Product details
Overview
TLV272CDGK 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 Li-ion–powered instrumentation and motor control.
For engineers reviewing the TLV272CDGK datasheet, TLV272CDGK pinout, TLV272CDGK application, or TLV272CDGK equivalent, key selection criteria include rail-to-rail output swing at low supply voltage, ultra-low input bias current (1 pA), thermal performance in VSSOP packaging, and compatibility with micropower microcontrollers such as TI's MSP430.
Technical Context
The TLV272CDGK employs CMOS input stages enabling high-impedance sensor interfacing, and 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 specified across the full industrial temperature range (−40°C to +125°C) with 550 µA/channel quiescent current.
It operates on single supplies from 2.7 V to 16 V or split supplies from ±1.35 V to ±8 V, with common-mode input range extending from ground to VDD − 1.35 V. Input offset voltage is 5 mV typical (7 mV max over full temperature range), and PSRR is 70 dB minimum - supporting stable performance in noisy power environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - enables direct use with Li-ion cells (3.0–4.2 V), 5 V rails, and ±5 V systems without level-shifting. |
| Gain-Bandwidth Product | 3 MHz - supports closed-loop amplification up to ~200 kHz at gain = 15 while maintaining phase margin >65°. |
| Slew Rate | 2.4 V/µs - ensures <2 µs settling to 0.1% for 1-V step inputs, suitable for fast-sampling data acquisition. |
| Input Bias Current | 1 pA - minimizes voltage error in high-impedance transducer interfaces (e.g., pH electrodes, photodiode TIA feedback). |
| Input Noise Voltage | 39 nV/√Hz - provides low-noise amplification for sub-mV sensor signals without requiring additional filtering. |
| Quiescent Current | 550 µA per channel - allows dual-channel operation in systems with <1.2 mA total analog supply budget. |
| Rail-to-Rail Output | Swings within 150 mV of both rails at 1 mA load - maximizes usable output dynamic range in low-voltage systems. |
Pinout & Package
TLV272CDGK is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm with 0.5-mm lead pitch - optimized for space-constrained PCB layouts in portable and industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives loads up to ±100 mA; rail-to-rail swing supports direct interface to ADC reference buffers or comparator inputs. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node; requires matched trace impedance for balanced noise rejection in differential configurations. |
| 3 | 1IN+ | Noninverting input of Channel 1 - used for unity-gain buffer or active filter configurations; sensitive to PCB leakage above 100 MΩ. |
| 4 | GND | Analog ground reference - must be connected to low-impedance ground plane; separates analog return from digital or power ground paths. |
| 5 | 2IN+ | Noninverting input of Channel 2 - independent of Channel 1; enables dual-path signal conditioning (e.g., sensor + reference channel). |
| 6 | 2IN− | Inverting input of Channel 2 - supports differential input stages or inverting amplifier topologies with separate gain-setting resistors. |
| 7 | 2OUT | Output of Channel 2 - electrically isolated from Channel 1 output; allows simultaneous drive of two independent analog subsystems. |
| 8 | VDD | Positive supply rail - accepts 2.7–16 V; decoupling capacitor (0.1 µF ceramic) required within 2 mm of pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale output at 2.7 V supply - eliminates need for level-shifting circuitry in low-voltage MCU-based systems. |
| Ultra-low input bias current (1 pA) | Enables accurate amplification of high-impedance sources (e.g., piezoelectric sensors, ion-selective electrodes) without significant DC error. |
| 3-MHz bandwidth at 550 µA | Provides high-speed signal fidelity without compromising battery life - ideal for real-time monitoring in portable medical devices. |
| Specified from −40°C to +125°C | Guarantees parametric performance in automotive under-hood, industrial PLC, and solar inverter environments without derating. |
| CMOS input architecture | Reduces input current noise and enables operation with supply voltages compatible with modern micropower MCUs (e.g., MSP430, EFM32). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual opamp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDGKR | Includes shutdown mode; identical GBW (3 MHz), lower input offset (500 µV typ), but higher supply current (650 µA/ch). | Preferred where power cycling is required between measurements - e.g., intermittent sensor polling in IoT nodes. | Select TLV2372IDGKR only if shutdown functionality is needed; otherwise TLV272CDGK offers lower quiescent current. |
| LMV722MMX/NOPB | Higher GBW (10 MHz), faster slew rate (5.5 V/µs), but higher supply current (1.3 mA/ch) and no rail-to-rail output (1.2 V headroom). | Suitable for higher-speed signal chains where output swing margin is acceptable - e.g., audio preamps or fast-settling DAC buffers. | Choose LMV722MMX/NOPB when bandwidth >5 MHz is required; avoid if rail-to-rail output or <600 µA/ch is mandatory. |
Compared with TLV2372IDGKR and LMV722MMX/NOPB, TLV272CDGK uniquely balances ultra-low quiescent current, rail-to-rail output, and industrial temperature rating - making it optimal for always-on, space-constrained, battery-sensitive applications where power efficiency and output range are primary constraints.

FAQ
What is the maximum recommended supply voltage for TLV272CDGK?
The absolute maximum supply voltage for TLV272CDGK is 16.5 V, but the maximum recommended operating supply voltage is 16 V. Operation beyond this may cause permanent damage or accelerated aging. The device is fully characterized from 2.7 V to 16 V, supporting single-supply (2.7–16 V) and split-supply (±1.35 V to ±8 V) configurations. Always observe derating guidelines for extended temperature operation.
Does TLV272CDGK support rail-to-rail input capability?
No, TLV272CDGK does not feature rail-to-rail input. Its common-mode input voltage range is specified from ground to VDD − 1.35 V. This means the input cannot reliably operate within 1.35 V of the positive rail. However, the output is rail-to-rail - swinging within ~150 mV of both supply rails under 1 mA load. For true rail-to-rail input/output, consider TI's TLV2462 or newer TLV9002.
What is the thermal resistance (RθJA) of TLV272CDGK in its VSSOP package?
The junction-to-ambient thermal resistance (RθJA) for TLV272CDGK in the DGK (VSSOP-8) package is 186.6°C/W, as measured per JEDEC JESD51-7 standard on a 1-in², 2-layer board with 2-oz copper. This value assumes no thermal vias or copper pour. For improved thermal performance, TI recommends adding thermal vias under the exposed pad (if present) and using ≥4 cm² of 2-oz copper on the top layer connected to GND.
Can TLV272CDGK drive capacitive loads directly?
TLV272CDGK can drive capacitive loads ≤10 pF stably without external compensation. For loads >10 pF (e.g., ADC input capacitance, long traces), TI recommends inserting a series resistor (RNULL ≥20 Ω) between the output and the load to maintain phase margin >65° and prevent ringing or oscillation. This is documented in Section 8.3.3 of the TLV27x datasheet and verified in Figure 16 (Phase Margin vs Capacitive Load).
Is TLV272CDGK qualified for automotive applications?
TLV272CDGK is not AEC-Q200 qualified and carries the 'C' temperature suffix (0°C to 70°C), indicating commercial-grade specification. However, the TLV272IDGKR variant (I-suffix) is rated for −40°C to +125°C and is commonly used in automotive body electronics where qualification is customer-responsible. For full AEC-Q200 compliance, TI recommends the TLV9062-Q1 or OPA2333-Q1 as drop-in alternatives with automotive qualification.
