Texas Instruments TLV3011AIDCKTG4

Overview

TLV3011AIDCKTG4 from Texas Instruments is a low-power, open-drain output comparator with integrated 1.242 V voltage reference, 3.1 μA maximum quiescent current (B-version), input common-mode range extending 200 mV beyond rails, and operation from 1.65 V to 5.5 V. It serves as a precision threshold detector in battery-constrained systems such as toll tags and asset tracking devices.

For engineers reviewing the TLV3011AIDCKTG4 datasheet, TLV3011AIDCKTG4 pinout, TLV3011AIDCKTG4 application, or TLV3011AIDCKTG4 equivalent, key selection criteria include its guaranteed 2–4 μs propagation delay (low-to-high/high-to-low), ±0.25% reference accuracy, fail-safe inputs, power-on-reset functionality, and SC-70-6 package compatibility for space-constrained PCB layouts.

Technical Context

The TLV3011AIDCKTG4 implements a rail-to-rail input comparator core paired with a buffered, low-drift series voltage reference (100 ppm/°C max). Its internal hysteresis (2–8 mV) and fail-safe input architecture ensure robust switching under noisy or floating-input conditions.

Designed for single-supply operation, it supports true 1.65 V minimum supply voltage and delivers stable reference output capable of sourcing/sinking up to 0.5 mA while maintaining ≤1 mV/mA load regulation - enabling direct sensor biasing or ADC reference sharing without external buffering.

Key Specifications

Pinout & Package

FAQ

What is the reference voltage accuracy of TLV3011AIDCKTG4 over temperature?

The TLV3011AIDCKTG4 reference voltage has ±0.25% initial accuracy at 25°C and maintains ≤100 ppm/°C drift over –40°C to +125°C. This translates to ±0.0124 V total variation across full temperature range - sufficient for 12-bit ADC thresholding without calibration.

Does TLV3011AIDCKTG4 require an external pull-up resistor on the OUT pin?

Yes, TLV3011AIDCKTG4 features an open-drain output and requires an external pull-up resistor to define the high-state voltage level. Typical values range from 10 kΩ to 100 kΩ depending on speed and drive strength requirements; the device itself does not integrate pull-up circuitry.

Can TLV3011AIDCKTG4 operate from a 1.65 V supply?

Yes, TLV3011AIDCKTG4 is rated for 1.65 V to 5.5 V supply operation per its "B" version specification. At 1.65 V, it maintains functional comparator behavior, 2–4 μs propagation delay, and stable 1.242 V reference output - validated across –40°C to +125°C.

How does the fail-safe input feature work in TLV3011AIDCKTG4?

The fail-safe input architecture in TLV3011AIDCKTG4 ensures that if either IN+ or IN– is left floating or disconnected, the comparator output defaults to a known logic state (high for open-drain OUT with pull-up). This prevents undefined behavior during power-up, sensor disconnection, or wiring faults.

Is TLV3011AIDCKTG4 pin-compatible with non-B versions like TLV3011IDCKR?

No, TLV3011AIDCKTG4 is not pin-compatible with non-B versions. While both use SC-70-6 packaging, the "B" version integrates power-on-reset, fail-safe inputs, and hysteresis - requiring different internal biasing and control logic. Substitution would necessitate validation of timing, startup behavior, and noise immunity in the target application.
