LT1011CS8#TRPBF

Overview

The LT1011CS8#TRPBF is a general-purpose voltage comparator manufactured by Analog Devices Inc. It features an 8-lead Plastic SO package and operates within a temperature range of 0°C to 70°C. Key electrical specifications include a maximum input offset voltage of 0.5mV, a maximum input bias current of 25nA, and a guaranteed minimum voltage gain of 200,000 V/mV. The device supports single or dual supply operation from 3V to ±18V (up to 36V total) and provides a floating open-collector output capable of sourcing or sinking 50mA. Response time is guaranteed at a maximum of 250ns.

Feature Summary

Pin compatible with LM111 series devices while offering significantly improved input characteristics including lower bias current and offset voltage.
Features a floating transistor output that allows driving loads referenced to ground, negative supply, or positive supply independently.
Includes a dedicated strobe pin to force the output transistor into an off state for precise timing control.
Fully specified for DC parameters and response time when operating on a single 5V supply.

Applications

SAR A/D Converters
Voltage-to-Frequency Converters
Precision RC Oscillators
Peak Detectors
Motor Speed Control

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging rather than tube. Confirm the C grade corresponds to the commercial 0°C to 70°C temperature range. Ensure the 8-lead SO package dimensions match the PCB footprint requirements. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm lead-free finish status.

Selection Notes

Select this component when high speed and low offset are required in a standard SOIC package. Consider the LT1011CN8#PBF variant if through-hole mounting is necessary. Evaluate the need for the strobe functionality versus simpler comparator applications. Verify that the 50mA output current capability meets the load drive requirements without external buffering.

Part Context

This component belongs to the LT1011 family of precision voltage comparators designed as direct replacements for legacy LM111 devices. The CS8 designation identifies the commercial temperature grade and surface-mount plastic small outline package configuration. The TRPBF suffix denotes the specific tape and reel shipping format with lead-free termination.
