MAX1090BCEI+

Analog To Digital Converters (ADC) Overview

The MAX1090BCEI+ is a low-power, 10-bit analog-to-digital converter (ADC) featuring a successive-approximation register (SAR) architecture. It operates with a single +5V analog supply and supports a logic supply ranging from +2.7V to +5.5V via the VLOGIC pin. The device integrates an on-chip clock, a +2.5V internal reference, and an 8-channel input multiplexer. It offers a byte-wide parallel interface and achieves a maximum sampling rate of 400ksps with a power consumption of 10mW. The component is housed in a 28-pin QSOP package and is rated for an operating temperature range of 0°C to +70°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel analog input multiplexer supporting software-configurable unipolar or bipolar operation modes.
• Features a high-speed byte-wide parallel interface compatible with standard microprocessors.
• Includes an internal +2.5V bandgap reference and a 6MHz full-power bandwidth track-and-hold stage.
• Supports dual power-down modes to minimize current consumption between conversions.

Analog To Digital Converters (ADC) Applications

• Industrial control systems
• Data logging equipment
• Patient monitoring devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BCEI+' against official documentation to confirm the ±1 LSB INL/DNL accuracy grade and the 0°C to +70°C commercial temperature range. Ensure the ordering code matches the exact package type and performance specifications required for the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution and 400ksps throughput are required within a small footprint. Consider the integrated multiplexer and reference if external components must be minimized. Verify that the parallel interface timing requirements align with the host processor capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1090/MAX1092 family of 10-bit ADCs. The MAX1090 variant provides eight input channels, whereas the MAX1092 offers four. Both share similar architectures but differ in pin count and channel availability. The MAX1090BCEI+ specifically denotes the higher accuracy grade within the commercial temperature range.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1091 series serves as a pin-compatible alternative offering +3V operation. For designs requiring tri-stating of the INT signal, the MAX1060/MAX1064 families are recommended replacements.
