24-bit ADC from Maxim offers 23.9-bit effective resolution

Maxim has unveiled the MAX11210, a single-channel, 24-bit ADC that offers 23.9-bit effective resolution (ENOB) at < 300µA. The MAX11210 meets power budget (500µA, max) for 4-20mA loop sensors and is suggested for portable instrumentation, temperature sensors, and other precision sensor applications.

The MAX11210 offers four general-purpose input/output (GPIO) lines, and integrates buffer amplifiers on the analog and reference inputs. The four GPIO lines can be used to control an external 16-channel multiplexer, converting the MAX11210 into a 16-channel ADC, thus eliminating up to four digital isolators. The MAX11210's integrated buffers eliminate the need for external buffers or gain stages.

The MAX11210 offers a software-programmable oversampling ratio for output rates up to 120sps with zero latency and up to 480sps in continuous-conversion mode. The ADC offers user-programmable offset and gain registers for enhanced system-level calibration where needed. Other integrated features include programmable gain from 1 to 16 and 100dB (min) 50Hz or 60Hz rejection.
