MAX1309ECM/V+

Analog To Digital Converters (ADC) Overview

The MAX1309ECM/V+ is a 12-bit, four-channel simultaneous-sampling analog-to-digital converter (ADC) from the MAX1304–MAX1314 family. It features independent track-and-hold circuitry for each channel and accepts ±5V analog input signals with ±16.5V fault tolerance. The device operates from a +4.75V to +5.25V analog supply and a +2.7V to +5.25V digital supply, consuming 57mA total current. It provides an 8-bit bidirectional parallel data bus and supports internal or external clocking. Key performance metrics include a maximum throughput of 901ksps per channel when two channels are selected, a typical signal-to-noise ratio of 71dB, and a 20MHz small-signal bandwidth.

Analog To Digital Converters (ADC) Feature Summary

• Four independent input channels with simultaneous sampling capability
• ±5V extended analog input range with high fault tolerance
• Internal or external reference voltage options
• Bidirectional parallel interface with tri-state outputs

Analog To Digital Converters (ADC) Applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'V+' against the manufacturer's official documentation to confirm package type and lead-free status. Ensure the component matches the required ±5V input range specification. Cross-reference the part number with the latest datasheet revision to confirm availability and compliance with RoHS standards before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four-channel simultaneous sampling is required with a ±5V input range. Verify that the system requires a parallel interface and can accommodate the specified power supply voltages. Consider the thermal dissipation requirements given the 1818.2mW continuous power dissipation limit in the LQFP package.

Analog To Digital Converters (ADC) Part Context

This device belongs to the MAX1304–MAX1314 series of 12-bit ADCs. While other members offer eight or two channels, or different input ranges like 0 to +5V or ±10V, the MAX1309 specifically targets applications needing four bipolar channels. It shares the same 48-pin LQFP footprint and core architecture as its siblings.

Analog To Digital Converters (ADC) Replacement Considerations

Compatible substitutes within the same family include the MAX1308ECM+ (eight channels, ±5V range) and the MAX1310ECM+ (two channels, ±5V range). These parts share identical pinouts and electrical characteristics but differ only in the number of available analog input channels.
