MAX1090BEEI+

Analog To Digital Converters (ADC) Overview

The MAX1090BEEI+ is a low-power, 10-bit analog-to-digital converter (ADC) featuring a successive-approximation register (SAR) architecture. It operates with a single +5V analog supply and supports a digital logic supply ranging from +2.7V to +5.5V via the VLOGIC pin. The device includes an on-chip clock, a +2.5V internal reference, and a byte-wide parallel interface. It offers software-configurable analog inputs for unipolar/bipolar and single-ended/pseudo-differential operation, providing eight input channels in single-ended mode or four in pseudo-differential mode. Power consumption is 10mW at a maximum sampling rate of 400ksps, with two software-selectable power-down modes reducing current to under 10µA.

• Software-configurable analog input multiplexer supporting single-ended and pseudo-differential modes
• Byte-wide parallel interface compatible with standard microprocessors

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix EEI corresponds to the -40°C to +85°C temperature range and 28-pin QSOP package. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering information matches the exact part number variant required for the application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution with up to 400ksps sampling rate is required in a space-constrained design. The integrated reference and clock simplify circuit layout compared to external reference solutions. Consider the parallel interface requirements and ensure the host system can accommodate the 8-bit data bus width and control signals.

Analog To Digital Converters (ADC) Part Context

The MAX1090BEEI+ belongs to the MAX1090/MAX1092 family of low-power ADCs. It is pin-compatible with the MAX1092, which features four channels instead of eight. For +3V operation, the MAX1091/MAX1093 series serves as a related alternative within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1090ACEI is a direct replacement with a 0°C to +70°C temperature range. The MAX1090AEEI offers the same -40°C to +85°C range but with ±0.5 LSB INL accuracy compared to the ±1 LSB of the B-grade device.
