USB-1208HS-4AO User's Guide Specifications

Power

Table 12. Power specifications

Parameter Condition Specification

Operating modes Bus-powered, USB 5 V supply

Supply current

(see Note 1)

Suspend mode <2.5 mA

Enumeration <100 mA

Run mode <500 mA

Power consumption

excluding analog and

digital outputs

Run mode 1.175 W max (235 mA input current)

Power available for +5 V,

AICKO, AOCKO, TMR,

analog outputs, and

digital I/O

Run mode 1.325 W max

The total power consumption for all external loads must be less than this

value, and each load must meet the individual specification for the

terminal.

Digital output power

calculation

Power per output = Iout × 5 V

(for example, @ 24 mA, P = 0.024 × 5 = 120 mW / output)

Analog output power

calculation

Power per output = (Iout × 16.5 V) / 0.78

(for example, @ 3 mA, P = (0.003 × 16.5) / 0.80 = 63.5 mW/output)

+5 V output power

calculation

Power (W) = Iout × 5 V

+5 V output voltage

range (see Note 2)

Run mode 4.25 V min, 5.25 V max

Suspend mode,

enumeration

0 V

+5 V output current Run mode, no

other output loads

265 mA max (1.325 W)

Fuses On USB supply 0452.750 - Littelfuse 0.750A NANO2® Slo-Blo® Subminiature Surface

Mount Fuse.

Spare fuse mounted in holder on PCB.

Note 1: This is the total current consumption for the USB-1208HS-4AO, including +5 V, digital output and

analog output currents (if supported).

Note 2: Output voltage range assumes input power is within specified limits.
