MAX1343BETX+

ADCs/DACs - Special Purpose Overview

The MAX1343BETX+ is a 12-bit multichannel data acquisition IC integrating an ADC, DAC, temperature sensor, and GPIOs. It features eight single-ended or four differential ADC channels with a 225ksps conversion rate and ±0.5 LSB INL/DNL accuracy. The device includes four 12-bit DAC outputs that settle within 2.0µs, exhibiting ultra-low glitch energy of 4nV·s. An internal 2.5V reference supports both the ADC and DAC. Power consumption ranges from 2.5mA at full speed to under 0.2µA in shutdown mode. It operates on a single +2.7V to +5.25V supply and utilizes a 25MHz SPI/QSPI/MICROWIRE serial interface.

ADCs/DACs - Special Purpose Procurement Notes

Verify the component against the official Analog Devices datasheet (Rev 1; 12/07) to confirm pinout compatibility and electrical specifications. Ensure the operating voltage range (+2.7V to +5.25V) matches the system design requirements. Check for RoHS compliance status as indicated in the manufacturer's documentation before finalizing procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this part when a compact solution combining high-speed analog input and precise output control is required. The MAX1343BETX+ is suitable for applications needing channel scanning and data averaging to reduce processor load. Consider the 36-pin Thin QFN package dimensions and thermal dissipation characteristics during PCB layout planning.

ADCs/DACs - Special Purpose Part Context

The MAX1343BETX+ belongs to the MAX1221/MAX1223/MAX1343 family of 12-bit multichannel ADCs/DACs. It shares the same core architecture and package as the MAX1221 and MAX1223 but differs in channel configuration, offering four DAC outputs compared to the MAX1221's eight.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX1221BETX and MAX1223BETX are pin-compatible members of the same family. Verify specific channel counts and GPIO availability when substituting these parts.
