Product details
Overview
TLV4316QPWRQ1 from Texas Instruments is a quad-channel, rail-to-rail input/output automotive-grade 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 400 µA per channel quiescent current, enabling high-speed signal conditioning in battery-powered ADAS sensors and body control modules.
For engineers reviewing the TLV4316QPWRQ1 datasheet, TLV4316QPWRQ1 pinout, TLV4316QPWRQ1 application, or TLV4316QPWRQ1 equivalent, this page provides verified specifications, TSSOP-14 pin mapping, automotive-grade ESD performance (±4 kV HBM), and validated alternatives for precision analog front-ends in AEC-Q100 Grade 1 systems.
Technical Context
The TLV4316QPWRQ1 employs a complementary differential input stage-N-channel and P-channel pairs-to achieve rail-to-rail common-mode input range extending 200 mV beyond supply rails at VS > 2.5 V. Its class AB output stage drives 10-kΩ loads to within 35 mV of either rail across full supply and temperature range.
It features integrated RFI/EMI filtering on input pins, no phase reversal under overdrive, and stable 60° phase margin at unity gain. Electrical behavior-including PSRR degradation and offset voltage shift-is characterized across the transition region (VCM ≈ V+ − 1.4 V to V+ − 1.0 V), where both input pairs are active.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 4 independent amplifiers in single package-enables compact multi-sensor signal conditioning without inter-chip routing. |
| Unity-Gain Bandwidth | 10 MHz-supports accurate amplification of fast transients in current sensing and ADC driver applications. |
| Quiescent Current | 400 µA per channel-enables always-on monitoring circuits with sub-2 mA total supply draw at 5 V. |
| Input Offset Voltage | ±0.75 mV (typical)-ensures <1 LSB error when driving 12-bit SAR ADCs with 3.3 V reference. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz-preserves SNR in high-impedance sensor interfaces like thermopiles or strain gauges. |
| Supply Range | 1.8 V to 5.5 V-operates directly from Li-ion battery (3.0–4.2 V) or 3.3 V/5 V system rails without LDO. |
| ESD Rating | HBM ±4 kV, CDM ±750 V-meets AEC-Q100 stress requirements for under-hood and infotainment environments. |
Pinout & Package
TSSOP-14 (PW) package, 4.40 mm × 5.00 mm body size, 0.65 mm pitch, surface-mount, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A/B/C/D | Amplifier outputs-rail-to-rail swing enables direct interface to SAR ADC inputs or comparator thresholds. |
| 2, 6, 9, 13 | –IN A/B/C/D | Inverting inputs-support transimpedance, difference, and active filter configurations with matched layout. |
| 3, 5, 10, 12 | +IN A/B/C/D | Noninverting inputs-accept signals from resistive sensors, voltage dividers, or buffered references. |
| 4 | V+ | Positive supply rail-must be decoupled locally with 100 nF ceramic capacitor to suppress supply noise coupling. |
| 11 | V– | Negative supply or ground-serves as common return for all four channels; requires low-impedance PCB plane. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode range extends 200 mV beyond rails; output swings to within 35 mV of V+ or V–-maximizes dynamic range in 1.8 V systems. |
| EMI Filtering | Integrated low-pass filter on input pins reduces rectified offset shift from GSM/Bluetooth interference-critical for cabin microphones and radar receivers. |
| No Phase Reversal | Output remains monotonic during input overdrive-prevents latch-up or false triggering in comparator-based fault detection circuits. |
| Low Input Bias Current | ±10 pA-enables use with >1 MΩ source impedances (e.g., pH electrodes, pyroelectric sensors) without significant DC error. |
| Stable IQ vs Temp | Quiescent current varies only ±10% from –40°C to +125°C-eliminates thermal drift in battery-life calculations for telematics modules. |
Applications
| ADAS Camera Signal Chain | Automotive Battery Monitoring |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV4316IPWR | Industrial-grade (–40°C to +125°C), same electrical specs but no AEC-Q100 qualification or automotive ESD ratings. | Lacks HBM ±4 kV and CDM ±750 V-unsuitable for safety-critical vehicle domains without additional board-level protection. | Select TLV4316IPWR only for non-automotive industrial control or test equipment where automotive qualification is unnecessary. |
| LMV324QDRQ1 | Lower bandwidth (1 MHz), higher IQ (130 µA/ch), no EMI filtering, and no rail-to-rail input-requires external level-shifting for 1.8 V operation. | Cannot drive 12-bit ADCs at full speed or interface directly to low-voltage sensors without signal loss. | Choose LMV324QDRQ1 only when cost is primary constraint and bandwidth/noise requirements are relaxed below 1 MHz. |
Compared with TLV4316QPWRQ1, TLV4316IPWR offers identical analog performance but lacks automotive reliability validation, while LMV324QDRQ1 trades bandwidth, noise, and input flexibility for lower unit cost-making TLV4316QPWRQ1 the only option meeting AEC-Q100 Grade 1 timing, noise, and rail-to-rail requirements simultaneously.

FAQ
What is the operating temperature range for TLV4316QPWRQ1?
The TLV4316QPWRQ1 is qualified for AEC-Q100 Grade 1 operation from –40°C to +125°C ambient temperature. This range is fully supported by electrical specifications including offset voltage, CMRR, and quiescent current-verified across the entire span without derating. The device's thermal metrics (RθJA = 117.8°C/W) ensure reliable junction temperatures under typical automotive PCB layouts.
Does TLV4316QPWRQ1 support rail-to-rail input at 1.8 V supply?
Yes, TLV4316QPWRQ1 supports rail-to-rail input at 1.8 V supply. Its complementary input stage maintains common-mode range from (V–) – 0.2 V to (V+) + 0.2 V across the full 1.8 V to 5.5 V supply range. At 1.8 V, this translates to –0.2 V to +2.0 V-enabling direct interface with sensors referenced to ground or split supplies without level-shifting circuitry.
Can TLV4316QPWRQ1 drive a 100-pF capacitive load stably?
Yes, TLV4316QPWRQ1 is characterized for stable operation with 100-pF capacitive loads in unity-gain configuration. Typical overshoot is <25% with 40° phase margin, as shown in Figure 7 of the datasheet. For higher stability margins, adding a 10-Ω series resistor at the output reduces ringing without compromising DC accuracy in most sensor buffering applications.
What is the maximum output current capability of TLV4316QPWRQ1?
TLV4316QPWRQ1 delivers ±50 mA short-circuit output current per channel at 5 V supply, as specified in Absolute Maximum Ratings. Under normal linear operation into 10-kΩ loads, it sources/sinks up to ±3 mA while maintaining rail-to-rail swing and 0.1% settling. Output current capability decreases slightly at lower supply voltages but remains sufficient for driving ADC inputs, comparators, and small MOSFET gates.
Is TLV4316QPWRQ1 pin-compatible with other devices in the TLVx316-Q1 family?
No, TLV4316QPWRQ1 is not pin-compatible with TLV316-Q1 (SOT-23-5) or TLV2316-Q1 (VSSOP-8). It uses the TSSOP-14 (PW) package with dedicated pins for four independent amplifiers (14 pins total), whereas the single and dual variants use smaller footprints with shared supply pins. PCB layout must be designed specifically for the 14-pin TSSOP footprint of TLV4316QPWRQ1.
