MX7576JN+

Analog To Digital Converters (ADC) Overview

The MX7576JN+ is an 8-bit successive-approximation analog-to-digital converter (ADC) from Analog Devices/Maxim Integrated. It operates on a single +5V supply and utilizes a 1.23V external reference, accepting input voltages from 0V to 2VREF. The device features a 10µs conversion time with an internal clock or external clock inputs up to 2MHz. It includes latched, three-state CMOS data outputs for direct microprocessor interfacing. Key electrical parameters include a signal-to-noise ratio of 45dB, ±1LSB total unadjusted error, and 15mW power dissipation.

Analog To Digital Converters (ADC) Feature Summary

• 10µs conversion time using SAR technique
• Single +5V supply operation with 15mW power dissipation
• Latched, three-state 8-bit parallel data outputs
• ±1LSB maximum total unadjusted error

Analog To Digital Converters (ADC) Applications

• Digital Signal Processing
• High-Speed Data Acquisition
• Telecommunications
• Audio Systems
• Low-Power Data Loggers

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix JN against current manufacturer documentation to confirm package type and temperature range. Confirm availability status as older Maxim products may have limited distribution channels. Ensure the required 1.23V external reference voltage source is compatible with the REF pin specifications before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the MX7576JN+ when a 10µs conversion speed is sufficient, distinguishing it from the faster MX7575 variant which offers 5µs conversion. This model requires an external reference voltage rather than an internal one. Ensure the application supports parallel microprocessor interfaces with CS, RD, and BUSY control signals for proper data acquisition timing.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MX7575/MX7576 family of high-speed, microprocessor-compatible 8-bit ADCs. The MX7576 specifically lacks the built-in track/hold function found in the MX7575 but samples the input eight times during conversion. It is designed for applications requiring low power consumption and direct interface to standard 8-bit microprocessors.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX165 is documented as a plug-in replacement for the MX7575, not the MX7576. For differential input requirements with an internal reference, the MAX166 is recommended. No direct MX7576 equivalent with internal reference is explicitly listed in the provided text.
