Overview
The ADCMP343YRJZ-REEL7 is a dual precision 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 two inverting comparators with open-drain outputs capable of sinking up to 40 mA. Hysteresis is user-programmable via an external three-resistor string connected to the ±INx_U and ±INx_L pins. Input bias current is limited to 5 nA maximum, and propagation delay is 10 µs at 5 V.
Feature Summary
- Dual inverting comparators with a built-in 400 mV reference
- User-programmable hysteresis using an external resistor string
- Open-drain outputs supporting wired-AND connections
- Low power consumption suitable for portable applications
Applications
- Portable applications
- Li-Ion monitoring
- Handheld instruments
- LED/relay driving
- Control systems
Procurement Notes
Verify the specific ordering suffix REEL7 corresponds to tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the component matches the exact Analog Devices part number to guarantee compatibility with design specifications and performance characteristics.
Selection Notes
Select this component for low-voltage systems requiring precise threshold detection without external references. The inverting configuration suits applications where output state changes upon input exceeding the reference. Consider the open-drain output requirement for pull-up resistors and verify that the programmable hysteresis network fits within available board space and noise immunity requirements.
Part Context
This device belongs to the ADCMP341/ADCMP343 family from Analog Devices. The ADCMP343 variant specifically provides inverting inputs, whereas the ADCMP341 offers noninverting inputs. Both share identical electrical characteristics, package options, and internal reference structures, differing only in input polarity configuration for system integration flexibility.
Replacement Considerations
The ADCMP341YRJZ-REEL7 serves as a functional substitute if noninverting logic is acceptable. Verify pinout compatibility and ensure the application does not strictly require the inverting signal path provided by the ADCMP343.
