Recommended References for the AD7799
- In a non-ratiometric application, we recommend the ADR381 or the ADR391 low noise, low power 2.5V reference.
- For low noise and low power applications, we recommend the ADA4051-2.
- For more precision and great temperature dirft specs, we recommend AD8539.
- For higher supply voltages up to +-8V, we recommend AD8639.
- For selecting voltage regulator products, use ADIsimPower.
- For selecting supervisor products, use the Supervisor Parametric Search.
