Product details
Overview
TLC2272QPWRQ1 from Texas Instruments is a dual, rail-to-rail output, automotive-grade LinCMOS™ operational amplifier qualified to AEC-Q100 Grade 1 (–40°C to 125°C), featuring 9 nV/√Hz input voltage noise at 1 kHz, 3.6 V/μs slew rate, and 950 μV maximum input offset voltage at 25°C. It operates from ±2.2 V to ±8 V supplies and delivers rail-to-rail output swing for high dynamic range in body control modules and battery management systems.
For engineers reviewing the TLC2272QPWRQ1 datasheet, TLC2272QPWRQ1 pinout, TLC2272QPWRQ1 application, or TLC2272QPWRQ1 equivalent, this page provides verified functional safety documentation support, confirmed SOIC-8 and TSSOP-8 package compatibility, validated rail-to-rail output behavior across single- and split-supply configurations, and precise electrical specs per TI SGLS007G Rev G (August 2022).
Technical Context
The TLC2272QPWRQ1 implements a LinCMOS™ input stage with ultra-low input bias current (1 pA typical) and high input impedance (>10¹² Ω), enabling precision signal conditioning of high-impedance sources like piezoelectric transducers. Its rail-to-rail output stage supports full-swing operation into ADC interfaces without level-shifting circuitry.
It features internal compensation for unity-gain stability, 2.2 MHz gain-bandwidth product, and phase margin ≥50° with 100 pF load - optimized for automotive sensor amplification and closed-loop motor control feedback paths where low noise, wide common-mode range (down to VDD−), and robust ESD performance (HBM ±2000 V) are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports dual-supply automotive systems (e.g., ±5 V) and single-supply 5 V rails without external level shifters. |
| Input Offset Voltage (max) | 950 μV at TA = 25°C - enables accurate DC-coupled amplification in engine control unit (ECU) analog front-ends. |
| Slew Rate | 3.6 V/μs typical - sufficient for fast transient response in electric power steering position feedback loops. |
| Input Voltage Noise | 9 nV/√Hz at f = 1 kHz - two times lower than competitive CMOS op amps, reducing noise floor in car audio preamplifiers. |
| Common-Mode Input Range | Includes negative rail (VDD−) - allows direct sensing of ground-referenced signals in battery shunt monitoring. |
| Output Swing | Rail-to-rail - delivers full 0–5 V or ±4.9 V output span into 10 kΩ loads, maximizing ADC utilization in instrument clusters. |
| ESD Rating (HBM) | ±2000 V - meets AEC-Q100-002 Class 2 for robustness in automotive assembly and field environments. |
Pinout & Package
TLC2272QPWRQ1 is available in an 8-pin TSSOP (PW) package with nominal body size 3.00 mm × 4.40 mm and standard JEDEC MO-153 footprint. Thermal resistance RθJA = 175.8°C/W enables operation up to 125°C ambient in constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN+ | Noninverting input, Channel 1 | High-impedance node (10¹² Ω) for precision sensor signal routing; accepts common-mode down to VDD−. |
| 1IN– | Inverting input, Channel 1 | Differential pair input; matched with 1IN+ for <950 μV offset in closed-loop configurations. |
| 1OUT | Output, Channel 1 | Rail-to-rail capable; drives 10 kΩ loads to within 10 mV of supply rails at ±20 μA. |
| 2IN+ | Noninverting input, Channel 2 | Independent high-Z input for dual-channel applications such as differential current sensing in DC/DC converters. |
| 2IN– | Inverting input, Channel 2 | Matched pair with 2IN+; supports identical offset and noise performance as Channel 1. |
| 2OUT | Output, Channel 2 | Full rail-to-rail swing; usable for redundant signal paths or dual-sensor conditioning in transmission control units. |
| VDD+ | Positive supply | Highest potential supply rail; must be ≥ |VDD−| + 0.5 V for proper biasing of LinCMOS™ input stage. |
| VDD– | Negative supply | Lowest potential rail; defines reference for common-mode range and output swing limits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432-Q1 | Higher output drive (±50 mA vs ±50 mA short-circuit, but higher sustained current), wider input voltage range (up to VDD− + 0.2 V to VDD+ − 1.5 V). | Better suited for driving capacitive loads >1 nF or low-impedance DAC buffers in inverter gate drivers. | Select TLV2432-Q1 when output current >20 mA or input common-mode beyond VDD− is required; not pin-compatible with TLC2272QPWRQ1. |
| LM7332-Q1 | Higher slew rate (10 V/μs), higher GBW (21 MHz), but higher input offset (1.8 mV max) and noise (15 nV/√Hz). | Preferred for high-speed motor control loop compensation or active filter stages requiring >5 MHz bandwidth. | Choose LM7332-Q1 for speed-critical feedback paths; TLC2272QPWRQ1 remains optimal for low-noise, low-offset sensor conditioning where 2.2 MHz suffices. |
Compared with TLV2432-Q1 and LM7332-Q1, TLC2272QPWRQ1 offers superior noise performance and lower input offset voltage while maintaining AEC-Q100 Grade 1 qualification - making it the preferred choice for precision analog signal chains in body electronics and battery monitoring where DC accuracy and low-frequency noise dominate design requirements.

FAQ
What is the maximum operating temperature range for the TLC2272QPWRQ1?
The TLC2272QPWRQ1 is qualified to AEC-Q100 Grade 1 with an operating free-air temperature range of –40°C to 125°C. This rating is fully characterized per TI SGLS007G Rev G, including electrical parameters such as input offset voltage, slew rate, and CMRR across the full range. The device maintains rail-to-rail output functionality and 950 μV max VIO specification at 25°C, with derated performance defined in Section 6.5 and 6.6 of the datasheet.
Does the TLC2272QPWRQ1 support single-supply operation?
Yes, the TLC2272QPWRQ1 is fully specified for single-supply operation from 4.4 V to 16 V (VDD = 5 V typical). Its common-mode input voltage range extends to the negative rail (VDD−), and output swings rail-to-rail - enabling direct interfacing with 3.3 V or 5 V microcontroller ADCs without level-shifting circuitry. The datasheet confirms performance in both single- and split-supply configurations in Sections 6.5 and 6.7.
Is the TLC2272QPWRQ1 pin-compatible with the standard TLC2272 series?
No - the TLC2272QPWRQ1 is the automotive-qualified variant with enhanced reliability screening and functional safety documentation, but shares identical pinout and electrical behavior with the commercial TLC2272PWR. Pin compatibility is confirmed in Figure 5-1 and Table 5-1 of SGLS007G, covering both SOIC-8 (D) and TSSOP-8 (PW) packages. However, thermal and ESD ratings differ per AEC-Q100 requirements.
What functional safety documentation is available for the TLC2272QPWRQ1?
Texas Instruments provides functional safety documentation for the TLC2272QPWRQ1 including FIT rate data, failure mode effect analysis (FMEA), and diagnostic coverage reports - all accessible via TI's functional safety resource center. These materials support ISO 26262 ASIL-B system development and are explicitly referenced in the "Features" section of the SGLS007G datasheet under "Functional Safety-Capable".
Can the TLC2272QPWRQ1 drive capacitive loads without oscillation?
The TLC2272QPWRQ1 is unity-gain stable with a phase margin ≥50° and gain margin ≥10 dB when driving 100 pF loads (Section 6.5/6.6), but becomes unstable with >500 pF capacitive loads unless isolated with a series resistor. For loads exceeding 100 pF, TI recommends adding a 10–100 Ω isolation resistor between the output and capacitor, as detailed in Section 8.2 ("Typical Application") and Figure 8-2 of SGLS007G.
