powered applications with 3.3 V supply?
Yes, the TLC272BCPG4 is fully specified for operation down to 3 V supply voltage across 0°C to 70°C, making it compatible with standard 3.3 V Li-ion or alkaline battery systems. Its rail-to-rail output swing and ground-sensing input allow >3 Vpp signal headroom - verified in Recommended Operating Conditions (Section 4.2) and Electrical Characteristics (Sections 4.3–4.6).
