Overview
The LM393LVDGKR is a single-channel low-voltage analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and features an open-drain output compatible with CMOS and TTL logic families. The device exhibits a propagation delay of 600 ns, a maximum input offset voltage of 3 mV, and a typical quiescent current of 50 uA. It supports rail-to-rail input operation and maintains functionality across an extended temperature range from -40 C to +125 C.
Feature Summary
- Supports ultra-low voltage operation down to 1.65 V for battery-powered applications
- Features rail-to-rail input capability for maximum dynamic range
- Provides open-drain output for flexible logic level interfacing
Applications
- Low-voltage signal conditioning circuits
- Battery-operated monitoring systems
- Portable electronic devices requiring minimal power consumption
Procurement Notes
Verify the specific suffix DGKR corresponds to the VSSOP-8 package and tape-and-reel quantity when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 1.65 V minimum supply requirement and check for any recent product change notices affecting assembly sites or materials.
Selection Notes
Select this component for designs prioritizing low quiescent current and wide input common-mode range in sub-5V environments. Compare against standard LM393 variants if higher supply voltages or dual-channel configurations are required. Validate that the single-channel architecture meets the system's channel count requirements without necessitating additional components.
Part Context
This part belongs to the LM393LV series, designed specifically for low-voltage applications compared to the standard LM393 family. It utilizes a VSSOP-8 surface-mount package suitable for space-constrained PCB layouts. The device serves as a specialized alternative for portable electronics where power efficiency and low supply voltage operation are critical design constraints.
