LT1016CH

Overview

The LT1016CH is a precision voltage comparator manufactured by Analog Devices Inc. It features ultra-fast response times with a typical propagation delay of 10 nanoseconds. The device operates from single 5V or dual ±5V power supplies and provides complementary outputs compatible with TTL and CMOS logic levels. Key electrical characteristics include a maximum input offset voltage of 3.5mV, an input bias current of 13µA, and a quiescent negative supply current of only 3mA. The part includes a latch enable pin for data retention and is housed in an 8-lead plastic SO package.

Feature Summary

• Ultra-fast 10ns propagation delay for high-speed signal processing
• Complementary outputs directly interface with TTL/CMOS logic
• Low offset voltage ensures precision in differential measurements
• Latch capability retains input data at the outputs when enabled

Applications

• High-speed analog-to-digital converters
• Zero-crossing detectors
• Fast pulse height and width discriminators
• Crystal oscillators operating between 10MHz and 25MHz

Procurement Notes

Verify the specific suffix 'CH' against official Analog Devices documentation to confirm availability and exact temperature range specifications. Standard commercial variants are designated as LT1016C. Ensure the selected component matches the required operating temperature range and package type for your design constraints.

Selection Notes

Select this comparator for applications requiring fast response times and precision without minimum input slew rate requirements. Consider the low negative supply current if designing with asymmetric power rails. Verify that the output drive capabilities meet the load requirements of the downstream TTL or CMOS circuitry.

Part Context

The LT1016 belongs to the UltraFast comparator family from Analog Devices. It is designed to replace older high-speed comparators while offering improved stability and lower power consumption. The device is notable for its ability to remain stable in the linear region, reducing output glitching during slow-moving input signals.

FAQ

Does the LT1016 require a minimum input slew rate?

No, the LT1016 does not have a minimum input slew rate requirement, allowing it to respond accurately to slow-moving or low-level signals.

How does the LATCH pin function?

Holding the LATCH pin high retains the input data at the outputs. To guarantee data retention, the input signal must be valid for at least 5ns before the latch goes high.
