Small, Fast, Low-Cost, High-Resolution Integrating ADC

18-Bit μP-Based AD1170: Low Nonlinearity, 10-ppm Integral/4-ppm Differential; Automatic Calibration, No Trims, Programmable Resolution and Integrate Time

The AD1170 is a microprocessor-compatible and programmable high-resolution (to 18 bits) intergrating a/d converter. Its small (1.24" x 2.5" x 0.55" max) modular package contains a complete microcomputer-based measurement subsystem comprising a high-linearity charge-balancing (V/F) converter, a single-chip microcomputer, and a custom CMOS controller chip.
