Texas Instruments TLV9022DR

Overview

TLV9022DR from Texas Instruments is a dual-channel, open-drain output precision comparator with rail-to-rail fault-tolerant inputs, 300 µV input offset voltage, 100 ns propagation delay, and 16 µA per-channel quiescent current. It operates from 1.65 V to 5.5 V and supports industrial temperature range (–40°C to +125°C), enabling precise voltage monitoring in motor drives and factory automation systems.

For engineers reviewing the TLV9022DR datasheet, TLV9022DR pinout, TLV9022DR application, or TLV9022DR equivalent, key selection criteria include open-drain output compatibility with mixed-voltage logic translation, fault-tolerant input operation up to 6 V beyond supply rails, low-power operation for battery-backed monitoring, and SOIC-8 package suitability for legacy industrial PCB layouts.

Technical Context

The TLV9022DR implements a high-speed, low-power comparator architecture optimized for precision threshold detection under noisy conditions. Its input stage tolerates voltages up to 6 V regardless of supply, preventing phase inversion or damage during overvoltage transients - critical for industrial sensor interfaces.

Each channel features independent open-drain outputs capable of pull-up to any voltage ≤ 6 V, supporting level-shifting between 1.8 V, 3.3 V, and 5 V domains without external components. Propagation delay remains stable across temperature and supply voltage due to matched internal biasing.

FAQ

What is the maximum input voltage the TLV9022DR can tolerate without damage?

The TLV9022DR inputs tolerate voltages up to 6 V relative to V−, regardless of the supply voltage. This fault-tolerance eliminates external clamping components in applications exposed to inductive kickback or ESD transients, such as motor current sensing or industrial I/O modules. The specification is validated across the full −40°C to +125°C temperature range and applies to both IN1± and IN2± pins.

Does the TLV9022DR support operation from a 1.8 V supply?

Yes, the TLV9022DR operates from 1.65 V to 5.5 V, including 1.8 V nominal rails. At 1.8 V, it maintains 100 ns typical propagation delay and 16 µA per-channel quiescent current, with input common-mode range extending from (V−) − 0.2 V to (V+) + 0.2 V. This enables direct integration into low-voltage IoT edge nodes and battery-powered diagnostic tools without level-shifting circuitry.

Can the TLV9022DR outputs be pulled up to a voltage higher than V+?

Yes - the open-drain outputs of the TLV9022DR support pull-up voltages up to 6 V, independent of V+. This allows seamless level translation between disparate logic domains (e.g., 1.8 V MCU detecting 5 V sensor alerts). The output leakage current remains below 100 pA at 25°C, ensuring minimal power loss in high-impedance pull-up configurations used in battery-sensitive applications.

How does the TLV9022DR's input offset voltage affect accuracy in a 12-bit ADC reference monitor?

With a typical input offset voltage of ±0.3 mV, the TLV9022DR introduces less than 0.03% full-scale error when monitoring a 10 V reference - well within the resolution limit of a 12-bit (2.44 mV LSB) system. The drift of ±0.5 µV/°C further ensures stability across industrial temperature ranges, making it suitable for precision power supply validation in medical or test equipment where reference integrity is critical.

Is the TLV9022DR pin-compatible with other devices in the TLV902x/TLV903x family?

Yes - the TLV9022DR uses the industry-standard SOIC-8 footprint shared across all TLV902x (open-drain) and TLV903x (push-pull) dual comparators, including TLV9022IDR, TLV9032DR, and TLV9032IDR. Pin functions (IN1±, OUT1, IN2±, OUT2, V+, V−) are identical; only output stage topology differs. This enables design reuse and last-time-buy flexibility without PCB revision.
