LT1016IS8#PBF

Overview

The LT1016IS8#PBF is a single-channel ultra-fast precision comparator manufactured by Analog Devices Inc. It operates on a single 5V supply or ±5V dual supplies within an 8-lead plastic SO package. The device features complementary outputs compatible with TTL and CMOS logic, ensuring direct interfacing without additional buffering. Key electrical specifications include a typical propagation delay of 9ns to 14ns, an input offset voltage of 1mV, and a common mode rejection ratio of 96dB. It draws 25mA from the positive supply and 3mA from the negative supply, supporting high-speed applications requiring precise signal discrimination.

Feature Summary

• Ultra-fast response time with minimal propagation delay for high-speed signal processing
• Complementary output stage providing active drive in both directions for stable operation
• Integrated latch capability to retain input data at the outputs when enabled
• Operates directly with TTL and CMOS logic levels using single or dual power supplies

Applications

• High-speed A/D converters
• Crystal oscillators operating between 10MHz and 25MHz
• Zero-crossing detectors
• Fast pulse height and width discriminators
• Current sense circuits for switching regulators

Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and RoHS compliance as per manufacturer standards. Confirm the IS8 designation corresponds to the industrial temperature range of -40°C to +85°C and the 8-lead SOIC package. Ensure the ordering information matches the required tape and reel or tube packaging options available through designated sales channels. Cross-reference the datasheet revision D specifications for accurate electrical limits.

Selection Notes

Select this component when nanosecond-level response times are critical for circuit performance. The low input offset voltage makes it suitable for precision applications where small differential signals must be accurately detected. Consider the complementary output configuration if driving both high and low logic states efficiently is required. Evaluate the power supply requirements, as the device supports both single 5V and ±5V configurations, offering flexibility in system design.

Part Context

FAQ

How does the LATCH pin function?

The LATCH pin retains input data at the outputs when held high. To guarantee data retention, the input signal must be valid at least 5ns before the latch goes high and remain valid for at least 3ns after.

What is the common mode input voltage range?

With ±5V supplies, the common mode range is -3.75V to 3.5V. Generally, the range is 1.25V above the negative supply and 1.5V below the positive supply.
