Product details
Overview
TLV272QDRQ1 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 with 1 pA input bias current and 39 nV/√Hz input voltage noise-ideal for precision sensor signal conditioning in battery-powered ADAS front-end modules.
For engineers reviewing the TLV272QDRQ1 datasheet, TLV272QDRQ1 pinout, TLV272QDRQ1 application, or TLV272QDRQ1 equivalent, this page provides verified automotive-grade op-amp specifications, SOIC-8 package terminal mapping, real-world application context for low-voltage sensor interfaces, and validated alternative options for design flexibility under AEC-Q100 constraints.
Technical Context
The TLV272QDRQ1 employs CMOS input stage architecture enabling ultra-low input bias current (1 pA typ) and high input impedance, supporting direct interfacing with high-Z sensors such as piezoresistive pressure elements or thermopiles. Its rail-to-rail output stage operates down to 2.7 V single supply, maintaining ≥2.48 V high-level and ≤0.22 V low-level output swing at 1 mA load across full temperature range.
Internally compensated for unity-gain stability with 65° phase margin into 10-pF capacitive load, the device achieves 3-MHz bandwidth while consuming only 550 µA/ch-enabling high-speed signal conditioning without compromising micropower operation in always-on vehicle subsystems like occupancy detection or cabin air quality monitoring.
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 microcontroller I/O domains, and ±8-V split supplies in automotive body control units. |
| Bandwidth (UGBW) | 3 MHz - enables accurate amplification of ultrasonic parking assist signals up to 1.5 MHz with <0.1 dB gain flatness. |
| Slew Rate | 2.4 V/µs - ensures distortion-free reproduction of 1-Vpp pulses within 417 ns rise time for fast transient detection. |
| Input Bias Current | 1 pA (typ) - eliminates significant offset error when used with >10-MΩ source impedances in thermistor or RTD front ends. |
| Input Noise Voltage | 39 nV/√Hz - preserves SNR in low-level analog sensor paths such as MEMS microphone preamps or oxygen sensor interfaces. |
| Rail-to-Rail Output | VOH ≥ 2.55 V / VOL ≤ 0.15 V at VDD = 2.7 V, 1 mA - maximizes dynamic range in single-supply systems with tight headroom budgets. |
| Automotive Temp Range | −40°C to +125°C - qualified per AEC-Q100 Grade 1, enabling use in engine bay, transmission control, and under-hood sensing. |
Pinout & Package
TLV272QDRQ1 is housed in an 8-pin SOIC (D) package with standard JEDEC outline, 1.27-mm pitch, and exposed pad not present. Thermal resistance θJA = 176°C/W enables 396 mW power dissipation at TA = 25°C.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives downstream ADC input or active filter stage with rail-to-rail swing capability. |
| 2 | 1IN− | Inverting input of Channel 1 - connects to feedback network; high impedance minimizes loading on precision resistive dividers. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - accepts low-level sensor voltage (e.g., bridge output) with minimal input current error. |
| 4 | GND | Analog ground reference - must be tied to clean low-impedance ground plane to maintain PSRR >65 dB and CMRR >57 dB. |
| 5 | VDD | Positive supply rail - requires local 0.1-µF ceramic + 6.8-µF tantalum decoupling per TI layout guidelines. |
| 6 | 2IN+ | Non-inverting input of Channel 2 - enables dual-sensor differential measurement (e.g., dual-axis accelerometer interface). |
| 7 | 2IN− | Inverting input of Channel 2 - used for programmable gain configuration via external resistor network. |
| 8 | 2OUT | Output of Channel 2 - supports independent signal path for redundancy or multi-function sensor fusion architectures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372QDRQ1 | Includes shutdown mode (active-low EN pin); identical bandwidth, noise, and supply current but adds 1.5-µA shutdown quiescent draw. | Required where system-level power gating is mandated (e.g., ISO 26262 ASIL-B sleep modes). | Select TLV2372QDRQ1 only if hardware-controlled power-down is needed; otherwise TLV272QDRQ1 offers lower BOM count and simpler layout. |
| LM7332QMA/NOPB | Higher slew rate (10 V/µs), wider supply range (±15 V), but 2.3-mA/ch supply current and no AEC-Q100 qualification. | Suitable for non-automotive test equipment or industrial PLC analog I/O requiring higher speed and dual-supply operation. | Choose LM7332QMA/NOPB only for non-automotive designs needing >5-MHz bandwidth; TLV272QDRQ1 remains optimal for AEC-Q100-compliant cost-sensitive applications. |
Compared with TLV2372QDRQ1 and LM7332QMA/NOPB, TLV272QDRQ1 uniquely balances AEC-Q100 qualification, micropower consumption, rail-to-rail output, and SOIC-8 manufacturability-making it the preferred choice for volume automotive sensor signal chains where reliability, power, and footprint are jointly constrained.

FAQ
What is the maximum capacitive load the TLV272QDRQ1 can drive without instability?
The TLV272QDRQ1 maintains ≥65° phase margin with up to 10 pF capacitive load at unity gain. For loads exceeding 10 pF, TI recommends adding a series nulling resistor (RNULL ≥20 Ω) between the output and load to preserve stability-verified in Figure 16 of the SGLS275A datasheet. This applies directly to TLV272QDRQ1 in SOIC-8 configuration.
Does TLV272QDRQ1 support split-supply operation, and what are the limits?
Yes, TLV272QDRQ1 supports split-supply operation from ±1.35 V to ±8 V, as specified in the recommended operating conditions table. This enables bipolar signal handling in automotive audio preamps or active suspension sensor interfaces while maintaining rail-to-rail output swing relative to each supply rail.
Is TLV272QDRQ1 pin-compatible with legacy TLC272 devices?
No-TLV272QDRQ1 uses standard SOIC-8 pinout (1OUT, 1IN−, 1IN+, GND, VDD, 2IN+, 2IN−, 2OUT), whereas TLC272 has identical pin assignment but differs in input offset voltage (7 mV max vs 5 mV), bandwidth (1.7 MHz vs 3 MHz), and supply current (675 µA vs 550 µA). Layout reuse is possible, but electrical validation is required.
What is the typical input offset voltage drift of TLV272QDRQ1 over temperature?
The TLV272QDRQ1 exhibits a typical input offset voltage drift of 2 µV/°C, measured across −40°C to 125°C. This low drift ensures <150-µV total offset variation over full automotive temperature range-critical for high-accuracy bridge sensor applications like brake pressure monitoring.
Can TLV272QDRQ1 operate reliably at 2.7-V supply with full rail-to-rail output swing?
Yes-TLV272QDRQ1 guarantees rail-to-rail output swing at 2.7-V supply: VOH ≥ 2.48 V and VOL ≤ 0.22 V at 1-mA load across −40°C to 125°C. This enables direct interfacing with 2.7–3.6-V microcontrollers and low-voltage ADCs without level-shifting circuitry.
