Product details
Overview
OPA2316QDGKQ1 from Texas Instruments is a dual-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 and body electronics sensors.
For engineers reviewing the OPA2316QDGKQ1 datasheet, OPA2316QDGKQ1 pinout, OPA2316QDGKQ1 application, or OPA2316QDGKQ1 equivalent, this page provides verified technical context, validated pin functions, automotive-grade reliability data, and real-world design implications - not generic op-amp summaries.
Technical Context
The OPA2316QDGKQ1 employs a CMOS input stage with ±5 pA typical input bias current, supporting high-impedance sensor interfaces without significant DC error. Its unity-gain stable architecture includes integrated RFI/EMI filtering and no phase reversal under overdrive - critical for robust operation in noisy automotive environments.
It operates from 1.8 V to 5.5 V total supply, achieving rail-to-rail output swing within 15 mV of rails (at 1.8 V, RL = 10 kΩ) and maintaining 94 dB open-loop gain at 1.8 V. Input common-mode range extends to (V–) – 0.2 V, enabling single-supply sensing near ground.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 10 MHz - supports fast closed-loop response in active filters and sensor amplifiers up to ~1 MHz usable bandwidth. |
| Quiescent Current / ch | 400 µA - enables dual-channel precision amplification in 1.8-V battery systems with sub-1-mA total supply draw. |
| Input Voltage Noise | 11 nV/√Hz at 1 kHz - preserves SNR in low-level analog front-ends like thermistor or strain gauge interfaces. |
| Input Bias Current | ±5 pA - minimizes voltage error across >1 MΩ source impedances, e.g., pH electrodes or photodiode TIA feedback networks. |
| Offset Voltage | ±0.5 mV (typ) - ensures ≤0.5% gain error in 100-mV full-scale current-sense applications without trimming. |
| Supply Range | 1.8 V to 5.5 V - interoperates with modern low-voltage MCUs and ASIL-B domain controllers without level-shifting. |
| CMRR | 86 dB (min, 1.8 V) - rejects common-mode transients on chassis-ground-referenced signals in vehicle body modules. |
Pinout & Package
OPA2316QDGKQ1 is housed in an 8-pin VSSOP package (3.00 mm × 3.00 mm), optimized for space-constrained automotive PCBs and compatible with standard surface-mount reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT A (Pin 1) | Output, Channel A | Delivers rail-to-rail buffered signal; drives 10-kΩ loads to within 15 mV of rails at 1.8 V. |
| –IN A (Pin 2) | Inverting Input, Channel A | Accepts differential input down to (V–) – 0.2 V; enables single-supply inverting configurations. |
| +IN A (Pin 3) | Noninverting Input, Channel A | High-impedance node (10¹⁶ Ω || pF); minimal loading on high-Z sources like capacitive sensors. |
| V– (Pin 4) | Negative Supply / Ground | Reference for single-supply operation; must be connected directly to low-impedance ground plane. |
| +IN B (Pin 5) | Noninverting Input, Channel B | Independent input for second signal path; shares same ESD and noise performance as Channel A. |
| –IN B (Pin 6) | Inverting Input, Channel B | Supports dual-channel differential sensing (e.g., two-phase motor current monitoring). |
| OUT B (Pin 7) | Output, Channel B | Simultaneous dual-output capability eliminates need for discrete duplication in redundant safety circuits. |
| V+ (Pin 8) | Positive Supply | Accepts 1.8–5.5 V; internal regulation ensures stable biasing across automotive battery variation (9–16 V with LDO). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated operation from –40°C to +125°C ambient, meeting ASIL-B system requirements for body electronics and ADAS subsystems. |
| Integrated RFI/EMI filter | Rejects >30 dB of 100-MHz–2-GHz RF interference - eliminates external ferrite beads in infotainment and radar proximity sensor paths. |
| No phase reversal on overdrive | Prevents latch-up or uncontrolled output slewing during input transients (e.g., load dump or ESD events), enhancing functional safety. |
| Rail-to-rail I/O | Maximizes dynamic range in 1.8-V systems: full 0–1.8 V output swing preserves 99% of ADC input range without level-shifting. |
| HBM ESD rating: ±4 kV | Withstands handling and assembly stress without protection diodes - reduces BOM count in production-line test fixtures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358QDRQ1 | Lower bandwidth (1 MHz), higher IQ (150 µA/ch), no RFI filter, ±1.5-mV offset | Suitable for cost-sensitive, low-speed body control (e.g., window lift detection), not for high-fidelity sensor paths | Choose when bandwidth <2 MHz suffices and BOM cost dominates over signal integrity. |
| TSV912IQDRQ1 | Higher noise (24 nV/√Hz), wider offset range (±1.5 mV), same 10-MHz GBW and AEC-Q100 Grade 1 | Acceptable for mid-tier ADAS subsystems where SNR margin >15 dB is available | Choose if existing layout uses SOIC-8 and thermal budget allows higher dissipation (1.2× OPA2316QDGKQ1). |

FAQ
What is the maximum operating temperature for OPA2316QDGKQ1?
The OPA2316QDGKQ1 is qualified for continuous operation from –40°C to +125°C ambient temperature (AEC-Q100 Grade 1). This rating is validated across all electrical parameters in the datasheet, including offset drift, CMRR, and open-loop gain - ensuring reliable performance in engine bay and under-hood applications where junction temperatures may exceed 130°C.
Does OPA2316QDGKQ1 require external compensation for unity-gain stability?
No, OPA2316QDGKQ1 is internally compensated for unity-gain stability. The datasheet confirms stable operation with ≥60° phase margin at G = +1, eliminating the need for external compensation components. This simplifies layout in space-constrained automotive modules and avoids tuning errors in production.
Can OPA2316QDGKQ1 operate from a single 1.8-V supply?
Yes, OPA2316QDGKQ1 is fully specified for 1.8-V single-supply operation. Its rail-to-rail input accepts common-mode voltages from (V–) – 0.2 V to (V+) + 0.2 V, and its output swings to within 15 mV of both rails under 10-kΩ load - enabling direct interfacing with 1.8-V ADCs and low-voltage microcontrollers without level-shifting circuitry.
What is the ESD robustness of OPA2316QDGKQ1?
OPA2316QDGKQ1 features ±4-kV HBM (Human Body Model) and ±750-V CDM (Charged Device Model) ESD ratings per AEC-Q100. These values are measured and certified - not estimated - and reflect hardened I/O structures that eliminate the need for external TVS diodes in most automotive board-level ESD protection schemes.
How does the integrated RFI filter in OPA2316QDGKQ1 improve system performance?
The integrated RFI filter in OPA2316QDGKQ1 attenuates >30 dB of RF energy above 100 MHz, preventing demodulation of cellular, Wi-Fi, and radar signals into the baseband. In practice, this eliminates audible noise in audio amplifiers and measurement errors in current-sense circuits exposed to 2.4-GHz ISM band emissions - verified in TI's EMC test reports for automotive environments.
