Product details
Overview
TLV272QDRG4Q1 from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier qualified for automotive applications (−40°C to 125°C), featuring 3-MHz unity-gain bandwidth, 2.4 V/µs slew rate, and 550 µA per channel supply current at 2.7–16 V supply. It delivers rail-to-rail output swing in battery-powered sensor interfaces and low-voltage microcontroller systems such as TI MSP430-based automotive ECUs.
For engineers reviewing the TLV272QDRG4Q1 datasheet, TLV272QDRG4Q1 pinout, TLV272QDRG4Q1 application, or TLV272QDRG4Q1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, CMOS input stage (1 pA bias current), 39 nV/√Hz input voltage noise, and SOIC-8 packaging compatible with legacy PCB layouts requiring dual op-amp functionality under extended temperature operation.
Technical Context
The TLV272QDRG4Q1 employs a CMOS input stage enabling ultra-low input bias current (1 pA typical) and high input impedance, making it suitable for precision high-impedance sensor signal conditioning. Its rail-to-rail output stage supports full dynamic range utilization across 2.7 V to 16 V single-supply or ±1.35 V to ±8 V split-supply operation.
Designed for stability with capacitive loads up to 10 pF, the device requires external series output resistance (RNULL ≥ 20 Ω) when driving larger capacitive loads to maintain ≥65° phase margin. It achieves 3 MHz bandwidth while consuming only 550 µA per channel - a 18% reduction versus TLC272-Q1 - enabling micropower analog front-ends without sacrificing speed.
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 12 V automotive systems without level-shifting. |
| Bandwidth (UGBW) | 3 MHz - enables accurate amplification of signals up to ~1.5 MHz at unity gain with ≤3 dB roll-off. |
| Slew Rate | 2.4 V/µs - supports 1 VPP output at 380 kHz without distortion in unity-gain follower configuration. |
| Input Bias Current | 1 pA - minimizes voltage error in high-Z sensor circuits (e.g., pH electrodes, photodiode transimpedance amps). |
| Input Noise Voltage | 39 nV/√Hz @ 1 kHz - ensures <1 µV RMS integrated noise in 10 kHz bandwidth for precision DC-coupled sensing. |
| Output Swing | Rail-to-rail - delivers >99% of supply voltage range at 1 mA load, maximizing ADC input utilization in 12-bit+ systems. |
| Operating Temperature | −40°C to 125°C - meets AEC-Q100 Grade 1 requirements for under-hood and powertrain control modules. |
Pinout & Package
TLV272QDRG4Q1 is housed in an 8-pin SOIC (D) package with standard pin spacing (1.27 mm pitch), compatible with automated assembly and legacy PCB footprints. Thermal resistance θJA = 176°C/W enables 396 mW power dissipation at TA = 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Channel 1 output - drives loads up to ±100 mA; rail-to-rail swing supports full-scale ADC interfacing. |
| 2 | 1IN− | Inverting input - high-impedance CMOS node; sensitive to layout-induced leakage and EMI coupling. |
| 3 | 1IN+ | Non-inverting input - matched to Pin 2 for optimal common-mode rejection; requires symmetric trace routing. |
| 4 | GND | Analog ground reference - must connect to low-impedance ground plane; separate from digital ground if mixed-signal PCB. |
| 5 | VDD | Positive supply - decouple with 0.1 µF ceramic + 6.8 µF tantalum placed within 0.1 inch of pin. |
| 6 | 2IN+ | Channel 2 non-inverting input - electrically isolated from Channel 1; enables independent dual-sensor conditioning. |
| 7 | 2IN− | Channel 2 inverting input - identical electrical characteristics to Pin 2; supports differential or inverting configurations. |
| 8 | 2OUT | Channel 2 output - fully independent output stage; crosstalk < −40 dB at 1 MHz ensures channel isolation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC272QDRQ1 | Lower bandwidth (1.7 MHz), higher supply current (675 µA/ch), no rail-to-rail output (1.5 V headroom). | Not suitable for low-voltage (≤3.3 V) or full-scale ADC interfacing; acceptable for legacy 5 V designs with relaxed speed needs. | Select only if backward compatibility with existing TLC272 layouts is required and rail-to-rail output is unnecessary. |
| TLV2372QDRQ1 | Includes shutdown mode (IQ = 0.1 µA), same bandwidth/noise, but lower max supply (6 V). | Restricted to ≤6 V systems (e.g., infotainment); unsuitable for 12 V automotive subsystems or wide-input-range sensors. | Choose when ultra-low quiescent current in sleep mode is critical and supply voltage remains ≤6 V. |

FAQ
What is the maximum capacitive load the TLV272QDRG4Q1 can drive without external compensation?
The TLV272QDRG4Q1 maintains stable operation with capacitive loads up to 10 pF without external components. For loads exceeding 10 pF, a series resistor (RNULL ≥ 20 Ω) must be added between the output pin and the load to preserve ≥65° phase margin and prevent oscillation, as confirmed in the datasheet's Figure 16 and Application Information section.
Does TLV272QDRG4Q1 support true rail-to-rail input common-mode range?
No, TLV272QDRG4Q1 features rail-to-rail *output* only. Its input common-mode voltage range is specified as 0 V to VDD − 1.35 V - meaning it cannot accept signals within 1.35 V of the positive rail. This limitation is explicitly stated in the Recommended Operating Conditions table on page 4 of the datasheet.
What is the typical input offset voltage drift of TLV272QDRG4Q1 over temperature?
The TLV272QDRG4Q1 has a typical input offset voltage drift of 2 µV/°C, measured across the −40°C to 125°C automotive temperature range. This value is specified in the Electrical Characteristics table (page 5) under parameter αVIO, ensuring predictable DC error accumulation in precision temperature or current sensing applications.
Can TLV272QDRG4Q1 operate from a single 3.3 V supply in automotive applications?
Yes, TLV272QDRG4Q1 is fully specified for 3.3 V single-supply operation across −40°C to 125°C. Its 2.7 V minimum supply enables reliable function with Li-ion battery voltage sag, and its rail-to-rail output delivers >3.2 V swing at 1 mA load - ideal for interfacing with 3.3 V ADCs in automotive telematics and infotainment modules.
How does TLV272QDRG4Q1 compare to TLC272-Q1 in terms of power efficiency?
TLV272QDRG4Q1 consumes 550 µA per channel versus 675 µA for TLC272-Q1 - a 18.5% reduction - while delivering 76% higher bandwidth (3 MHz vs. 1.7 MHz). This efficiency gain enables longer battery life in always-on automotive modules without sacrificing signal fidelity or loop response time.
