TLV1922DSGR

Comparators Overview

The TLV1922DSGR is a dual-channel analog comparator from Texas Instruments featuring an integrated 2.5V voltage reference with 1.5% accuracy and 100ppm/°C drift. It operates within a wide supply range of 3.3V to 65V, supporting fail-safe inputs up to 65V and open-drain outputs rated for 65V. Key electrical specifications include a maximum input offset voltage of 500µV, input bias current of 2pA, and quiescent current of 8µA per channel. The device supports output currents of 1mA and functions across a temperature range of -40°C to +125°C.

Comparators Feature Summary

• Integrated 2.5V voltage reference with high stability
• Wide supply voltage range up to 65V
• Fail-safe input capability for robust operation
• Open-drain output structure compatible with various logic levels

Comparators Applications

• High-voltage signal monitoring systems
• Industrial process control interfaces
• Battery management system threshold detection
• Over-voltage protection circuits

Comparators Procurement Notes

Verify the complete part number including the suffix 'DSGR' to ensure correct packaging in WSON-8 tape and reel format. Confirm that the 2.5V internal reference meets your specific accuracy requirements, as this feature distinguishes it from standard comparators. Ensure design compatibility with the 65V maximum ratings for both supply and input signals to prevent device damage during operation.

Comparators Selection Notes

Select this component when a precise internal reference is required alongside high-voltage tolerance. The low input bias current and offset voltage make it suitable for high-impedance sensor interfaces. Consider the open-drain output requirement for pull-up resistor implementation. Verify that the 8µA quiescent current aligns with power budget constraints compared to higher-speed alternatives.

Comparators Part Context

This device belongs to the TLV192x family of comparators designed for high-voltage applications. Unlike standard comparators requiring external references, the TLV1922 integrates a stable 2.5V source, reducing component count. The WSON-8 package provides a compact footprint for space-constrained designs while maintaining thermal performance suitable for industrial environments.

Comparators Replacement Considerations

Direct substitutes within the TLV192x family include the TLV1921 (single channel) or TLV1924 (quad channel) if pin compatibility allows. Verify that alternative parts maintain the 65V rating and integrated reference specification. Cross-reference datasheets for propagation delay differences if timing sensitivity is critical.
