MAX1020BETX+

ADCs/DACs - Special Purpose Overview

The MAX1020BETX+ is a mixed-signal integrated circuit combining an 8-channel, 10-bit analog-to-digital converter (ADC) and an octal, 10-bit digital-to-analog converter (DAC). It operates on a single +4.75V to +5.25V supply with a 225ksps conversion rate and 2µs DAC settling time. The device includes an internal 4.096V reference, a ±1°C accurate temperature sensor, and four configurable GPIOs. Data handling is supported by a 16-word FIFO and channel-scan modes via a 25MHz SPI-compatible serial interface.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 8-channel ADC and 8-channel DAC with 10-bit resolution
• Internal 4.096V reference voltage for ADC and DAC operations
• On-chip FIFO storing 16 ADC results and one temperature result
• ±1°C accurate internal temperature sensor

ADCs/DACs - Special Purpose Applications

• Controls for optical components
• Base-station control loops
• System supervision and control
• Data-acquisition systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix ETX corresponds to the 36-pin TQFN-EP package and 4.096V internal reference configuration. Confirm that the component meets RoHS compliance standards as indicated in the manufacturer documentation. Ensure the operating environment remains within the specified -40°C to +85°C temperature range during deployment.

ADCs/DACs - Special Purpose Selection Notes

Select this model when eight differential or sixteen single-ended ADC channels are required alongside eight DAC outputs. The MAX1020BETX+ is suitable for applications needing a 4.096V internal reference and a 5V supply rail. Consider alternative models like the MAX1057 if a lower 2.7V to 3.6V supply voltage or additional GPIO pins are necessary.

ADCs/DACs - Special Purpose Part Context

This component belongs to the MAX1020/MAX1022/MAX1057/MAX1058 family of multichannel ADCs/DACs. The MAX1020 variant specifically provides eight ADC channels and four GPIOs in a 36-pin package. It shares core architecture with the MAX1022, which offers twelve ADC channels but lacks GPIO functionality.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX1022BETX+ serves as a direct pin-compatible alternative offering 12 ADC channels instead of 8, though it omits the GPIO ports found in the MAX1020.
