MAX1293BEEG+

Analog To Digital Converters (ADC) Overview

The MAX1293BEEG+ is a low-power, 12-bit analog-to-digital converter (ADC) featuring a successive-approximation architecture. It operates on a single +3V analog supply and includes an internal +2.5V reference and on-chip clock. The device provides four software-configurable analog input channels supporting unipolar/bipolar and single-ended/pseudo-differential modes. It utilizes a byte-wide parallel interface for direct connection to microprocessors. Key electrical parameters include a maximum sampling rate of 250ksps, ±0.5 LSB integral nonlinearity, and power consumption of 1.9mA at full speed. The component is housed in a 24-pin QSOP package with an operating temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BEEG+' against the manufacturer's current ordering information to confirm the exact pin-compatible variant, temperature grade, and packaging configuration. Ensure that the required logic voltage levels align with the VLOGIC pin specifications before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 250ksps sampling rate are required within a compact 24-pin QSOP footprint. It is suitable for designs needing a single +3V supply and integrated reference circuitry. Consider the parallel interface requirements and ensure the host system can accommodate the necessary control signals for the byte-wide data bus.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1291/MAX1293 family of precision ADCs. While the MAX1291 offers eight channels in a 28-pin package, the MAX1293 provides four channels in a smaller 24-pin QSOP. Both share identical core performance characteristics, including linearity and power efficiency, differing primarily in channel count and physical dimensions.

Analog To Digital Converters (ADC) Replacement Considerations

For pin-compatible +5V versions, refer to the MAX1290/MAX1292 datasheet. Verify compatibility if a different channel count or package style is acceptable for the design.
