8 通道、200 ksps 至 500 Ksps、12 位 A/D 转换器

 

描述

The ADC128S052x device is a low-power, eight-channel CMOS 12-bit analog-to-digital converter specified for conversion throughput rates of 200 kSPS to 500 kSPS. The converter is based on a successive-approximation register architecture with an internal track-and-hold circuit. It can be configured to accept up to eight input signals at inputs IN0 through IN7.

The output serial data is straight binary and is compatible with several standards, such as SPI, QSPI, MICROWIRE, and many common DSP serial interfaces.

The ADC128S052x may be operated with independent analog and digital supplies. The analog supply (VA) can range from 2.7 V to 5.25 V, and the digital supply (VD) can range from 2.7 V to VA. Normal power consumption using a 3-V or 5-V supply is 1.6 mW and 8.7 mW, respectively. The power-down feature reduces the power consumption to 0.06 µW using a 3-V supply and 0.25 µW using a 5-V supply.

The ADC128S052x is packaged in a 16-pin TSSOP package. The ADC128S052 is ensured over the extended industrial temperature range of –40°C to +105°C while the ADC128S052-Q1 is ensured to an AECQ100 Grade-1 automotive temperature range of –40°C to +125°C.
