The ADADC71 and ADADC72 are high resolution 16-bit hybrid IC analog-to-digital converters including reference, clock, and laser-trimmed thin-film components. The package is a compact 32-pin hermetic ceramic DIP. The thin-film scaling resistors allow analog input ranges of ±2.5, ±5V, ±10V, 0 to + 5V, 0 to + 10V, and 0 to + 20V.
