MAX1058BETM+T

ADCs/DACs - Special Purpose Overview

The MAX1058BETM+T is a mixed-signal integrated circuit featuring a 10-bit, 225ksps analog-to-digital converter (ADC) and an octal, 10-bit digital-to-analog converter (DAC). It includes a temperature sensor with ±1°C accuracy, a 16-entry FIFO, and 12 configurable GPIOs. The device operates on a single +4.75V to +5.25V supply and utilizes a 25MHz SPI/QSPI/MICROWIRE-compatible serial interface. Key performance metrics include ±0.5 LSB ADC INL/DNL, ±1 LSB DAC INL, and ultra-low glitch energy of 4nV·s for the DAC outputs.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 10-bit ADC with 16 single-ended or 8 differential channels and true-differential track/hold
• Octal 10-bit DAC with 2µs settling time, low glitch energy (4nV·s), and programmable power-up states
• Internal 4.096V reference, ±1°C accurate temperature sensor, and 16-word FIFO buffer
• 12 configurable GPIO ports and AutoShutdown mode reducing current to under 0.2µA

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 against official documentation to confirm package type and temperature range. Confirm RoHS compliance status as indicated in the datasheet revision history. Ensure the ordering code matches the required voltage range specifications for the MAX1058 variant.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX1058BETM+T when a 5V analog supply is available, distinguishing it from the MAX1057 which supports 3V operation. Choose this component for applications requiring multiple DAC outputs with fast settling times and high-accuracy multichannel ADC input within a compact 48-pin TQFN package.

ADCs/DACs - Special Purpose Part Context

This part belongs to the MAX1020/MAX1022/MAX1057/MAX1058 family of 10-bit multichannel ADCs/DACs. The MAX1058 specifically targets 5V systems, whereas the MAX1057 is designed for 3V applications. Both share identical pinouts and functional blocks but differ in operating voltage ranges and internal reference voltages.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX1057BETM serves as a direct pin-compatible alternative for designs operating at 2.7V to 3.6V instead of 4.75V to 5.25V. Verify that the system power supply aligns with the replacement's voltage requirements before substitution.
