Recommended Driver Amplifiers for the AD7984
- For low frequency, precision, low bias current applications, we recommend the ADA4627-1, ADA4610-2, or the AD8476.
- For precision, low power, low distortion applications, we recommend the ADA4841-1, ADA4940-1 or the ADA4941-1.
- For high frequency, low noise, low distortion applications, we recommend the ADA4899, ADA4897-1, or the AD8021.
- For additional driver amplifier selections, we recommend selecting the product category and filtering on our parametric search tables.
- For low drift, low noise and high current output applications, we recommend the ADR435 reference family.
- For low drift, low noise and low dropout, we recommend the ADR445 reference family.
- For low drift, low noise, low power, we recommend the ADR4550 reference family.
- For additional voltage reference selections, we recommend filtering on our parametric search tables.
Recommended Digital Isolators for the AD7984
- For SPI Interface, lowest power, 2.5 kVrms isolation, we recommend the ADuM1401.
- For SPI Interface, enhanced system-level ESD performance, 2.5 kVrms isolation, we recommend the ADuM3401.
- For SPI Interface, low power, 5.0 kVrms isolation, we recommend the ADuM4401.
- For SPI Interface, smallest package, low voltage I/O (1.8 V to 5.5 V), we recommend the ADuM3481.
- For additional digital isolator selections, we recommend filtering on our parametric search tables.
- For selecting voltage regulator products, use ADIsimPower.
- For selecting supervisor products, use the Supervisor Parametric Search.
