MAX1292ACEG+

Analog To Digital Converters (ADC) Overview

The MAX1292ACEG+ 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 analog inputs for unipolar/bipolar and single-ended/pseudo-differential operation, offering four input channels in single-ended mode or two in pseudo-differential mode. Power consumption is 10mW at the maximum sampling rate of 400ksps. It utilizes a 24-pin QSOP package and functions within a temperature range of 0°C to +70°C.

• Touchscreens

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ACEG+' against official documentation to confirm the operating temperature range of 0°C to +70°C and the 24-pin QSOP package type. Ensure that the ordering information matches the exact component designation required for the application environment. Cross-reference datasheet revision details to validate pin configurations and electrical characteristics prior to procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution with a 400ksps sampling rate is required in a compact form factor. The integrated +2.5V reference simplifies design by eliminating external components. Consider the software-configurable input modes for flexibility in signal conditioning. Verify that the system's digital supply voltage falls within the specified VLOGIC range to ensure proper interface compatibility.

Analog To Digital Converters (ADC) Part Context

The MAX1292 belongs to the MAX1290/MAX1292 family of low-power, 12-bit ADCs manufactured by Analog Devices / Maxim Integrated. While the MAX1290 offers eight channels in a 28-pin package, the MAX1292 provides four channels in a smaller 24-pin QSOP footprint. Both devices share identical core specifications regarding resolution, speed, and power management features.

Analog To Digital Converters (ADC) Replacement Considerations

For pin-compatible +3V versions, consult the MAX1291/MAX1293 data sheet. If tri-stating the INT output upon CS going high is not desired, refer to the MAX1262/MAX1264 as an alternative.
