Product details
Overview
TLV3801QDSGRQ1 from Texas Instruments is an AEC-Q100 qualified, 225-ps propagation delay, LVDS-output high-speed comparator in an 8-pin WSON (2.00 mm × 2.00 mm) package. It operates from a single supply (2.7 V to 5.25 V) or split supply, features ±0.5 mV input offset voltage, 2 mV internal hysteresis, and detects pulses as narrow as 240 ps - enabling precise timing capture in automotive LIDAR and time-of-flight sensors.
For engineers reviewing the TLV3801QDSGRQ1 datasheet, TLV3801QDSGRQ1 pinout, TLV3801QDSGRQ1 application, or TLV3801QDSGRQ1 equivalent, key selection criteria include sub-250-ps propagation delay consistency across temperature, LVDS-compatible differential output swing (250–450 mV), low overdrive dispersion (5 ps), and automotive-grade thermal performance (–40°C to +125°C).
Technical Context
The TLV3801QDSGRQ1 implements a fully differential, rail-to-rail input stage with separate VCC/VEE (input) and VCC/GND (LVDS output) supply domains, supporting both single-supply (VEE = GND) and true bipolar split-supply operation. Its architecture delivers 3 GHz toggle frequency and 6 Gbps data rate capability while maintaining <±2.5 ps propagation delay skew between rising/falling edges.
Internal 2 mV hysteresis suppresses noise-induced output chatter without compromising pulse fidelity; combined with 1 pF input capacitance and ±10 µA input bias current, it enables stable interfacing with high-impedance sources such as photodiode transimpedance amplifiers in optical receiver chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 225 ps typical - ensures sub-nanosecond timing resolution for LIDAR echo detection and ToF distance calculation. |
| Overdrive dispersion | 5 ps - guarantees consistent delay across input overdrive levels (20–100 mV), critical for accurate pulse-width measurement. |
| LVDS output swing | 250–450 mV differential - directly drives standard 100 Ω LVDS terminations on FPGAs and CPUs without level-shifting. |
| Input offset voltage | ±0.5 mV - minimizes threshold error in precision trigger applications like oscilloscope external trigger circuits. |
| Supply range | 2.7 V to 5.25 V (VCC–VEE) - supports flexible power architecture including 3.3 V single-supply and ±2.5 V split-supply configurations. |
| Operating temperature | –40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood automotive sensing systems. |
| Minimum pulse width | 240 ps - enables detection of ultra-short optical return pulses in high-resolution LIDAR systems. |
Pinout & Package
TLV3801QDSGRQ1 is housed in an 8-pin WSON package (2.00 mm × 2.00 mm) with wettable flanks, optimized for automated optical inspection (AOI) and high-reliability automotive PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+ | Non-inverting input | Accepts analog input signals referenced to VEE; common-mode range extends from VEE + 1.5 V to VCC + 0.1 V. |
| IN− | Inverting input | Differential pair input; internal ESD protection limits differential voltage to ≤1.4 V via back-to-back diodes. |
| OUT+ | Non-inverting LVDS output | Provides complementary LVDS signal; requires 100 Ω termination to GND at receiver end for proper common-mode (1.25 V). |
| OUT− | Inverting LVDS output | Delivers true differential LVDS output; suppresses common-mode noise and reduces EMI vs. single-ended signaling. |
| VEE | Negative supply | Input-stage negative rail; connect to GND for single-supply operation; supports split-supply down to –2.5 V. |
| VCC | Positive supply (pins 6 & 7) | Shared positive rail for input and LVDS output stages; must be ≥2.4 V above GND for LVDS functionality. |
| GND | Output ground reference | LVDS output stage reference; physically isolated from VEE to enable split-input/single-output supply configuration. |
| Thermal pad | Thermal & electrical connection | Must be soldered to PCB ground plane or connected to VEE for optimal thermal dissipation (RθJB = 36.2°C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply domain architecture | Independent VCC/VEE (input) and VCC/GND (output) rails enable bipolar input signals while maintaining LVDS-compliant output referencing. |
| Low-tempco propagation delay | ±0.2 ps/°C variation ensures timing stability across automotive temperature range without calibration. |
| Integrated 2 mV hysteresis | Prevents output oscillation on slow or noisy inputs without requiring external feedback components in most trigger applications. |
| High ESD robustness | ±2000 V HBM and ±1000 V CDM rating - meets AEC-Q100-002/-011 for reliable handling in automotive manufacturing environments. |
| Wettable flank WSON package | Enables automated optical inspection of solder joints - critical for zero-defect requirements in safety-critical ADAS modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH7322MA/NOPB | 450-ps propagation delay; CMOS output; no internal hysteresis; wider supply range (2.7–12 V). | Lower speed limits use in >1 GHz LIDAR; CMOS output requires external termination and lacks LVDS noise immunity. | Select when higher supply flexibility is needed and 225-ps timing is not required; verify layout for CMOS switching noise. |
| ADCMP572BCPZ-REEL7 | 150-ps propagation delay; PECL output; requires negative supply (–5.2 V); higher quiescent current (35 mA). | Superior speed but incompatible LVDS interface; PECL output demands level-shifting for FPGA interfacing and increases power. | Choose only if absolute minimum delay is critical and system already supports PECL infrastructure; not drop-in compatible. |
Compared with LMH7322MA/NOPB and ADCMP572BCPZ-REEL7, TLV3801QDSGRQ1 uniquely balances automotive qualification, LVDS-native output, sub-250-ps delay, and low-power operation - making it the optimal choice for space-constrained, safety-critical timing capture where interface simplicity and thermal reliability are prioritized over marginal speed gains.

FAQ
What is the maximum operating temperature range for TLV3801QDSGRQ1?
The TLV3801QDSGRQ1 is rated for continuous operation from –40°C to +125°C ambient temperature and is qualified per AEC-Q100 Grade 1. This range covers under-hood automotive environments and industrial test equipment enclosures without derating. Thermal resistance data (RθJA = 69.4°C/W) confirms safe junction temperatures under typical PCB copper pour conditions.
Does TLV3801QDSGRQ1 require external hysteresis for stable operation?
No - TLV3801QDSGRQ1 integrates 2 mV of internal hysteresis, sufficient for most high-speed trigger applications with clean input signals. External hysteresis is only needed when input noise exceeds this threshold or when precise, adjustable trip points are required; the datasheet provides resistor-based design guidance for non-inverting configurations.
Can TLV3801QDSGRQ1 operate from a single 3.3-V supply?
Yes - TLV3801QDSGRQ1 supports single-supply operation with VCC = 3.3 V and VEE tied to GND. The input common-mode range (VEE + 1.5 V to VCC + 0.1 V) becomes 1.5 V to 3.4 V, and the LVDS output functions correctly with VCC–GND ≥ 2.4 V, meeting all specifications at 3.3 V.
What LVDS termination is required for TLV3801QDSGRQ1 outputs?
TLV3801QDSGRQ1 outputs require a standard 100 Ω differential termination across OUT+ and OUT– at the receiver end. This establishes the correct 1.25 V common-mode voltage and 350 mV typical differential swing. No series resistors are needed at the driver side - the device drives directly into the 100 Ω load.
Is TLV3801QDSGRQ1 pin-compatible with TLV3802QDSGRQ1?
No - TLV3801QDSGRQ1 uses an 8-pin WSON package while TLV3802QDSGRQ1 uses a 12-pin WSON package with different pinout and dual-channel functionality. They share identical per-channel electrical specs but are not mechanically or electrically interchangeable; board redesign is required for substitution.
