MAX913CSA

Overview

The MAX913CSA is a single-channel, ultra-fast, low-power precision comparator manufactured by Analog Devices Inc./Maxim Integrated. It features differential inputs and complementary TTL outputs, designed for high-speed applications requiring minimal power consumption. The device operates from a single +5V or dual ±5V supply, with an input common-mode range that extends below the negative rail. Key electrical characteristics include a typical propagation delay of 10ns, an input offset voltage of 0.8mV, and a supply current of 6mA per comparator at +5V. It is housed in an 8-pin SO package and functions within a temperature range of 0°C to +70°C.

Feature Summary

• Ultra-fast response with typical 10ns propagation delay
• Low power consumption with 6mA supply current per comparator
• Stable operation in the linear region without oscillation
• Input range extends below the negative supply rail

Applications

• Zero-Crossing Detectors
• Switching Regulators
• High-Speed Sampling Circuits
• Fast Pulse Width/Height Discriminators

Procurement Notes

Verify the specific suffix CSA indicates the 8-pin Small Outline (SO) package variant with a commercial temperature range of 0°C to +70°C. Confirm compatibility with single +5V or dual ±5V supply requirements. Ensure board layout adheres to high-speed component guidelines, including short leads and unbroken ground planes, to minimize parasitic inductance and capacitance during procurement and integration.

Selection Notes

Select the MAX913CSA when a single comparator channel is required with TTL-compatible outputs. It serves as an improved plug-in replacement for the LT1016, offering wider input voltage range and equivalent speed at lower power. Choose this part over the MAX912 if only one channel is needed, as the MAX912 provides dual channels with independent latch controls but requires a 16-pin package.

Part Context

The MAX913 is part of the MAX912/MAX913 family of high-speed, low-power comparators. While the MAX912 offers dual channels, the MAX913 provides a single channel in a compact 8-pin package. This family is characterized by its ability to operate stably in the linear region without hysteresis, making it suitable for precision applications where resolution is critical. The CS designation specifically denotes the SOIC package option within the commercial temperature grade.

Replacement Considerations

The MAX913 is documented as an improved plug-in replacement for the LT1016, providing significantly wider input voltage range and equivalent speed at a fraction of the power.
