Analog Devices Inc. AD5592R 12 位可配置模数转换器/数模转换器
亚德诺半导体 AD5592R 12 位可配置模数转换器/数模转换器配有八个 I/Ox 引脚 (I/O0 至 I/O7) ，使设计人员可单独配置为数模转换器(DAC)输出、模数转换器(ADC)输入、数字输出或数字输入。AD5592R/AD5592R-1 集成了一个 2.5V、25 ppm/°C 基准（默认关闭）和一个温度指示器（指示裸片温度）。温度值回读为模数转换器读序列的一部分。AD5592R/AD5592R-1 采用 16 引脚、2 mm x 2 mm WLCSP 和 16 引脚 3 mm x 3 mm LFCSP 两种封装， 工作温度范围为 -40°C 至 +105°C。 AD5592R/AD5592R-1 12 位可配置模数转换器/数模转换器非常适合用于控制与监控，及通用模拟&数字 I/O 应用。
When configuring an I/Ox pin as an analog output, the pin is driven by a 12-bit DAC. The DAC provides an output range of 0V to VREF or 0 V to 2 × VREF. When configuring an I/Ox pin as an analog input, the pin is connected to a 12-bit ADC via an analog multiplexer. The input range of the ADC is 0V to VREF or 0V to 2 × VREF. The ADC delivers a total throughput rate of 400kSPS. Designers can also configure the I/Ox pins as digital, general-purpose input or output (GPIO) pins. The designer can indicate the state of the GPIO pins as a set or read back by accessing the GPIO write data register or the GPIO read configuration register, respectively, via a serial peripheral interface (SPI) write or read operation.
The AD5592R/AD5592R-1 also includes an integrated 2.5V, 25 ppm/°C reference, which is turned off by default, and an integrated temperature indicator to provide an indication of the die temperature. As part of an ADC read sequence, the temperature value is read back.
Available in 16-ball, 2mm × 2mm WLCSPs and 16-lead, 3mm × 3mm LFCSPs packaging, the AD5592R/AD5592R-1 operate over a temperature range of −40°C to +105°C. The AD5592R/AD5592R-1 12-Bit Configurable ADC/DACs are well-suited for control and monitoring and general-purpose analog & digital I/O applications.
Analog Devices offers the EVAL-AD5592R-1SDZ evaluation board to help designers quickly prototype new AD5592R-1 circuits and reduce design time.
