Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltages are with respect to the GND pin.
The package thermal impedance is calculated in accordance with JESD-51.
The maximum power dissipation is a function of TJ(MAX), RθJA, and TA. The maximum allowable power dissipation at any ambient
temperature is PD = (T J(MAX) - TA) / RθJA. All numbers apply for packages soldered directly onto a PCB.

9 Detailed Description
9.1 Overview
The RS3112 is family of precision bandgap voltage references that are specifically designed for excellent initial
voltage accuracy and drift. See the Functional Block Diagram for a simplified block diagram of the RS3112.

11 / 18

www.run-ic.com

RS311210 Feature Description
10.1 Temperature Drift
The RS3112 is designed for minimal drift error, which is defined as the change in output voltage over temperature.
The drift is calculated using the box method, as described in Equation 1.
VOUTMAX-VOUTMIN
Drift = () ×106(ppm)
VOUT × Temp Range(1)

The RS3112 features a maximum drift coefficient of 20 ppm/°C.

10.2 Thermal Hysteresis
Thermal hysteresis for the RS3112 is defined as the change in output voltage after operating the device at 25°C,
cycling the device through the specified temperature range, and returning to 25°C. Thermal hysteresis can be
expressed as Equation 2:|VPRE-VPOST|
VHYST = () •106(ppm)
VNOM
where
• VHYST = thermal hysteresis (in units of ppm).
• VNOM = the specified output voltage.
• VPRE = output voltage measured at 25°C pretemperature cycling.
• VPOST = output voltage measured after the device has been cycled from 25°C through thespecified temperature range of –40°C to 125°C and returned to 25°C.
(2)

10.3 Noise Performance
Typical 0.1Hz to 10Hz voltage noise for each member of the RS3112 family is specified in the Electrical
Characteristics table. The noise voltage increases with output voltage and operating temperature. Additional
filtering can be used to improve output noise levels, although take care to ensure the output impedance does
not degrade performance.

10.4 Long-Term Stability
Due to aging and environmental effects, all semiconductor devices experience physical changes of thesemiconductor die and the packaging material over time. These changes and the associated package stress on
the die cause the output voltage in precision voltage references to deviate over time. The value of such change
is specified on the datasheet by a parameter called the Long-term stability (also known as the Long-Term Drift(LTD)). Equation 3 shows how LTD is calculated. Note that the LTD value will be positive if the output voltage
drifts higher over time, negative if the voltage drifts lower over time.
(VOUT|t=0 - VOUT|t=n)×106LTD(ppm)|t=n =VOUT|t=0
where
•
•
•

LTD(ppm)|t=n = Long-term stability (in units of ppm).
VOUT|t=0 = Output voltage at time = 0 hr.
VOUT|t=n = Output voltage at time = n hr.

RS311211 Device Functional Modes
11.1 Basic Connections
Figure 16 shows the typical connections for the RS3112. RUNIC recommends a supply bypass capacitor ranging
from 1 μF to 10 μF. A minimum 1μF output capacitor (CL) must be connected from VOUT to GND.

11.2 Supply Voltage
The RS3112 family of voltage references features extremely low dropout voltage. With the exception of the
VOUT<2.5V, which has a minimum supply requirement of 2.45 V, these references can be operated with a supplyof 300 mV more than the output voltage in an unloaded condition.

11.3 Negative Reference Voltage
For applications requiring a negative and positive reference voltage, the RS3112 and RS8651 can be used toprovide a dual-supply reference from a 5V supply. Figure 17 shows the RS3112 used to provide a 2.5V supply
reference voltage. The low drift performance of the RS3112 complements the low offset voltage and zero driftof the RS8651 to provide an accurate solution for split-supply applications. Take care to match the temperature
coefficients of R1 and R2.

Place the power-supply bypass capacitor as closely as possible to the supply and ground pins. The
recommended value of this bypass capacitor is from 1 μF to 10 μF. If necessary, additional decoupling
capacitance can be added to compensate for noisy or high-impedance power supplies.
Place a 1μF noise filtering capacitor between the NR pin and ground.
The output must be decoupled with a 1μF to 50μF capacitor. A resistor in series with the output capacitor is
optional. For better noise performance, the recommended ESR on the output capacitor is from 1 Ω to 1.5 Ω.
A high-frequency, 1μF capacitor can be added in parallel between the output and ground to filter noise andhelp with switching loads as data converters.

12.3 Power Dissipation
The RS3112 family is specified to deliver current loads of ±10 mA over the specified input voltage range. The
temperature of the device increases according to Equation 4:
TJ = TA + PD × θJA
where• TJ = Junction temperature (°C)
• TA = Ambient temperature (°C)
• PD = Power dissipated (W)• θJA = Junction-to-ambient thermal resistance (°C/W)(4)
The RS3112 junction temperature must not exceed the absolute maximum rating of 150°C.
