MAX1067AEEE+T

Analog To Digital Converters (ADC) Overview

The MAX1067AEEE+T is a low-power, multichannel, 14-bit analog-to-digital converter (ADC) featuring a successive-approximation architecture. It operates with a single +5V analog supply and a separate digital supply ranging from +2.7V to +5.5V. The device includes an integrated +4.096V reference, a reference buffer, an internal oscillator, and automatic power-down capabilities. It supports SPI/QSPI/MICROWIRE-compatible interfaces and features a 4-channel input multiplexer. Key electrical parameters include a maximum sample rate of 200ksps, ±0.5 LSB INL, ±1 LSB DNL, and a typical SNR of 84 dB at 200ksps.

Analog To Digital Converters (ADC) Feature Summary

• Integrated +4.096V reference with external reference support
• Multichannel input multiplexer for sequential or continuous scanning
• Automatic power-down modes for optimized energy efficiency
• High-speed serial interface compatible with standard protocols

Analog To Digital Converters (ADC) Applications

• Motor Control
• Industrial Process Control
• Data-Acquisition Systems
• Thermocouple Measurements
• Accelerometer Measurements

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'EEE' confirms the extended temperature range (-40°C to +85°C). Confirm the '+T' designation indicates tape-and-reel packaging versus tube options. Cross-reference the manufacturer's current lifecycle status as older Maxim Integrated products may have limited availability or require alternative sourcing strategies.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit resolution and 200ksps throughput are required in a compact form factor. Ensure the application can accommodate the +5V analog supply while utilizing a lower voltage digital logic level. Verify that the 4-channel multiplexer meets the input requirements, as the MAX1068 variant offers eight channels if more inputs are needed.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1067/MAX1068 family of multichannel ADCs manufactured by Analog Devices/Maxim Integrated. The MAX1067 variant specifically provides four analog inputs, whereas the MAX1068 expands this to eight channels. Both share identical core conversion performance and interface characteristics within the same package families.

Analog To Digital Converters (ADC) Replacement Considerations

MAX1067BEEE+T: Offers ±1 LSB INL instead of ±0.5 LSB.

Analog To Digital Converters (ADC) FAQ

What is the acquisition time for the MAX1067AEEE+T?

The acquisition time is calculated using the formula tACQ = 11(RS + RIN + RDS(ON)) × 45pF + 0.3µs, where RIN is 340 Ω and RDS(ON) is 60 Ω. The minimum acquisition time is 729 ns.

How does the device handle power consumption during idle periods?

Driving the CS pin high places the device in shutdown mode, reducing the supply current to a typical value of 0.6 µA. Software-programmable power-down options are also available in internal reference mode.

Can the MAX1067AEEE+T interface directly with 3.3V logic?

Yes, the digital supply (DVDD) accepts voltages from +2.7V to +5.5V, allowing direct interfacing with 3.3V digital logic systems while maintaining a separate +5V analog supply.
