Texas Instruments recommends a star-ground layout, with the REF3112AIDBZRG4 placed close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC) it is providing a reference voltage to. The device should be placed on a quiet, low-impedance power plane, and decoupling capacitors should be placed close to the device.
To ensure stability and accuracy over temperature, it is recommended to use a low-ESR decoupling capacitor (e.g. 10uF ceramic capacitor) and to keep the device away from heat sources. Additionally, the REF3112AIDBZRG4 has a built-in thermal hysteresis circuit that helps to maintain stability over temperature.
Yes, the REF3112AIDBZRG4 can be used as a voltage reference for multiple devices, but it is recommended to buffer the output voltage with an op-amp or a dedicated buffer amplifier to prevent loading effects and ensure accurate voltage regulation.
The REF3112AIDBZRG4 has a built-in power-on reset (POR) circuit that ensures the device is in a known state during power-up. It is recommended to power up the device after the power supply has reached a stable voltage, and to power down the device before the power supply voltage drops below the minimum operating voltage.
The recommended input voltage range for the REF3112AIDBZRG4 is 4.5V to 18V, but the device can operate with input voltages as low as 3.8V and as high as 20V. However, the output voltage accuracy and stability may be affected at input voltages outside the recommended range.
