Overview
The TS862AIPT 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 only 6 μA per comparator at 2.7 V. It exhibits a response time of 2 μs, an input offset voltage of 15 mV, and an input bias current of 300 pA. Each channel provides an output current of 5 mA. The component is housed in an 8-pin TSSOP package.
Feature Summary
- Rail-to-rail CMOS inputs enable full signal swing compatibility across the supply range.
- Push-pull output stage allows direct connection to microcontrollers without external pull-up resistors.
- Ultra-low power consumption supports extended operation in battery-powered systems.
Applications
- Battery-powered portable electronic devices
- Microcontroller interface circuits
- Signal conditioning applications
Procurement Notes
Verify the specific suffix 'AI' indicates the industrial temperature grade (-40 °C to +85 °C) and performance class as defined by STMicroelectronics documentation. Confirm the TSSOP-8 package marking matches the required board layout. Ensure ESD handling protocols are followed during assembly due to the CMOS input structure.
Selection Notes
Select this component when low power consumption is critical alongside the need for rail-to-rail input capability. The push-pull output simplifies design by eliminating pull-up resistors. Compare against single-channel (TS861) or quad-channel (TS864) variants if pin count or channel density requirements differ. Verify that the 2 μs response time meets the system's speed requirements.
Part Context
The TS862AIPT belongs to the TS86x series of rail-to-rail micropower BiCMOS comparators. This family includes single, dual, and quad configurations sharing similar electrical characteristics. The series is designed for high speed-to-power ratios, making it suitable for applications requiring efficient energy usage without sacrificing switching performance.
Replacement Considerations
Check for other members of the TS86x family such as TS861 or TS864 for different channel counts. Verify availability of alternative packages like SO-8 or SOT23-5 if form factor changes are permissible. Cross-reference with other low-power dual comparators ensuring push-pull outputs and compatible supply voltages.
