Product details
Overview
TLV2316QDGKRQ1 from Texas Instruments is a dual-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, 6 V/µs slew rate, and ultra-low quiescent current of 400 µA per channel while maintaining ±0.75 mV max offset voltage and 12 nV/√Hz input voltage noise at 1 kHz - enabling precision signal conditioning in battery-powered ADAS sensor front-ends and current-sensing circuits.
For engineers reviewing the TLV2316QDGKRQ1 datasheet, TLV2316QDGKRQ1 pinout, TLV2316QDGKRQ1 application, or TLV2316QDGKRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (–40°C to +125°C), rail-to-rail I/O swing with <35 mV output saturation near rails, integrated RFI/EMI filtering, and stable operation driving 10 kΩ loads or 100 pF capacitive loads without external compensation.
Technical Context
The TLV2316QDGKRQ1 employs a complementary differential input stage (N- and P-channel pairs) enabling rail-to-rail common-mode input range extending 200 mV beyond supply rails - critical for single-supply systems interfacing with ADCs or high-impedance sensors. Its class AB output stage ensures full rail-to-rail output swing into 10 kΩ loads, with typical output voltage swing within 35 mV of either rail at 1.8 V supply.
Internally compensated for unity-gain stability, it achieves 60° phase margin and supports robust small-signal step response (1 µs to 0.1%) and fast overload recovery (0.8 µs), while its 1.3 fA/√Hz input current noise and ±10 pA input bias current preserve accuracy in megaohm-source applications like thermistor or photodiode amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual amplifier - enables compact dual-path signal conditioning (e.g., differential sensing + reference buffer) in one 8-pin VSSOP package. |
| Unity-Gain Bandwidth | 10 MHz - supports accurate amplification of signals up to ~1 MHz in closed-loop configurations with gain ≥2. |
| Quiescent Current | 400 µA per channel - enables always-on operation in automotive body electronics with minimal battery drain. |
| Input Offset Voltage | ±0.75 mV max - ensures ≤0.015% gain error in 50 mV full-scale current-sense applications at room temperature. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - preserves SNR in low-level sensor interfaces (e.g., strain gauges, RTDs) without requiring additional filtering. |
| Rail-to-Rail I/O | Input extends (V−) −0.2 V to (V+) +0.2 V; output swings to within 35 mV of rails - maximizes dynamic range in 1.8 V–3.3 V microcontroller systems. |
| AEC-Q100 Grade | Grade 1 (−40°C to +125°C ambient) - qualified for under-hood and cabin-mounted automotive ECUs without derating. |
Pinout & Package
TLV2316QDGKRQ1 is housed in an 8-pin VSSOP (DGK) package measuring 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 |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream circuitry (e.g., ADC input, comparator threshold); rail-to-rail swing supports full utilization of 12-bit+ converters. |
| 2 | –IN A | Inverting input, Channel A - connects to feedback network in inverting configurations; high impedance (10¹⁶ Ω || 2 pF) minimizes loading on precision dividers. |
| 3 | +IN A | Noninverting input, Channel A - accepts high-impedance sensor signals (e.g., thermocouple, pH electrode); ±10 pA bias current avoids voltage drop across >100 MΩ sources. |
| 4 | V− | Negative supply / ground reference - serves as common return for dual-supply (±0.9 V to ±2.75 V) or single-supply (0 V reference) operation. |
| 5 | +IN B | Noninverting input, Channel B - enables independent signal path (e.g., reference buffer or second sensor channel) without cross-talk (100 dB dc channel separation). |
| 6 | –IN B | Inverting input, Channel B - used for differential amplification or active filtering; identical electrical specs to Channel A ensure matched performance. |
| 7 | OUT B | Amplifier B output - provides simultaneous dual-output capability (e.g., buffered sensor + fault-detection comparator input). |
| 8 | V+ | Positive supply - accepts 1.8 V–5.5 V; internal regulation maintains stable IQ and bandwidth across entire range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with 200 mV beyond rails | Enables direct interface to 0–VREF sensor outputs (e.g., resistive touchscreens, battery cell monitors) without level-shifting circuitry. |
| Integrated RFI/EMI filter | Rejects >60 dB of 100 MHz–1 GHz interference at noninverting input - eliminates need for external ferrite beads or RC filters in noisy automotive environments. |
| No phase reversal in overdrive | Prevents latch-up or false triggering when inputs exceed common-mode range - critical for fault-detection comparators using op-amp outputs. |
| 4-kV HBM ESD rating | Withstands electrostatic discharge during handling and assembly without protection diodes - reduces BOM count and layout complexity. |
| Stable IQ over temperature/supply | Maintains 400 µA/ch quiescent current from –40°C to +125°C and 1.8 V–5.5 V - ensures predictable power budgeting in thermal-cycling automotive modules. |

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 |
|---|---|---|---|
| LMV358QDRQ1 | Lower bandwidth (1 MHz), higher IQ (150 µA/ch), no rail-to-rail input - limited to mid-supply common-mode ranges. | Suitable only for non-critical DC-coupled buffers where speed and input range are not constraints. | Choose when cost sensitivity outweighs bandwidth and rail-to-rail requirements; verify input common-mode compliance in 1.8 V systems. |
| TSV912IQDRQ1 | Higher bandwidth (8 MHz), lower noise (11 nV/√Hz), but no AEC-Q100 Grade 1 rating - rated only to +105°C ambient. | Not qualified for under-hood or transmission-control applications requiring full –40°C to +125°C operation. | Select only for cabin-only modules (e.g., infotainment sensors); confirm thermal derating meets system-level reliability targets. |
Compared with LMV358QDRQ1 and TSV912IQDRQ1, TLV2316QDGKRQ1 uniquely combines AEC-Q100 Grade 1 qualification, 10 MHz bandwidth, rail-to-rail I/O, and 400 µA/ch IQ - making it the only dual-channel option meeting full automotive under-hood signal-chain requirements without trade-offs in speed, power, or temperature range.

FAQ
What automotive qualification level does TLV2316QDGKRQ1 meet?
TLV2316QDGKRQ1 is AEC-Q100 qualified to Grade 1, with device-level testing confirming reliable operation across –40°C to +125°C ambient temperature, 4-kV HBM ESD tolerance, and CDM Level C5 (±750 V) - fully compliant for engine bay, transmission, and chassis-mounted ECUs.
Can TLV2316QDGKRQ1 operate from a single 1.8 V supply?
Yes, TLV2316QDGKRQ1 is fully specified and functional from 1.8 V to 5.5 V single-supply operation. Its rail-to-rail input extends to (V−) −0.2 V and (V+) +0.2 V, and output swings to within 35 mV of both rails - enabling full dynamic range utilization in 1.8 V microcontroller-based systems.
Does TLV2316QDGKRQ1 require external compensation for unity-gain stability?
No, TLV2316QDGKRQ1 is internally compensated and unity-gain stable. It maintains ≥60° phase margin driving 100 pF capacitive loads at G = 1, with 1 µs settling time to 0.1% - eliminating need for external compensation components in most buffer and gain-of-one configurations.
How does the internal RFI/EMI filter in TLV2316QDGKRQ1 improve system robustness?
The integrated low-pass filter on TLV2316QDGKRQ1's inputs attenuates high-frequency electromagnetic interference (e.g., AM/FM band, switching regulator noise) before rectification occurs - reducing output DC offset shifts by >60 dB at 100 MHz–1 GHz and eliminating need for discrete EMI suppression components in automotive harnesses.
What is the maximum capacitive load TLV2316QDGKRQ1 can drive without instability?
TLV2316QDGKRQ1 remains stable driving up to 100 pF capacitive load in unity-gain configuration, as verified by 40° phase margin and <25% overshoot. For larger loads (>100 pF), adding a 10–20 Ω series resistor at the output (per Figure 14 in SBOS845B) restores stability while introducing minimal gain error.
