TS862AIN

Overview

The TS862AIN is a dual analog comparator from the TS86x family, manufactured by STMicroelectronics. It utilizes MicroPwr BiCMOS technology and features rail-to-rail CMOS inputs with push-pull outputs. The device operates within a supply voltage range of 2.7 V to 10 V and consumes 6 μA per comparator at 2.7 V. It offers a response time of 500 ns at 2.7 V for a 100 mV overdrive. The input offset voltage is 15 mV, and the input bias current is 300 pA. It supports a maximum output current of 5 mA per channel and dissipates up to 625 mW. The component functions reliably across an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Rail-to-rail CMOS inputs enable full signal swing compatibility.
• Push-pull output stage allows direct microcontroller interfacing without pull-up resistors.
• Ultra-low power consumption of 6 μA per comparator optimizes battery life.
• Integrated ESD protection (2 kV) and Class A latch-up immunity enhance reliability.

Applications

• Battery-powered portable systems
• Industrial sensor interfaces
• Smart home devices

Procurement Notes

Verify the specific suffix 'AIN' against official datasheets to confirm package type and temperature grade. Ensure the ordering code matches the required TSSOP-8 or SOIC-8 configuration. Confirm RoHS compliance status directly with the manufacturer documentation before procurement.

Selection Notes

Select this component for applications requiring low power consumption and rail-to-rail input capability. The push-pull output simplifies circuit design by eliminating external pull-up resistors. Consider the 500 ns propagation delay for speed-sensitive designs. Verify that the 2.7 V minimum supply voltage aligns with system requirements.

Part Context

The TS862AIN belongs to the TS86x family, which includes single, dual, and quad comparators. This family is characterized by excellent speed-to-power ratios and availability in compact packages such as SOT23-5, SO-8, and TSSOP-8. The series is designed for efficient operation in battery-powered environments.

Replacement Considerations

Check for other members of the TS86x family, such as TS862IDT or TS862IPT, which share identical electrical characteristics but differ in package style. Verify pinout compatibility when substituting between different package types within the same series.
