MAX1290ACEI+T

Analog To Digital Converters (ADC) Overview

The MAX1290ACEI+T is a low-power, 12-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 inputs, offering eight channels in single-ended mode or four in pseudo-differential mode. It provides fast wake-up capabilities and two software-selectable power-down modes to minimize current consumption during idle periods.

Analog To Digital Converters (ADC) Feature Summary

• Integrated +2.5V bandgap reference and internal oscillator for simplified system design
• Software-configurable analog input multiplexer supporting multiple channel and polarity configurations
• User-adjustable logic level interface compatible with digital supplies ranging from +2.7V to +5.5V
• Dual power-down modes enabling significant reduction in supply current between conversions

Analog To Digital Converters (ADC) Applications

• Industrial control systems
• Data acquisition systems
• Patient monitoring equipment
• Energy management applications

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. Ensure the component matches the required package type and pin configuration for the target PCB layout. Cross-reference the datasheet revision to validate electrical characteristics and timing parameters before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution with a 400ksps sampling rate is required within a single-supply +5V environment. Consider the internal reference and clock features if external components must be minimized. Evaluate the power-down current specifications against system battery life requirements and verify that the parallel interface timing aligns with the host microprocessor capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1290/MAX1292 family of precision ADCs manufactured by Analog Devices/Maxim Integrated. The MAX1290 variant specifically provides eight analog input channels, whereas the MAX1292 offers four. Both share identical core conversion architectures and interface protocols, differing primarily in channel count and package pin density.

Analog To Digital Converters (ADC) Replacement Considerations

For pin-compatible alternatives operating at +3V, consult the MAX1291 and MAX1293 data sheets. Verify that any substitute maintains the same 12-bit resolution, SAR architecture, and parallel interface compatibility to ensure seamless integration without schematic modifications.
