Synopsis: The Voltage reference is based on the bandgap of silicon. It is designed in CMOS technology and uses the parasitic bipolars inherent in a CMOS process. The following table lists the key operating parameters.

Application Briefs: Typical application of the voltage reference is in data conversion A/D, D/A, temperature independent biasing of amplifiers, comparators, filters, PLLs and VCOs, charge pumps, doublers and other circuits where a temperature stable source may be required. An interesting application is in the generation of varying bias voltages or programmable regulators using the reference, a DAC and a voltage or current regulator. SPG has DACs and regulator cells for low and high voltage programmable bias source applications. Please ask us for information. Note: The output impedance of the core voltage reference is high. It is designed to work into a capacitive load, typically an analog buffer. Modifications to the core cell or additions to the core cell can be made by request.
