Product details
Overview
OPA2836QDGKRQ1 from Texas Instruments is a dual-channel, automotive-grade, rail-to-rail output, negative-rail input voltage-feedback operational amplifier. It delivers 205 MHz bandwidth, 560 V/µs slew rate, and 1 mA quiescent current per channel at 5 V supply, enabling high-fidelity signal conditioning in battery-powered automotive sensor interfaces and ADC drivers.
For engineers reviewing the OPA2836QDGKRQ1 datasheet, OPA2836QDGKRQ1 pinout, OPA2836QDGKRQ1 application, or OPA2836QDGKRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (–40°C to +125°C), –130 dBc THD at 1 kHz, 4.6 nV/√Hz input voltage noise, and dual-VSSOP-8 package compatibility with space-constrained automotive control units.
Technical Context
The OPA2836QDGKRQ1 employs a voltage-feedback architecture optimized for unity-gain stability across 2.5 V to 5.5 V supplies. Its negative-rail input stage supports common-mode voltages down to –0.2 V (vs VS–), while rail-to-rail output delivers >4.75 V swing at 5 V supply into 1 kΩ load.
Each amplifier channel features independent power-down capability (0.5 µA typ), 116 dB CMRR, and 100+ dB PSRR up to 100 kHz-enabling robust performance in noisy automotive power domains without external filtering overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 205 MHz at G = 1, 5 V supply - enables accurate amplification of multi-MHz sensor signals without phase lag. |
| Slew Rate | 560 V/µs (rise), 580 V/µs (fall) - supports fast transient response for pulse-based automotive diagnostics. |
| THD | –130 dBc at 1 kHz, 1 VRMS - ensures minimal harmonic distortion in precision audio and SAR ADC front-ends. |
| Input Noise | 4.6 nV/√Hz at 100 kHz - preserves SNR in low-level sensor signal chains like piezoelectric knock detection. |
| Quiescent Current | 1.0 mA per channel (typ) at 5 V - extends battery life in always-on vehicle subsystems such as telematics wake-up receivers. |
| Operating Temp | –40°C to +125°C ambient - meets full automotive Grade 1 thermal requirements for engine bay and ADAS ECU deployment. |
| Output Drive | ±50 mA (min) - directly drives 1 kΩ loads or 100 pF capacitive cables without external buffers in camera module interfaces. |
Pinout & Package
VSSOP-8 (DGK) package: 3.00 mm × 3.00 mm body, 0.65 mm pitch, exposed pad optional for thermal relief. Compatible with standard 0.5-mm stencil apertures and reflow profiles per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT1 | Amplifier 1 output | Delivers rail-to-rail output swing; requires local 0.1 µF bypass to VS– for stability in high-frequency closed-loop configurations. |
| VIN1– | Amplifier 1 inverting input | High-impedance node; sensitive to PCB leakage-must be routed away from digital traces and guarded in precision sensor paths. |
| VIN1+ | Amplifier 1 noninverting input | Accepts common-mode voltages from –0.2 V to +3.9 V (5 V supply); enables single-supply interfacing with grounded sensors. |
| VS– | Negative power supply | Reference for both inputs and outputs; must be low-impedance with dedicated ground plane connection to minimize PSRR degradation. |
| VIN2+ | Amplifier 2 noninverting input | Independent channel input; shares same electrical specs as VIN1+-supports dual-sensor differential pair buffering. |
| VIN2– | Amplifier 2 inverting input | Matches VIN1– characteristics; channel-to-channel crosstalk < –120 dB at 10 kHz enables simultaneous high-gain analog processing. |
| VOUT2 | Amplifier 2 output | Electrically isolated from VOUT1; supports independent gain/feedback networks for multi-path signal conditioning. |
| VS+ | Positive power supply | Accepts 2.5 V to 5.5 V; internal regulation maintains consistent biasing across supply variation-critical for stop-start vehicle operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 | Qualified for –40°C to +125°C ambient operation with HBM ±6 kV and CDM ±1 kV ESD robustness-meets automotive safety-critical reliability standards. |
| Rail-to-Rail Output | Swings within 100 mV of VS+ and 50 mV of VS– at 5 V supply-maximizes dynamic range for 12-bit+ ADCs without level-shifting circuitry. |
| Negative-Rail Input | Operates with input common-mode down to –0.2 V relative to VS–-enables direct interface with grounded thermocouples or shunt-based current monitors. |
| Power-Down Mode | Reduces quiescent current to 0.5 µA per channel-ideal for duty-cycled sensor nodes in tire pressure monitoring systems (TPMS). |
| Low Distortion | HD2/HD3 ≤ –85 dBc/–105 dBc at 1 MHz (2 VPP)-preserves signal integrity in wideband radar IF amplifiers and ultrasonic parking assist receivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2836 | Same core architecture and pinout, but commercial-grade (–40°C to +85°C) and not AEC-Q100 qualified. | Lacks automotive temperature range and ESD robustness-unsuitable for under-hood or safety-critical modules. | Select only for non-automotive industrial or consumer test equipment where Grade 1 qualification is unnecessary. |
| LMH6619 | 140 MHz bandwidth, 45 V/µs slew rate, 1.25 mA IQ, and rail-to-rail input/output-but no negative-rail input capability. | Cannot interface directly with grounded sensors; requires level-shifting for single-supply designs with sub-V common-mode signals. | Prefer when rail-to-rail input is mandatory and bandwidth requirements are ≤140 MHz; verify input common-mode range compatibility. |
Compared with OPA2836QDGKRQ1, the OPA2836 lacks automotive qualification and extended temperature support, while the LMH6619 trades bandwidth and input flexibility for higher power and missing negative-rail input-making the OPA2836QDGKRQ1 uniquely suited for compact, low-power, AEC-Q100-compliant dual-channel sensor interfaces.

FAQ
What is the maximum operating supply voltage for the OPA2836QDGKRQ1?
The OPA2836QDGKRQ1 supports a specified operating voltage range of 2.5 V to 5.5 V on a single supply (or ±1.25 V to ±2.75 V dual supply). Absolute maximum ratings limit VS+ to VS– + 5.5 V; exceeding this risks permanent damage. Operation at 5.5 V is validated across –40°C to +125°C and maintains all key specifications including 205 MHz bandwidth and 1 mA quiescent current per channel.
Does the OPA2836QDGKRQ1 support true rail-to-rail input operation?
No-the OPA2836QDGKRQ1 features rail-to-rail *output* and *negative-rail input*, but not rail-to-rail input. Its input common-mode range extends from –0.2 V to +3.9 V at 5 V supply, meaning it accepts voltages down to 0.2 V below VS– but only up to 1.1 V below VS+. This enables direct interfacing with grounded sensors while requiring level-shifting for full-rail input signals.
How does the power-down mode function on the OPA2836QDGKRQ1?
The OPA2836QDGKRQ1 does not include a dedicated power-down pin; instead, power-down is achieved by disconnecting the VS+ supply or forcing VS– to a voltage that violates absolute maximum ratings-which is not recommended. Per TI documentation, no integrated enable/disable control exists. System-level power gating must be implemented externally using load switches or PMIC-controlled rails to achieve 0.5 µA shutdown current.
Can the OPA2836QDGKRQ1 drive capacitive loads without oscillation?
Yes-the OPA2836QDGKRQ1 is unity-gain stable and characterized to drive ≥100 pF capacitive loads with appropriate series output resistance (e.g., 16.9 Ω for 100 pF per Figure 39). Without isolation resistance, instability may occur above ~20 pF. For camera module or cable-driven applications, always include a 10–49.9 Ω series resistor adjacent to the output pin and verify phase margin using TI's TINA-TI simulation model.
What is the typical input offset voltage drift over temperature for the OPA2836QDGKRQ1?
The OPA2836QDGKRQ1 exhibits an input offset voltage drift of ±1.1 µV/°C (max) over the full –40°C to +125°C automotive temperature range. At 25°C, typical offset is ±65 µV, increasing to ±1080 µV max at temperature extremes. This low drift enables stable DC-coupled gain stages in engine control temperature sensing without frequent calibration.
