LM613 www.ti.com SNOSC11B – AUGUST 2000 – REVISED MARCH 2013 APPLICATION INFORMATION VOLTAGE REFERENCE Reference Biasing The voltage reference is of a shunt regulator topology that models as a simple zener diode. With current Ir flowing in the “forward” direction there is the familiar diode transfer function. Ir flowing in the reverse direction forces the reference voltage to be developed from cathode to anode.
PAGE 20
LM613 SNOSC11B – AUGUST 2000 – REVISED MARCH 2013 www.ti.com Capacitors in parallel with the reference are allowed. See the Reference AC Stability Range typical curve for capacitance values—from 20 μA to 3 mA any capacitor value is stable. With the reference's wide stability range with resistive and capacitive loads, a wide range of RC filter values will perform noise filtering. Adjustable Reference The FEEDBACK pin allows the reference output voltage, Vro, to vary from 1.24V to 6.3V.

Output Voltage has Positive TC if R1 has Negative TC Figure 73. Diode in Series with R1 Causes Voltage Across R1 and R2 to be Proportional to Absolute Temperature (PTAT) Connecting a resistor across Cathode-to-FEEDBACK creates a 0 TC current source, but a range of TCs may be synthesized.

Proportional-to-Absolute-Temperature Current Source Figure 76. Negative-TC Current Source Reference Hysteresis The reference voltage depends, slightly, on the thermal history of the die. Competitive micro-power products vary— always check the data sheet for any given device. Do not assume that no specification means no hysteresis.

LM613 www.ti.com SNOSC11B – AUGUST 2000 – REVISED MARCH 2013 OPERATIONAL AMPLIFIERS AND COMPARATORS Any amp, comparator, or the reference may be biased in any way with no effect on the other sections of the LM613, except when a substrate diode conducts, see (1) in Electrical Characteristics. For example, one amp input may be outside the common-mode range, another amp may be operating as a comparator, and all other sections may have all terminals floating with no effect on the others.
