Description
Digital Reset Input.
BUSY Input/Output (Active Low). BUSY is open-drain when an output. See the BUSY and
LDAC Functions section for more information.
DAC Outputs. Buffered analog outputs for each of the 40 DAC channels. Each analog
output is capable of driving an output load of 10 kΩ to ground. Typical output impedance
of these amplifiers is 0.5 Ω.
Reference Ground for DAC 0 to DAC 7. VOUT0 to VOUT7 are referenced to this voltage.
Reference Ground for DAC 8 to DAC 15. VOUT8 to VOUT15 are referenced to this voltage.
Reference Ground for DAC 16 to DAC 23. VOUT16 to VOUT23 are referenced to this voltage.
Reference Ground for DAC 24 and DAC 31. VOUT24 to VOUT31 are referenced to this voltage.
Reference Ground for DAC 32 to DAC 39. VOUT32 to VOUT39 are referenced to this voltage.
Reference Input for DAC 0 to DAC 7. This reference voltage is referred to AGND.
Reference Input for DAC 8 to DAC 39. This reference voltage is referred to AGND.
