TLV9022DR

Comparators Overview

The TLV9022DR is a dual-channel precision analog comparator from Texas Instruments, featuring an open-drain output configuration. It operates within a supply voltage range of 1.65V to 5.5V and delivers a typical propagation delay of 100ns with a quiescent current of 16μA per channel. The device ensures high accuracy with a maximum input offset voltage of ±1.5mV and low input bias current of 5pA. Inputs are fault-tolerant up to 6V without damage or phase inversion. It supports rail-to-rail input signals and includes 2kV ESD protection, functioning reliably across the industrial temperature range of -40°C to +125°C.

Comparators Feature Summary

• Fault-tolerant inputs capable of withstanding voltages up to 6V without damage or output phase inversion
• Open-drain output stage allowing pull-up voltages below or beyond the positive supply rail
• Rail-to-rail input capability for full signal utilization across the supply range
• High precision performance characterized by low input offset voltage and minimal input bias current

Comparators Applications

• Appliances
• Building automation
• Factory automation and control
• Motor drives
• Infotainment and cluster systems

Comparators Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest orderable addendum to ensure authenticity. Confirm that the open-drain output requirement aligns with the system design, as this variant lacks the push-pull drive capability found in the TLV903x series. Ensure proper pull-up resistor selection for the desired logic levels.

Comparators Selection Notes

Select the TLV9022DR when an open-drain output is required for level shifting or wired-OR configurations. This part is suitable for applications demanding precise voltage monitoring in noisy environments due to its fault-tolerant inputs. Consider the TLV9032DR if a push-pull output stage is needed to drive capacitive loads or LEDs directly.

Comparators Part Context

The TLV9022DR belongs to the TLV902x/TLV903x Precision Comparator Family. It shares core electrical characteristics with single (TLV9020/21) and quad (TLV9024) variants, differing primarily in channel count and pinout. The 'DR' suffix indicates the SOIC-8 surface-mount package. It is designed for industrial applications requiring robust performance under varying supply conditions.

Comparators Replacement Considerations

The TLV9032DR serves as a functional substitute within the same family but features a push-pull output instead of open-drain. Verify compatibility regarding output drive requirements and pull-up circuitry before substitution.
