ADADC71 Rev. C is a complete, high-resolution 16-bit A/D converter with reference and clock. Its features include maximum nonlinearity of ±0.003%, no missing codes up to 14 bits, fast conversion speed, low power consumption, etc. The product is suitable for applications in medical and analytic instrumentation, precision measurement for industrial robots, automatic test equipment, multi-channel data acquisition systems, servo-control systems, etc.
The ADADC71 is a hybrid 16‑bit analog‑to‑digital converter that includes reference, clock, and thin‑film scaling resistors in a compact 32‑lead ceramic DIP. It provides parallel TTL‑compatible digital outputs and supports a variety of input voltage ranges for both unipolar and bipolar applications, making it suitable for medical instrumentation, industrial robots, test equipment, and data‑acquisition systems.
Key features include a typical conversion time of 35 µs for 14‑bit resolution, low power consumption (645 mW typical), industry‑standard pinout, and guaranteed no missing codes up to 14 bits. The device also offers short‑cycle capability, adjustable gain and offset, and an external clock option for slower conversion rates.
