MAX1090ACEI+T

Analog To Digital Converters (ADC) Overview

The MAX1090ACEI+T is a low-power, 10-bit analog-to-digital converter (ADC) featuring a successive-approximation architecture. It operates with a single +5V analog supply and includes an on-chip clock, a +2.5V internal reference, and a byte-wide parallel interface. The device supports software-configurable unipolar/bipolar and single-ended/pseudo-differential inputs. It offers four channels in pseudo-differential mode or eight channels in single-ended mode. Power consumption is 10mW at the maximum sampling rate of 400ksps. Two software-selectable power-down modes reduce current to under 10µA. The component is housed in a 28-pin QSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrated track-and-hold stage with 6MHz full-power bandwidth
• Software-configurable input multiplexer for flexible channel selection
• Adjustable logic level interface compatible with +2.7V to +5.5V digital supplies
• Internal bandgap reference with external adjustment capability

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix ACEI corresponds to the commercial temperature range of 0°C to +70°C. Confirm the presence of the '+' designation indicates lead-free and RoHS compliance status. Ensure the ordering information matches the exact pin count and package style required for the target PCB layout.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution with high-speed parallel output is required. Consider the internal reference and clock features if minimizing external components is a priority. Evaluate the power consumption requirements against the available supply voltage and thermal dissipation capabilities of the 28-pin QSOP package.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1090/MAX1092 family of 10-bit ADCs. The MAX1090 variant provides eight single-ended or four pseudo-differential channels, whereas the MAX1092 offers four single-ended or two pseudo-differential channels. Both share similar electrical characteristics and interface protocols.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1091BCEI+T is a pin-compatible +3V version within the same product family. Verify voltage compatibility and channel configuration differences before substitution.
