MAX1046BETX+T

ADCs/DACs - Special Purpose Overview

The MAX1046BETX+T is a 36-pin Thin QFN integrated circuit featuring a 10-bit, 225ksps analog-to-digital converter (ADC) and a quad 10-bit digital-to-analog converter (DAC). It includes an internal ±1°C accurate temperature sensor, a 16-sample FIFO, and configurable GPIOs. The ADC supports four single-ended or two differential channels with true-differential track/hold. The DAC outputs settle within 2.0µs with low glitch energy of 4nV·s. Operating on a +4.75V to +5.25V analog supply and +2.7V to AVDD digital supply, it consumes 2.5mA at maximum throughput and under 0.2µA in shutdown mode.

ADCs/DACs - Special Purpose Feature Summary

• 10-Bit ADC with 225ksps conversion rate, ±0.5 LSB INL/DNL, and no missing codes
• Quad 10-Bit DAC with 2.0µs settling time, 4nV·s glitch energy, and 0.5nV·s digital feedthrough
• On-chip FIFO storing 16 ADC results and one temperature result
• Internal 4.096V reference and ±1°C accurate temperature sensor

ADCs/DACs - Special Purpose Applications

• Closed-loop controls for optical components and base stations
• System supervision and control
• Data-acquisition systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the suffix '+T' indicates tape-and-reel packaging as per standard Maxim Integrated conventions. Confirm RoHS compliance status through official documentation. Ensure the specific lot number matches the required manufacturing date code for production integration.

ADCs/DACs - Special Purpose Selection Notes

Select this model over the MAX1040BETX when only four ADC input channels are required instead of eight. Choose this part if GPIO functionality is not needed, distinguishing it from the MAX1042BETX which includes four GPIO ports. Verify that the 36-pin Thin QFN package dimensions fit the target PCB layout constraints.

ADCs/DACs - Special Purpose Part Context

This component belongs to the MAX104x family, which integrates multichannel ADCs and DACs with FIFO capabilities. The MAX1046 variant specifically provides four ADC channels, whereas the MAX1040 offers eight. All variants share the same core architecture, including the quad DAC and temperature sensor, differing primarily in channel count and GPIO availability.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible substitutes within the same family include the MAX1040BETX (8 ADC channels), MAX1042BETX (4 ADC channels, 4 GPIOs), and MAX1048BETX (4 ADC channels, 4 GPIOs). Ensure the replacement matches the required ADC channel count and GPIO configuration.
