Recommended Driver Amplifiers for the AD7682
- For low frequency and low bias current, we recommend the ADA4627-1.
- For low noise and low frequency applications at medium supply voltages( up to +-13V), we recommend the AD8610, or the dual AD8620.
- For additional driver amplifier selections, we recommend selecting the product category and filtering on our parametric search tables.
- For low drift and high current output applications, we recommend the ADR430 family.
- For low drift and lower cost sensitive applications, we recommend the ADR440 family.
- For additional voltage reference selections, we recommend filtering on our parametric search tables.
- For low dropout regulators with inputs up to 5V, we recommend the low noise ADP151 or the low power ADP160.
- For high current switching regulators with inputs up to 5V, we recommend the low noise ADP2114.
- For additional voltage regulator selections, we recommend selecting the product category and filtering on our parametric search tables.
- For a 4-channel, 150Mbps data rate, we recommend the ADuM3441.
- For a 4- channel, 90Mbps data rate, we recommend the ADuM1401.
- For a 3-channel, 90 Mbps data rate, we recommend the ADuM1301.
- For additional digital isolator selections, we recommend filtering on our parametric search tables.
- For selecting voltage regulator products, use ADIsimPower.
