Overview
The LMV393IDGKR is a dual general-purpose analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and features an open collector/open drain output type. The device includes two channels with a typical response time of 200 ns and a maximum propagation delay of 600 ns. Input characteristics include a maximum input offset voltage of 7 mV and a maximum input bias current of 250 nA. It functions reliably across a temperature range of -40°C to +125°C and is housed in an 8-VSSOP package.
Feature Summary
- Dual-channel architecture for general-purpose signal comparison
- Low-voltage operation compatible with single or dual power supplies
- Open collector/drain output configuration for flexible interfacing
- Extended industrial temperature range capability
Applications
- General-purpose voltage monitoring circuits
- Threshold detection systems
- Simple logic interface adapters
- Battery-powered low-voltage applications
Procurement Notes
Verify the specific suffix 'DGKR' corresponds to the 8-VSSOP package and tape-and-reel packaging format. Confirm RoHS compliance status and ensure the operating temperature range meets the application's environmental requirements. Cross-reference the manufacturer part number with authorized distributor databases to validate authenticity and current production status before finalizing procurement orders.
Selection Notes
Select this component when a dual comparator with low supply voltage requirements is needed. The open-drain output allows for wired-AND configurations or level shifting. Ensure the input common-mode voltage range, which extends slightly below ground, aligns with the signal source characteristics. Consider the 8-VSSOP package size constraints during PCB layout planning.
Part Context
This part belongs to the LMV series of low-voltage comparators from Texas Instruments. It shares functional similarities with other members like the LMV339 but offers a dual-channel configuration in a compact surface-mount package. The device is designed for cost-sensitive applications requiring reliable performance in low-power environments.
Replacement Considerations
The LMV393IDGKR is functionally interchangeable with the LMV393IDGKT. Verify pinout compatibility and package dimensions when substituting. Other family members such as the LMV393QDRQ1 offer automotive qualification but differ in package style.
