Description

0x0A0

OUT4 delay bypass

Bypasses or uses the delay function.

0: uses delay function.

1: bypasses delay function (default).

0x0A1

[5:3]

OUT4 ramp capacitors

Selects the number of ramp capacitors used by the delay function. The combination of the

number of the capacitors and the ramp current sets the delay full scale.

Number of Capacitors

4 (default)

[2:0]

OUT4 ramp current

Ramp current for the delay function. The combination of the number of capacitors and the ramp

current sets the delay full scale.

Current (µA)

200 (default)

400

600

800

1000

1200

1400

1600

0x0A2

[5:0]

OUT4 delay fraction

Selects the fraction of the full-scale delay desired (6-bit binary).

A setting of 000000b gives zero delay.

Only delay values up to 47 decimals (101111b; 0x2F) are supported (default = 0x00).

0x0A3

OUT5 delay bypass

Bypasses or uses the delay function.

0: uses delay function.

1: bypasses delay function (default).

0x0A4

[5:3]

OUT5 ramp capacitors

Selects the number of ramp capacitors used by the delay function. The combination of the

number of the capacitors and the ramp current sets the delay full scale.

Number of Capacitors

4 (default)
