TC850 Datasheet PDF - Microchip Technology

General Description:
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.
