Description

<0>

OUT6 Delay

Bypass or use the delay function.

Bypass

<0> = 0; use delay function.

<0> = 1; bypass delay function.

<5:3> OUT6 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.

<5> <4> <3> Number of Capacitors

<2:0> OUT6 Ramp

Current

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

sets the delay full scale.

<2> <1> <0> Current (μA)

200

400

600

800

1000

1200

1400

1600

<5:0> OUT6

Delay Fraction

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

000000 gives zero delay.

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

<0>

OUT7 Delay

Bypass or use the delay function.

Bypass

<0> = 0; use delay function.

<0> = 1; bypass delay function.

<5:3> OUT7 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.

<5> <4> <3> Number of Capacitors
