8.2.1 Design Requirements

Table 8-1 lists the BOM components required for the application. Table 8-2 lists other requirements for the

application.

Table 8-2. Design Parameters

PARAMETER

CONDITION

SPECIFICATION

VDD supply current(1)

VDD Y-bridge disabled, 48ksps mode, all

blocks enabled

< 15mA

VDD Y-bridge disabled, 96ksps mode, all

blocks enabled

< 20mA

IOVDD supply current

1.8V mode

< 1mA

3.3V mode

< 1mA

LC filter cut-off frequency(2)

Optional EMI filter

Fc > 2.4MHz

LC filter inductor

Optional EMI filter

L_IND > 4*VBST/(pi*Fc)

(1)

When VDD Y-bridge is enabled, additional power taken from VDD supply based on the selected switchover threshold voltage and the

output load impedance.

(2)

In I2C mode, VDD Y-bridge feature can be disabled to use lower LC filter cut-off frequency.
