Product details
Overview
OPA316QDBVTQ1 from Texas Instruments is a single-channel, rail-to-rail input/output, automotive-grade CMOS operational amplifier optimized for low-voltage operation (1.8 V to 5.5 V). It delivers 10 MHz unity-gain bandwidth, 400 µA quiescent current per channel, 11 nV/√Hz input voltage noise at 1 kHz, ±0.5 mV offset voltage, and ±5 pA input bias current - enabling precision signal conditioning in battery-powered ADAS sensors and current-sensing circuits.
For engineers reviewing the OPA316QDBVTQ1 datasheet, OPA316QDBVTQ1 pinout, OPA316QDBVTQ1 application, or OPA316QDBVTQ1 equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade specifications (AEC-Q100 Grade 1), and real-world application mappings - all grounded in TI's SBOS841A production data sheet.
Technical Context
The OPA316QDBVTQ1 employs a CMOS input stage with ultra-low input bias current (±5 pA typical) and integrated RFI/EMI filtering, supporting high-impedance sensor interfaces without signal degradation. Its unity-gain stable architecture ensures robust performance in gain-of-1 configurations common in transimpedance amplifiers and voltage followers.
Designed for automotive environments, it operates across –40°C to +125°C ambient temperature, features ±4-kV HBM ESD protection, and maintains rail-to-rail output swing within 15 mV of supply rails at 1.8 V (10 kΩ load), enabling full dynamic range utilization in low-voltage ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 10 MHz - supports fast signal acquisition in ADAS front-end amplification and active filter stages. |
| Quiescent Current | 400 µA/ch - enables multi-channel sensing in power-constrained automotive modules without thermal penalty. |
| Input Voltage Noise | 11 nV/√Hz at 1 kHz - preserves SNR in low-level sensor signals such as thermopile or strain gauge outputs. |
| Input Bias Current | ±5 pA - minimizes voltage error in megaohm-source applications like photodiode transimpedance amplifiers. |
| Offset Voltage | ±0.5 mV (typ) - reduces initial DC error in precision current-sensing shunt amplifier designs. |
| Supply Range | 1.8 V to 5.5 V - interoperates with modern automotive MCUs and ASICs operating at 1.8 V, 3.3 V, or 5 V rails. |
| CMRR | 86 dB (min) at 1.8 V - rejects common-mode noise in noisy vehicle electrical systems during battery monitoring. |
Pinout & Package
OPA316QDBVTQ1 is housed in a 5-pin SOT-23 (DBV) package measuring 1.60 mm × 2.90 mm, optimized for space-constrained automotive PCB layouts and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Output | Amplified signal source capable of rail-to-rail swing; drives 10 kΩ loads within 15 mV of supply rails at 1.8 V. |
| 2 - V– | Negative Supply / Ground | Reference node for single-supply operation (e.g., connected to GND); supports true rail-to-rail input common-mode range down to V– – 0.2 V. |
| 3 - +IN | Noninverting Input | High-impedance CMOS node (ZIC = 10¹¹ Ω || 4 pF); accepts signals from high-Z sources without loading. |
| 4 - –IN | Inverting Input | Differential input node; used in inverting amplifier, transimpedance, or differential receiver configurations. |
| 5 - V+ | Positive Supply | Power input supporting 1.8–5.5 V operation; internal regulation enables stable performance across wide supply variation. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM7321QDRQ1 | Higher IQ (1.3 mA), wider supply (2.7–36 V), no integrated RFI filter | Better suited for higher-voltage industrial sensors; less optimal for ultra-low-power 1.8-V automotive nodes | Select when >10-MHz bandwidth and high-voltage tolerance outweigh quiescent current constraints. |
| TSV911QDBVRQ1 | Lower bandwidth (8 MHz), lower noise (10.5 nV/√Hz), same AEC-Q100 Grade 1 rating | Optimized for cost-sensitive body electronics where 10-MHz headroom is unnecessary | Choose for non-critical timing applications where 2-MHz margin reduction is acceptable for BOM cost savings. |

FAQ
What is the maximum operating temperature for OPA316QDBVTQ1?
The OPA316QDBVTQ1 is qualified for AEC-Q100 Grade 1 operation, supporting continuous ambient temperatures from –40°C to +125°C. This rating is validated per TI's SBOS841A production data sheet and applies across its full 1.8–5.5 V supply range - making it suitable for under-hood and cabin-mounted automotive modules.
Does OPA316QDBVTQ1 support single-supply operation?
Yes, OPA316QDBVTQ1 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 at 1.8 V with a 10-kΩ load - enabling direct interfacing with 1.8-V microcontrollers and ADCs.
Is OPA316QDBVTQ1 pin-compatible with other devices in the OPAx316-Q1 family?
No - OPA316QDBVTQ1 (SOT-23, 5-pin) is not pin-compatible with OPA2316-Q1 (VSSOP, 8-pin) or OPA4316-Q1 (TSSOP, 14-pin). Each variant has distinct pin counts, layouts, and terminal assignments. The OPA316QDBVTQ1 pinout is defined in TI's SBOS841A Pin Configuration section for DBV package only.
What packaging format is used for OPA316QDBVTQ1?
OPA316QDBVTQ1 is supplied in a 5-pin SOT-23 (DBV) package with nominal dimensions of 1.60 mm × 2.90 mm. This surface-mount package is RoHS-compliant, lead-free, and qualified for automotive reflow profiles per J-STD-020 - confirmed in TI's SBOS841A Device Information table.
How does the integrated RFI-EMI filter in OPA316QDBVTQ1 improve system robustness?
The integrated RFI-EMI filter in OPA316QDBVTQ1 attenuates high-frequency interference (e.g., from AM/FM radio bands, ignition pulses, or switch-mode power supplies) before it reaches the input stage - eliminating need for external RC filters. This improves signal integrity in electrically noisy automotive environments while reducing PCB area and BOM count.
