Overview
The LMV7235M7 is a single-channel analog comparator from Texas Instruments, housed in a SC-70-5 (SOT-353) surface-mount package. It operates on a single supply voltage ranging from 2.7 V to 5.5 V with a typical quiescent current of 95 µA. The device features rail-to-rail input capability and an open-drain output configuration. Key electrical specifications include a maximum propagation delay of 75 ns, a maximum input offset voltage of 6 mV at 5 V, and a maximum input bias current of 400 nA. It supports a wide operating temperature range from -40 °C to +85 °C.
Feature Summary
- Rail-to-rail input stage allows signal detection across the full supply voltage range.
- Open-drain output architecture provides flexibility for interfacing with various logic families.
- Ultra-low power consumption suitable for battery-operated applications.
Applications
- Battery-powered portable electronics
- Threshold detection circuits
- General-purpose voltage monitoring
Procurement Notes
Verify the specific suffix 'M7' corresponds to the SC-70-5 package variant when sourcing. Confirm RoHS compliance status as indicated by the NOPB designation. Ensure the supplier documentation matches the Texas Instruments datasheet for the LMV7235 series to validate electrical parameters such as propagation delay and offset voltage.
Selection Notes
Select this component when a low-power, single-supply comparator with rail-to-rail inputs is required. The open-drain output necessitates an external pull-up resistor; ensure the selected resistor value aligns with the target switching speed and load requirements. Consider the SC-70-5 package size constraints during PCB layout.
Part Context
The LMV7235 belongs to the LMV723x family of ultra-low power comparators designed for space-constrained, battery-driven systems. It offers a trade-off between speed and power, providing nanosecond-level response times while maintaining microampere-level current draw. This family is distinct from higher-speed or precision comparator lines within the manufacturer's portfolio.
Replacement Considerations
Check for pin-compatible alternatives within the same family, such as variants with push-pull outputs if open-drain is unsuitable. Verify that any substitute maintains the 2.7 V minimum supply voltage and SC-70-5 footprint.
