MAX1295BEEI

Analog To Digital Converters (ADC) Overview

The MAX1295BEEI is a low-power, 12-bit analog-to-digital converter (ADC) featuring a successive-approximation architecture. It operates on a single +2.7V to +3.6V supply and includes an internal +2.5V reference and a 3MHz track/hold stage. The device supports a sampling rate of 265ksps with a power consumption of 5.4mW at maximum speed. It offers six single-ended or three pseudo-differential input channels in the MAX1295 variant. The component utilizes a high-speed 12-bit parallel interface and provides software-selectable unipolar/bipolar modes. It is housed in a 28-pin QSOP package and functions within a temperature range of -40°C to +85°C.

• Dual power-down modes enabling ultra-low standby current
• Three-state parallel digital interface for microprocessor compatibility

Analog To Digital Converters (ADC) Applications

• Industrial control systems
• Data-acquisition systems
• Patient monitoring equipment
• Energy management devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix EEI confirms the extended industrial temperature range (-40°C to +85°C) and ±1 LSB INL specification. Confirm the package type matches the 28-pin QSOP requirement for your PCB layout. Ensure the design accounts for the single +3V supply operation and parallel interface timing constraints during integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and moderate sampling speed are required alongside low power consumption. The MAX1295BEEI is suitable for designs needing a built-in reference and clock to minimize external components. Consider the 28-pin QSOP footprint and parallel interface requirements when choosing between this model and serial-output alternatives.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1295/MAX1297 family of low-power, 12-bit ADCs. The MAX1295 variant specifically provides six analog input channels, whereas the MAX1297 offers two. Both share identical electrical characteristics and interfaces, differing primarily in pin count and channel availability. The BEEI suffix denotes the industrial temperature grade and specific linearity performance.

Analog To Digital Converters (ADC) Replacement Considerations

Refer to the MAX1265/MAX1267 if tri-stating the INT signal upon CS deactivation is not desired. For pin-compatible +5V versions, consult the MAX1294/MAX1296 data sheet.
