The OPA2234 series low-cost op amps are ideal for single-supply, low-voltage, low-power applications. The series provides lower quiescent current than older OPA2234 . SBOS055. OPA703. SBOS180A. REF3025. SBVS032C. XTR115. SBOS124A. If you have questions about this or other Texas Instruments Data Figure 7 gives an example of an exter- nal reference circuit using a single-supply, low-power, dual op amp ( OPA2234 ). The external references can vary as long SBAS178B. 14 www.ti.com. FIGURE 7. Example for an External Reference Driver Using the Dual, Single-Supply Op Amp, OPA2234 . OPA2234 . A1. OPA2234 . R3. R4.
