Product details
Overview
TLV272IDRG4 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 per 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 TLV272IDRG4 datasheet, TLV272IDRG4 pinout, TLV272IDRG4 application, or TLV272IDRG4 equivalent, key selection criteria include rail-to-rail output swing at low supply voltages, ultra-low input bias current (1 pA), CMOS input stage compatibility with high-impedance sensors, and operation over –40°C to +125°C industrial temperature range.
Technical Context
The TLV272IDRG4 employs a CMOS input stage enabling 1 pA typical input bias current and >1 TΩ differential input resistance, supporting high-impedance sensor interfaces without loading error. Its rail-to-rail output stage uses complementary push-pull architecture to deliver output swing within 135 mV of either rail at 1 mA load, preserving dynamic range in single-supply 3.3 V or 5 V systems.
Internally compensated for unity-gain stability, it achieves 65° phase margin with 10 pF capacitive load and maintains 3 MHz bandwidth across 2.7 V–10 V supplies. The device operates fully specified for both single-supply (2.7 V–16 V) and split-supply (±1.35 V–±8 V) configurations, with common-mode input range extending from GND to VDD − 1.35 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports Li-ion (3.0–4.2 V), 5 V microcontroller rails, and ±5 V legacy systems without level-shifting. |
| Gain-Bandwidth Product | 3 MHz at VDD = 5 V - enables stable closed-loop operation up to ~300 kHz in unity-gain buffer or 100 kHz in gain-of-10 configuration. |
| Slew Rate | 2.4 V/µs at VDD = 5 V - supports clean 100-kHz sine-wave output at 2 VPP without distortion in sensor signal conditioning. |
| Input Bias Current | 1 pA typical - minimizes voltage error in photodiode, thermopile, or pH electrode interfaces with >100 MΩ source impedances. |
| Input Voltage Noise | 39 nV/√Hz at 1 kHz - ensures <1 µV RMS integrated noise in 10 Hz–10 kHz audio/sensor bands with proper filtering. |
| Rail-to-Rail Output | Swings to within 135 mV of VDD/GND at 1 mA - maximizes usable output range in 3.3 V ADC reference designs. |
| Quiescent Current | 550 µA per channel - allows dual opamp use in sub-1 mA total system standby power budgets. |
Pinout & Package
TLV272IDRG4 is packaged in an 8-pin VSSOP (DGK) with 3.00 mm × 3.00 mm body size and 0.65 mm lead pitch - optimized for space-constrained PCB layouts in portable instrumentation and building automation nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplified output of Channel 1 - drives ADC input, transducer load, or feedback network; rail-to-rail capable. |
| 2 | 1IN− | Inverting input of Channel 1 - connects to feedback resistor or sensor bridge leg; high-impedance CMOS node. |
| 3 | 1IN+ | Noninverting input of Channel 1 - interfaces directly with high-Z sensors (e.g., thermocouples, piezoelectrics). |
| 4 | GND | Analog ground reference - must be low-impedance star point shared with ADC and power supply return. |
| 5 | 2IN+ | Noninverting input of Channel 2 - independent signal path for dual-sensor monitoring or active filter stages. |
| 6 | 2IN− | Inverting input of Channel 2 - used for differential amplification, current sensing, or inverting gain configuration. |
| 7 | 2OUT | Amplified output of Channel 2 - isolated from Channel 1 for multi-channel signal chains or redundancy. |
| 8 | VDD | Positive supply rail - accepts 2.7–16 V; decoupling capacitor (0.1 µF ceramic) required within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Enables full-scale utilization of 3.3 V or 5 V ADCs without external level-shifting circuitry. |
| 1 pA input bias current | Eliminates significant offset drift in high-impedance pH, gas, or radiation sensor front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV272CDR | Same silicon, commercial-grade (0°C to 70°C) temperature range; identical electrical specs and pinout. | Not qualified for industrial environments requiring operation below 0°C or above 70°C. | Select TLV272CDR only for cost-sensitive consumer electronics where ambient temperature stays within 0–70°C. |
| TLV2372IDR | Includes shutdown control (active-low SHDN pin); otherwise matches GBW (3 MHz), IQ (550 µA), and rail-to-rail I/O. | Enables power cycling in intermittent-sensing applications (e.g., periodic smoke detector self-test) - TLV272IDRG4 lacks this feature. | Choose TLV2372IDR when system-level power management requires on-demand amplifier disable; TLV272IDRG4 is preferred for always-on signal paths. |
Compared with TLV272CDR, TLV272IDRG4 provides extended temperature operation critical for industrial deployments; versus TLV2372IDR, it eliminates shutdown logic overhead and reduces BOM count where continuous operation is required.

FAQ
What is the maximum operating temperature for TLV272IDRG4?
The TLV272IDRG4 is rated for continuous operation from –40°C to +125°C, meeting industrial temperature requirements. This specification is validated across all electrical parameters in the datasheet's Recommended Operating Conditions table, with thermal metrics (e.g., RθJA = 186.6°C/W for DGK package) confirming safe junction temperatures under typical PCB layouts at 125°C ambient.
Does TLV272IDRG4 support single-supply operation?
Yes, TLV272IDRG4 fully supports single-supply operation from 2.7 V to 16 V. Its input common-mode range extends from GND to VDD − 1.35 V, and rail-to-rail output swings within 135 mV of both rails at 1 mA load - enabling direct interfacing with 3.3 V or 5 V microcontrollers and ADCs without negative supply rails.
What is the input bias current of TLV272IDRG4 and why does it matter?
The TLV272IDRG4 has a typical input bias current of 1 pA, enabled by its CMOS input stage. This ultra-low value prevents significant voltage drop across high-impedance sensor sources (e.g., >100 MΩ thermopiles or pH electrodes), avoiding measurement errors and drift that would occur with bipolar-input opamps drawing nA-level currents.
Can TLV272IDRG4 drive capacitive loads?
TLV272IDRG4 can drive capacitive loads up to 10 pF stably; for larger loads (e.g., ADC input capacitance or long traces), Texas Instruments recommends adding a series resistor (RNULL ≥ 20 Ω) between the output and load to maintain ≥65° phase margin and prevent ringing or oscillation - as documented in Section 8.3.3 of the datasheet.
Is TLV272IDRG4 pin-compatible with other TLV27x variants?
TLV272IDRG4 shares identical 8-pin VSSOP (DGK) pinout with TLV272CDR and TLV272IDR, making it mechanically and electrically interchangeable within the dual-channel TLV272 family. However, it is not pin-compatible with TLV271 (5-pin SOT-23) or TLV274 (14-pin TSSOP/SOIC) due to differing channel counts and package footprints.
