MAX1090AEEI+

Analog To Digital Converters (ADC) Overview

The MAX1090AEEI+ 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 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.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm temperature range and linearity specifications. The 'A' suffix indicates ±0.5 LSB INL performance, while the 'E' suffix denotes an extended industrial temperature range of -40°C to +85°C. Ensure compatibility with the required package type and voltage levels before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution with high speed and low power consumption is required. The MAX1090AEEI+ is suitable for applications demanding multiple analog input channels and flexible input configurations. Consider the internal reference and clock features if external components are to be minimized. Verify that the parallel interface matches the target system's data bus requirements.

Analog To Digital Converters (ADC) Part Context

The MAX1090AEEI+ belongs to the MAX1090/MAX1092 family of 10-bit ADCs. It is pin-compatible with the MAX1092, which offers fewer input channels. For +3V operation, refer to the MAX1091/MAX1093 series. The device is available in a 28-pin QSOP package, designed for space-constrained applications requiring efficient power management.

Analog To Digital Converters (ADC) Replacement Considerations

For pin-compatible alternatives with different voltage requirements, consider the MAX1091 or MAX1093. If tri-stating the INT output is not desired, the MAX1060 or MAX1064 may be suitable replacements. Ensure any substitute maintains the required 10-bit resolution and sampling rate specifications.
