MAX1295BCEI+T

Analog To Digital Converters (ADC) Overview

The MAX1295BCEI+T is a low-power, 12-bit analog-to-digital converter (ADC) featuring a successive-approximation register (SAR) architecture. It operates on a single +2.7V to +3.6V supply with a maximum sampling rate of 265ksps and power consumption of 5.4mW. The device includes an internal +2.5V reference, a 3MHz track/hold, and a 12-bit parallel interface. It offers six single-ended or three pseudo-differential input channels in a 28-pin QSOP package. Integral nonlinearity is ±1 LSB, and it supports software-selectable unipolar/bipolar modes.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 12-bit SAR ADC with internal clock and +2.5V reference
• Software-configurable multiplexer for single-ended and pseudo-differential inputs
• Fast wake-up capability with two selectable power-down modes
• High-speed byte-wide parallel digital interface

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 suffix 'E' indicates the extended temperature range (-40°C to +85°C). Confirm the 'C' variant corresponds to the commercial range (0°C to +70°C) if lower thermal limits are acceptable. Ensure the '+T' designation matches the required reel packaging format for automated assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 265ksps throughput are required within a constrained power budget. The integrated reference and clock simplify circuit design compared to external alternatives. Verify that the 28-pin QSOP footprint fits the available board space and that the parallel interface aligns with the host microprocessor's data bus width.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1295/MAX1297 family of precision ADCs from Maxim Integrated. The MAX1295 variant provides six input channels, whereas the MAX1297 offers two. Both share identical electrical characteristics and pinouts relative to their channel counts, facilitating scalable design across different application complexity levels.

Analog To Digital Converters (ADC) Replacement Considerations

Refer to the MAX1294/MAX1296 datasheet for pin-compatible 12-bit versions operating at +5V. Consider the MAX1265/MAX1267 if tri-stating the INT signal upon CS deactivation is not desired.
