LT1011CS8#PBF

Overview

The LT1011CS8#PBF is a general-purpose voltage comparator manufactured by Analog Devices Inc. in an 8-lead SOIC package with a commercial temperature range of 0°C to 70°C. It features a maximum input offset voltage of 0.5mV, a guaranteed maximum response time of 250ns, and a minimum large-signal voltage gain of 200,000 V/mV. The device supports single or dual supply operation from 3V to ±18V, providing a 50mA output current source or sink capability.

Feature Summary

• Pin compatible with LM111 series devices while offering significantly improved input characteristics
• Guaranteed low input bias current and offset voltage drift for high precision applications
• Floating transistor output capable of driving loads referenced to ground, negative, or positive supplies

Applications

• SAR A/D Converters
• Voltage-to-Frequency Converters
• Precision RC Oscillators
• Motor Speed Control
• Relay/Lamp Drivers

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm lead-free finish status and RoHS compliance requirements against project specifications. Ensure the supplier provides valid traceability documentation for the Analog Devices Inc. manufacturer part number.

Selection Notes

Select this component when pin compatibility with legacy LM111 designs is required alongside superior speed and accuracy. Consider the floating output architecture for flexible load referencing. Evaluate the single 5V supply specification if operating in low-voltage environments without negative rails.

Part Context

This part belongs to the LT1011 family of general-purpose voltage comparators. It retains the versatile features of the LM111 but offers faster response times under large overdrive conditions and lower power consumption. The device is fully specified for DC parameters and response time across its operating temperature range.

Replacement Considerations

LM111 series devices are pin-compatible alternatives.
