A current-to-voltage converter (usually a trans-impedance amplifier with low-leakage input) measures the test strip current, with an optional second-stage voltage signal conditioner before analog-to-digital conversion.This application uses two 12-bit DAC modules: one for the test-strip-driven voltage and the other for audio source generation. Figure 4 shows a BGM application block diagram using three smart analog combo SAC-L3 configurations.
