7.4.1 Negative Reference Voltage
For applications requiring a negative and positive reference voltage, the REF31xx-Q1 and OPA703 can be used to provide a dual-supply reference from a ±5-V supply. Figure 7-5 shows the REF3125-Q1 used to provide a ±2.5-V supply reference voltage. The low drift performance of the REF31xx-Q1 complements the low offset voltage and low drift of the OPA703 to provide an accurate solution for split-supply applications.
