The TC850 is a monolithic CMOS A/D converter (ADC) with resolution of 15-bits plus sign. It combines a chopper- stabilized buffer and integrator with a unique multiple- slope integration technique that increases conversion speed. The result is 16 times improvement in speed over previous 15-bit, monolithic integrating ADCs (from 2.5 conversions per second up to 40 per second). Faster conversion speed is especially welcome in systems with human interface, such as digital scales.
The TC850 incorporates an ADC and a µP-compatible digital interface. Only a voltage reference and a few, noncritical, passive components are required to form a complete 15-bit plus sign ADC. CMOS processing provides the TC850 with high-impedance, differentialinputs. Input bias current is typically only 30pA, permitting direct interface to sensors. Input sensitivity of 100µV per least significant bit (LSB) eliminates the
