The ADADC801 is a complete 12-bit successive-approximation analog-to-digital converter (ADC) that includes an internal clock, reference, and comparator. Its hybrid IC design uses MSI digital and linear monolithic chips in conjunction with a 12-bit monolithic digital-to-analog converter (DAC) to provide modular performance and versatility with IC size, price, and reliability.
The design of the ADADC80 includes scaling resistors that provide an analog signal range of 2.5 V, 5.0 V, 10 V, 0 V to +5.0 V, or 0 V to +10.0 V. The 6.3 V precision reference can be used for external applications. All digital signals are fully DTL and TTL compatible; output data is in parallel form.
The ADADC80 is available in grades specified for use over the 25 C to +85 C temperature range and is available in a 32-lead ceramic DIP.
1. The ADADC80 is a complete 12-bit ADC. No external components are required to perform a conversion.
3. The internal buried Zener reference is laser trimmed to 6.3 V. The reference voltage is available externally and can supply up to 1.5 mA beyond the current required for the reference and bipolar offset.
4. The scaling resistors are included on the monolithic DAC for exceptional thermal tracking.
5. The ADADC80 directly replaces other devices of this type, providing significant increases in performance.
6. The fast conversion rate of the ADADC80 makes it an excellent choice for applications requiring high system throughput rates.
7. The short cycle and external clock options are provided for applications requiring faster conversion speed or lower resolution.
