Product details
Overview
OPA4316QPWRQ1 from Texas Instruments is a quad-channel, rail-to-rail input/output, low-voltage CMOS operational amplifier qualified for automotive applications (AEC-Q100 Grade 1, –40°C to +125°C). It delivers 10-MHz unity-gain bandwidth, 400 µA per channel quiescent current, and 11 nV/√Hz input voltage noise at 1 kHz - enabling high-precision signal conditioning in battery-powered ADAS sensors and body electronics.
For engineers reviewing the OPA4316QPWRQ1 datasheet, OPA4316QPWRQ1 pinout, OPA4316QPWRQ1 application, or OPA4316QPWRQ1 equivalent, key selection criteria include its rail-to-rail operation down to 1.8 V supply, ±0.5 mV max input offset voltage, integrated RFI-EMI filter, and TSSOP-14 automotive-grade packaging with verified thermal performance (RθJA = 117.2°C/W).
Technical Context
The OPA4316QPWRQ1 employs a CMOS input stage with ±5 pA typical input bias current, supporting high-impedance sensor interfaces such as thermistors and photodiodes. Its unity-gain stable architecture features internal compensation and no phase reversal under overdrive - critical for reliable operation in closed-loop current sensing and battery management feedback paths.
Designed for low-voltage automotive systems, it operates across 1.8 V to 5.5 V total supply range (±0.9 V to ±2.75 V), with rail-to-rail output swing within 15 mV of rails (at 1.8 V, 10-kΩ load) and 6 V/µs slew rate - balancing speed, power efficiency, and DC precision in space-constrained ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 10 MHz - supports stable amplification of signals up to audio and ultrasonic frequencies in sensor front-ends. |
| Quiescent Current / Channel | 400 µA - enables four independent amplifiers to operate continuously on <2 mA total supply current, ideal for always-on vehicle modules. |
| Input Offset Voltage | ±0.5 mV (max at 25°C) - ensures ≤0.5% error in 1-V full-scale current-sense applications without trimming. |
| Input Voltage Noise Density | 11 nV/√Hz at 1 kHz - preserves SNR in low-level analog signal chains like piezoelectric knock sensors. |
| Supply Voltage Range | 1.8 V to 5.5 V - compatible with 2S Li-ion battery packs and 3.3-V/5-V automotive domain controllers. |
| CMRR / PSRR | ≥70 dB (min, –40°C to +125°C) - rejects common-mode transients from motor drives and power supply ripple in body control units. |
| Output Swing (1.8 V) | Within 15 mV of rails (10-kΩ load) - maximizes dynamic range in single-supply 1.8-V microcontroller ADC interfaces. |
Pinout & Package
OPA4316QPWRQ1 is housed in a 14-pin TSSOP (PW) package measuring 4.40 mm × 5.00 mm, optimized for automated assembly and thermal dissipation in automotive PCBs (RθJA = 117.2°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A/B/C/D | Amplifier outputs - each capable of driving 10-kΩ loads within 15–120 mV of supply rails depending on voltage and load. |
| 2, 6, 9, 13 | –IN A/B/C/D | Inverting inputs - high-impedance CMOS nodes (ZID = 1016 Ω || 2 pF) for precision differential gain stages. |
| 3, 5, 10, 12 | +IN A/B/C/D | Noninverting inputs - rail-to-rail common-mode range supports direct connection to resistive divider networks. |
| 4 | V+ | Positive supply terminal - accepts 1.8–5.5 V; decoupling capacitor required for EMI immunity. |
| 11 | V– | Negative supply or ground - enables single- or dual-supply operation; internally referenced for input stage biasing. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation with 4-kV HBM ESD protection - meets automotive reliability requirements without derating. |
| Rail-to-rail I/O | Enables full utilization of 1.8-V ADC reference range in battery monitoring ICs, eliminating level-shifting circuitry. |
| Integrated RFI-EMI filter | Rejects >60 dB of 100-MHz+ RF interference - critical for compliance in infotainment and radar proximity sensors. |
| No phase reversal on overdrive | Prevents latch-up and uncontrolled output saturation during transient input excursions in motor current feedback loops. |
| Low input bias current (±5 pA) | Minimizes voltage error in megaohm-source applications like humidity and gas sensors, reducing calibration drift. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV339QDRQ1 | Quad comparator (not op amp); 1.8-V min supply; 300-ns propagation delay; no linear amplification capability. | Suitable only for threshold detection (e.g., overvoltage flag), not for analog signal conditioning or closed-loop control. | Select only when discrete voltage comparison-not amplification-is required; cannot replace OPA4316QPWRQ1 in gain or buffering roles. |
| TSV914IQDT | Quad rail-to-rail op amp; 8-MHz GBW; 1.15-mA/ch IQ; ±1.5-mV VOS; non-automotive grade (no AEC-Q100). | Lacks automotive qualification and extended temperature support; higher power consumption limits use in always-on modules. | Consider for cost-sensitive industrial designs where AEC-Q100 is not mandated; verify thermal margin due to 2.9× higher IQ. |
Compared with LMV339QDRQ1 and TSV914IQDT, the OPA4316QPWRQ1 uniquely combines automotive qualification, 10-MHz bandwidth, and ultra-low 400-µA/ch quiescent current - making it the only option among the three suitable for precision, low-power, safety-compliant analog signal chains in modern vehicle ECUs.

FAQ
What is the maximum operating temperature range for the OPA4316QPWRQ1?
The OPA4316QPWRQ1 is qualified per AEC-Q100 Grade 1 with a specified ambient operating temperature range of –40°C to +125°C. This rating is validated across all electrical parameters in the datasheet, including offset voltage drift (±10 µV/°C max), open-loop gain (≥86 dB at 125°C), and quiescent current (≤500 µA/ch), ensuring robust performance in engine bay and under-hood applications.
Does the OPA4316QPWRQ1 support single-supply operation?
Yes, the OPA4316QPWRQ1 supports true single-supply operation from 1.8 V to 5.5 V. Its rail-to-rail input stage accepts common-mode voltages from (V–) – 0.2 V to (V+) + 0.2 V, and its rail-to-rail output swings within 15 mV of either rail under light load - enabling direct interfacing with 1.8-V or 3.3-V microcontrollers without level-shifting components.
What is the purpose of the internal RFI-EMI filter in the OPA4316QPWRQ1?
The internal RFI-EMI filter in the OPA4316QPWRQ1 attenuates high-frequency electromagnetic interference above 100 MHz by >60 dB, as measured in EMIRR testing. This feature prevents rectification of RF signals at the input stage - a known cause of DC offset shifts and erratic behavior in automotive environments near radar, cellular, and Bluetooth transmitters.
Can the OPA4316QPWRQ1 drive capacitive loads without instability?
The OPA4316QPWRQ1 is unity-gain stable but exhibits increasing overshoot with capacitive loads: typical overshoot is <10% at 100 pF and rises to ~70% at 300 pF (per Figure 24). For loads >100 pF, TI recommends adding a series resistor (e.g., 10–50 Ω) between amplifier output and capacitance to maintain phase margin and prevent ringing in LED driver or filter applications.
How does the OPA4316QPWRQ1 handle input overdrive conditions?
The OPA4316QPWRQ1 features no phase reversal during input overdrive - a critical reliability enhancement confirmed in Figure 26 of the datasheet. When inputs exceed the common-mode range, the output remains predictable and recovers cleanly (tOR = 0.3 µs), avoiding latch-up or uncontrolled saturation that could disrupt feedback loops in motor control or battery protection circuits.
