MAX1057BETM+

ADCs/DACs - Special Purpose Overview

The MAX1057BETM+ is a single-chip data acquisition system integrating a multichannel 10-bit ADC, an octal 10-bit DAC, a temperature sensor, and GPIO ports. It operates on a single +2.7V to +3.6V supply with a 225ksps conversion rate and 2µs DAC settling time. The device features ±0.5 LSB INL/DNL for the ADC and ±1 LSB INL for the DAC, utilizing a 2.5V internal reference. Communication is handled via a 25MHz SPI/QSPI/MICROWIRE-compatible serial interface, supported by an on-chip FIFO and AutoShutdown mode for low-power operation.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 10-bit ADC with 8 differential or 16 single-ended channels and true-differential track/hold
• Octal 10-bit DAC with 2µs settling time, ultra-low glitch energy (4nV·s), and monotonic output
• On-chip FIFO storing 16 ADC results and one temperature reading
• Internal ±1°C accurate temperature sensor and 12 configurable GPIO ports

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 ordering suffix against the manufacturer's current documentation to confirm package type and lead-free status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the voltage supply range matches the +2.7V to +3.6V specification required for this variant.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX1057BETM+ when a single-supply (+2.7V to +3.6V) solution is required, distinguishing it from the MAX1020/MAX1058 which require +4.75V to +5.25V. Choose this part for applications needing 16 single-ended or 8 differential analog inputs alongside eight DAC outputs in a compact 48-pin TQFN-EP package.

ADCs/DACs - Special Purpose Part Context

This component belongs to the MAX1020/MAX1022/MAX1057/MAX1058 family of 10-bit multichannel ADCs/DACs. While sharing core architecture, the MAX1057 is distinct due to its lower voltage operating range (+2.7V to +3.6V) and integrated 2.5V internal reference, compared to the higher-voltage variants that use a 4.096V reference.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX1058BETM+ serves as a direct functional substitute within the same package but requires a +4.75V to +5.25V supply and utilizes a 4.096V internal reference instead of 2.5V.
