TL3116ID

Comparators Overview

The TL3116ID is an ultra-fast, low-power precision comparator manufactured by Texas Instruments. Designed for high-speed applications, it operates from a single 5-V supply or dual ±5-V supplies with a typical positive supply current of 12.7 mA. It features complementary outputs capable of latching via the LATCH ENABLE terminal and extends its input common-mode voltage range to include the negative rail for ground sensing. The device offers tight offset voltage specifications and functions as a pin-for-pin replacement for the LT1116.

Comparators Procurement Notes

Verify the specific package configuration required for your design, as the TL3116ID is available in SOIC (D) and TSSOP (PW) formats. Confirm that the operating temperature range of -40°C to 85°C aligns with your environmental requirements. Ensure proper handling procedures are followed during assembly to maintain device reliability.

Comparators Selection Notes

Select the TL3116ID when high-speed response times near 10 ns are critical alongside low power constraints. Its ability to operate from a single 5-V supply simplifies power distribution compared to devices requiring higher voltages. The inclusion of a latch function provides additional control over output states in complex digital interfaces.

Comparators Part Context

The TL3116 series represents Texas Instruments' solution for bridging analog signal detection with digital logic levels efficiently. By offering a functional replacement for the LT1116, it maintains compatibility with existing designs while providing improved power efficiency. This places it within the category of specialized high-speed comparators intended for industrial and consumer electronics.

Comparators Replacement Considerations

The datasheet explicitly identifies the TL3116 as a pin-for-pin functional replacement for the LT1116 comparator. Designers transitioning from the LT1116 can utilize the TL3116ID directly without modifying the PCB footprint or circuit topology.

Comparators FAQ

Can the TL3116ID operate with a single power supply?

Yes, the device is designed to operate from a single 5-V supply or from split ±5-V supplies.

What is the purpose of the LATCH ENABLE terminal?

The LATCH ENABLE terminal allows the user to latch the complementary outputs, holding the output state regardless of subsequent input changes until the latch is reset.

Does the input common-mode voltage range extend below ground?

Yes, the input common-mode voltage includes the negative rail, enabling ground sensing applications even when using a single positive supply.
