Product details
Overview
TLV2316QDGKTQ1 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 400 µA per-channel quiescent current while maintaining ±0.75 mV offset voltage and 12 nV/√Hz input voltage noise at 1 kHz - enabling precision signal conditioning in battery-powered ADAS sensor interfaces and current-sensing circuits.
For engineers reviewing the TLV2316QDGKTQ1 datasheet, TLV2316QDGKTQ1 pinout, TLV2316QDGKTQ1 application, or TLV2316QDGKTQ1 equivalent, this page provides verified technical context, automotive-qualified specifications, validated pin functions for the DGK (VSSOP-8) package, real-world use cases in body electronics and BMS, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The TLV2316QDGKTQ1 implements a complementary-input-stage architecture enabling rail-to-rail common-mode input range (extending 200 mV beyond rails at VS > 2.5 V) and a class AB output stage delivering full rail-to-rail swing within 35 mV of supply rails under 10 kΩ load. Its 10-MHz gain-bandwidth product and 60° phase margin ensure unity-gain stability even with capacitive loads up to 100 pF.
Designed for AEC-Q100 Grade 1 (–40°C to +125°C), it integrates internal RFI/EMI filtering, exhibits no phase reversal during overdrive, and maintains stable IQ across temperature and supply voltage - critical for reliable operation in automotive body control modules and battery monitoring systems where supply ripple and EMI are prevalent.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.8 V to 5.5 V - supports direct connection to Li-ion battery stacks and 3.3-V/5-V automotive domains without LDO overhead. |
| Unity-Gain Bandwidth | 10 MHz - enables accurate amplification of fast transients in motor current sensing and radar front-end buffering. |
| Quiescent Current | 400 µA per channel - allows dual-opamp deployment in always-on vehicle subsystems without compromising battery life. |
| Input Offset Voltage | ±0.75 mV (typ) - ensures ≤0.015% error in 50-mV shunt-based current measurement at room temperature. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - preserves SNR in high-impedance sensor interfaces like piezoresistive pressure transducers. |
| CMRR | 72–90 dB - rejects common-mode interference from noisy 12-V power nets in body electronics applications. |
| ESD Rating | HBM ±4 kV, CDM ±750 V - meets AEC-Q100 stress requirements for assembly and field reliability in automotive harness environments. |
Pinout & Package
VSSOP-8 (DGK) package: 3.00 mm × 3.00 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected), RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT A | Output, Channel A | Capable of rail-to-rail swing within 35 mV of V+ or V− under 10 kΩ load; drives ADC inputs directly. |
| 2: –IN A | Inverting Input, Channel A | High-impedance node (10¹⁶ Ω || 2 pF); accepts signals from high-Z sources like thermistors or photodiodes. |
| 3: +IN A | Noninverting Input, Channel A | Complementary input pair enables rail-to-rail common-mode range; used for reference-biased sensor buffers. |
| 4: V− | Negative Supply / Ground | Reference for single-supply operation; must be decoupled locally to suppress ground bounce in mixed-signal PCBs. |
| 5: +IN B | Noninverting Input, Channel B | Independent input path for dual-function circuits such as differential-to-single-ended conversion with matched gain. |
| 6: –IN B | Inverting Input, Channel B | Matches Channel A characteristics; enables precise current-sense amplification with external gain-setting resistors. |
| 7: OUT B | Output, Channel B | Electrically isolated from OUT A; supports independent feedback paths without crosstalk (≥100 dB at DC). |
| 8: V+ | Positive Supply | Accepts 1.8–5.5 V; internal regulation ensures stable biasing across automotive battery voltage transients (e.g., cold-crank). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input extends 200 mV beyond rails; output swings to within 35 mV of V+ or V− - maximizes dynamic range in 3.3-V ADC driver stages. |
| EMI/RFI Filtering | Integrated input low-pass filter reduces rectified offset shift from GSM/Bluetooth interference - critical for infotainment sensor nodes. |
| No Phase Reversal | Remains stable during input overdrive - prevents latch-up or erroneous triggering in window-comparator circuits for battery cell monitoring. |

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 |
|---|---|---|---|
| TLV2372QDRQ1 | Lower bandwidth (3 MHz), higher IQ (1000 µA/ch), same rail-to-rail I/O and AEC-Q100 Grade 1 rating. | Less suitable for high-speed current sensing but adequate for slow-responding HVAC actuators or potentiometer interfaces. | Choose when power budget permits higher IQ and bandwidth demands are ≤3 MHz - e.g., cabin temperature control loops. |
| LM7332QMA/NOPB | Higher bandwidth (20 MHz), higher IQ (1.3 mA/ch), wider supply (2.7–36 V), no integrated EMI filter. | Supports 24-V commercial vehicle systems but lacks built-in RFI rejection - requires external filtering for infotainment proximity sensors. | Choose for 24-V chassis applications needing >10-MHz bandwidth and robust output drive (>60 mA), accepting added layout complexity. |
Compared with TLV2316QDGKTQ1, TLV2372QDRQ1 trades bandwidth for lower cost and simpler thermal design, while LM7332QMA/NOPB extends voltage range and speed at the expense of EMI resilience and quiescent power - making TLV2316QDGKTQ1 optimal for 12-V/3.3-V ADAS and body electronics where noise immunity and ultra-low IQ are mandatory.

FAQ
What is the operating temperature range for TLV2316QDGKTQ1?
The TLV2316QDGKTQ1 is qualified per AEC-Q100 Grade 1 with an ambient operating temperature range of –40°C to +125°C. All electrical specifications in the datasheet are guaranteed across this full range, including offset voltage drift (±2 µV/°C), quiescent current stability, and CMRR performance - making it suitable for under-hood and cabin-mounted automotive ECUs without thermal derating.
Does TLV2316QDGKTQ1 support single-supply operation?
Yes, TLV2316QDGKTQ1 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, and its rail-to-rail output swings to within 35 mV of either rail under 10 kΩ load - enabling direct interfacing with 3.3-V microcontrollers and SAR ADCs without level-shifting circuitry.
Is TLV2316QDGKTQ1 pin-compatible with other devices in the TLVx316-Q1 family?
No - TLV2316QDGKTQ1 uses the 8-pin VSSOP (DGK) package, while TLV316-Q1 uses 5-pin SOT-23 and TLV4316-Q1 uses 14-pin TSSOP. Pin functions are consistent across channels (e.g., OUT A, –IN A), but physical pin count, spacing, and thermal pad configuration differ. PCB layout must be specific to the DGK footprint for TLV2316QDGKTQ1.
What is the maximum capacitive load TLV2316QDGKTQ1 can drive stably?
TLV2316QDGKTQ1 remains unity-gain stable with capacitive loads up to 100 pF, as verified by small-signal step response testing. For larger loads (e.g., >100 pF), a 10–20 Ω series resistor at the output is recommended to suppress overshoot - though this introduces gain error in precision applications. Layout best practices (short traces, local decoupling) further enhance stability.
How does the internal EMI filter in TLV2316QDGKTQ1 improve system reliability?
The integrated RFI/EMI filter in TLV2316QDGKTQ1 attenuates high-frequency interference (e.g., from Bluetooth, cellular, or switching regulators) before it reaches the input stage - preventing rectification-induced offset shifts that would corrupt sensor readings. This eliminates the need for external RC filters in space-constrained automotive modules like mirror control units or seat occupancy sensors.
