JTS393C-1AA5

Overview

The JTS393C-1AA5 is a micropower dual CMOS voltage comparator provided as an unsawn wafer. It operates within a supply voltage range of 2.7 V to 16 V or dual supplies from ±1.35 V to ±8 V. The device features extremely low input bias and offset currents, typically 1 pA each. Input common-mode voltage includes ground, with high input impedance of 10^12 Ω typical. Response time is 2.5 µs typical for 5 mV overdrive. Operating temperature range is 0 °C to +70 °C.

Feature Summary

• Micropower CMOS dual voltage comparator architecture
• Extremely low input bias and offset currents
• Wide single and dual supply voltage operation
• Functionally compatible with bipolar LM393

Applications

• Battery-powered systems requiring low consumption
• Signal conditioning circuits
• Threshold detection applications

Procurement Notes

Verify the specific ordering code JTS393C-1AA5 against current STMicroelectronics documentation to confirm availability and specifications. Ensure that the unsawn wafer format aligns with your manufacturing capabilities for die attachment and wire bonding. Confirm that the industrial temperature range meets your system requirements.

Selection Notes

Select this component when a dual comparator with ultra-low power consumption is required in a wafer form factor. It serves as a direct functional replacement for the LM393 in designs where space and power are constrained. Consider the TS393 if a plastic packaged version is needed instead of bare die.

Part Context

This part belongs to the JTS393 series of micropower CMOS comparators. It is the unsawn wafer version of the TS393, which is available in plastic packages. The device offers performance similar to the industry-standard LM393 but with significantly lower power consumption.

Replacement Considerations

The TS393 is the plastic packaged equivalent. For push-pull output variants, consider the TS3702 or JTS3702.
