Product details
Overview
TLV272IP 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, and 39 nV/√Hz input voltage noise across a 2.7-V to 16-V supply range - enabling precision sensing and analog front-end design in smoke detectors and solar inverters.
For engineers reviewing the TLV272IP datasheet, TLV272IP pinout, TLV272IP application, or TLV272IP equivalent, key selection criteria include rail-to-rail output swing at low supply voltages, ultra-low input bias current (1 pA), wide temperature operation (–40°C to +125°C), and compatibility with Li-ion and MSP430-based systems.
Technical Context
The TLV272IP uses CMOS input stages to achieve 1-pA input bias current and high-impedance sensor interfacing, while its rail-to-rail output stage supports full dynamic range utilization down to 2.7-V single-supply operation. Its 3-MHz unity-gain bandwidth and 2.4 V/µs slew rate are maintained across ±1.35-V to ±8-V split supplies or 2.7-V to 16-V single supplies.
It is fully specified for DC precision (5-mV max input offset voltage), AC performance (65° phase margin into 10-pF load), and noise (39 nV/√Hz at 1 kHz), with thermal metrics confirming suitability for SOIC-8 packaging in ambient temperatures up to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports direct integration with Li-ion cells (3.0–4.2 V), MSP430 MCUs, and industrial ±5-V rails. |
| Gain-Bandwidth Product | 3 MHz - enables stable closed-loop operation up to ~100-kHz in unity-gain buffer or second-order filter configurations. |
| Slew Rate | 2.4 V/µs - ensures <2-µs settling for 1-V step inputs, critical for fast-response sensor amplification. | Input Bias Current | 1 pA - preserves signal integrity in high-impedance pH, photodiode, or thermocouple interfaces. |
| Input Voltage Noise | 39 nV/√Hz at 1 kHz - limits added noise in precision instrumentation chains below 100-kHz bandwidth. |
| Rail-to-Rail Output | Swings within 150 mV of both rails at 1-mA load - maximizes usable dynamic range in low-voltage ADC driver applications. |
| Operating Temperature | –40°C to +125°C (I-suffix) - qualified for under-hood automotive, solar inverter, and building automation environments. |
Pinout & Package
TLV272IP is housed in an 8-pin SOIC package (body size 4.98 mm × 3.91 mm) with standard JEDEC MS-012AC footprint and 1.27-mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives external load or feedback network; rail-to-rail capable with 1-mA sourcing/sinking. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node; connects to feedback resistor in inverting amplifier configurations. |
| 3 | 1IN+ | Noninverting input of Channel 1 - referenced to sensor or reference voltage; immune to 1-pA bias current errors. |
| 4 | GND | Negative supply terminal - serves as common return for both channels and PCB ground plane reference. |
| 5 | 2IN+ | Noninverting input of Channel 2 - electrically isolated from Channel 1; enables dual independent signal paths. |
| 6 | 2IN− | Inverting input of Channel 2 - used for differential amplification or active filtering with separate gain-setting resistors. |
| 7 | 2OUT | Output of Channel 2 - independently buffered output; supports dual-channel signal conditioning without crosstalk degradation. |
| 8 | VDD | Positive supply terminal - accepts 2.7–16 V; powers both op-amp cores and output stages simultaneously. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Enables full-scale utilization of 12-bit ADCs powered from 3.3-V rails without level-shifting circuitry. |
| 550 µA/channel quiescent current | Extends battery life in E-bike controllers and portable instruments beyond 1000 hours on two AA cells. |
| 1 pA input bias current | Eliminates voltage error in 10-MΩ sensor bridges, preserving accuracy in smoke detector ionization chambers. |
| 3-MHz bandwidth at low power | Supports anti-aliasing filtering and motor current sensing up to 50-kHz PWM frequencies in low-power motor controls. |
| –40°C to +125°C operation | Meets industrial temperature requirements for solar inverter string monitoring and building automation sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV272IDR | Tape-and-reel variant in same SOIC-8 package; identical electrical specs and thermal performance. | No functional difference; optimized for automated SMT assembly rather than manual prototyping. | Select TLV272IDR for volume production; TLV272IP remains preferred for evaluation and low-quantity builds. |
| TLV2372IP | Includes shutdown control (active-low SHDN pin); higher 650 µA/channel supply current; same 3-MHz GBW and 1-pA IIB. | Required where system-level power gating is needed; adds PCB routing complexity for enable logic. | Choose TLV2372IP only when dynamic power cycling is mandated; TLV272IP offers simpler layout and lower static current. |
Compared with TLV272IDR and TLV2372IP, the TLV272IP provides optimal balance of low quiescent current, rail-to-rail output, and SOIC-8 manufacturability - making it the default choice for cost-sensitive, thermally demanding industrial analog designs without shutdown requirements.

FAQ
What is the maximum supply voltage rating for TLV272IP?
The absolute maximum supply voltage for TLV272IP is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Operation above 16 V risks permanent damage, while operation below 2.7 V may cause output saturation or increased input offset voltage drift. TI specifies full performance across this range for both single-supply (2.7–16 V) and split-supply (±1.35 V to ±8 V) configurations.
Does TLV272IP support rail-to-rail input capability?
No, TLV272IP features rail-to-rail *output* only. Its input common-mode voltage range is 0 V to VDD − 1.35 V - meaning the inputs cannot operate within 1.35 V of the positive rail. This limitation must be considered when designing noninverting amplifiers or level-shifted sensor interfaces; however, the 1-pA input bias current minimizes errors across the supported input range.
Can TLV272IP drive capacitive loads directly?
TLV272IP can drive ≤10 pF capacitive loads stably without external compensation. For loads exceeding 10 pF - such as ADC input capacitance or long PCB traces - TI recommends adding a 20-Ω series resistor (RNULL) between the output pin and the load to maintain ≥65° phase margin and prevent oscillation, as verified in Figure 16 of the SLOS351E datasheet.
What is the thermal resistance (RθJA) of TLV272IP in SOIC-8 package?
The junction-to-ambient thermal resistance (RθJA) for TLV272IP in SOIC-8 (D package) is 127.2°C/W under standard JEDEC JESD51-2 conditions. This value assumes a 2-layer board with 1-in² copper pour; actual board-level thermal performance depends on PCB layout, copper area, and airflow. For high-temperature operation near 125°C, thermal design must ensure power dissipation stays below 315 mW to limit junction temperature rise.
Is TLV272IP pin-compatible with TLC272?
TLV272IP is not pin-compatible with TLC272. While both are dual op-amps in SOIC-8, the TLC272 uses a different pinout: TLC272 assigns Pin 1 to VDD, whereas TLV272IP uses Pin 1 for 1OUT. Substituting TLV272IP for TLC272 requires PCB redesign. However, TLV272IP is a functional upgrade offering rail-to-rail output, lower supply current (550 µA vs 675 µA), and improved noise performance (39 nV/√Hz vs 55 nV/√Hz).
