FIGURE 8. Stacked References.

NOTES: (1) REF10s can be stacked to obtain voltages in multiples of 10V.

(2) The supply voltage should be between 10n +5 and 10n +25 where n is

the number of REF10s. (3) Output current of each REF10 must not exceed

its rated output current of

±10mA. This includes the current delivered to the

lower REF10.

FIGURE 11. +10V Reference with Output Current Boost

Using a Resistor to Drive a 600

Ω Bridge.

At 10V, the 600

Ω bridge requires 16.7mA. An 820Ω resistor connected

directly from the bridge to the positive supply provides the bulk of the bridge

current. The REF10 need only supply an error current to keep the bridge at

10V. Since the REF10 can sink or source up to 10mA, the circuit shown can

tolerate supply variations of up to 24V,

±8V, or bridge resistance drift from

400

Ω to 1400Ω.
