MAX1292AEEG+

Analog To Digital Converters (ADC) Overview

The MAX1292AEEG+ 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 and a +2.5V internal reference. The device supports a high-speed, byte-wide parallel interface and features a VLOGIC pin for direct interfacing with digital supplies ranging from +2.7V to +5.5V. Power consumption is 10mW at the maximum sampling rate of 400ksps. It offers software-configurable analog inputs for unipolar/bipolar and single-ended/pseudo-differential operation, providing four input channels in single-ended mode or two in pseudo-differential mode.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature range and package type. Ensure compatibility with existing system voltage requirements and interface protocols before procurement. Cross-reference part numbers with manufacturer databases to avoid counterfeit components.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 400ksps sampling rate are required within a compact QSOP package. Consider the internal reference and clock capabilities if external components must be minimized. Evaluate power constraints, as shutdown modes can reduce current significantly below operating levels.

Analog To Digital Converters (ADC) Part Context

This device belongs to the MAX1290/MAX1292 family of precision ADCs. It shares architectural similarities with the MAX1290 but differs in channel count, offering four single-ended inputs compared to the MAX1290's eight. It is designed for applications demanding low power and small footprint solutions.

Analog To Digital Converters (ADC) Replacement Considerations

For pin-compatible +3V versions, refer to the MAX1291/MAX1293 data sheet. Verify electrical characteristics and interface timing parameters when substituting with other SAR ADCs to ensure system compatibility.
