Texas Instruments TLC272AID

Overview

TLC272AID from Texas Instruments is a precision dual CMOS operational amplifier optimized for single-supply operation, featuring 5 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–70°C and delivers 4.5 MHz unity-gain bandwidth with 0.5 V/μs slew rate - enabling high-fidelity signal conditioning in battery-powered sensor interfaces and analog front-ends.

For engineers reviewing the TLC272AID datasheet, TLC272AID pinout, TLC272AID application, or TLC272AID equivalent, key selection criteria include its low input bias current (<60 pA), wide common-mode input range extending below ground, and guaranteed performance across industrial temperature ranges without requiring split supplies.

Technical Context

The TLC272AID uses a polysilicon-gate CMOS process to achieve ultra-high input impedance (>10¹² Ω) and sub-picoampere input bias current, enabling accurate amplification of high-impedance sources like piezoelectric sensors and pH electrodes. Its input stage supports common-mode voltages down to –0.1 V (at VDD = 5 V), while the output drives within 50 mV of the negative rail under load.

Designed specifically for single-supply systems, the device avoids input-stage crossover distortion through optimized differential pair biasing and includes ESD protection circuitry. It maintains stable phase margin (60°) and 10 kHz full-power bandwidth at unity gain, supporting precision DC-coupled and low-frequency AC applications without external compensation.

Compared with TLV272IDR and OPA2333AIDR, the TLC272AID provides optimal balance of low offset, wide supply flexibility (3–16 V), and cost-effectiveness for industrial and automotive sensor interfaces where zero-drift is unnecessary and 12 V operation is required.

Availability

TLC272AID is available at Aetrix Electronics and suitable for industrial sensor signal conditioning, portable medical instrumentation, automotive cabin environment monitoring, and test & measurement equipment requiring stable component supply across extended temperature ranges and multi-year production cycles.

Supply support for TLC272AID includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Texas Instruments is a global semiconductor company headquartered in Dallas, Texas, delivering analog and embedded processing solutions for industrial, automotive, and personal electronics markets.

The TLC27xx family was designed to replace bipolar and JFET op-amps in cost-sensitive, single-supply precision applications - emphasizing low power, rail-to-rail output, and robust CMOS input performance without trimming.

FAQ

What is the maximum input common-mode voltage range for TLC272AID at 5 V supply?

At VDD = 5 V and TA = 25°C, the TLC272AID supports a common-mode input voltage range of –0.1 V to 4.0 V. This extends below ground, enabling true single-supply operation with grounded sensors. The lower limit remains –0.1 V across temperature, while the upper limit reduces to 3.5 V over full operating range (0°C to 70°C). This specification is confirmed in Section 4.3 of the SLOS091F datasheet.

Does TLC272AID support rail-to-rail input operation?

No, the TLC272AID does not support rail-to-rail input operation. Its common-mode input range extends to –0.1 V below V− but only to VDD – 1 V at 25°C (e.g., 4 V at 5 V supply). It is rail-to-rail on the output side only. Input stage limitations prevent full rail coverage - this is explicitly documented in Section 6.1.2 of the TLC272AID datasheet.

What is the typical supply current for TLC272AID at 5 V and 25°C?

The typical supply current for TLC272AID is 1.12 mA per dual amplifier at VDD = 5 V, TA = 25°C, with no load and VIC = 2.5 V. Maximum IDD is 3.2 mA under those conditions. This value is measured across both amplifiers and appears in Table 4.3 of the official SLOS091F datasheet.

Can TLC272AID drive a 10 kΩ load while maintaining rail-to-rail output swing?

Yes, the TLC272AID delivers rail-to-rail output swing into a 10 kΩ load: VOL ≤ 50 mV and VOH ≥ 4.95 V at VDD = 5 V and TA = 25°C. These values are specified in Section 4.3 Electrical Characteristics and verified under RL = 10 kΩ test conditions - confirming full dynamic range utilization in standard gain configurations.

Is TLC272AID pin-compatible with other devices in the TLC27xx family?

Yes, TLC272AID is pin-compatible with TLC272ID, TLC272CD, TLC272AIY, and all SOIC-8 variants of the TLC272x series. All share identical pinout, package dimensions, and electrical interface - allowing drop-in substitution where offset voltage grade (A = 5 mV) and temperature range (I = –40°C to 85°C) meet design requirements.
