MAX1292BCEG+T

Analog To Digital Converters (ADC) Overview

The MAX1292BCEG+T is a low-power, 12-bit analog-to-digital converter (ADC) featuring a successive-approximation register (SAR) 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 digital supply voltages 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) Feature Summary

• Software-selectable power-down modes enable rapid wake-up and reduced current consumption between conversions.
• Integrated track-and-hold stage with user-adjustable logic levels for direct interfacing with various digital supplies.
• Configurable analog input multiplexer supporting both single-ended and pseudo-differential signal acquisition.

Analog To Digital Converters (ADC) Applications

• Industrial Control Systems
• Data-Acquisition Systems
• Patient Monitoring

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm that the 'B' grade meets the required linearity specifications for the application. Ensure the operating temperature range aligns with the system environment requirements before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX1292BCEG+T when four single-ended or two pseudo-differential channels are required. Compare against the MAX1290 if eight channels are needed. Consider the MAX1291/1293 series if a +3V supply voltage is preferred over the +5V requirement of this device.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1290/MAX1292 family of 12-bit ADCs. It shares architectural similarities with the MAX1262/MAX1264 but differs in interrupt tri-stating capabilities. The MAX1292 specifically provides four single-ended channels, whereas the MAX1290 provides eight.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1290BCEG+T is a pin-compatible alternative within the same package offering eight channels instead of four. For +3V operation, the MAX1291BCEG+T or MAX1293BCEG+T serve as functional substitutes with adjusted supply requirements.
