Product details
Overview
OPA2316QDGKRQ1 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 OPA2316QDGKRQ1 datasheet, OPA2316QDGKRQ1 pinout, OPA2316QDGKRQ1 application, or OPA2316QDGKRQ1 equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade specifications, and real-world use cases in current sensing and battery management systems - all aligned with TI's SBOS841A production data sheet.
Technical Context
The OPA2316QDGKRQ1 implements a unity-gain stable, low-noise CMOS op-amp architecture optimized for 1.8-V to 5.5-V single- or dual-supply operation. Its rail-to-rail input stage supports common-mode voltages from (V–) – 0.2 V to (V+) + 0.2 V (at VS ≥ 2.5 V), while the rail-to-rail output delivers <30 mV from supply rails under 10-kΩ load at 5.5 V and full temperature range.
It integrates an internal RFI/EMI filter and exhibits no phase reversal during overdrive, with robust ±4-kV HBM ESD protection. Input bias current is ±5 pA typical, enabling accurate amplification of signals from megaohm-impedance sources such as thermistors and photodiodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 10 MHz - supports stable closed-loop operation up to 10 MHz with gain = 1, suitable for fast sensor signal buffering. |
| Quiescent Current / Channel | 400 µA - enables dual-amplifier operation on 1.8-V coin-cell or low-power MCU rails without compromising speed. |
| Input Voltage Noise Density | 11 nV/√Hz at 1 kHz - ensures minimal added noise in precision DC-coupled front-ends like current-sense amplifiers. |
| Input Bias Current | ±5 pA typical - preserves accuracy in high-impedance interfaces (e.g., pH sensors, piezoelectric transducers). |
| Offset Voltage | ±0.5 mV max - reduces initial error in unidirectional current sensing and battery voltage monitoring circuits. |
| Supply Voltage Range | 1.8 V to 5.5 V - operates directly from automotive 3.3-V or 5-V domains, or low-voltage microcontroller I/O rails. |
| Temperature Range | –40°C to +125°C ambient - certified for under-hood and cabin-mounted automotive ECUs per AEC-Q100 Grade 1. |
Pinout & Package
OPA2316QDGKRQ1 is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm, optimized for space-constrained automotive PCBs with thermal resistance RθJA = 186.6°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT A (Pin 1) | Output, Channel A | Amplified output of first op-amp; rail-to-rail swing supports direct interface to SAR ADC reference buffers. |
| –IN A (Pin 2) | Inverting Input, Channel A | High-impedance node for feedback networks; accepts signals down to (V–) – 0.2 V in single-supply configurations. |
| +IN A (Pin 3) | Noninverting Input, Channel A | Accepts rail-to-rail common-mode input; used for high-side current sensing with external resistor divider. |
| V– (Pin 4) | Negative Supply / Ground | Reference for single-supply operation (e.g., tied to GND); supports dual-supply operation when biased at negative potential. |
| +IN B (Pin 5) | Noninverting Input, Channel B | Independent input for second amplifier; enables dual-path signal conditioning (e.g., differential pair + reference buffer). |
| –IN B (Pin 6) | Inverting Input, Channel B | Configurable for inverting gain stages or active filtering; shares same low-input-bias-current advantage as Channel A. |
| OUT B (Pin 7) | Output, Channel B | Second independent output; usable for driving analog multiplexer inputs or redundant safety monitoring paths. |
| V+ (Pin 8) | Positive Supply | Accepts 1.8–5.5 V; internal regulation ensures stable performance across automotive battery transients (e.g., cold-crank 6 V, load-dump 40 V protected externally). |

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 integrated RFI filter, ±1.5-mV offset. | Suitable for cost-sensitive, lower-speed body electronics but not ADAS or precision current sensing. | Select when bandwidth <2 MHz suffices and BOM cost is prioritized over noise and EMI immunity. |
| TSV912IQDRQ1 | Higher bandwidth (8 MHz), higher IQ (820 µA/ch), rail-to-rail I/O, ±1.5-mV offset, no AEC-Q100 Grade 1 rating. | Used in industrial sensors; lacks automotive temperature validation and HBM/CDM certification for vehicle deployment. | Choose only for non-automotive designs requiring faster settling; avoid for production automotive ECUs. |

FAQ
What is the maximum operating temperature for OPA2316QDGKRQ1?
The OPA2316QDGKRQ1 is rated for ambient operating temperatures from –40°C to +125°C per AEC-Q100 Grade 1 qualification. This specification is validated across production lots and includes thermal derating guidance in TI's SBOS841A datasheet Section 6.3. The device maintains specified electrical performance within this range when mounted on JEDEC-standard PCBs with appropriate copper pour.
Does OPA2316QDGKRQ1 support single-supply operation?
Yes, OPA2316QDGKRQ1 fully supports 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 (at VS ≥ 2.5 V), and its rail-to-rail output swings within 30 mV of both supply rails under 10-kΩ load. This enables direct interfacing with 3.3-V or 5-V MCU ADCs without level-shifting circuitry.
Is OPA2316QDGKRQ1 pin-compatible with other devices in the OPAx316-Q1 family?
No - OPA2316QDGKRQ1 uses an 8-pin VSSOP (DGK) package, while OPA316-Q1 uses 5-pin SOT-23 and OPA4316-Q1 uses 14-pin TSSOP. Pin counts, footprints, and pin functions differ across the family. For example, OPA2316QDGKRQ1 has dedicated V+ and V– pins (Pins 8 and 4), whereas OPA316-Q1 places V+ on Pin 5 and V– on Pin 2. Migration requires PCB redesign.
What is the typical input bias current of OPA2316QDGKRQ1?
The typical input bias current of OPA2316QDGKRQ1 is ±5 pA at 25°C, with a maximum of ±15 nA over the full –40°C to +125°C temperature range. This ultra-low value is achieved via CMOS input stage design and enables accurate amplification of signals from high-impedance sources such as NTC thermistors, photodiodes, and electrochemical sensors without significant offset drift.
Does OPA2316QDGKRQ1 include ESD protection?
Yes, OPA2316QDGKRQ1 features robust on-chip ESD protection rated at ±4000 V HBM (Human Body Model) and ±750 V CDM (Charged Device Model), per AEC-Q100 test requirements. These ratings are verified during qualification and ensure reliable handling and operation in automotive manufacturing and field environments where static discharge events are common.
