Product details
Overview
TLV272IDGKRG4 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 unity-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 E-bikes, smoke detectors, and solar inverters.
For engineers reviewing the TLV272IDGKRG4 datasheet, TLV272IDGKRG4 pinout, TLV272IDGKRG4 application, or TLV272IDGKRG4 equivalent, key selection criteria include rail-to-rail output swing at low supply voltages, ultra-low 1 pA input bias current for high-impedance sensor interfaces, and guaranteed operation from −40°C to +125°C in the 8-pin VSSOP package.
Technical Context
The TLV272IDGKRG4 uses CMOS input stage architecture to achieve 1 pA typical input bias current and rail-to-rail output swing down to within 135 mV of each rail at 1 mA load. Its 3-MHz gain-bandwidth product and 2.4 V/µs slew rate are specified across the full 2.7 V–16 V supply range and −40°C to +125°C temperature range.
It operates with single-supply (2.7 V to 16 V) or split-supply (±1.35 V to ±8 V) configurations, supports common-mode input voltage from ground to VDD − 1.35 V, and exhibits 70 dB minimum PSRR and 55 dB minimum CMRR over temperature - making it suitable for noisy industrial environments and precision DC-coupled signal paths.
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 logic rails, and ±5 V industrial supplies without level-shifting. |
| Bandwidth (UGBW) | 3 MHz - enables stable closed-loop gain up to ~10× at 300 kHz for sensor amplification and filtering. |
| Slew Rate | 2.4 V/µs - supports 1 VPP signals up to ~380 kHz without distortion in unity-gain buffer configuration. |
| Input Bias Current | 1 pA - minimizes voltage error in high-Z sources (e.g., pH electrodes, photodiodes, thermistors). |
| Input Noise Voltage | 39 nV/√Hz at 1 kHz - ensures <1 µV RMS integrated noise in 10 kHz bandwidth for precision measurement. |
| Rail-to-Rail Output | Swings to within 135 mV of VDD and GND at 1 mA - maximizes dynamic range in low-voltage single-supply systems. |
| Quiescent Current | 550 µA per channel - allows dual opamp operation on microamp-level power budgets (e.g., wireless sensor nodes). |
Pinout & Package
TLV272IDGKRG4 is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm with 0.5-mm lead pitch. This thermally enhanced, surface-mount package supports high-density PCB layouts and provides improved thermal resistance (RθJA = 186.6°C/W) compared to SOIC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives loads up to ±100 mA; rail-to-rail swing enables full utilization of ADC reference range. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node; requires matched trace impedance for optimal CMRR. |
| 3 | 1IN+ | Noninverting input of Channel 1 - used for unity-gain buffers, differential receivers, and precision reference followers. |
| 4 | GND | Negative supply terminal - must be connected to low-impedance ground plane to maintain PSRR and minimize crosstalk. |
| 5 | 2IN+ | Noninverting input of Channel 2 - independent of Channel 1; enables dual-path signal conditioning on one die. |
| 6 | 2IN− | Inverting input of Channel 2 - supports fully differential configurations when paired with external resistors. |
| 7 | 2OUT | Output of Channel 2 - electrically isolated from Channel 1; crosstalk < −80 dB at 100 kHz per datasheet Figure 24. |
| 8 | VDD | Positive supply terminal - accepts 2.7–16 V; decoupling capacitor (0.1 µF ceramic) required within 2 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers usable signal headroom down to 135 mV from each rail at 1 mA load - critical for 3.3 V and lower MCU/ADC systems. |
| Ultra-low input bias current (1 pA) | Enables direct connection to >1 GΩ sensors without significant offset drift or loading error. |
| 3-MHz bandwidth at 550 µA/ch | Provides 5.5× higher speed-per-microwatt than legacy TLC272 - extends battery life in portable instrumentation. |
| −40°C to +125°C operation | Qualified for industrial and automotive under-hood applications where ambient temperature exceeds 85°C. |
| CMOS input stage | Eliminates input protection diodes - prevents latch-up and enables safe operation beyond supply rails during power sequencing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV272IDR | Same electrical specs; SOIC-8 package (4.98 mm × 3.91 mm), higher RθJA (127.2°C/W), no thermal pad. | Better suited for prototyping or through-hole assembly; less space-constrained than VSSOP. | Select TLV272IDR if board layout allows larger footprint and thermal management is handled via copper pour. |
| TLV2372IDGKR | Includes shutdown control (pin 1), same 3-MHz GBW, but 1.5× higher input bias current (1.5 pA typ) and 2.8 V/µs slew rate. | Required where power gating is needed between sensor readings to extend battery life beyond TLV272IDGKRG4's fixed 550 µA draw. | Choose TLV2372IDGKR only when active shutdown functionality is mandatory and 1.5 pA bias current is acceptable. |
Compared with TLV272IDR and TLV2372IDGKR, TLV272IDGKRG4 offers the smallest PCB footprint and lowest thermal resistance among pin-compatible dual opamps in the TLV27x family, while maintaining the lowest input bias current - making it optimal for miniaturized, high-reliability industrial sensor modules.

FAQ
What is the operating temperature range of the TLV272IDGKRG4?
The TLV272IDGKRG4 is rated for industrial operation from −40°C to +125°C. This range is guaranteed per the I-suffix qualification and applies to all electrical specifications in the datasheet, including input offset voltage drift (2 µV/°C), CMRR (≥55 dB), and output drive capability. The VSSOP package's thermal metrics (RθJA = 186.6°C/W) support this rating in typical PCB layouts with 1-in² 2-oz copper.
Does the TLV272IDGKRG4 support single-supply operation?
Yes, the TLV272IDGKRG4 supports true single-supply operation from 2.7 V to 16 V. Its input common-mode range extends from GND to VDD − 1.35 V, and its rail-to-rail output swings within 135 mV of both supply rails at 1 mA load. This allows direct interfacing with 3.3 V or 5 V ADCs and microcontrollers without level-shifting circuitry.
What is the input bias current specification for TLV272IDGKRG4?
The TLV272IDGKRG4 has a maximum input bias current of 1000 pA at 125°C and 60 pA at 25°C, with a typical value of 1 pA at 25°C. This ultra-low bias current results from its CMOS input stage and enables accurate amplification of signals from high-impedance sources such as photodiodes, pH electrodes, and thermistors without significant voltage error.
Can TLV272IDGKRG4 drive capacitive loads?
The TLV272IDGKRG4 can drive capacitive loads up to 10 pF stably. For loads exceeding 10 pF, Texas Instruments recommends adding a series resistor (RNULL ≥ 20 Ω) between the output pin and the capacitive load to preserve phase margin and prevent oscillation - as documented in Section 8.3.3 of the SLOS351E datasheet.
Is TLV272IDGKRG4 pin-compatible with other TLV27x variants?
Yes, TLV272IDGKRG4 shares identical pinout and function mapping with all TLV272 variants in SOIC (D), VSSOP (DGK), and PDIP (P) packages. Pin 1 is 1OUT, Pin 2 is 1IN−, Pin 3 is 1IN+, Pin 4 is GND, Pin 5 is 2IN+, Pin 6 is 2IN−, Pin 7 is 2OUT, and Pin 8 is VDD - confirmed in Section 6 of the TLV27x datasheet.
