Overview
The LM293AN is a dual voltage comparator manufactured by onsemi, housed in an 8-pin PDIP package. It features two independent comparators with a maximum input offset voltage of 4000 µV and a response time of 1300 ns. The device operates within a temperature range of -25 °C to 85 °C and utilizes bipolar technology.
Feature Summary
- Dual independent comparator architecture
- Bipolar process technology
- Plastic DIP-8 packaging
Applications
Procurement Notes
Verify the RoHS compliance status as the source indicates non-compliance. Confirm the manufacturer origin, noting Philips Semiconductors attribution in some records versus onsemi branding. Ensure the specific ordering suffix matches the required PDIP-8 package and lead frame material specifications for your assembly process.
Selection Notes
Select this component when a standard dual comparator in a through-hole DIP-8 package is required. Consider the 4000 µV maximum offset voltage and 1300 ns response time against application speed and precision needs. Verify that the bipolar technology and plastic package are suitable for the target environmental conditions.
Part Context
This part belongs to the LM293 series of low-power dual voltage comparators. These devices are designed for single or split supply operation. The LM293AN specifically denotes the through-hole PDIP-8 variant, distinct from surface-mount options like SOIC or TSSOP found in the broader family.
Replacement Considerations
LM393 variants offer similar functionality but may differ in offset voltage and temperature ranges. LM2903 provides improved performance characteristics. Verify pinout compatibility and electrical parameter alignment before substitution.
