Product details
Overview
TLV272CDG4 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, 39 nV/√Hz input voltage noise, and operates from 2.7 V to 16 V across –40°C to 125°C. It serves as a direct upgrade path for TLC27x-family designs requiring full output swing near supply rails.
For engineers reviewing the TLV272CDG4 datasheet, TLV272CDG4 pinout, TLV272CDG4 application, or TLV272CDG4 equivalent, key selection criteria include rail-to-rail output drive capability under 550 µA quiescent current, CMOS-input ultra-low bias current (1 pA), and compatibility with Li-ion, MSP430, and other micropower microcontroller interfaces.
Technical Context
The TLV272CDG4 implements a CMOS-input stage enabling high-impedance sensor interfacing and ultra-low input bias current (1 pA typ). Its rail-to-rail output stage uses complementary push-pull architecture to achieve VOH ≥ 2.55 V and VOL ≤ 0.15 V at 2.7 V supply with 1 mA load - critical for maximizing dynamic range in single-supply systems.
It supports stable operation with capacitive loads up to 10 pF; beyond that, a series nulling resistor (≥20 Ω) is recommended to maintain ≥65° phase margin. The device is fully specified for both single-supply (2.7–16 V) and split-supply (±1.35–±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 - enables direct use with Li-ion (3.0–4.2 V), 5 V logic, and ±5 V analog rails without level-shifting. |
| Gain-Bandwidth Product | 3 MHz - supports stable unity-gain buffer or closed-loop amplification up to ~50 kHz with second-order filter design. |
| Slew Rate | 2.4 V/µs - ensures <2 µs settling to 0.1% for 1 V step at 5 V supply, suitable for fast-sampling sensor front-ends. |
| Input Bias Current | 1 pA typical - preserves signal integrity in high-Z pH sensors, photodiode transimpedance, and precision thermistor bridges. |
| Input Voltage Noise | 39 nV/√Hz at 1 kHz - enables sub-10 µV RMS noise in 10 kHz bandwidth, critical for low-level biopotential or strain gauge signals. |
| Rail-to-Rail Output Swing | VOL ≤ 0.15 V / VOH ≥ 2.55 V @ 2.7 V, 1 mA - delivers >94% of full-scale output range, maximizing ADC utilization in 3.3 V systems. |
| Operating Temperature | –40°C to +125°C (I-suffix) - qualified for automotive cabin, solar inverter control, and industrial motor drive environments. |
Pinout & Package
TLV272CDG4 is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm with 0.65 mm pitch, optimized for space-constrained portable and embedded applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, Channel 1 | Amplified output node for first opamp; capable of sourcing/sinking ≥4 mA while maintaining rail-to-rail swing. |

| 2IN+ | Noninverting Input, Channel 2 | Reference-side input for second opamp; accepts common-mode voltages from GND to VDD −1.35 V. |
| GND | Negative Supply / Ground | Return path for both channels; must be low-impedance to minimize crosstalk and offset drift. |
| 1IN+ | Noninverting Input, Channel 1 | Reference-side input for first opamp; identical electrical characteristics to 2IN+. |
| 1IN− | Inverting Input, Channel 1 | Differential input terminal for first opamp; matches 2IN− in bias current and noise performance. |
| 2OUT | Output, Channel 2 | Amplified output node for second opamp; electrically isolated from 1OUT but shares same supply and thermal environment. |
| VDD | Positive Supply | Single or positive rail connection; supports up to 16.5 V absolute max; decoupling capacitor required at pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Delivers >94% of full-scale swing at 2.7 V supply, preserving ADC resolution in low-voltage battery systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDGKR | Includes shutdown pin; 3-MHz GBW, 2.4 V/µs SR, but higher 650 µA/ch supply current; same 1 pA IIB. | Required where system-level power gating is needed; not drop-in due to extra SHDN pin and different pinout. | Select TLV2372IDGKR only when active power management is mandatory and PCB layout allows pin reassignment. |
| TLC2272CD | Higher 1100 µA/ch supply current; lower 2.2 MHz GBW; wider 2.7–16 V range; no rail-to-rail output (VOL = 0.7 V min @ 5 V). | Suitable for non-critical, higher-power industrial analog front-ends where output swing margin is acceptable. | Choose TLC2272CD only if existing design already uses it and rail-to-rail output is unnecessary; avoid for new battery-sensitive designs. |
Compared with TLV2372IDGKR and TLC2272CD, TLV272CDG4 provides optimal balance of rail-to-rail output, 550 µA efficiency, and 3-MHz bandwidth - making it the preferred choice for space- and power-constrained applications where full output swing and low noise are essential.

FAQ
What is the maximum supply voltage for TLV272CDG4?
The absolute maximum supply voltage for TLV272CDG4 is 16.5 V, with recommended operation up to 16 V. Exceeding this may cause permanent damage. For long-term reliability in 12 V systems, TI recommends derating to ≤15 V and using proper input transient protection.
Does TLV272CDG4 support rail-to-rail input?
No, TLV272CDG4 does not feature rail-to-rail input. Its common-mode input voltage range is specified from GND to VDD −1.35 V. At 2.7 V supply, this limits usable input to 0–1.35 V; at 5 V, it extends to 0–3.65 V. Input signals beyond this range may cause phase reversal or increased offset.
What package type is TLV272CDG4 supplied in?
TLV272CDG4 is supplied in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm with 0.65 mm lead pitch. This ultra-small outline package is pin-compatible with SOIC-8 but occupies ~45% less board area, ideal for compact portable electronics.
Can TLV272CDG4 drive capacitive loads directly?
TLV272CDG4 remains stable with capacitive loads ≤10 pF. For larger loads (e.g., ADC input capacitance or long traces), TI recommends adding a 20–100 Ω series resistor between the output and load to preserve ≥65° phase margin and prevent ringing. This is documented in Section 8.3.3 of the datasheet.
Is TLV272CDG4 suitable for automotive applications?
Yes - TLV272CDG4 is rated for operation from –40°C to +125°C (I-suffix), meeting AEC-Q100 stress test requirements for temperature grade 1. It is widely deployed in automotive cabin modules, battery management subsystems, and ADAS sensor signal conditioning where rail-to-rail output and low quiescent current are critical.
