Overview
The ADCMP341YRJZ-REEL7 is a dual precision analog comparator with an integrated 400 mV reference, housed in an 8-lead SOT-23 package. It operates within a supply voltage range of 1.7 V to 5.5 V and draws a typical quiescent current of 6.5 µA. The device features open-drain outputs capable of sinking up to 40 mA and supports wired-AND connections. Input bias current is limited to ±5 nA maximum, and the threshold voltage accuracy is ±0.275% at 25°C. Propagation delay is specified at 10 µs for high-to-low transitions.
Feature Summary
- Features user-programmable hysteresis via an external three-resistor string configuration connected to dedicated input pins.
- Includes an internal 400 mV reference with high accuracy for precise threshold detection.
- Supports wired-AND logic through open-drain outputs with guaranteed sink capability.
- Input range includes ground potential, facilitating low-voltage system monitoring.
Applications
- Portable applications
- Li-Ion battery monitoring
- Handheld instruments
- LED and relay driving
- Control systems
Procurement Notes
Verify component authenticity by checking manufacturer markings against the ordering guide. Confirm RoHS compliance status as indicated by the suffix. Ensure the specific variant matches the required input polarity (noninverting for ADCMP341). Validate that the operating environment stays within the specified temperature and voltage limits to maintain performance specifications.
Selection Notes
Select this component for designs requiring low power consumption and high threshold accuracy without external references. The open-drain output requires an external pull-up resistor; ensure the resistor value aligns with desired rise times and load conditions. Consider the programmable hysteresis feature to mitigate noise sensitivity in signal paths where input signals may exhibit slow transitions or interference.
Part Context
This part belongs to the ADCMP341/ADCMP343 family of dual comparators. The ADCMP341 variant provides noninverting inputs, while the ADCMP343 offers inverting inputs. Both share identical electrical characteristics and packaging. The YRJZ suffix denotes an 8-lead SOT-23 package with industrial temperature range coverage and RoHS compliance.
Replacement Considerations
The ADCMP343YRJZ-REEL7 serves as a functional substitute if inverting comparator inputs are required instead of noninverting ones. Other members of the ADCMP34x series may be considered if pin compatibility and electrical parameters align with the design requirements.
FAQ
How is hysteresis programmed on the ADCMP341?
Hysteresis is set using a three-resistor string connected to the ±INA_U and ±INA_L pins. The comparator output switches between these pins via an internal multiplexer to create distinct rising and falling trip points.
What is the maximum output sink current?
The open-drain outputs are capable of sinking up to 40 mA, allowing them to drive loads directly or support wired-AND configurations.
