Product details
Overview
TLV6002QDGKRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 qualified rail-to-rail input/output operational amplifier designed for automotive signal conditioning in body electronics and infotainment systems. It operates from 1.8 V to 5.5 V, delivers 1 MHz gain-bandwidth, draws only 75 µA per channel, and features 0.75 mV typical offset voltage and 28 nV/√Hz input voltage noise at 1 kHz.
For engineers reviewing the TLV6002QDGKRQ1 datasheet, TLV6002QDGKRQ1 pinout, TLV6002QDGKRQ1 application, or TLV6002QDGKRQ1 equivalent, key selection criteria include its automotive-grade temperature range (–40°C to +125°C), low quiescent current for battery-sensitive designs, rail-to-rail operation enabling single-supply ADC interfacing, and integrated RF/EMI filtering for noisy vehicle environments.
Technical Context
The TLV6002QDGKRQ1 employs a complementary differential input stage-N-channel and P-channel pairs-to achieve rail-to-rail input operation with ±200 mV beyond supply rails, though CMRR and PSRR degrade within the transition region near (V+) – 1.3 V. Its class AB output stage enables full rail-to-rail swing, delivering ≤5 mV from rails into 100 kΩ loads.
It is unity-gain stable and supports capacitive loads up to 1 nF without external compensation; internal EMI rejection filtering targets ~35 MHz cutoff with 20 dB/decade rolloff, and input bias current remains ultra-low at ±1 pA (typ) across temperature, enabling high-impedance sensor interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct connection to automotive 3.3 V or 5 V rails and low-power 1.8 V microcontrollers. |
| Gain Bandwidth Product | 1 MHz - enables stable amplification of signals up to ~100 kHz at moderate closed-loop gains for sensor buffering and ADC driving. |
| Quiescent Current | 75 µA per channel - allows integration into always-on automotive modules without excessive battery drain. |
| Input Offset Voltage | 0.75 mV (typ) - ensures <0.1% error in 12-bit ADC front-ends with ±2.5 V full-scale range. |
| Input Voltage Noise | 28 nV/√Hz at 1 kHz - suitable for precision analog sensing where thermal noise dominates over 1/f noise. |
| CMRR / PSRR | 76 dB / 86 dB (min) - maintains accuracy in automotive environments with varying common-mode transients and supply ripple. |
| Operating Temperature | –40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood and cabin-mounted ECUs. |
Pinout & Package
TLV6002QDGKRQ1 is packaged in an 8-pin VSSOP (DGK) with nominal body size 3.00 mm × 3.00 mm, optimized for space-constrained automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream circuitry; rail-to-rail swing enables full dynamic range utilization. |
| 2 | –IN A | Inverting input, channel A - used in inverting configurations or feedback networks; accepts signals down to V– – 0.2 V. |
| 3 | +IN A | Noninverting input, channel A - accepts rail-to-rail common-mode inputs; critical for high-impedance sensor interfaces. |
| 4 | V– | Negative supply terminal - connects to ground or lowest system potential; reference for both channels. |
| 5 | +IN B | Noninverting input, channel B - independent input for second signal path; enables dual-sensor monitoring on one IC. |
| 6 | –IN B | Inverting input, channel B - supports separate feedback loop for channel B; identical electrical behavior to pin 2. |
| 7 | OUT B | Amplifier B output - electrically isolated from OUT A; allows simultaneous processing of two analog signals. |
| 8 | V+ | Positive supply terminal - powers both amplifiers; accepts up to 5.5 V with no derating required. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from –40°C to +125°C ambient, including HBM ESD Level 3A (±4 kV) and CDM Level C6 (±1 kV). |
| Rail-to-rail input and output | Enables single-supply operation with full signal swing; input extends 200 mV beyond rails, output swings within 5 mV of rails into 100 kΩ. |
| Ultra-low input bias current | ±1 pA (typ) at 25°C - preserves signal integrity when interfacing with megaohm-source sensors like thermistors or piezoelectric elements. |
| Integrated RF/EMI filter | 35 MHz cutoff low-pass filter on inputs suppresses high-frequency noise from ignition systems, motors, and wireless transceivers. |
| Unity-gain stability with capacitive loads | Stable driving up to 1 nF pure capacitance - eliminates need for external isolation resistors in many ADC buffer applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel automotive op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM7332QMA/NOPB | Higher quiescent current (1.1 mA/ch), wider GBW (20 MHz), no integrated EMI filter, SOIC-8 only. | Better for high-speed active filters or fast transient response; less suitable for always-on low-power modules. | Choose LM7332QMA/NOPB when bandwidth >5 MHz is required and power budget permits >1 mA/ch. |
| TSV912IQ2T | Lower offset (1.5 mV max), lower noise (18 nV/√Hz), but not AEC-Q100 qualified; 3.3 V min supply, VSSOP-8 package. | Acceptable for non-safety-critical cabin modules with tighter noise budgets but no formal automotive qualification. | Choose TSV912IQ2T only for cost-sensitive non-AEC-Q100 applications where qualification is not mandated. |
Compared with LM7332QMA/NOPB and TSV912IQ2T, TLV6002QDGKRQ1 uniquely balances AEC-Q100 compliance, ultra-low power (75 µA/ch), and integrated EMI filtering-making it the preferred choice for battery-conscious, safety-relevant automotive signal chains where 1 MHz bandwidth suffices.

FAQ
What is the maximum capacitive load TLV6002QDGKRQ1 can drive while remaining unity-gain stable?
The TLV6002QDGKRQ1 remains unity-gain stable with pure capacitive loads up to approximately 1 nF, as confirmed in the datasheet's capacitive load and stability section. For loads exceeding this value-such as bulk decoupling or long traces-an external series resistor (10 Ω to 20 Ω) between the output and load is recommended to maintain phase margin. This technique mitigates overshoot and ringing but introduces a small gain error due to voltage division; the TLV6002QDGKRQ1's low output impedance minimizes impact in most implementations.
Does TLV6002QDGKRQ1 support true rail-to-rail input operation across its full temperature range?
Yes, TLV6002QDGKRQ1 supports rail-to-rail input operation from –40°C to +125°C, with the common-mode input voltage range specified as (V–) – 0.2 V to (V+) + 0.2 V. However, performance parameters-including CMRR, PSRR, offset voltage, and offset drift-degrade within the transition region near (V+) – 1.3 V, as documented in the feature description. For highest accuracy, design inputs to operate outside this region; the TLV6002QDGKRQ1's guaranteed specification over temperature confirms functional rail-to-rail capability despite localized parameter variation.
Is TLV6002QDGKRQ1 pin-compatible with other dual op amps in VSSOP-8 packages?
No, TLV6002QDGKRQ1 is not pin-compatible with generic dual op amps in VSSOP-8 packages such as the LMV358 or MCP6022. Its pinout-OUT A, –IN A, +IN A, V–, +IN B, –IN B, OUT B, V+-is specific to the TLV600x-Q1 family and differs from industry-standard dual op amp arrangements. Substitution requires PCB layout revision. Always verify pin mapping against the official TLV6002QDGKRQ1 datasheet before board design or replacement.
What is the significance of the "Q1" suffix in TLV6002QDGKRQ1?
The "Q1" suffix in TLV6002QDGKRQ1 denotes AEC-Q100 qualification for automotive applications, specifically Grade 1 (–40°C to +125°C operating temperature). It signifies that the device has undergone stress testing for reliability, including HTOL, TC, UHAST, and ESD per AEC-Q100 standards, and is manufactured in TI's certified automotive production flow. This distinguishes TLV6002QDGKRQ1 from commercial-grade variants like TLV6002IDGKR, which lack automotive qualification and extended temperature validation.
Can TLV6002QDGKRQ1 be used in single-supply sensor interface circuits with ground-referenced inputs?
Yes, TLV6002QDGKRQ1 is explicitly designed for single-supply operation with ground-referenced inputs. Its rail-to-rail input stage accepts common-mode voltages from V– (ground) to V+ + 0.2 V, and its rail-to-rail output swings within 5 mV of ground when loaded with ≥100 kΩ. When used with a 3.3 V or 5 V supply, it directly interfaces with ground-referenced thermistors, potentiometers, or bridge sensors without level-shifting circuitry-reducing BOM count and improving accuracy in TLV6002QDGKRQ1-based sensor nodes.
