Texas Instruments TLV3801DSGR

Overview

TLV3801DSGR from Texas Instruments is a single-channel, 225-ps propagation delay high-speed comparator with LVDS differential outputs, designed for precision timing-critical detection in optical sensing and test equipment. It operates from 2.7 V to 5.25 V single supply (VEE = GND), delivers 240-ps minimum input pulse width detection, features ±0.5 mV input offset voltage, and integrates 2 mV internal hysteresis - enabling reliable edge discrimination in LIDAR receiver front-ends.

For engineers reviewing the TLV3801DSGR datasheet, TLV3801DSGR pinout, TLV3801DSGR application, or TLV3801DSGR equivalent, this page provides verified electrical parameters, package-specific pin functions, real-world use cases in time-of-flight systems, and validated alternative comparators for high-speed differential signal conditioning where sub-nanosecond timing fidelity and LVDS compatibility with FPGAs are required.

Technical Context

The TLV3801DSGR employs a fully differential input stage referenced to split supplies (VCC/VEE) and an LVDS output driver referenced to VCC/GND, allowing independent optimization of input common-mode range and output signal integrity. Its architecture supports both single-supply (VEE = GND) and true split-supply operation while maintaining 5 ps overdrive dispersion and ±2.5 ps propagation delay skew across temperature.

Internal hysteresis (2 mV) stabilizes switching against noise without degrading small-signal response, and the 3 GHz toggle frequency (6 Gbps) is achieved via optimized current-steering output stages driving 100-Ω differential terminations - directly compatible with standard LVDS receivers in FPGA-based data acquisition systems.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating temperature for TLV3801DSGR?

The TLV3801DSGR is rated for operation from –40°C to +125°C ambient temperature. Its thermal resistance (RθJA = 69.4°C/W) and thermal pad design enable sustained performance at full specification within this range when mounted on a 2-layer PCB with adequate copper pour and thermal vias - critical for under-hood LIDAR modules and industrial test equipment.

Does TLV3801DSGR require external hysteresis for stable operation?

No - TLV3801DSGR includes 2 mV of internal hysteresis, which is sufficient to prevent chatter in most high-noise optical receiver applications. External hysteresis is only needed when input signals exhibit slow slew rates (<1 V/ns) or when system-level noise exceeds the internal hysteresis margin; the datasheet provides resistor network guidance for such cases.

Can TLV3801DSGR operate from a 3.3 V single supply?

Yes - TLV3801DSGR supports 3.3 V single-supply operation (VCC = 3.3 V, VEE = GND). At this rail, it maintains 225-ps propagation delay, 240-ps minimum pulse width detection, and full LVDS output compliance (1.25 V common-mode, ±350 mV swing), making it ideal for FPGA-based 3.3 V systems in portable ToF sensors.

How does TLV3801DSGR differ from TLV3811C in terms of supply configuration?

TLV3801DSGR supports split-supply operation (VCC and VEE) for extended input common-mode range, while TLV3811C uses a single supply (VCC and GND only) and lacks separate VEE. TLV3801DSGR also includes 2 mV internal hysteresis versus 0 mV in TLV3811C - making TLV3801DSGR better suited for noisy environments where input signal integrity varies.

Is TLV3801DSGR pin-compatible with other comparators in the TLV38xx family?

No - TLV3801DSGR uses an 8-pin WSON package with specific pin assignments (e.g., dual VCC pins, dedicated VEE), whereas TLV3811(C) uses a 6-pin DSBGA and TLV3802 uses a 12-pin WSON. Pinouts are not interchangeable; PCB layout must match the exact package footprint and thermal pad connection requirements of TLV3801DSGR.
