Product details
Overview
TLV272IDGK 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 in smoke detectors and solar inverter monitoring circuits.
For engineers reviewing the TLV272IDGK datasheet, TLV272IDGK pinout, TLV272IDGK application, or TLV272IDGK equivalent, this page provides verified package mapping (VSSOP-8), confirmed dual-channel opamp identity, temperature-rated performance (−40°C to +125°C), rail-to-rail output swing capability, and real-world application context for portable instrumentation and building automation signal chains.
Technical Context
The TLV272IDGK employs CMOS input stage architecture with 1 pA typical input bias current, supporting high-impedance sensor interfaces such as thermistor or photodiode front-ends. Its rail-to-rail output stage achieves <0.22 V low-level and >2.48 V high-level output voltage swing at 2.7 V supply with 1 mA load - critical for maximizing dynamic range in single-supply microcontroller-based analog acquisition.
It operates across −40°C to +125°C with guaranteed 3 MHz unity-gain bandwidth and 65° phase margin into 10 pF capacitive load, making it suitable for stable closed-loop configurations in motor control feedback paths and power bank battery voltage monitoring without external compensation.
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), dual AA (2.4–3.2 V), and ±5 V industrial rails without level-shifting. |
| Gain-Bandwidth Product | 3 MHz - enables stable unity-gain buffer or 10× gain amplification up to 300 kHz for audio or sensor signal conditioning. |
| Slew Rate | 2.4 V/µs - supports 1 Vpp signals up to ~380 kHz without distortion in voltage-follower configuration. |
| Input Bias Current | 1 pA - minimizes voltage error in high-Z transducer interfaces (e.g., pH electrodes, piezoelectric sensors). |
| Input Voltage Noise | 39 nV/√Hz at 1 kHz - ensures <1 µV RMS noise in 10 kHz bandwidth, suitable for 12-bit ADC front-end with 1 V full-scale. |
| Output Swing | Rail-to-rail - delivers 0.15 V to VDD−0.1 V output range at 1 mA load, preserving >95% of supply headroom in low-voltage systems. |
| Quiescent Current | 550 µA per channel - allows dual-opamp operation on 10 µA standby rails in battery-powered smoke detectors. |
Pinout & Package
VSSOP-8 (DGK) package: 3.00 mm × 3.00 mm body, 0.65 mm lead pitch, exposed thermal pad (not electrically connected), moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplified output of Channel 1 - drives ADC input or next-stage filter with rail-to-rail swing capability. |
| 2 | 1IN− | Inverting input of Channel 1 - connects to feedback network in inverting amplifier or summing junction. |
| 3 | 1IN+ | Noninverting input of Channel 1 - accepts high-impedance sensor signal with 1 pA bias current loading. |
| 4 | GND | Reference node for single-supply operation - must be low-impedance plane to minimize PSRR degradation. |
| 5 | 2IN+ | Noninverting input of Channel 2 - independent input path enables dual-sensor monitoring (e.g., temp + humidity). |
| 6 | 2IN− | Inverting input of Channel 2 - supports differential measurement when paired with 2IN+ and matched resistors. |
| 7 | 2OUT | Amplified output of Channel 2 - can drive separate load or share common output bus with 1OUT via external OR-ing. |
| 8 | VDD | Positive supply rail - accepts 2.7–16 V; decoupling capacitor required within 5 mm for stability at 3 MHz. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDGKR | Includes shutdown pin; identical GBW, noise, and supply specs; same VSSOP-8 package. | Required where system-level power gating is needed (e.g., periodic sensor wake-up cycles). | Select TLV2372IDGKR only if active-low shutdown control is mandatory; otherwise TLV272IDGK offers lower cost and simpler layout. |
| LMV722MMX/NOPB | Higher 10 MHz GBW but 1.2 mA/ch supply current; SOIC-8 only; no −40°C to +125°C rating. | Suitable for higher-speed signal paths where power budget allows >2× current draw. | Choose LMV722MMX/NOPB for bandwidth-critical designs above 500 kHz; avoid in extended-temperature or ultra-low-power applications. |
Compared with TLV2372IDGKR and LMV722MMX/NOPB, the TLV272IDGK provides optimal balance of rail-to-rail output, 1 pA bias current, and industrial temperature range at lowest quiescent power - making it the preferred choice for battery longevity and sensor interface fidelity in safety-critical monitoring systems.

FAQ
What is the maximum operating temperature range for the TLV272IDGK?
The TLV272IDGK is rated for operation from −40°C to +125°C, meeting industrial temperature requirements. This specification is guaranteed across all electrical parameters in the datasheet, including input offset voltage drift, gain-bandwidth, and output swing - making TLV272IDGK suitable for under-hood automotive modules and outdoor solar inverter control units where ambient temperatures exceed 85°C.
Does the TLV272IDGK support single-supply operation?
Yes, the TLV272IDGK supports true single-supply operation from 2.7 V to 16 V. Its rail-to-rail output stage delivers output voltages within 0.15 V of GND and within 0.1 V of VDD at 1 mA load, and its input common-mode range extends from GND to VDD −1.35 V - enabling direct interfacing with 3.3 V or 5 V microcontrollers without level-shifting components in TLV272IDGK-based designs.
What is the input bias current specification for TLV272IDGK and why does it matter?
The TLV272IDGK has a typical input bias current of 1 pA, with a maximum of 1000 pA at 125°C. This ultra-low value minimizes voltage error when driving high-impedance sources such as thermistors, photodiodes, or pH electrodes - ensuring sub-millivolt offset in 1 MΩ sensor networks. For TLV272IDGK users designing precision analog front-ends, this parameter directly determines achievable accuracy without external bias cancellation.
Can TLV272IDGK drive capacitive loads, and what is the recommended approach?
The TLV272IDGK maintains 65° phase margin into 10 pF capacitive load but requires external isolation for larger loads. TI recommends placing a 20 Ω series resistor (RNULL) between TLV272IDGK output and capacitive load >10 pF - such as ADC input capacitance or long PCB traces - to prevent ringing or oscillation. This technique preserves stability without degrading bandwidth in TLV272IDGK-based filter or driver circuits.
How does the TLV272IDGK compare to the older TLC272 in terms of key performance metrics?
The TLV272IDGK improves upon TLC272 with 3 MHz vs. 1.7 MHz bandwidth, 550 µA vs. 675 µA per-channel supply current, and rail-to-rail output (TLC272 is not rail-to-rail). Both share 1 pA input bias current and 2.7–16 V supply range, but TLV272IDGK's wider bandwidth and lower power make it the preferred upgrade for battery-powered instruments and modern low-voltage industrial controls where TLC272 was previously used.
