MAX1090AEEI+T

Analog To Digital Converters (ADC) Overview

The MAX1090AEEI+T is a low-power, 10-bit analog-to-digital converter (ADC) featuring a successive-approximation architecture. It operates with a single +5V analog supply and includes an on-chip clock, a +2.5V internal reference, and a byte-wide parallel interface. The device supports software-configurable unipolar/bipolar and single-ended/pseudo-differential analog inputs. In single-ended mode, it provides eight input channels, while pseudo-differential mode offers four channels. Power consumption is 10mW at the maximum sampling rate of 400ksps. Two software-selectable power-down modes allow current to drop below 10µA between conversions.

Analog To Digital Converters (ADC) Feature Summary

• Successive-approximation ADC architecture with automatic power-down and fast wake-up capabilities
• Software-configurable analog input multiplexer supporting single-ended and pseudo-differential modes
• Internal +2.5V reference with user-adjustable logic level ranging from +2.7V to +5.5V
• Byte-wide parallel interface for direct connection to standard microprocessors

Analog To Digital Converters (ADC) Applications

• Industrial Control Systems
• Data Logging
• Energy Management
• Patient Monitoring
• Touchscreens

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range of -40°C to +85°C. Confirm the '+T' designation corresponds to tape-and-reel packaging as specified in the manufacturer's ordering information. Ensure compatibility with the 28-pin QSOP package dimensions before integration into the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution with 400ksps sampling rate is required alongside low power consumption. The MAX1090 variant is appropriate for designs needing eight single-ended or four pseudo-differential channels. Consider the internal reference and clock features if minimizing external component count is a priority.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1090/MAX1092 family of 10-bit ADCs. The MAX1090 specifically provides eight input channels compared to the four-channel MAX1092. Both devices share identical electrical characteristics and pinouts, differing only in channel count and package size. The MAX1090 is housed in a 28-pin QSOP package.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1091/MAX1093 are pin-compatible +3V versions of this device. For tri-stating INT functionality not desired, refer to the MAX1060/MAX1064 data sheet.
