Overview
The TS862AIDT is a dual analog comparator from STMicroelectronics, part of the TS86x family. It operates on a supply voltage range of 2.7 V to 10 V and functions within a temperature range of -40 °C to +85 °C. The device features rail-to-rail CMOS inputs and push-pull outputs, consuming 6 μA per comparator at 2.7 V. It exhibits a response time of 2 μs and an input offset voltage of 15 mV. The component is housed in an SOIC-8 surface-mount package.
Feature Summary
- Rail-to-rail CMOS inputs enable full signal swing capability across the supply range.
- Push-pull output stage allows direct connection to microcontrollers without external pull-up resistors.
- Ultra-low current consumption supports extended battery life in portable applications.
Applications
- Battery-powered systems requiring low power consumption
- Microcontroller interface circuits
- Signal conditioning applications
Procurement Notes
Verify the specific suffix 'DT' corresponds to the SOIC-8 tape and reel packaging configuration as documented in official STMicroelectronics datasheets. Confirm that the 'AI' designation aligns with the required industrial temperature range and electrical specifications for the target application environment before finalizing procurement.
Selection Notes
Select this component when a dual-channel comparator with rail-to-rail input/output capabilities is required. It is suitable for designs needing low propagation delay and minimal quiescent current. Ensure the system voltage remains within the 2.7 V to 10 V operational limits and that the SOIC-8 package fits the board layout constraints.
Part Context
This device belongs to the TS86x series, which includes single (TS861), dual (TS862), and quad (TS864) variants. All members share similar electrical characteristics, including ultra-low power consumption and rail-to-rail operation, allowing for flexible design scaling based on channel count requirements while maintaining consistent performance profiles.
Replacement Considerations
Compatible alternatives include the TS861AIDT for single-channel applications and the TS864AIDT for four-channel requirements. Other packages such as TSSOP-8 may be considered if pin compatibility and thermal performance are verified against the SOIC-8 footprint.
