Product details
Overview
TLC272BIDR from Texas Instruments is a precision dual CMOS operational amplifier optimized for single-supply operation, featuring 2 mV maximum 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 4 V to 16 V over –40°C to 85°C and delivers 4.5 MHz unity-gain bandwidth with 0.5 V/μs slew rate - ideal for sensor signal conditioning in industrial data acquisition systems.
For engineers reviewing the TLC272BIDR datasheet, TLC272BIDR pinout, TLC272BIDR application, or TLC272BIDR equivalent, key selection criteria include its low-input-bias-current design (<60 pA typical), wide common-mode input range extending below ground, and SOIC-8 packaging suitable for space-constrained analog front-ends requiring stable DC precision.
Technical Context
The TLC272BIDR uses a polysilicon-gate CMOS process to achieve ultra-high input impedance (>10¹² Ω) and low input bias current, enabling high-impedance source interfacing without significant error. Its input stage supports common-mode voltages down to –0.1 V (at VDD = 5 V), and output swings to within 50 mV of the negative rail under load.
Designed specifically for single-supply systems, it eliminates need for split supplies while maintaining 65–85 dB CMRR and 65–120 dB supply-voltage rejection across temperature. The device exhibits 0.3 μV/°C input offset drift and is latch-up immune per design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 2000 μV max at 25°C - defines worst-case DC error in precision gain stages without trimming |
| Supply Voltage Range | 4 V to 16 V - supports direct interface with 5 V and 12 V industrial logic rails |
| Unity-Gain Bandwidth | 4.5 MHz - enables stable closed-loop operation up to ~100 kHz with moderate gain |
| Slew Rate | 0.5 V/μs - limits large-signal transient response; sufficient for <10 kHz full-scale step fidelity |
| Input Voltage Noise | 10.8 nV/√Hz at 1 kHz - dominates total noise in medium-impedance circuits (≤50 kΩ) |
| Common-Mode Input Range | –0.1 V to VDD – 1.5 V - allows ground-referenced inputs in single-supply configurations |
| Output Voltage Swing | Within 50 mV of negative rail - preserves dynamic range when driving ADC reference buffers |
Pinout & Package
Package: SOIC-8 (D package), 4.9 mm × 6.0 mm body, 1.27 mm pitch, gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier A) | High-impedance node accepting differential signal; requires guard ring for leakage-sensitive applications |
| 2 | Non-Inverting Input (Amplifier A) | Accepts reference or sensor signal; common-mode range extends below ground |
| 3 | Output (Amplifier A) | Rail-to-rail capable output; sinks up to 30 mA, sources up to 30 mA |
| 4 | Negative Supply (GND) | Reference return for both amplifiers; must be low-impedance for noise immunity |
| 5 | Non-Inverting Input (Amplifier B) | Independent second channel input; identical specs and layout symmetry to Pin 2 |
| 6 | Inverting Input (Amplifier B) | Second channel differential input; shares same ESD protection and bias structure as Pin 1 |
| 7 | Output (Amplifier B) | Second independent output; usable for dual-channel filtering or differential drive |
| 8 | Positive Supply (VDD) | Power rail connection; requires local 0.1 μF ceramic bypass capacitor to GND |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply optimization | Input common-mode range includes GND and output swings to GND - eliminates level-shifting circuitry |
| Ultra-low input bias current | <60 pA typical at 25°C - enables use with >1 MΩ sensor sources without significant offset error |
| Low input voltage noise | 10.8 nV/√Hz at 1 kHz - outperforms bipolar op-amps in medium-impedance transducer interfaces |
| Latch-up immunity | Designed-in robustness against I/O overvoltage and supply sequencing faults - improves system reliability |
| ESD protection | Integrated circuitry rated per JEDEC JS-001 - withstands ≥2 kV HBM without external protection |

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 (1.5 mV max), lower supply current (1.25 mA typ), but narrower supply range (2.7–16 V) and reduced CMRR (60 dB min) | Better for battery-powered portable instruments needing tighter DC accuracy; less suitable for noisy industrial 5 V rails | Choose TLV272IDR when VIO < 1.5 mV is mandatory and supply headroom is limited below 4 V |
| OPA2333AIDR | Zero-drift architecture, 12 μV max VIO, 0.1 μV/°C drift, but higher cost and 1.8–5.5 V supply limit | Required for sub-μV-level precision in medical diagnostics or metrology; incompatible with 12 V systems | Choose OPA2333AIDR only when long-term DC stability and near-zero drift outweigh cost and voltage-range constraints |
Compared with TLV272IDR and OPA2333AIDR, the TLC272BIDR offers broader supply compatibility (4–16 V), proven latch-up immunity, and lower cost - making it optimal for industrial analog I/O where 2 mV VIO and –40°C to 85°C operation are sufficient.

FAQ
What is the maximum input offset voltage specification for TLC272BIDR at 25°C?
The TLC272BIDR has a maximum input offset voltage of 2000 µV (2 mV) at 25°C, as specified in the Electrical Characteristics table for the TLC272B grade under VDD = 5 V and TA = 25°C test conditions. This value applies across the full operating temperature range up to 3500 µV at 85°C.
Does TLC272BIDR support true rail-to-rail input operation?
The TLC272BIDR does not support rail-to-rail input - its common-mode input voltage range extends to –0.1 V (below ground) and up to VDD – 1.5 V. While this enables ground-referenced inputs in single-supply use, the upper limit excludes the positive rail, distinguishing it from true rail-to-rail input op-amps.
Can TLC272BIDR operate from a 3.3 V supply?
No - the TLC272BIDR requires a minimum supply voltage of 4 V, as defined in the Recommended Operating Conditions for I-suffix devices (–40°C to 85°C). A 3.3 V supply falls outside its specified operating range and may result in undefined behavior or failure to meet AC/DC specifications.
What is the thermal performance difference between TLC272BIDR and TLC272C-grade variants?
The TLC272BIDR (I-suffix) is rated for –40°C to 85°C operation, while the C-suffix TLC272C operates from 0°C to 70°C. Both share identical electrical specs at 25°C, but the I-grade guarantees 2000 µV max VIO and 0.3 µV/°C drift across its wider temperature span - critical for uncontrolled ambient deployments.
Is SOIC-8 packaging for TLC272BIDR lead-free and RoHS-compliant?
Yes - the TLC272BIDR in SOIC-8 (D) package is manufactured with lead-free terminations and complies with RoHS Directive 2011/65/EU, as confirmed in Texas Instruments' official packaging and environmental documentation for this orderable part number.
