The ADADC80* 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.
Important performance characteristics of the ADADC80 include a maximum linearity error of ±0.012% at 25°C, maximum gain TC of 30 ppm/°C, typical power dissipation of 800 mW, and maximum conversion time of 25 μs. Monotonic operation of the feedback DAC guarantees no missing codes over the temperature range of −25°C to +85°C.
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.
