SUPPLY VOLTAGE AND BIAS CURRENT

The ADCA5191 employs a versatile circuit design, allowing system

designers to configure the supply voltage at the RFON connection

(Pin 18 and Pin 19) and the RFOP connection (Pin 22 and Pin 23),

as well as the overall bias current of the device through the BIASA

and BIASB pins (Pin 11 and Pin 30).

Connect the BIASA and BIASB pins as shown in Figure 41. Keep

the network of passive components between the BIASA and BIASB

pins and VDD close to the device package to minimize parasitics.

Figure 41. Suggested BIASA and BIASB Application Circuit

Figure 42 provides the typical transfer function of IDD to RBIAS,

which allows the user to adjust IDD from 250 mA to 530 mA.

See the Typical Performance Characteristics for performance under

different bias conditions.
