Product details
Overview
TLV272CDRG4 from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-power, wide-bandwidth signal conditioning in battery-powered and industrial systems. It delivers 3-MHz gain-bandwidth, 2.4 V/µs slew rate, 550 µA/channel supply current, 39 nV/√Hz input noise, and operates from 2.7 V to 16 V across –40°C to 125°C. It serves as a direct upgrade for TLC27x in sensor interfaces and Li-ion powered instrumentation.
For engineers reviewing the TLV272CDRG4 datasheet, TLV272CDRG4 pinout, TLV272CDRG4 application, or TLV272CDRG4 equivalent, key selection criteria include rail-to-rail output swing at low supply voltage, ultra-low 1-pA input bias current for high-impedance sources, and guaranteed performance over extended temperature range without thermal derating.
Technical Context
The TLV272CDRG4 uses CMOS input stage architecture enabling picoampere-level input bias current and high input impedance, critical for precision sensor front-ends. Its rail-to-rail output stage employs complementary push-pull transistors to achieve <150-mV saturation voltage near both supply rails under 1-mA load.
It supports single-supply operation down to 2.7 V and split-supply operation from ±1.35 V to ±8 V, with common-mode input range extending from GND to VDD −1.35 V. The device exhibits stable unity-gain operation with ≥65° phase margin into 10-pF capacitive loads when properly compensated.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - enables compatibility with Li-ion (3.0–4.2 V), 5-V logic, and ±5-V industrial rails |
| Gain-Bandwidth Product | 3 MHz - supports closed-loop bandwidth up to ~2.4 MHz at unity gain with stable phase margin |
| Slew Rate | 2.4 V/µs - ensures ≤2 µs settling time for 1-V step with 0.1% accuracy in buffer configurations |
| Input Bias Current | 1 pA - minimizes voltage error in high-Z sensor circuits (e.g., pH electrodes, photodiodes) |
| Input Noise Voltage | 39 nV/√Hz - limits contribution to total system noise in precision DC-coupled amplifiers |
| Rail-to-Rail Output | Swings within 150 mV of VDD and GND at 1 mA - maximizes dynamic range in low-voltage systems |
| Quiescent Current | 550 µA per channel - allows dual op-amp operation in micropower applications (<1.2 mW at 5 V) |
Pinout & Package
TLV272CDRG4 is packaged in an 8-pin SOIC (D package) with 4.98 mm × 3.91 mm body size and standard 1.27-mm pitch. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives external load; capable of sourcing/sinking ≥4 mA near rails |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node; sensitive to PCB leakage and ESD |
| 3 | 1IN+ | Noninverting input of Channel 1 - matched to Pin 2 for optimal common-mode rejection |
| 4 | GND | Negative supply reference - must be low-impedance path to minimize ground bounce in dual-channel operation |
| 5 | 2IN+ | Noninverting input of Channel 2 - electrically isolated from Channel 1 inputs; shares same substrate |
| 6 | 2IN− | Inverting input of Channel 2 - independent high-Z node; layout symmetry recommended vs. Pins 2–3 |
| 7 | 2OUT | Output of Channel 2 - fully independent output stage; crosstalk < −80 dB at 10 kHz |
| 8 | VDD | Positive supply - decoupling capacitor (0.1 µF ceramic) required within 5 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale analog range in 3-V systems - eliminates need for level-shifting or dual supplies |

| 3-MHz bandwidth at 550 µA | Provides 5× higher speed per µA than legacy TLC27x - improves loop response in motor control feedback |
| –40°C to +125°C operation | Qualified for industrial ambient environments - no derating required up to maximum junction temperature |
| CMOS input stage | Reduces input current mismatch versus bipolar op-amps - critical for precision integrators and I/V converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV272IDR | Same electrical specs but rated for –40°C to +125°C industrial grade (I-suffix); identical SOIC-8 packaging | Required for designs needing full industrial temperature qualification; C-suffix (TLV272CDRG4) is commercial grade (0°C to 70°C) | Select TLV272IDR if operating ambient exceeds 70°C or requires AEC-Q200 stress testing compliance |
| TLV2372IDR | Includes shutdown control (SHDN pin); otherwise matches bandwidth, noise, and supply current; same SOIC-8 footprint | Enables power cycling of unused channel in battery systems - reduces idle current to <1 µA per channel | Choose TLV2372IDR only if active power management is required; adds complexity in non-shutdown designs |
Compared with TLV272CDRG4, TLV272IDR offers extended temperature reliability without trade-offs in performance or layout, while TLV2372IDR adds shutdown capability at the cost of one extra control pin and slightly higher input offset voltage (500 µV vs. 5 mV typical).

FAQ
What is the operating temperature range specified for TLV272CDRG4?
The TLV272CDRG4 is rated for commercial-grade operation from 0°C to 70°C. This is explicitly defined by the 'C' suffix in the part number. While the underlying silicon may function beyond this range, TI guarantees all electrical specifications only within this interval. For extended temperature applications, the TLV272IDR (I-suffix) variant is qualified from –40°C to +125°C and shares identical pinout and functionality with TLV272CDRG4.
Does TLV272CDRG4 support true rail-to-rail input common-mode range?
No, TLV272CDRG4 does not support rail-to-rail input. Its common-mode input voltage range is specified from GND to VDD −1.35 V at 25°C. This means the upper limit falls 1.35 V below the positive supply rail - sufficient for most single-supply applications using mid-supply biasing, but incompatible with direct connection to VDD-referenced signals. The rail-to-rail capability applies exclusively to the output stage, not the input stage.
Can TLV272CDRG4 drive a 10-kΩ load while maintaining rail-to-rail output swing?
Yes, TLV272CDRG4 maintains rail-to-rail output swing into 10-kΩ loads. Electrical Characteristics tables confirm VOH ≥ 4.9 V and VOL ≤ 0.1 V at VDD = 5 V and IO = ±1 mA. Since 10-kΩ at 5 V draws only 0.5 mA, the device easily meets rail-to-rail performance under this condition. Output swing degrades only under heavier loads (>5 mA) or near temperature extremes.
Is TLV272CDRG4 pin-compatible with the TLC272 series?
Yes, TLV272CDRG4 is pin-compatible with TLC272 in SOIC-8 (D) package. Both share identical pinout: Pin 1 (OUT1), Pin 2 (IN1−), Pin 3 (IN1+), Pin 4 (GND), Pin 5 (IN2+), Pin 6 (IN2−), Pin 7 (OUT2), Pin 8 (VDD). However, TLV272CDRG4 offers improved rail-to-rail output, lower supply current (550 µA vs. 675 µA), and wider bandwidth (3 MHz vs. 1.7 MHz), making it a functional upgrade without PCB changes.
What decoupling capacitance is recommended for TLV272CDRG4?
A minimum 0.1-µF ceramic capacitor placed within 5 mm of Pin 8 (VDD) and Pin 4 (GND) is required for stable operation. TI's datasheet recommends pairing this with a bulk 4.7-µF tantalum or aluminum electrolytic capacitor on the same supply rail if multiple devices share the rail. This dual-capacitor strategy suppresses both high-frequency switching noise and low-frequency supply droop, ensuring consistent 3-MHz bandwidth and low-noise performance in TLV272CDRG4 circuits.
