12位逐次逼近的集成电路模数转换器ADADC80数据表
分享资料个
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. 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.
