MAX1290BCEI+T

Analog To Digital Converters (ADC) Overview

The MAX1290BCEI+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 high-speed 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. Power consumption is 10mW at the maximum sampling rate of 400ksps. It utilizes a 28-pin QSOP package and features a VLOGIC pin for digital supply interfacing from +2.7V to +5.5V.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature range and linearity specifications. Ensure the component matches the required package type and voltage ratings for the target application environment before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution with 400ksps sampling rate is required alongside low power consumption. Consider the 28-pin QSOP footprint and the need for a +5V analog supply. Evaluate the internal reference stability and parallel interface requirements against system constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1290/MAX1292 family of 12-bit ADCs. The MAX1290 variant provides eight input channels, while the MAX1292 offers four. Both share similar architectures but differ in channel count and package size, with the MAX1290 utilizing a 28-pin QSOP.

Analog To Digital Converters (ADC) Replacement Considerations

For pin-compatible +3V versions, refer to the MAX1291/MAX1293 data sheet. Verify electrical characteristics and interface compatibility before substituting with other ADC models.
